Why you should buy a Solar Generator.
Vance Lupher
Independent Installations

This is an update of a post from last year.

Because you can! Twenty years ago producing your own electricity wasn’t even an option. If I build now power has to be part of the package. Solar electric power is so easy and economical that it would be foolish to do otherwise.

Last year PENELEC had a 15% rate hike and it’s just the beginning. All kinds of products from edge trimmers to cars are switching from gasoline to electricity. The price of electricity is going up, a lot. The price of purchasing a Solar Generator is stable or going down. Property owners need to produce some, or all, of their own electricity. If demand increases quick enough you may not be able to have power unless you make power. That may be an exaggeration but in places where the grid hasn’t kept up with technology it has already happened.

Anyone can buy or build an off grid plug and play Solar Generator or PowerStation. Once you have it set up it is nearly maintenance free. Generally, you don’t have to mess with it unless the batteries get drained. All you need is a clear view of the sun to the south.

You can start making a portion of the electricity you use and have power during outages. A 3kw Solar Generator or PowerStation can be as cheap as $5500 (if you are a DYI person) and produce an average of 430kwh per month for 20 years. This is a good size for a barn, garage, camp or part of your house because it will run everything except a hot water tank, electric range or dryer. That’s $5500 to power your garage, barn or camp with no further charges. For the cost of 2nd hand car you have electricity for 20 years or more with no monthly bill. If you get the right package it can be expanded when you have cash for it

A Solar Generator is a practical solution for property owners to power water wells, a garage, barn or camp. It can be used to supplement power in the residence and provide electricity when the grid is down. A Solar Generator is good for property owners and creating an independent lifestyle.

Solar PowerStations

Independent Installations

There are two main types of Solar PowerStations or Solar Electric Generators. They are Grid Interactive or In Grid and Independent or Off Grid. Here is a quick explanation of each one.

Grid Interactive Solar PowerStations are wired into the commercial grid that brings electricity to your home. They are simply an array of solar panels, an inverter and a meter. This type of Solar PowerStation uses the grid like a battery. It draws power from the grid when it can’t make electricity. The meter tracks how much electricity you produce and how much you use. Many states have Net Metering which means that you will be paid if you produce more electricity than you use. The good part is that your electric bill will be reduced. Most home owners finance their PowerStations and the payments are still less than their electric bills. Unfortunately, when the grid goes down so does your electricity. This protects repairmen from injury while repairing the outage. Most installers offer a back up battery bank that solves this problem. This is the most common Solar Electric PowerStation for homes in the market today.

Off Grid Solar PowerStations are NOT wired into the commercial grid. They are stand alone units. There are a wide variety of Independent Solar PowerStations. Some are just solar panels wired to an appliance. Most Off Grid PowerStations have an array of solar panels that charge a battery bank which feeds an inverter that you draw electricity from to power your appliances. Off Grid Solar PowerStations come in all sizes for a variety of uses and are extremely versatile. They can be as small as part of a backpack to charge phones or large enough to power an entire household. The amount of available electricity is limited to how much power your PowerStation can produce. Those yard lights with a solar panel on top are Off Grid Solar PowerStations. Once you pay for an Independent Solar PowerStation there is no continuing bill. The power you produce is yours.

Both types of Solar PowerStations are reliable and safe to use. Each one has it’s practical application. They are economical and sustainable. They make it possible for everyone to produce some of the electricity they use.

Why you should buy a Solar Electric PowerStation.
Vance Lupher
Independent Installations

Let’s just start with “Because you can!” Twenty years ago producing your own electricity wasn’t even a practical option. In today’s market, if I’m going to put up a building it’s going to produce it’s own power. Solar electric power is so easy and economical that it would be foolish to do otherwise.

The price of electricity from the grid is going up. PENELEC just announced a 15% rate hike and it’s just the beginning. It’s not hard to notice that all kinds of products from edge trimmers to cars are switching from gasoline to electricity. That means that the price of electricity is going to go up, a lot. The price of purchasing a Solar PowerStation is stable or going down. Property owners need to start producing electricity. If demand increases quick enough you may not be able to have power unless you produce power. That may be an exaggeration but in places where the grid hasn’t kept up with technology it has already happened.

Anyone can buy or build a plug and play Solar PowerStation. Once you have a Solar PowerStation set up it is nearly maintenance free. Generally, you don’t have to mess with it unless the batteries get drained. All you need is a clear view of the sun to the south.

You don’t need to get a 2nd mortgage to have a Solar PowerStation. You can start by making a portion of the electricity you use. A portable 2 kilowatt PowerStation cost around $2500 and is completely plug and play. The next practical size is a 5 kilowatt Solar PowerStation for around $5500. This is a good size for a barn, garage or camp because it will run everything except a hot water tank. That’s $5500 to power your garage, barn or camp with no further charges. For the cost of the installation of a pole & a meter you have electricity for 20 years or more with no monthly bill. If you get the right package it can be expanded up to 30 kilowatts of battery for about $4,000 every 5 kilowatts. You will need space for 24 solar panels. That will run your house.

That makes Solar PowerStations a practical option for Property Owners with out buildings or want to supplement their home use.

Along with my interest in off grid solar generated power I have other skills that my neighbors may find valuable.

I am 62 years old, engaged to my love, Ali Ford, and have a Bachelor’s Degree in Fine Arts. I was part of a nationally, award winning, staff at the Erie Art Museum, Erie, PA for 23 years. I managed the permanent art collections for 18 years and installed exhibits for 23 years. I supervised work crews that included employees and volunteers and did a lot of interior painting, wood working, art installations and handyman repairs. When I was let go last June due to the pandemic I decided to build a business around those skills.

Interior painting is my favorite work. Wall repair and working with a variety of wall types is my specialty. Generally, I work alone. I will bring in my son or granddaughter on a larger job. I can help you choose your colors and clear the room. When the painting is done, I can help you put your room back together. As a handyman, I am best at those pesky repairs like when your folding door doesn’t work or a leaky spigot. I can install handrails, build or assemble shelving, assemble furniture, design and install closets, replace door hardware and much more. I am pretty good at figuring out why something doesn’t work, if I can fix it. Who can fix it if I can’t. I enjoy helping clients get their projects accomplished.

When you have a project message, text or call me. I would really like to help you out.

About Discount LiFePO4 Batteries
Vance Lupher, Independent Installations

Lithium Iron Phosphate batteries are the current trend for off grid solar electric generator’s battery banks. There are 3 main reasons: available power (85%), longevity (2,000 to 7,000 cycles) and weight (a 100ah LiFePO4 battery weighs around 15lbs).

Battery banks are always the largest expense in Solar PowerStations and LiFePO4 batteries cost more. They have been around for several years so there are premium and discount brands. A premium LiFePO4 12vdc 100ah battery will cost between $850 to $1200. Larger battery banks are more cost effective. Rack mount 48vdc 5kw batteries are available for between $1600 and $3000. A discount LiFePO4 12vdc 100ah battery will cost between $320 and $500.

All the brands of discount LiFePO4 batteries are from China. Some are good and some aren’t. Fortunately, there are several You Tube guys who test these products. I have noticed that groups of products are constructed the same, are produced in the same factories and sold at different price points.

Here is some general knowledge about discount LiFePO4 batteries that will help you get started. LiFePO4 batteries are regulated by a Battery Management System or BMS. The BMS will need to be activated. Generally, this is done by charging the battery with a LiFePO4 14.6v battery charger. A standard lead acid battery charger will not do. Follow the directions on how to activate the BMS in the manual. Do not connect a LiFePO4 battery to a solar charge controller until the BMS is activated. That may damage the battery. Do not connect batteries in series before the BMS is activated or the BMS may be damaged. Do not assemble a battery bank of 2 to 4 batteries until the BMS of each battery is activated and the batteries are balanced, that is charged to exactly the same voltage. Once the batteries BMS are activated and they all have the same charge you can build your battery bank and connect it to the inverter. Then you can connect the charge controller.

Finally, buy the size of discount LiFePO4 battery you need and follow the directions on activating the BMS. It will save you a lot of time, especially if you are a novice If you are building a 24v or 48v battery bank buy 24v or 48v batteries. It will cost a little more but it will save you a lot of headaches. If you are building a PowerStation between 1 and 5 kilowatts you can buy a battery to fit your need. It will drive you crazy building a huge battery bank from 12v 100ah batteries if you don’t have the right equipment.

My Solar Electric Generator
600w Solar Array 2kw PowerStation

At the end of my last post I said it would be the last one for this page because A-1 Solar Electric Projects had been absorbed into my business, Vance Lupher, Independent Installations. I lied. I like this page too much. I am going to start posting my other projects here but not today. Today’s post is for Gary Decker who wants to know the components of my Solar Electric Generator is made of.

A Solar Electric Generator consist of 2 basic sections, the Solar Array and the PowerStation. I have a 600w Solar Array made up of 6 Renogy 100w solar panels, an ECO-PV4, 250v 40a combiner box and an 80’ 6UF wire cable that carries my current into the PowerStation. The basic components of a PowerStation are a charge controller, a battery bank and an inverter. My PowerStation consist of a TD2307 250v max 40a MPPT charge controller that is protected by a 40a marine circuit breaker. The charge controller does exactly that, it regulates the charge of the battery bank so it doesn’t get damaged from under or over charge. I have a new 24v 100ah Lithium Iron Phosphate (LiFePO4) battery bank which stores up to 2kw of usable power. I have a 70a Marine circuit breaker between the battery bank and everything else. I have a 100a bus bar to connect the negative lines. My inverter is a KRXNY 2000w 24vdc to 120vac.

What does all that mean? I have 2 kilowatts of stored electricity that I can access as standard 120vac. My inverter will deliver 2 kilowatts of power immediately (which would completely drain the battery bank). On a nice day the Solar Array will charge the battery bank from drained to fully charged in 4 to 6 hours and I can use power while my battery bank is charging so I will get much more than 2kw per day out of my generator, especially on a nice long summer day.

I built this unit as an exercise, to learn all the basic parts and how they function. I am so happy that it works the way it should and takes very little maintenance. I doubt if I will ever build a 2kw PowerStation from scratch again. You can buy a 2kw or 3kw PowerStation that is the size of a small suitcase and weighs about 45 lbs for very reasonable money and they are very user friendly. Plug them into a solar array that fits their specifications and you are in business.

I spent $2200 on a 2kw Solar Electric Generator that should work for 5 years before some part breaks down. That works out to $440 per year for guaranteed prepaid electricity. The longer it last the more cost efficient it gets. I don’t get why more people don’t produce some or all of their own electricity.

Good day!

This is my current solar electric generator and I am ready to give it a big upgrade. I am replacing my spent 24volt 100amphour SLA battery bank with a new Lithium Iron Phosphate one of the same size. I am really stoked about this. I put this old battery bank through the wringer. I mean, I really pushed it. When it was new it held about a kilowatt of stored power. After 5 years of hard use all it can do is balance the electricity from the panels during the day so I can use it. (Power from a solar array is wildly erratic depending on weather conditions so an off grid generator needs a battery bank to balance the power to the inverter.) As soon as the sun goes down the voltage drops to around 23.4volts so I know it’s not holding any usable power. I just turn the inverter off so it doesn’t completely drain the battery bank, damage a cell so the battery bank is ruined.

Changing to a 24v 100ah LiFePho4 battery bank is in line with what I planned for my PowerStation from the beginning. The solar array is 600w at 24v and the battery bank stores 2400watt hours of power. On a good day the array can charge these batteries from completely spent in about 5 hours. That’s about how much peak sunlight we get on a nice winter day. This battery bank can be drained to around 15% so it has around 2kw of usable power. This chemistry also lets you draw the power all at once if you want to so it will power anything that uses a 15amp circuit. For example, my 50” TV uses about 81w so this battery bank will power the TV for 24 ½ hours. Practical application is when I fall asleep during the 3rd quarter of Monday Night Football I won’t wreck my battery bank.

This is last post for A-1 Solar Electric Projects. A-1 Solar Electric Projects has been absorbed into my business, Vance Lupher, Independent Installations. I will still be posting about my solar electric projects as well as other things I am working on.

Introduction to Battery Banks
by Vance Lupher
For Gary Kinigsberg

This is my current battery bank. It consist of 2 Mighty Max 12volt 100amp hour SLA deep cycle batteries.

The battery bank has two basic functions in an off grid Solar PowerStation. The most obvious task is to store power for later use. Less obvious but more important is to stabilize the current. Electricity does not flow from a solar array in a smooth, consistent continuous flow. The flow of current can fluctuate wildly depending on the atmospheric conditions of the moment. The battery bank provides a consistent voltage to support and even out the erratic supply from the solar array. Even if you are running a direct current system you still need a battery bank so that your appliances will run smoothly. Nobody enjoys trying to read in flickering lights.

Batteries have certain terms to describe them. Batteries are rated by their voltage and amp hours. Batteries contain and distribute direct current voltage (vdc). For a small off grid PowerStation 12vdc (volts direct current) at 100ah (amp hours) is a good size. 100Ah describes how many amps are available over time at 12vdc. A cycle is one revolution of charging and discharging a battery. The Depth of Discharge (DOD) is the amount of charge left in the battery before it is charged. The State of Charge (SOC) is the charge of the battery at any given time. DOD is particularly important because each battery chemistry has a bottom DOD and if you discharge the battery below that level you you will damage the battery. Each battery chemistry also has a range of cycles that it will last for. A lead acid battery will ideally last 1000 cycles if your DOD is no more than 50%.

Batteries have many electric chemical compositions. When assembling a battery bank you need deep cycle batteries as opposed to ignition batteries. The battery in your car is an ignition battery. They throw a fast powerful charge but don’t last over time. I am going to talk about 3 of the most common deep cycle batteries: SLA, AGM and LiFePO4 batteries.

SLA stands for Sealed Lead Acid. This is the oldest most common dependable deep cycle battery chemistry. It is a maintenance free version of a standard Lead Acid battery. SLA batteries are dependable and inexpensive. They can be put together in series or parallel circuits and they are pretty good in hot or cold weather. They are also maintenance free, keep the terminals clean and a decent air flow and your done. SLA batteries are heavy, a 100ah SLA weighs over 35lbs, they have a shorter life span, between 500 and 1000 cycles (or 3 to 5 years) and they loose efficiency below freezing. If they are discharged below their recommended DOD (usually between 50% & 60%) it really shortens their life span. Trust me on this one. What kind of power do you have? First, 60% DOD is more realistic than 50% if you want your battery to last. In my mind a 12vdc 100ah SLA has about 480wh (watt hours) of usable stored electricity. Remember, once your battery bank is charged power can be used on demand without discharging the battery. Generally you can get a battery like this for around $180.

AGM means Absorbed Glass Mat. This battery is a lead acid battery with fiberglass in it that absorbs the electrolyte (the acid). An AGM battery has most of the same properties of an SLA. An AGM can charge and discharge faster than an SLA. They are more resilient than an SLA. Their DOD is 50% so they have a little more available power. They are really heavy and they cost more than an SLA. A 12vdc 100ah AGM battery has about 600wh of usable stored power. You can get good AGM batteries like this between $200 and $300.

LiFePO4 is Lithium Iron Phosphate. These batteries have been around about 5 years. They are similar to Lithium Ion batteries but they last much longer. LiFePO4 batteries last between 2,000 to 5,000 cycles. Their DOD is around 20% so a 100ah battery has about 960w of usable stored power. That is almost a kilowatt. They weigh about a third of an SLA, 15lbs vs. 35lbs. They do not vent any gasses and they work in a wide temperature range. They do have some serious down sides. LiFePO4 batteries can’t be charged at freezing or below. It damages the battery immediately. The same if they get too hot, like 115ºf. Some of them cannot be used in parallel or series circuits because they have a cheap BMS (Battery Management System). They require a programmable charge controller, usually an MPPT (Maximum Power Point), which adds expense to your PowerStation. Finally, LiFePO4 batteries start at around $400 and go to $1200 so they are expensive.

So you have an RV on a remote property that you visit year round. You power it with a 100w solar panel with a 10a PWM charge controller and a 12vdc battery and your battery craps out. Your not planning to expand your system any time soon. What do you do? Your Solar panel produces between 250w and 600w of power per day. I would say to get either a 100ah SLA or AGM battery. An AGM if you have the cash. You can leave it hooked up year round as long as it is being charged by the panel it will be alright. The charge controller will trickle charge the battery so it is ready when you get there. You could buy a 50ah LiFePO4 and have the same efficiency with less weight but then you have to make sure the battery doesn’t freeze. An SLA or AGM battery is just less hassle in this situation.

If you decide to build a larger PowerStation that’s a different story for another post.

07/23/2021

I am always thinking of convenient uses for solar electricity. I recently had the opportunity to install a flag pole for my friends Tim & Judy. I planned to purchase a solar light to go with the flag pole. There are lots of brands of flag pole lights so I figured that I should be able to find a good one pretty easy. Rule #1 about solar products “If there are a lot of products to choose from most of them are merely adequate.” Nobody wants an “adequate” flag pole light.

I know quite a bit about lighting from my previous job, lighting exhibits at the Erie Art Museum. I didn’t expect to have much trouble with this. I completely underestimated companies ability to market mediocre products. I did a bunch of research and looked at dozens of products. It didn’t take long for me to notice that most of them didn’t include basic information in the advertising. Basic information on lighting includes: how bright the light is, what color the light is and how much power it takes. There were lots of videos, pictures and customer reviews (all positive) but not much real information.

I ended up with a product that didn’t really do the job. (here comes the rant) This is rampant in the solar electric industry. From poorly assembled lights to birdbath water pumps that don’t really work to cheap charge controllers that burn out in a month. It’s really bad for the industry. It promotes the myth that solar electric power isn’t dependable. This is a total falsehood perpetuated by industries that will eventually loose their customers to the solar electric industry. Crappy products produced by get rich quick companies support this myth when disaffected customers turn away from solar electricity due to the poor performance of the products.

I am on a search for a majestic solar flag pole light. I am looking at down lights and up lights. I would like to find a down light that works. It’s more convenient to have the light on the top of the pole where it is out of the way. A down light also reduces the amount of light pollution and makes it easier to see the stars. When I find one I think may be good I am going to get it and try it out on my flag pole. This could get expensive.

Tim & Judy light their flag with a 90watt halogen spot light that plugs into the wall. It’s majestic. You can see that in the picture.
