Just to note, this is a VERY small cabin with only a few electrical appliances! For reference, the average kWh usage per month for grid-connected homes in the US is 900 kWh! Amount of Back-up Power and Depth of Dischargeīatteries allow you to store the electricity your solar installation generates for later use, and after you find your daily electrical load, you need to decide how many days of backup power you want. Our total load for each day is 1.22 kWh and about 36.6 kWh a month. Our usage probably looks something like this: Item Along with the LEDs, blender, and laptop above, we’ll also have to power our cell phone, fans, TV, and clothes washer. The space heater, water heater, and stove are propane, so only a few key items need electricity. There are also many online tools to help you in this process, including calculators from websites like Wholesale Solar and Affordable Solar.Įxample: Let’s say we have a small off-grid mountain cabin.

To help you keep track, use a spreadsheet like Microsoft Excel or Google Spreadsheets (which is free with Gmail!).

50 watt laptop*6 hours per day = 300 watt-hours/dayĪs you can imagine, this process takes time and there are a lot of numbers to keep track of, so be sure not to rush this step! The size of your entire battery bank will be based on these calculations, so you need to make sure they are as accurate as possible!.

1500 watt blender*.05 hours per day = 75 watt-hours/day (I can’t go without my morning smoothies!).

5 LED light bulbs*8 watts (the wattage of each light bulb)*3 hours per day = 120 watt-hours/day.

In this case, you’ll need to calculate how much electricity you need by adding up the wattage of all the electrical devices in the home and estimating how many hours you’ll use them each day.

If you aren’t connected to the grid, you probably don’t have any data on your previous energy use.

If you are already connected to the grid, simply look at your total electricity use for the last 12 months and divide by 365 to get your daily average.

First, you can look at your previous electricity usage.

There are two methods to calculate your load: The first step in designing your DIY battery bank is calculating how much electricity you typically use -known as your electricity load. Use the information below as a starting point, but when the time comes to really start planning your DIY battery bank, be sure to check out a few books on the subject at your local library, browse relevant online articles and videos, and join a couple online forums for guidance and help with any questions you have!

Simply find the italics throughout each section to follow-along! To make the planning process a bit easier to understand, we’ve included a running example throughout the article. Thinking about installing batteries to go with your solar panels? No matter if it’s an off-grid mountain cabin or a battery back-up for your grid-connected homes, the basic process for planning designing your own DIY battery bank is fairly straightforward, but can be a bit confusing your first time around.īelow are the basic steps to planning and designing your own DIY battery bank to complement your solar installation.
