Solar Panel And Battery Bank Calculator

Unfortunately we don t design systems for our customers but we do offer you the tools to design your own system.

Solar panel and battery bank calculator.

Because of the better efficiency and deeper discharge depth lithium battery banks tend to be only 50 60 of the size of a comparable lead acid bank. Voltage of your battery bank you already selected a voltage in the second input in the above calculator though you may change your mind either during this part or later. The off grid solar panel system calculator helps you size the battery bank watts of solar panels and the solar charge controller you need. Individual battery voltage each battery will have the same voltage and it ll likely be less than the battery bank voltage.

At a bare minimum most customers will have have a solar panel that can output two day of power in a single day and they will often select a battery that can withstand two days without solar and still not. The lithium batteries we use are purpose built for off grid solar and utilize a special lithium chemistry called lithium ferro phosphate lifepo4 commonly called lfp. For example 1200w drawn at 240v is only 5a whereas at 12v this current increases to 100a. Batterystuff tech i would suggest running your numbers into the calculator.

By using the very same solar battery calculator you can define as well the number of solar batteries connected in parallel if your solar battery bank is composed of solar batteries of voltage equal to solar panel nominal voltage i e solar power system voltage.
