Solar Panel And Battery Bank Calculator

Power output calculator calculates the minimum recommended battery bank size in amp hours ah.

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. 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. Batterystuff tech i would suggest running your numbers into the calculator. The calculator assumes you will need to size your system to get you through average amount of sun light in the least sunniest month of the yearfor your.

The way the power is stated on devices isn t standard. 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. Unfortunately we don t design systems for our customers but we do offer you the tools to design your own system. The solar battery calculator applies the best practices for using the depth of discharge dod of different types of solar batteries thus ensuring the optimal compromise between the size of the battery bank and the desired long life of the batteries while taking into account their type.

In this case use the wattage calculator at the top of the solar battery bank calculator above to convert the current and volts to watts. Enter the daily power consumption in wh and check the other data change if necessary.
