Solar Panel And Battery Bank Calculator

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.

Solar panel and battery bank 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 year for your location. 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. For example 1200w drawn at 240v is only 5a whereas at 12v this current increases to 100a.

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. When using an inverter the current draw on the battery side can be extremely high so you may need a battery bank that is larger than the minimum. Individual battery voltage each battery will have the same voltage and it ll likely be less than the battery bank voltage. 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.

Please remember that this calculator works out the minimum battery bank size for a given power consumption.
