Solar power battery backup calculator. Solar battery backup calculator. The first step is determine your power needs. This number is entirely up to you and has no influence on the solar demand. Battery backup allows you to have all of the benefits of a grid tied solar system and to have power during a grid outage.

Input values below and click calculate to populate the other values on the page. Some batteries include a form of battery backup while for others it needs to be configured. Unlike gasoline generators powerwall keeps your lights on and phones charged without upkeep fuel or noise. The cost of solar battery backup varies depending on the battery the configuration of the system and the type of backup you require.

Backup power refers to the battery system assuming no solar whatsoever. The load calculator displays the ideal inverter battery combo for your home or commercial establishments. In order to calculate the battery backup time multiply the battery size in ah by the number of batteries needed by battery voltage usually 12v by battery efficiency rate usually 0 80 then divide your answer by your power load in watts. Luminous has a comprehensive range of inverter and batteries to fulfill your power backup requirement.

Best to budget for between 1 500 3 500 extra for solar battery backup depending on the level of backup you require. Check theinverter and battery price list before choosing a large or small inverter battery according to your specific needs. Check out our grid tied solar calculator to get started. Powerwall is a battery that stores energy detects outages and automatically becomes your home s energy source when the grid goes down.

5 hour reserve 12 hour reserve 1 day reserve 3 day reserve. 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. Calculate solar battery backup time. Use the following equations to determine solar array size and battery backup requirements based on 12v nominal system voltage.
