How does the solar battery calculator work?

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.

How do I choose a charge controller for my solar panels?

To choose the correct charge controller for your solar panels and battery bank, you will need to assess the current, or amperage specs, of your solar panels. You can calculate this by dividing the wattage rating of your solar panels with the voltage. For example, a 100 watt solar panel / 12V = 8.3 Amps.

What is the voltage of a battery bank in off-grid solar power systems?

Usually, in off-grid solar power systems, the voltage of the battery bank is equal to the nominal voltage of the solar panels or solar panel array.
