MPPT Solar Charge Controllers Explained

When charging 48V batteries, the system will need a string of at least 2 panels in series but will perform much better with 3 or more panels in series, depending on the maximum voltage of the charge controller. Since most 48V solar charge controllers have a max voltage (Voc) of 150V, this generally allows a string of 3 panels to be connected in series.

Solar Back-up Batteries & Power Cuts

This depends on the type of back-up system you have. Some lower cost batteries will automatically discharge their stored energy when a power cut is detected. This is in part due to the fact that the battery inverter is usually smaller than the solar inverter; allowing the energy in the solar inverter to flow into the battery could overload it.
