Inverters

The main difference between a UPS, Backup inverter and solar inverter is that a solar inverter has a solar charge controller or MPPT. The MPPT controls and adjusts the input voltage to harvest the maximum amount of power from the solar array. MPPT or charge controls can be added to inverters that don’t have them built in.

Some solar inverters can also be used as a backup system without PV panels and charging batteries from the grid. With this type of inverter as a backup you have the option of adding panels later.
