An inverter is required when you want to power AC devices. The inverter converts the DC power, or direct current, from the solar array and batteries into AC power.
Inverter serves essentially as the brain of the system. It extracts Power from the solar panels and runs the load with it. If batteries are present in the system (Hybrid or Off-Grid system), the inverter also charges batteries with this power. When the Solar Power is not available, it takes power from Grid or Batteries (depending upon the system type and configuration) and runs the load with it.
The details of the inverters that we use can found in the subsequent sections.
