What does peak efficiency mean on a solar inverter?

Peak efficiency: An inverter's peak efficiency (also known as maximum efficiency) rating indicates how efficient the inverter is at converting the solar input (DC) energy into home electricity output (AC) energy when it's operating at its optimal (or rated) capacity.

Which solar inverter is best?

The SolarEdge Home Wave Inverter is our top pick. It was the most efficient inverter we looked at, meaning you'll get to use more of the energy your solar panels generate -- less waste means you'll have more power to use around the house.
