The ability of an inverter to accurately convert DC to AC, operate within specified voltage and current limits, and incorporate safety and control features such as MPPT, transfer switches, and ground fault protec.
[pdf] Maximum system voltage is the maximum voltage at which your solar system array should be operated. This metric is crucial when you connect an inverter or controller to your array. So, why is this important.
[pdf] Most modern inverters have efficiency ratings between 90% and 98%. Let’s break it down: If you feed 1000 watts of DC power into your inverter and it outputs 950 watts of AC power, your inverter efficiency is 95%. The other 50 watts were lost in the conversion process—mostly as heat.
