What Is A Ground Fault Protection circuit?How Is The Inverter Grounding Done correctly?Grounding Systems For Off-Grid InvertersInverters are enclosed with an Aluminum heatsink to dissipate heat and are also fitted with a grounding terminal to the enclosure. A grounding wire of 6 AWG must be connected to the grounding terminal on the inverter and connected to a single-point grounding connection wire. If there is no suitable grounding connection point, then the grounding wir...See more on solvoltaics
