please do make sure the grounding wire connects to the ground. the grounding resistor resistance should be
less than 10w for inverter of 380 v  level .
welding machine or other power equipment . the wire diameter shall conform with the stipulation of electric
equipment technical standard' and the wire should be as short as possible . in the occasion where two inverters are used at the same time' please do not make the grounding wire establish a loop. please find below for the correct grounding method and the wrong grounding method.
