inverter/charger has dedicated grounding terminal as shown in Fig. 2-2⑤, the grounding must
be reliable, the grounding wire shall be the thicker wire (wire is not less than 4mm
grounding point shall be as close as possible to the inverter/charger, the grounding wire shall
be the shorter, the better.
