requirements.
• Additional protective devices like circuit breakers or fuses are recommended on the AC
side. Specication of the protective device should be at least 1.6 times the maximum AC
output current.
• Make sure that all the grounding cables are tightly connected. When there are multiple
inverters, make sure that all the grounding points on the enclosures are equipotental
connected.
• You are recommended to use copper cables as AC output cables. A copper to aluminum
