• The voltage and frequency at the connecting point should meet the grid connection
requirements.
• Additional protective devices like circuit breakers or fuses are recommended on the AC
side. Specification of the protective device should be at least 1.25 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.
