2�3 Inverter Safety
WARNING
• The voltage and frequency at the connecting point should meet the on-grid 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 groundings are tightly connected. When there are multiple inverters, make
sure that all the grounding points on the enclosures are equipotential bonding.
• The alarm can be cleared automatically if the inverter triggers a fault for less than 5 times within
24 hours. The inverter will shutdown for protection after the 5th electric arc fault. The inverter can
operate normally after the fault is solved.
•
BACK-UP is not recommended if the PV system is not configured with batteries. Otherwise, the
risk in system power usage is beyond the equipment manufacturer's warranty scope.
