Do not connect loads between the inverter and the AC switch directly connected to the
inverter.
Install one AC output circuit breaker for each inverter. Multiple inverters cannot share
one AC circuit breaker.
An AC circuit breaker shall be installed on the AC side to make sure that the inverter can
safely disconnect the grid when an exception happens. Select the appropriate AC circuit
breaker in compliance with local laws and regulations.
When the inverter is powered on, the BACK-UP AC port is energized. Power off the
inverter first if maintenance is required on the BACK-UP loads. Otherwise, it may cause
electric shock.
For cables used in the same system, it is recommended that the conductor
material, cross sectional area, length, etc. of the cables should be consistent.
