3.4 Grid connec�on and backup load connec�on
· Before connec�ng to grid, please install a separate AC breaker between inverter and grid. Also,
it is recommended that installs an AC breaker between backup load and inverter.This will ensure
the inverter can be securely disconnected during maintenance and fully protected from over
current. For the 3.6/5KW model, the recommended AC breaker for backup load is 32A/40A.
For the 3.6/5KW model, the recommended AC breaker for grid is 40A.
· There are three terminal blocks with "Grid" "Load"and "GEN" markings. Please do not misconnect
input and output connectors.
All wiring must be performed by a qualified personnel.It is very important for
system safety and efficient opera�on to use appropriate cable for AC input
