3.
A separate Ground wire should bond the Inverter to the local ground
connection for personnel safety. By bonding at this location is easy for
operator to determine the inverter is safely grounded.
4.
Connect the AC (L1, L2, L3) cables to the copper bus bar and connect
the ground cable to the internal grounding terminal block.

When the output of the inverter is connected to the grid, an external AC circuit
breaker or fused disconnect deviceis required to be installed to safely disconnect
the inverter from the grid should an overcurrent occur. The minimum size breaker
is determined by NEC calculations. The internal temperature of the AC Panel
must be considered and appropriate derating applied to prevent nuisance tripping.
Inverter model
Max AC OCPD

Table 4-5 Specification of AC OCPD
The inverter operates at 800VAC output. If another voltage/configuration is
required, a transformer may be necessary.
