5.2 Safety
The Growatt Inverter must be connected to the AC ground from the utility via the
Ground Terminal (PE).
5.3
Connecting to the grid (AC utility)
5.3.1 GRID standards
IMPORTANT:
If several GROWATT are installed in a tree-phase AC GRID. it is
recommended to distribute the inverters between the phases in order to reduce the
power unbalances between the phases. Always refer to the local standards.
5.3.2
Connection of the AC wiring (AC output)
A Measure grid(utility) voltage and frequency. It should be 230 VAC(or
220VAC),50/60Hz and single phase.
B Open the breaker or fuse between PV Inverter and utility.
C For Inverter, connect AC wires as follows:
