Electric Wiring
1. Off-grid electric wiring (annex 1)
To ensure the safety and easy maintenance, please install the switch and fuse according to the
diagram. Make sure there are consistent among the output voltages of generator, battery voltage
and input voltage of inverter. A wire-connecting mistake will lead to burn down the generator,
batteries and inverter.
(Special attention to 3kw & above 3kw)
a. There are two cables elicited from the generator head. One is the cable of wind direction signal
with aviation plug on cable head. You need to insert it into the socket. The other cable is for the
output of generator power and controlling signal. There are five lines with three relative thick
ones for generator output and the other two relative thin ones for controlling signal, which is
