Solar inverter | V1.7
9.5.1 Wiring instructions
CAUTION
Ensure that the lengths of all battery cables are equal. Otherwise, there is a voltage
difference between the inverter and battery which will cause the parallel inverter to not
function.
CAUTION
Install a fuse on the battery and AC input side. This ensures that the inverter can be
safely disconnected during maintenance work.

nominal value of the fuse should be the n-fold of the current of 1 device. "X" stands for
the number of inverters switched on in parallel mode.
