Cables with a cross-section between 2.5 mm² and
6 mm² are compatible with the SUNCLIX plugs/
sockets.
The Bosch BPT-S series string inverters are equipped
with varistors on the DC side. These provide
overvoltage protection.
To minimise faults caused by overvoltages through
electric fields (e.g. in the event of storms): Avoid
looping (keep the enclosed area between the feed
and return line as small as possible).
