Installing Cables of a Battery System
(ch) Short circuit and ground fault protected installation is required up to the fuses. You can omit battery fuses if short circuit and ground fault protected installation is provided throughout, up to the stand-alone grid inverter. When selecting cable material, ensure that this is approved for short circuit and ground fault protected installation (e.g. cable type NSGAFöu).
Also note that battery acid can corrode the cable insulation. Therefore, use acid-resistant cable material at least for cables close to the batteries, and adhere to the information of the battery manufacturer.
All work on the inverter and the cabling of the PV array must be carried out by an electrically qualified person.
