4.5 Battery isolation
The rules and guidelines for battery isolation vary in different countries, but, it is recommended, that if battery isolation is needed, to only isolate the positive battery cable. When a battery isolation switch is needed always make sure you use a quality battery isolation switch. A bad switch can cause a voltage drop. The battery switch must be rated to the currents that can be expected in the system under full load.
Type of battery isolator switches • Marine or automotive systems (usually 12 and 24V) use battery isolators • Land based systems (usually 48V) din mounted DC MCBs or blade fuses are used

Switching the negative in multiple unit systems Our inverter/chargers do not have galvanic isolation between the battery and VE-BUS. In a system with more than one inverter/charger it is extremely important to always follow below rules. Not following these rules can lead to damage to the communication chip.
