6.5 Connecting the Battery Cable
WARNING
• Connect the battery cables to the corresponding terminals such BAT+, BAT- and grounding
ports correctly. Otherwise it will cause damage to the inverter.
• Ensure that the whole cable cores are inserted into the terminal holes. No part of the cable
core can be exposed.
• Ensure that the cables are connected securely. Otherwise it will cause damage to the
inverter due to overheat during its operation.
• An external DC circuit breaker is recommended if there is no integrated DC circuit breaker
inside the battery. Recommended specications: 40A/600A.
DANGER
• The battery used with the inverter shall be approved by the inverter manufacturer. The
approved battery list can be obtained through the ocial website.
• A short circuit in the battery may cause personal injury. The instantaneous high current
caused by a short circuit can release a large amount of energy and may cause a re.
• Before connecting the battery cable, ensure the inverter and the battery, and
downstream&upstream switches, are all disconnected.
• It is forbidden to connect and disconnect the battery cables when the inverter is running.
Otherwise it may cause electric shock.
• Do not connect one battery pack to more than one inverter at the same time. Otherwise, it
may cause damage to the inverter.
• It is forbidden to connect loads between the inverter and batteries.
• When connecting battery cables, use insulated tools to prevent accidental electric shock or
short circuit to the batteries.
• Ensure that the open circuit voltage of the battery is within the permissible range of the
inverter.
NOTICE
• For Battery-Ready inverters, please contact the manufacturer or dealer to activate the
battery related functions rst if you need them. Do not connect any battery to the inverter
if the battery related functions are not activated. Otherwise the inverter will stop working.
• Ensure that the battery ports are sealed properly if there is no battery connected.
