▲ NOTE!
All cable ends must be connected to battery terminals without
any washers between terminal bushings and cable ends.
Terminal burnout is caused by:
• Discharge currents exceeding allowable limits
• Improper cable installation
• Improper cable sizing
• Improper terminal torque
▲ NOTE!
Without exception, product experiencing terminal burn out
will not be warranted.
5.5 Parallel Battery Wiring
To ensure proper balancing and load sharing between parallel batteries refer to the wiring diagram below. Lithium batteries are
very sensitive to voltage and undersized battery cables will impede battery and system performance. The thickness (cross section) of
cable used should exceed the recommended minimum for the inverter charger installation whenever possible.
Five or more batteries in parallel should be installed using a busbar conguration. In a busbar conguration all battery cable sets
should be the same length regardless of the battery’s proximity to the busbar (or combiner box). Actual wiring requirements may
vary. Consult with the authority having local jurisdiction.
