What's included?
We supply 1.5m, 50mm² battery cables terminated with M8 ring lugs, suitable for direct connection between the battery and inverter, or via an external busbar. For correct installation, connect all negative conductors before attaching the positive.
The supplied cables are compatible with most inverters; however, in certain configurations, it may be necessary to route the battery cables to a busbar and then use the manufacturer-supplied inverter leads for the final connection.
A 1.5m communication cable is also included, enabling straightforward data integration.
