Power cables for linking batteries, inverters and storage modules: Growatt ARK cable kits for MOD and MIN-XH inverters, SolaX 1.2m power cables for T-BAT SYS HV 3.0 batteries, Weco busbar kits for low voltage parallel stacks and battery cables with lugs already fitted.
In a storage system the cables are not interchangeable: length, cross-section, connector type and polarity are the maker's, and on high voltage the connectors are quick-fit with a safety lock. Fitting a generic cable costs you the warranty, at best.
For made-to-measure runs the cross-section is worked out on maximum current and length, holding voltage drop inside 1%.
