SolaX Triple Power HV 5.8kWh slave battery
Existing Triple Power HV V3 tower running out of headroom? This heated 5.8kWh LFP slave is the extension module that stacks against a V3 master to add capacity. It is the part to quote when a storage customer's consumption has outgrown the original design.
Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment.
Description
Extension work is where module-level stock pays. One slave lifts a V3 tower by 5.8kWh without touching the rest of the system, so the revisit is short and the quote stays narrow. The heated LFP build is the same generation as the V3 main battery it partners, so the tower stays consistent module to module. For firms with V3 systems accumulating in the service book, a slave or two on the shelf turns capacity upgrades into routine work rather than special orders.

What it pairs with
Its natural partner is the Triple Power HV 5.8kWh heated main battery MASTER V3, the module every V3 tower starts with. The T58 battery cables and the T58 communication cable listed alongside make up the interconnects. Slave-to-master pairing is revision-specific, so keep V3 slaves on V3 masters and confirm the stack against SolaX's current pairing list.
A slave extension only: it does not operate without a V3 master in the tower. Each module adds 5.8kWh. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.
