SolaX Triple Power HV 5.8kWh master battery
Every Triple Power HV V3 tower begins with this module: the 5.8kWh heated LFP main battery. It is the first line on a new V3 storage order, and the heated build suits the colder install spots, garages and outbuildings, that UK storage often ends up in.
Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment.
Description
The master is the module that makes a V3 tower a system rather than a shelf of cells: capacity extensions hang off it, so it is the one part no V3 design can skip. Firms standardising on the V3 platform tend to hold a master and a couple of slaves, because that combination covers a new install and an upgrade from the same stock. Start at 5.8kWh with the master alone and let the slave count follow the customer's consumption. Supply is straightforward trade: UK stock, ordered online, invoiced plainly.

What it pairs with
Extend it with the Triple Power HV 5.8kWh heated LFP extension battery SLAVE V3, its matching capacity module, and connect the tower with the T58 battery and communication cables in this catalogue. On the inverter side the SolaX hybrid families cover X1 single-phase and X3 three-phase work. Pairing is generation-specific, so verify V3 combinations against SolaX's current stacking list.
One master per tower is the starting point; on its own it provides 5.8kWh, with growth coming from V3 slave modules. Pallet-only dangerous-goods delivery applies. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.
