SolaX · 10.0 kW · 3-phase AC-coupled battery inverter
SolaX X3 FIT G4 10kW AC-coupled inverter
Where the supply is three-phase, the X3 FIT 10 is the SolaX retrofit route: a 10 kW AC-coupled battery inverter that brings HV storage to sites the single-phase FIT cannot serve. It is aimed at installers quoting storage for larger properties and light commercial buildings already generating on three phases.
Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment.
Description
Three-phase storage enquiries tend to come from bigger buildings with bigger loads, and this is the SolaX answer at 10 kW. For a firm already fitting the single-phase X1 FIT, adding the X3 version means one brand, one parts bin and one set of installation habits across both supply types, which is the practical argument for standardising on it. The surrounding SolaX accessories, from CT metering to communications dongles, sit in the same catalogue, so a three-phase job can be specified and ordered in one pass.

What it pairs with
On the battery side it sits with the SolaX Triple Power HV range, from single stacks up to the BMS parallel-box builds at 23.2 kWh and larger. Metering is the M3-40 three-phase CT energy meter, and the Pocket LAN 2.0 covers wired connectivity. Which Triple Power versions a given unit supports changes with model and firmware revisions, so confirm against SolaX's current pairing and stacking list.
This is a three-phase unit, so the property needs a three-phase supply; single-phase sites take the X1 FIT instead. No battery capacity is included: it is the inverter only. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.
