SolaX X1 Boost G4 3.0kW PV inverter

The X1 Boost G4 3.0T is SolaX's 3.0 kW single-phase dual-tracker PV inverter, a natural spec for a new install on a smaller domestic roof. Its two trackers take an array split across two faces or orientations, and it keeps the design simple where no battery is on the job sheet.

Description

Trade buyers keep coming back to string inverters like this when the brief is simple generation at a sensible outlay. The dual trackers let you split the array across two roof faces or orientations without giving up control of either string, which covers most awkward UK roofs. It is also a clean line to quote: the ex-VAT trade price on the page is the price you pay before VAT, one unit or a boxful, with no minimum order to plan around.

What it pairs with

Add a Solax Pocket WiFi 2.0 dongle for its web interface connection, and the Solax M1-40 single phase CT energy meter where the job calls for a CT meter. If the customer later wants storage, the SolaX X1 G4 RetroFit AC coupled battery inverter sits alongside a Boost on the AC side. Dongle and meter fit can depend on hardware revision, so check SolaX's current pairing list for your unit.

Single-phase only. This is a PV string inverter, not a hybrid, so it does not connect batteries directly. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.

FAQ

SolaX X1-BOOST-G4-3.0T buying questions

The ex-VAT trade price is displayed on this page, and VAT at 20% is added on the invoice. The price does not move with volume: one inverter for a single job costs the same per unit as a stack for the van, because we run no minimum order and no spend tiers.
It ships by parcel courier, since with no lithium content there are no dangerous-goods freight rules in play. Delivery is 3–5 working days (estimate). The dispatch clock starts at cleared payment, so for bank transfer orders that means from the point your payment clears.
14 in stock at the last catalogue update, and the count on this page comes from the live stock feed rather than a manual list. In stock means in stock; if the number reads zero, the trade desk can tell you the restock position for this part number.
UK trade buyers with a verified account: limited companies verify with a Companies House number, sole traders with a UTR, MCS or scheme number. No trade minimums — one unit at trade price, no annual-spend tiers.
