Description

A default inverter earns its place by being predictable: the same fitting routine, the same commissioning steps and the same paperwork on every job. Standardising on the H1 3.7 Gen 2 for routine installs means fewer surprises on site and a spares position you can actually manage. The EPS output is in the box on every unit, so adding backup later in the sale does not change the hardware. Trade pricing is flat here, so stocking two or three costs the same rate per unit as buying one.

What it pairs with

Partner it with Fox high-voltage battery stacks from the EQ or ECS series, and use the Fox single-phase wireless meter and CT where a wired meter run is impractical. A WLAN or LAN stick covers monitoring. Battery-to-inverter pairing depends on revision and firmware, so confirm against Fox ESS's current compatibility list before committing the design.

Single-phase only, rated at 3.68 kW. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.

FAQ

Fox ESS FE-H1-3.7-G2 buying questions

The price on this page is the ex-VAT trade rate, and 20% VAT is added when the invoice is raised. Quantity makes no difference to the unit rate: buy one for the job in hand or several for the van, and there are no minimums either way.
Parcel courier: no hazardous classification on this unit and no kerbside pallet to manage. Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment. That makes re-stocking the van a matter of ordering when the shelf looks thin rather than planning around freight.
20+ 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.
