Fox ESS · 1.5 kW · 1-phase single tracker PV inverter
Fox ESS S1500 1.5kW PV inverter
Replacement work is where the Fox ESS S1500 belongs: a 1.5 kW single-phase, single tracker PV inverter for swapping out a failed or ageing small inverter on an existing array. The panels and the design stay as they are; only the box on the wall changes.
Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment.
Description
Plenty of small arrays from the early solar years are still generating well, and when the original inverter gives up the array size rarely justifies an upgrade project. A 1.5 kW replacement keeps the system as designed and the invoice modest. The single tracker layout suits the simple string arrangements those older small systems tend to use, which keeps the swap uncomplicated. As with everything here, it is sold at a flat ex-VAT trade price, so a one-off replacement job carries no penalty for being a one-off.

What it pairs with
On a replacement job the useful add-on is monitoring the old unit never had: the Fox WLAN-WW stick is the usual pick, with the GSM stick as the fallback for connection-free sites. If the customer is minded to add storage later, Fox's AC charger inverters, such as the AC 3.7 kW Gen 2, sit on the AC side without disturbing the PV inverter. Check Fox's current pairing list for accessory and firmware matches.
Single-phase only, with a 1.5 kW output on a single tracker. It suits like-for-like swaps on small arrays rather than upsizing work. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.
