Sunsynk ECCO 3.6kW hybrid inverter

The Sunsynk ECCO 3.6kW is a single-phase hybrid inverter that accepts up to 7kWp of PV. That headroom makes it a natural new-install spec where the customer wants a generously oversized array on a standard domestic supply.

Description

The draw here is the DC headroom. A 3.6kW rating with 7kWp of PV input lets you design big arrays for winter yield without moving up an inverter size, so the ECCO covers a large share of standard domestic work with one part number. It sits in the same ECCO family as the 5kW and 8kW units, which keeps the installation routine consistent as jobs scale. Stock is held in the UK and the page price is the invoice price, ex VAT.

What it pairs with

Pair it with Sunsynk's own storage, such as the 5.32kWh IP65 battery (SUNSYNK-L5.3) or the W5.3 wall units in black or white, and add the SDM120CT-M single-phase digital meter from the same catalogue. Battery pairing can vary by model and firmware revision, so check Sunsynk's current pairing list before you finalise the design.

Rated at 3.6 kW with PV input up to 7kWp, and single-phase only. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.

FAQ

Sunsynk SUN-3.6-ECCO buying questions

The ex-VAT trade price sits on this page, and VAT at 20% is added on the invoice. The figure does not move with volume: one inverter for a single job costs the same per unit as a stack for the store, with no minimum order to meet.
It travels with a parcel courier rather than pallet freight, so there is no need to plan for a kerbside drop. Expect 3–5 working days (estimate). The dispatch clock starts at cleared payment, so bank transfer clearing time is the main variable to allow for.
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.
