Sunsynk · 8.0 kW · 1-phase hybrid inverter
Sunsynk Sun 8K ECCO hybrid inverter
The Sun 8K ECCO tops the ECCO single-phase hybrid line at 8kW. It is the unit to quote when household demand has outgrown a 5kW design and the property still sits on a single-phase supply.
Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment.
Description
Bigger arrays and heavier daytime consumption push plenty of surveys past the mid-size hybrids, and this is the ECCO answer without changing brand or platform. Installers already fitting the 3.6kW and 5kW versions will find the same family logic here, which shortens the learning curve on the heavier jobs. Holding one 8kW SKU for the top end of domestic work is simpler than mixing brands, and the flat ex-VAT trade price means the occasional big job costs no more per unit than the routine ones.

What it pairs with
Behind an 8kW hybrid most designs want meaningful capacity, so the 10.64kWh W10.6 white battery is the natural first pick, with 5.32kWh L5.3 or W5.3 units where the budget is tighter. Add the SDM120CT-M single-phase meter. Confirm the battery pairing against Sunsynk's current list, since it can vary by model and firmware revision.
Single-phase only, and above 3.68 kW this needs G99 approval before install. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.
