Specifications

Eco is the AC-coupled variant with no PV/MPPT input. Manufacturer datasheet states AC output steps with added extension batteries: 1000 W base alone, 2000 W with one SFA1800, 2400 W with two SFA1800 or one SFA3600; perConfigOutputW capacities are approximate (base 1.792 kWh plus SFA1800 modules at ~1.792 kWh each). Per-unit hardware ceiling is 2400 W; up to 3 parallel groups give 7200 W system power and up to ~32.4 kWh. Round-trip efficiency conflicts across sources (retailers cite 79.2% and 81%, manufacturer page does not state it), so left null. Cycle life conflict: most sources and manufacturer state 8000 cycles; one retailer (StekkerDeal) listed 6000. Warranty mostly 10 years; one retailer listed 20 years. Capacity expandable to 10.752 kWh with up to 5 SFA extensions.
