⚡ Key Features
-
20 kW rated AC output in a three-phase configuration — well-suited for larger residential, commercial or industrial three-phase solar + storage systems.
-
Supports low-voltage battery systems (typically ~40-60 V) with high charge/discharge currents for rapid energy cycling.
-
Dual MPPT trackers for flexible solar string configuration and maximised yield.
-
Wide PV string voltage range (start-up from ~160 V up to ~650-V MPPT) — accommodates large PV arrays.
-
100% unbalanced output capability — each phase can output up to half the rated power independently, offering load flexibility.
-
Parallel operation supported — up to multiple units in parallel for increased capacity and scalability.
-
IP65 rated enclosure — suitable for indoor or sheltered outdoor installation, designed for harsh environments.
