It integrates a system manager with native access to Sunny Portal (ennexOS) to orchestrate up to five inverters (up to 135 kVA) and an Energy Meter, allowing dynamic control of active\/reactive power, phase balancing, and zero feed-in. Its 3 high-current MPPTs, ArcFix protection (AFCI), and the ShadeFix algorithm ensure optimal and safe performance even with partial shading and new generation modules.\u003c\/p\u003e\n\n\u003ch3\u003eMain Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal power 20 kW\u003c\/strong\u003e at 230\/400 V three-phase (50\/60 Hz) with PV oversizing up to approx. 30 kWp STC.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e3 independent MPPTs\u003c\/strong\u003e with \u003cstrong\u003e2 strings per MPPT\u003c\/strong\u003e, current per tracker of \u003cstrong\u003e24 A\u003c\/strong\u003e (Isc max. 35 A) and wide MPPT window for long strings.\u003c\/li\u003e\n  \u003cli\u003eMax.
