Solis S5-GR3P20K 20kW Three Phase ON-Grid Solar Inverter

Description

Solis S5-GR3P20K 20kW Three Phase ON-Grid Solar Inverter

Designed to optimize solar electricity yields for commercial headquarters, textile garment units, educational campuses, private hospitals, and medium-scale industrial rooftops across standard three-phase 380V/400V electrical grids, the Solis S5-GR3P20K on-grid string inverter represents the top-capacity model in Ginlong Solis’s 5th generation (S5) commercial string series. Certified and approved by the Sustainable and Renewable Energy Development Authority (SREDA), this inverter fully complies with Bangladesh’s official Net Metering guidelines, allowing commercial enterprises to feed substantial surplus clean electricity directly into the national grid for monthly utility tariff offsets.

The solar DC input stage features Dual Independent Maximum Power Point Trackers (MPPT) with 4 DC string inputs (2 strings per MPPT). Accommodating up to 30 kW of recommended DC array capacity, the system operates across a wide voltage window of 160V to 1000V (start-up at 180V). With an upgraded continuous DC input current capacity of 32A per MPPT (40A short-circuit current), it eliminates current clipping when paired with modern high-power 550W+ to 700W+ bifacial PV modules. Dual MPPT channels allow engineers to split solar strings across separate roof faces, tilts, or partial shading zones without mismatch losses.

Operational security and asset safety are anchored by integrated AFCI (Arc-Fault Circuit Interrupter) protection, which continuously analyzes DC current waveforms to detect and extinguish micro-arcing faults before electrical fire hazards can ignite. For commercial facilities awaiting net metering clearance or operating under strict utility feed-in limitations, the inverter features built-in Export Power Control (Zero-Export), automatically adjusting generation to real-time site load when connected to an external smart energy meter. It also features 24-hour consumption monitoring, multi-peak scanning for shaded arrays, and adaptive weak-grid algorithms for stable performance in remote industrial zones.

Built inside an IP66-certified weather-sealed aluminum enclosure, the inverter employs intelligent redundant fan cooling that automatically regulates operating temperatures under heavy ambient loads and operating temperatures ranging from –25 °C to +60 °C. Comprehensive remote fleet monitoring is accessible via SolisCloud through integrated RS485 communication or optional plug-and-play Wi-Fi / GPRS data logger sticks, supported locally by an integrated multi-segment LCD screen and front-panel status indicators.
