Model:SG250HX-20, rated 250kW high-power string pure grid-tied inverter

Product Features

1. High-efficiency generation

Maximum efficiency 99.03%, China efficiency 98.53%; 6 MPPT inputs adapted to various complex terrains; supports 1.1 times long-term overload at 35°C, raising yield even in high-temperature environments; maximum DC withstand voltage 1500V.

2. Reduced project investment

Supports aluminum cable connection, reducing AC cable cost; PLC communication removes the need for communication cables and cuts construction cost; fans support reverse rotation for dust removal, lowering air-duct maintenance frequency.

3. Safe and reliable

IP66 protection and C5 anti-corrosion, usable in harsh environments such as coastal areas and deserts; AC/DC terminal temperature detection identifies loose-connection risks; detects reverse-connected strings and can reverse-feed and trip the DC switch, giving multiple layers of safety protection; operating temperature -30°C to +60°C.

4. Smart and friendly O&M

Supports string detection and I-V scanning to quickly locate abnormal strings; MPPT-level DC insulation detection improves fault location accuracy by 6 times; power factor up to 0.9 at full output with night-time SVG reactive power compensation; supports Bluetooth APP, RS485 and PLC communication; smart forced air cooling.
