50kW Three-Phase Grid-Tied Solar Inverter (4 MPPT · IP66)

50kW Three-Phase Grid-Tied PV Inverter · 4 MPPT (IP66)

Product Overview
This 50kW three-phase grid-tied inverter is designed for residential rooftops and small-to-medium commercial PV plants. It comes standard with 4 independent MPPTs, a maximum input voltage of 1100V and an ultra-wide MPPT range of 160~1000V to adapt to complex grid conditions. Long/short string mixed configuration makes DC design flexible, with excellent module compatibility. Maximum efficiency reaches 98.6% (China efficiency 98.2%), and the global MPPT scanning algorithm boosts energy yield by about 2%. With IP66 protection, C5 anti-corrosion rating, smart air cooling, one-scan commissioning and APP cloud control, installation and O&M are effortless.

Key Features

• High yield: max. efficiency 98.6%, China efficiency 98.2%; global MPPT scanning effectively eliminates string mismatch losses, increasing yield by ~2%; power factor >0.99 at rated power, adjustable 0.8 leading ~ 0.8 lagging;
• Flexible design: 4 independent MPPTs support long/short string mixed configuration for highly flexible DC layout; ultra-wide MPPT voltage range 160~1000V adapts to complex grids; per-MPPT max. input current 40/40/32/32A — fully compatible with 20A high-current modules;
• Safety first: Type II surge protection on both DC and AC sides actively mitigates lightning risks; DC reverse-polarity protection, AC short-circuit protection, leakage current protection, grid monitoring, DC switch, string-level detection and anti-islanding protection are all built in;
• Built to last: IP66 enclosure with C5 anti-corrosion rating withstands heat, humidity and salt fog in coastal and harsh outdoor environments; operating temperature -25℃~+60℃; max. altitude 4000m (derating above 2000m);
• Easy O&M: one-scan smart commissioning for fast setup; LED + APP dual interface; 4G + RS485 communication for cloud-based remote monitoring, with anti-islanding and remote grid waveform recording;
• Grid friendly: rated output 50000W (max. 55000W / 55000VA) for 3-phase 230/400V and 220/380V grids; total current THD <3% and DC component <0.5% In for excellent power quality;
• Easy installation: compact body 645×595×245mm, only 40kg, transformerless design — one person can carry and install it, reducing roof load and labor time.
