Solax 3kW 1Ph 2MPPT G4 (X1-BOOST-3K-G4 (AS4777-2 2020))
The SolaX X1-BOOST-3K-G4 is a compact, single-phase 3 kW grid-tie string inverter designed for residential rooftop solar PV systems. It features dual MPPT, supports DC-input oversizing (up to 200 %), wide MPPT voltage range, and comes with IP66-rated weather-resistant housing for indoor or outdoor installation. It’s suited for small-to-medium PV arrays and provides efficient, reliable DC → AC conversion
- Product Code:20089
- Model No.:X1-BOOST-3K-G4 (AS4777-2 2020)
Dual MPPT for Flexible Panel Layouts: The inverter offers 2 independent MPPT trackers, enabling two separate solar-panel strings (e.g. on different roof faces or tilts). This flexibility helps maximize energy yield in varied roof geometries or partially shaded conditions.
High PV-Input Flexibility: 200 % DC Oversizing & Low Startup Voltage: Supports 200% oversizing of PV input relative to AC output and accepts up to 600 V DC (Voc). Its low startup voltage (~50 V) allows earlier generation — useful when using high-efficiency modern solar modules or when sunlight is weak.
High Efficiency & Wide MPPT Operating Range: Offers up to ≈ 98% maximum conversion efficiency, with MPPT operating voltage range from 40 V to 560 V, allowing compatibility with a broad variety of solar module types.
Smart Monitoring & Modern Safety / Grid-Tie Features: Supports Wi-Fi (via optional dongle), remote monitoring via SolaX Cloud (data refresh ~ 10 s), built-in export-control, and optional safety protections including AC/DC Type II SPD, optional rapid shutdown (RSD), and optional AFCI (arc-fault) — making it modern, safe and grid-compliant.
