Product Description

The Solax X1-BOOST-4.2K-G4 4200W is a single-phase grid-tied inverter for homes that require a bit more power without sacrificing the flexibility of the BOOST series. With 2 true MPPT, a wide MPPT range (40–560 V), and a maximum input voltage of 600 V, it optimizes production on rooftops with two different orientations or inclinations. Its 98% efficiency, IP66 enclosure, and convection cooling ensure reliability, low noise, and minimal outdoor maintenance. Additionally, it supports PV array oversizing up to 200% to increase annual energy production.

Main Features

Nominal AC power: 4200 W; maximum apparent power: 4620 VA.
2 MPPT / 1 string per MPPT; maximum input current 18.3 A per MPPT (Isc 22 A).
MPPT range 40–560 V; startup voltage 50 V; max PV voltage 600 V.
Maximum efficiency 98%; European efficiency 97%; night consumption < 3 W.
IP66, −25 °C to +60 °C, noise < 25 dB, convection cooling.

Advantages or Benefits

Higher production with 200% PV oversizing (≈ 8 kWp DC) and global MPP scanning.
Versatility for two slopes (east/west), partial shading, or different inclinations without loss of performance.
Safety with anti-islanding, grid monitoring, thermal protection, and compatibility with SPD Type II on DC/AC, AFCI, and RSD (optional).
Advanced energy management via meter/CT for zero export and data updates every 10 s (with new Pocket).
Connectivity SolaX Cloud via Pocket WiFi/LAN/4G and multi-device management with DataHub and master/slave modes via Modbus.

Purpose or Applications

Recommended for homes with 10–12 panels, pergolas, and medium-sized residential roofs that require export control, robustness, and high performance with two independent strings.
