Product Description

The Solax Solar Inverter 4000W X3-MIC-4.0K-G2 Three-phase is a 4 kW string inverter designed for low-voltage three-phase self-consumption installations that prioritize reliability, efficiency, and connectivity. With 2 independent MPPTs, IP66 protection rating, and a maximum efficiency of 98.3%, it ensures stable performance even in demanding environments. It allows oversizing up to 200% in the PV field and delivers 110% output overload, providing flexibility for projects with growth potential.

Main Features

2 MPPTs with a wide tracking range (120–980 V) and I_MPP 16 A per string (I_sc 20 A), suitable for high-power panels.
Maximum efficiency of 98.3% and Euro efficiency of 97.8% for higher energy yield.
IP66, Type II SPD on DC and AC, residual current detection, and AFCI (optional) for advanced safety.
200% PV oversizing and 110% output to cover production peaks.
Natural cooling, <30 dB, and compact design (342×434×144.5 mm; 15.5 kg).
Local and remote monitoring: USB/RS485/DRM and WiFi/LAN/4G option with SolaX Cloud.

Advantages or Benefits

More annual energy thanks to the wide MPPT range and leading 98.3% efficiency.
Fewer interruptions: IP66 and integrated protections (SPD on DC/AC, RCMU, thermal) increase robustness.
Agile installation: 2 MPPTs simplify unbalanced strings and mixed orientations.
Optimized cost: 200% oversizing avoids replacing the inverter when expanding panels.
Integrated export management to comply with regulations and adjust grid feed-in.

Purpose or Applications

Ideal for high-demand three-phase residential self-consumption, small businesses, offices, and SMEs. Suitable for rooftops with two orientations, installations with high-current modules, and projects requiring export control.
