Product Description

The Solax Solar Inverter 20000W X3-PRO-20.0K-G2 Three-phase elevates the PRO G2 series to 20 kW continuous for high-consumption commercial and residential applications. Its dual high-current MPPT tracker, IP66 protection, and ~98.3% efficiency ensure more usable energy and reliable outdoor operation. Designed for next-generation modules, it accepts 32 A per MPPT (Isc 40 A per input), allowing strings with high-amperage TOPCon/HJT panels. The platform supports 150% DC oversizing and 110% output, so it can handle irradiance peaks and allows PV field expansion without replacing the inverter.

Main Features

2 MPPTs with wide tracking range (~160–980 V) and reduced start-up voltage (~200 V).
32 A per MPPT (up to 2 strings per tracker) and I_sc 40 A per input.
Maximum efficiency ~98.3% (Euro ~97.7%) and adjustable PF 0.8 ind…0.8 cap.
IP66 rating, SPD Type II on DC/AC, RCMU and anti-islanding; optional AFCI for arc mitigation.
150% PV oversizing and 110% output overload for peaks and expansions.
USB/RS485/DRM communication and WiFi/LAN/4G options with SolaX Cloud for advanced O&M.

Advantages or Benefits

Higher annual production thanks to the wide MPPT range and high current per tracker.
Industrial safety with IP66 and SPD on DC/AC, reducing downtime due to electrical events.
Total flexibility on the roof: two orientations, partial shading, or unbalanced strings.
Scalability: 150% DC + 110% AC = generator growth without changing the inverter.
Remote telemetry and maintenance to minimize operating costs.

Purpose or Applications

Aimed at SMEs, businesses, schools, energy communities, and homes with high three-phase consumption. Excellent when export limits, continuous monitoring, and compatibility with high-power modules are required.
