Solar Inverters

Solax 5kW 1Ph 3MPPT G2 (X1-SMT-5K-G2 (AS4777-2 2020))

The SolaX X1-SMT-5K-G2 is a 5 kW (AC) single-phase grid-tie string inverter suitable for residential rooftop solar PV systems. Equipped with three MPPT trackers, support for PV oversizing, and a rugged IP66-rated enclosure, it’s designed for flexibility in panel layout, reliable solar-to-AC conversion, and weather-resistant installation — a good match for small to mid-size solar plants.

  • Product Code:23784
  • Model No.:X1-SMT-5K-G2 (AS4777-2 2020)

High PV-Input Flexibility & Oversizing Support — Supports up to 200% PV oversizing (i.e. PV array capacity significantly higher than inverter rating) and a wide MPPT operating voltage range (40–560 V), making it compatible with high-wattage/high-voltage solar modules and maximizing generation potential.

Three MPPTs for Flexible Panel Orientations — With 3 independent MPPT trackers (strings per MPPT: 1/1/1), the inverter allows multiple panel strings, ideal when panels are placed on different roof slopes or orientations — maximizing yield under varied roof geometries and partial shading.

Smart Features, Safety & Monitoring Capabilities — Built-in protections (Type II SPD on AC & DC sides, anti-islanding, over/under voltage, residual-current detection, DC isolation, reverse-polarity protection etc.), optional rapid-shutdown and AFCI support, plus a plug-and-play communications terminal (RS485 / CT / meter / optional WiFi / LAN / 4G) with fast data-refresh (10 s) and I-V curve diagnosis — enabling smart monitoring, remote data, and safe grid-tie operation.

Weather-Resistant & Outdoor-Ready Design — With an IP66 ingress protection rating and natural/fan-less cooling, the inverter is suitable for outdoor rooftop installation — protecting against dust, rain and heat.
