Solar Inverters

FoxESS 20kW 3Ph 2MPPT (T20-G3 (AS4777-2 2020))

The FoxESS T20-G3 is a three-phase, 20 kW grid-tie PV inverter designed for medium-to-large residential or small commercial solar systems. It features dual MPPT inputs, wide DC input range (up to 1100 V), high efficiency (~98.6%), and weather-resistant IP65 enclosure — making it suitable for outdoor installations and high-power solar setups.

High Power Output & Three-Phase Support

  • Rated AC output: 20 kW (3-phase) — enough for large households, commercial-use, or heavy loads.
  • Supports standard 3-phase grid connection (3/N/PE) — useful where three-phase supply is available or required.

Dual MPPT & Wide DC Input Range for Flexibility

  • Has 2 independent MPPT trackers — allowing optimization of two separate PV strings (good if panels have different orientations or partial shading).
  • DC input specs: up to 1100 V max DC voltage, nominal operating ~ 600 V. MPPT voltage range wide (e.g. 140 – 1000 V).
  • Allows oversizing PV array (within limits), giving flexibility in PV configuration and maximizing generation during low-sunlight hours.

High Efficiency & Reliable Conversion

  • Maximum inverter efficiency rated at ≈ 98.6%, ensuring minimal losses in DC → AC conversion.
  • MPPT efficiency is high (spec sheet indicates ~ 99.8% MPPT tracking efficiency for FoxESS inverters), aiding better energy harvesting.

Durable, Outdoor-Ready Build & Ease of Installation

  • Enclosure rated IP65 — weatherproof, dust-tight and suitable for outdoor or semi-outdoor installation.
  • Designed for “plug-and-play” installation and relatively compact size for its power class — facilitating easier mounting and integration.
  • Supports remote monitoring (via web/app) — useful for managing and tracking system performance in real time.

Strong DC Input Capacity & Suitable for Large Solar Arrays

  • Max. recommended DC input power: ≈ 30,000 W (30 kW DC) — allowing a PV array somewhat larger than AC rating if needed.
  • Supports high DC input current (Input A & B each up to 28 A) which helps support large string configurations or multiple strings per MPPT.
  • Rating (kW) : 20,000 W (20 kW)
  • MPPT : 2
  • Rating (kW) : 30,000 W (30 kW DC)
  • IP Rating : IP65
  • Weight (kg) : 20–21 kg
  • Dimension (W/D/H) : 370*183.5*480
  • Product Warranty (Years) : 10-year standard product warranty
