- Delivery & return
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.
