- Delivery & return
Dual-MPPT with Flexible String Configuration — The inverter features 2 independent MPPT trackers, allowing separate PV strings (for different roof orientations or shading patterns), which helps optimize energy yield under real-world rooftop conditions.
High DC-Input & PV Compatibility — Supports a high maximum input voltage (up to 1,100 V DC) and high string current rating, making it compatible with modern high-voltage or high-wattage solar modules — giving flexibility in module selection and future-proofing.
High Conversion Efficiency — Offers a maximum DC-to-AC efficiency of ≈ 98.4%, ensuring a high conversion rate of solar energy to usable AC power, improving system yield and return on investment.
3-Phase Output & Smart / Grid-Ready Design — As a 3-phase inverter (400 V, 3L/N/PE), it’s suitable for homes or small commercial setups with 3-phase supply. It also supports modern grid-tie standards and offers optional safety features (e.g., arc-fault protection), making it a reliable inverter for long-term installations.
