Dual MPPT Trackers (99.9% Efficiency): Equipped with 2 independent MPPT trackers to optimize energy harvest from 2 separate PV strings. Adapts to partial shading, mixed orientations, or varying sunlight, boosting daily solar yield by 8–12% compared to single-MPPT models.
Seamless Grid-Tied + Off-Grid Flexibility: Operates in grid-tied mode (exports excess solar to the grid for net metering) and switches to battery backup in <10ms during outages, ensuring uninterrupted power for critical loads (refrigerators, medical devices, HVAC systems).
Broad Battery Compatibility: Works with 48V LiFePO4, lead-acid, and lithium-ion batteries (supports 2kWh–15kWh storage). Features a 120A smart charger with customizable profiles to extend battery life to 6,000+ cycles (15+ years for LiFePO4).
Pure Sine Wave Output: Generates clean 230V AC power (pure sine wave) to protect sensitive electronics (laptops, smart home devices) and ensure compatibility with all household appliances, from microwaves to air conditioners.
Smart Energy Management (Wi-Fi Enabled): Built-in Wi-Fi allows remote monitoring via a mobile app-track solar production, battery SOC, MPPT performance, and grid usage in real time. Set custom charging/discharging schedules to align with time-of-use tariffs, cutting utility costs by 30–40%.
Compact & Durable Design: IP65-rated enclosure resists dust, rain, and extreme temperatures (-30°C to 60°C), suitable for indoor/outdoor installation. Compact size (≈40cm×30cm×18cm) fits easily in utility rooms or garages.
