Optimal Power Output: Delivers 3.6kW continuous AC power (surge capacity up to 7.2kW for 5 seconds) to handle household essentials like refrigerators, TVs, and small HVAC units, with single-phase 220V output for easy integration into residential electrical systems.
High-Efficiency MPPT: Equipped with a single MPPT tracker (max DC input voltage 500V) that boosts solar energy harvest by up to 28% in low light or partial shading. MPPT efficiency reaches 99.0%, ensuring maximum power extraction from 6-8 solar panels (typically 300-450W each).
Hybrid Versatility: Seamlessly switches between grid-tied (export excess solar to the grid), off-grid (run on solar + batteries), and backup modes (auto-switch to batteries during outages in <20ms), preventing disruptions to critical devices.
Battery Compatibility: Works with 48V lithium-ion (LiFePO4, Li-ion) and lead-acid batteries (up to 200Ah), supporting battery charging/discharging management to extend lifespan-configurable via app to prioritize solar charging over grid.
WIFI-Enabled Smart Monitoring: Built-in WIFI connects to a mobile app and cloud platform, providing real-time insights into solar production (kWh/day), battery state of charge (SOC), grid usage, and system alerts. Users can remotely adjust settings like discharge depth or schedule charging during off-peak grid hours.
Grid-Friendly Operation: Supports net metering (where allowed) to sell surplus solar energy back to the grid, with adjustable export limits to comply with local utility rules. Automatically prioritizes solar power for home use, reducing reliance on grid electricity.
Robust Safety & Durability: IP65-rated enclosure resists dust and rain, suitable for outdoor installation. Includes protections against overvoltage, overcurrent, short circuits, reverse polarity, overheating, and battery over-discharge. Certified to IEC 62109 and VDE standards for reliable performance.
