Grid-Tied + Off-Grid Flexibility:
Operates in grid-tied mode (exporting excess solar to the grid) and switches to off-grid battery backup in <8ms during outages. Powers critical loads (HVAC, refrigerators, home offices) using 24V/48V batteries (3kWh–20kWh storage supported).
Smart Battery Management:
Features a 100A adaptive charger with customizable profiles for LiFePO4, lead-acid, or lithium-ion batteries. Extends battery life to 6,000+ cycles (15+ years for LiFePO4) by preventing overcharging/discharging.
Pure Sine Wave Output:
Generates clean 230V AC power (pure sine wave) to protect sensitive electronics (laptops, medical devices) and ensure compatibility with all household appliances.
Remote Monitoring via WIFI/Bluetooth:
Connects to a mobile app for real-time tracking of solar production, battery SOC, grid usage, and system health. Set custom schedules (e.g., charge batteries during off-peak grid hours) to minimize utility costs.
Rugged Outdoor Design:
IP65-rated enclosure withstands dust, rain, and extreme temperatures (-25°C to 60°C). Reinforced casing suitable for outdoor installation near solar panels in harsh climates (coastal areas, deserts, or cold regions).
