Description
Smart Off-Grid Inverter with Advanced Energy Management
Lithium Battery Activation via PV or Utility - Wakes up deeply discharged Li-ion batteries, preventing premature disposal.
Operates Without a Battery - Works grid-connected or directly from PV, lowering initial costs for budget-conscious off-grid installations.
Pure Sine Wave Output - Clean power for all loads (inductive/capacitive), including air conditioners, refrigerators, and motors.
Power Factor 1.0 - Delivers full rated power without derating, maximizing real load capacity.
Wide PV Input Range - 60Vdc - 500Vdc MPPT voltage, compatible with various solar panel configurations.
High-Current Built-in MPPT - Solar charge current up to 60A - 120A, with PV-to-inverter efficiency up to 96%.
Multiple Output Priority Modes - UTL, SOL, SBU, SUB - Flexible energy management for different usage scenarios.
Battery Equalisation (EQ) - Optimises battery bank performance and extends cycle life.
Detachable Dust Cover - Easy cleaning, ideal for harsh/dusty environments.
Optional WiFi Remote Monitoring - Real-time system status via smartphone or PC.
Key Technical Features
LiFePO₄ Communication via RS485 - Intelligent BMS interaction for safe and efficient charging/discharging.
Dual-Source Charging - PV + AC grid can deliver total charge current up to 60A - 120A (model dependent).
Wide AC Input Range - 90-280Vac, with selectable modes for personal computers (170-280V) or home appliances (90-280V).
Fast Transfer Time - 10ms (PC mode) or 20ms (appliance mode) between grid and battery.
Overload Protection - 10s at 110-140% load, 5s at ≥140% load.
Wide Operating Temperature - -10°C to +50°C, with 5-95% non-condensing humidity tolerance.
Built-in CC/CV Charging - 3-stage intelligent charge algorithm for both lead-acid and lithium batteries.
Main Functions
Automatic energy dispatch among PV, utility, and battery
Supports lead-acid and LiFePO₄ battery types
Solar charger + AC charger integrated; priority and current limits configurable
Surge power up to 2× rated power (e.g., 6.2kW model provides 12.4kVA surge)
Dual communication ports: RS232 + RS485 for monitoring and external control
