The RA Series Bidirectional Inverter is a cutting-edge power solution designed for seamless energy conversion between DC and AC systems. With models RA2000W and RA3000W, this inverter supports 12V to 220V bidirectional power flow, enabling efficient charging and discharging for a wide range of applications, from home energy storage to off-grid systems.
Up to 92% efficiency in inverter mode and ≥91% in charging mode.
Wide input voltage range:
AC Input: 180–264VAC, 47–63Hz.
DC Input: 10.5–16VDC (battery).
Pure sine wave output with ≤3% THD (resistive load), ensuring stable power for sensitive electronics.
Inverter Mode: Converts DC battery power to 220V AC (2000W/3000W rated, 4000W/6000W peak).
Charging Mode: Converts AC power to DC for battery charging (100A max current).
Bypass Function: Supports simultaneous charging and discharging (e.g., 1400W charge + 1800W bypass).
Comprehensive safeguards:
Overload, overvoltage, undervoltage, short-circuit, and reverse polarity protection.
Over-temperature control: Derates output at 95°C, shuts down at 105°C.
Robust design: Complies with IEC62388 and GB4943 safety standards.
LCD display with real-time monitoring (output power, battery level, fault alerts).
Customizable settings: Adjust charging parameters, output frequency (50Hz/60Hz), voltage, and battery type (lead-acid/LiFePO4/NCM).
Remote communication: Supports 485 or CAN protocols.
Iron casing with air cooling for optimal thermal management.
Compact dimensions: 241×345×121 mm (6.1KG).
Operating conditions:
Temperature: -10°C to +45°C.
Altitude: <3000m.
