Overview
PowMr POW-RELAB 1.2KU is a hybrid solar inverter (low-frequency / power-frequency inverter) designed for residential and commercial energy storage systems. It converts 12Vdc battery power to 110Vac single-phase pure sine wave output, and includes a built-in 60A MPPT solar controller with a 15~105Vdc MPPT input voltage range.
Key Features
- Low-frequency inverter technology for stable pure sine wave output and support for motor-driven loads (e.g., air conditioners, refrigerators).
- Built-in MPPT solar charge controller: MPPT 60A; MPPT input voltage range 15~105Vdc.
-
Three operating modes for energy management:
- Grid priority (solar and battery as supplements)
- Solar priority (battery supplements; switches to grid when battery voltage is low)
- Solar + battery priority (battery powers load when no solar; switches to grid when battery voltage is low)
- ECO mode: shuts off inverter output when load is below 15W; checks load every 25 seconds.
- Safety protections: built-in AC output circuit breaker and battery circuit fuse; alarms and protections for overload, over-temperature, battery overvoltage/undervoltage, short circuit, and reverse connection protection; fault codes, buzzer alarms, and red LED fault indicator.
- BMS communication & dry contact: supports RS485/BMS communication for SOC protection and charge/discharge management; dry contact can control mains input switch based on battery voltage or solar status.
- High efficiency & low noise: inverter efficiency >98%; switching time <8 ms; operating noise <45 dB.
- Overload handling information provided: 105%–150% load (11 seconds); 150%–200% load (2 seconds); >200% load (400 ms).
- Protection list also provided: short circuit protection, over-load protection, over current protection, backfill protection, over voltage protection, over-temperature protection, under voltage protection, over charge protection.
- Compatible battery chemistries listed: SEL, GEL, FLD, AGM, LiCoMnNiO2, LiFePO4.
