10000W Low-Frequency Inverter Charger (QSP Series)
Models QBT10000-248 / QBT10000-148 — integrates inverter, automatic charging and AC/battery automatic transfer in one unit, with power frequency scheme plus electrical isolation technology for strong load and surge capability.
Key Features
- Integrates inverter, automatic charging and AC/battery automatic transfer.
- Power frequency scheme with electrical isolation technology — strong load capacity and strong surge resistance.
- Pure sine wave output with stable frequency and voltage, low ripple.
- Smart 4-stage charging with adjustable charging voltage and current.
- Ultra-low static power consumption effectively saves battery energy.
- Multiple protections: AC and DC input high/low voltage, overload, temperature and output short circuit.
- Battery activation charging mode protects deeply discharged batteries during charging.
- Built-in two independent chargers (mains and solar MPPT) for starting battery and backup battery (custom version).
- Built-in AC bypass relay (< 800 ms).
- Extra-wide AC input voltage (80–140VAC / 165–265VAC).
- Generator automatic energy distribution technology makes full use of generator power and reduces configuration (custom version).
- Battery over-temperature protection (optional).
- Single-wire on/off: inverter can be switched on/off with any positive supply signal above 5V (optional).
- Personalized system settings via the matching LCD control panel (optional) or communication software.
- Mains auto-start (optional), inverter-priority mode (optional), -40°C cold start (custom).
