With the growing demand for off-grid living and home emergency backup power, selecting an efficient, stable, and scalable inverter has become a key challenge for renewable energy enthusiasts and homeowners alike.
Today, we are introducing a standout product from AMPINVT: 6KW 48V to 120/240V Split Phase Inverter Charger Supports Up to 6 Units in Parallel. Notably, this is a professional-grade AC inverter-charger designed to excel at two core functions: efficiently converting 48V DC battery power into high-quality AC power, and rapidly recharging the battery bank when connected to grid power or a generator.
Key Highlights and Technical Features
1. 3-in-1 Integration: Inverter + AC Charger + Automatic Transfer Switch
This unit integrates a pure sine wave inverter, a high-power 80A smart AC charger, and an automatic AC transfer switch into a single device.
Pure Sine Wave Output: Features built-in AVR (Automatic Voltage Regulation) for stable power delivery.
80A Smart AC Charging: When connected to grid power or a generator, the built-in 80A multi-stage charging algorithm quickly and safely charges 48V battery packs while preventing overcharge.
Seamless Transfer: Automatically and seamlessly switches to battery power during grid outages, making it an excellent UPS backup solution for homes.
2. 6kW Continuous Power + Split-Phase Output (120V/240V)
Continuous Output: 6,000W (6kW)
Output Voltage: Supports 120V/240V split-phase output, perfectly matching both standard 120V household appliances and high-power devices requiring 240V.
3. Scalable Parallel Operation (Up to 6 Units / 36kW)
No need to replace existing equipment if your power needs grow in the future!
Supports parallel connection of up to 6 units, allowing the system capacity to scale from 6kW up to 36kW.
Supports single-phase, split-phase, and 208V three-phase modes, offering flexibility for residential, cabin, and even light industrial applications.
4. Broad 48V Battery Compatibility
Optimized for 48V battery systems, the unit supports almost all mainstream battery types on the market:
SLA / AGM / GEL / Li-ion battery & Customize. Support LiFePO4，Sealed Gel AGM Flooded Lithium Batteries.
Three Intelligent Operating Modes.
You can flexibly configure the inverter's power supply priority based on actual power conditions:
AC Priority Mode: Prioritizes utility power for the load and battery charging when grid power is available; rapidly switches to battery power during a grid outage, making it ideal as a UPS backup system.
Battery Priority Mode: Prioritizes the use of battery energy. Automatically switches back to utility/generator power and charges the battery when the battery voltage drops to a preset threshold; suitable for use with solar systems featuring external MPPT controllers.
ECO Mode: Automatically enters sleep mode when the load is below 10% to minimize no-load power consumption; quickly wakes up and resumes output when an increase in load is detected.
Smart Monitoring and Comprehensive Safety Protection
Wi-Fi Remote Monitoring: Paired with a Wi-Fi module and mobile app, the system allows for real-time status checks from anywhere and supports remote firmware upgrades to ensure continuous optimization.
Smart Temperature-Controlled Fan: Automatically adjusts fan speed based on internal temperature to maintain quiet operation, making it suitable for indoor or RV installations.
Comprehensive Protection: Features built-in battery high/low voltage alarms and protection, as well as safeguards against over-temperature, overload, and output short-circuits, ensuring safe and reliable long-term operation.
Use Cases and Configuration Recommendations
Home Power Backup / UPS System: Connects directly to the grid and a 48V battery pack; seamlessly takes over powering key household appliances during a blackout.
Generator Integration (Off-Grid Generator Backup): Ideal for off-grid cabins without grid access; starting the generator allows this device to rapidly recharge the battery while simultaneously powering the load.
Solar System Integration with Standalone MPPT: If you already own a standalone MPPT solar charge controller, this inverter-charger serves as the perfect companion for handling pure inversion and grid/generator-based recharging!
