ONE DEVICE. Inverter. Charger. UPS. All Built In. Most inverters do one thing. This does three – simultaneously. Convert battery power to 220V AC, charge your battery bank from the grid, and switch between grid and battery power in less than 12 milliseconds when the grid goes down. Your appliances never even notice. FUNCTION 01Pure Sine Wave InverterConverts your 12V or 24V battery bank to clean 220V-230V AC power. 4,000W peak, 2,000W continuous. Pure sine wave safe for all sensitive electronics. 95% efficiency. FUNCTION 02Built-In Battery ChargerWhen grid power is available, the built-in 20A charger automatically replenishes your battery bank. Charger input: 220V-230V. Working voltage range: 170V-250V. Max charge current: 20A. FUNCTION 03UPS - Uninterruptible PowerWhen grid power fails, this unit switches to battery power in less than 12ms - fast enough that most appliances and computers do not register the interruption. True UPS protection. THE UPS ADVANTAGE Less than 12ms. Your Appliances Never Know the Grid Went Down. A standard inverter has no grid connection. When grid power fails, you manually switch over – and everything connected resets. Computers shut down, data is lost, processes are interrupted.This unit stays connected to the grid. When the grid fails, it switches to battery power in under 12 milliseconds – fast enough that computers, routers, CCTV systems, and sensitive electronics experience no interruption. This is true UPS protection for homes, home offices, and small businesses.When grid power returns, the unit switches back automatically and begins recharging your battery bank via the built-in 20A charger. Read our inverter troubleshooting guide for installation tips. IDEAL APPLICATIONS Where This Inverter Charger Excels. Home Backup PowerProtect your home from power outages. Grid-connected charging keeps your battery ready. Less than 12ms UPS switch means your fridge, router, and essentials never go off. Home Office and Small BusinessKeep computers, CCTV, routers, and POS systems running through outages. Data is safe. Operations continue. The 12ms transfer is below the threshold most computers detect. Caravan and MotorhomeOn hook-up at a site: charger tops up your battery. Off-grid: inverter runs your 220V appliances. One unit handles both modes automatically. Solar Off-Grid SystemPair with a LiFePO4 battery bank and MPPT controller. The built-in charger handles grid top-up when solar is insufficient.

What is the difference between this and a standard inverter?A standard inverter only converts battery power to AC. This unit also includes a built-in 20A battery charger and a UPS function. When grid power is available, the charger keeps your battery topped up. When grid power fails, the unit switches to battery in under 12ms – no interruption to your appliances.Will my computer survive the switch from grid to battery?Yes. The less than 12ms transfer time is below the hold-up time of most computer power supplies, which is typically 16-20ms. Computers, routers, and most electronics will not register the switch. This is the key advantage over a standard inverter.What battery type and size do I need?Compatible with lead-acid, AGM, and LiFePO4 batteries in 12V or 24V configuration. For backup power, a 12V 100Ah LiFePO4 battery gives approximately 40-60 minutes runtime at 2,000W continuous load. Browse our LiFePO4 battery range.Can I use this without a battery – as a pure charger?The charger function requires a battery connected. It charges the battery from grid power. The inverter then draws from that battery to produce AC output. Both functions require a battery bank to operate.Need a 110V version or a higher power rating?This model outputs 220V-230V only at 4,000W peak.
