Overview
The Ampinvt 800W DC 12V pure sine wave power inverter with charger is designed for 12V battery systems and provides UPS-style backup switching between AC input and battery power. It can charge the battery bank when AC power is connected, and supports multiple operating modes for different power-source priorities.
Key Features
- Pure sine wave inverter with charger: Charges the battery bank when AC power is connected.
- 12V battery system only: This inverter can ONLY work with a 12V battery system.
- Output power: 800W continuous output power; 2400W peak power.
- Not parallel-capable: The inverter CAN NOT connect in parallel.
- Connection requirement: Battery MUST BE connected first.
- Controls & indicators: LCD display, LED indicators, and function keys.
- Interfaces & protection access: AC input, AC output, battery positive/negative terminals, remote control port, and AC fuse.
Working Modes
- AC Priority Mode - The AC input (utility power/city grid) will supply power to AC output (appliances/load) first, and auto charge battery at the same time. Inverter will auto stop charging when battery has been fully charged. When there is no AC input, inverter will auto switch to battery power supply.
- Battery Priority Mode - The battery power will supply power to AC output (appliances/load). When battery voltage reaches the low voltage limit, if AC input is on, inverter will auto switch to AC input supply; if AC input is off, inverter will auto shut down. When battery voltage reaches the low voltage restore setting, inverter will auto switch back to battery supply.
- ECO Mode - Similar to AC priority mode. When AC input (utility power/city grid) is off, the inverter will auto enter standby status when appliances capacity is under 5% of inverter capacity. The inverter will keep auto switching between on and standby status to detect if AC output (appliances/load) capacity is over 5% of the inverter capacity. If AC output capacity is over this limit, the inverter will auto switch from standby status to inverting status.
- Generator Mode - Uses an unstable generator to generate power, accesses the inverter AC input through the inverter AVR regulator, automatically matches 50Hz/60Hz municipal frequency, and regulates output voltage in the normal operating range.
- Unattended Mode - Similar to AC priority mode. When AC input (utility power/city grid) is off or battery voltage is too low, the inverter will auto shut down AC output and enter STANDBY status. Once battery has been charged back to the restore voltage point, the inverter will restart the AC output. When AC input returns, inverter will auto restart AC output as well.

Details

Pure sine wave output with built-in charging support for 12V battery systems, ideal for UPS-style backup switching.

Clear, labeled connections and an LCD control panel make setup and monitoring straightforward for AC input, loads, and battery wiring.

Pairs well with a 12V battery bank to keep essential loads running when utility power is unavailable.

Connect AC input and your load to the terminal block, then wire the battery bank to the positive and negative DC terminals (battery first).
