Overview
The Ampinvt 1200W DC 24V pure sine wave power inverter with charger is an off-grid inverter charger designed for a 24V battery system and 120VAC AC output. It supports UPS-style backup by switching between AC input and battery power, and it can charge the battery bank when AC power is connected.
Key Features
- Pure sine wave output (low frequency design)
- Continuous output power: 1200W; peak power: 3600W
- Battery system: 24V only (not for 12V/48V systems)
- AC output: 120VAC
- Built-in AC charger: automatic 15A; adjustable charging current: 0–15A
- Automatic AC mains switcher
- Transfer efficiency: above 88%
- Built-in toroidal transformer (strong overload and impact resistance)
- Battery temperature sensor protection
- Interface & controls: LCD display, LED indicators, function keys
- Terminals/ports (labeled): AC input, AC output, battery positive (BAT+), battery negative (BAT-), AC fuse, remote control port
- Parallel operation: not supported (cannot connect in parallel)
- Connection order: battery must be connected first
Five Working Modes
- AC Priority Mode – AC input (utility power/city grid) supplies the AC output (appliances/load) first and charges the battery at the same time. Charging stops automatically when the battery is fully charged. If AC input is unavailable, it switches to battery power supply.
- Battery Priority Mode – Battery supplies the AC output (appliances/load). When battery voltage reaches the low-voltage limit, it switches to AC input supply if AC input is available; otherwise it shuts down. When battery voltage returns to the restore setting, it switches back to battery supply.
- ECO Mode – Similar to AC priority mode. When AC input is off, it enters standby when the appliance load is under 5% of inverter capacity. It cycles between on and standby to detect when the load exceeds 5%, then returns to inverting status.
- Generator Mode – For generator input; connects generator power to the inverter AC input through the inverter AVR regulator, automatically matches 50Hz/60Hz frequency, and regulates output voltage within the normal operating range.
- Unattended Mode – Similar to AC priority mode. When AC input is off and battery voltage is too low, it shuts down AC output and enters standby. Once the battery is charged back to the restore voltage point, it restarts AC output. When AC input returns, it also restarts AC output.
