Overview
The Ampinvt 1200W off-grid low frequency solar inverter converts 12Vdc battery power to 120Vac output and can charge a battery bank when AC power and/or solar power is connected. It features a pure sine wave inverter with a built-in 40A MPPT charge controller (30A/40A series) and supports multiple working modes for flexible operation.

Working Modes
- AC/Line priority mode -- Always uses AC power as priority input, provides AC output, and automatically charges the battery.
- Battery priority mode -- Priority is given to battery power supply. After low voltage protection, it transfers to AC grid power supply. When the battery is full, it transfers back to battery power.
- ECO Mode -- Load < 10%: automatic sleep and stops output; load > 10%: automatically boots back to normal inversion.
- Generator mode -- A generator connected to the AC input; output is stabilized through AVR while the battery is recharged.
- Unattended Mode -- When battery voltage is low, the inverter enters standby (power saving). When battery voltage returns to the user-set value (such as via solar charging), it restores normal output for fully automatic operation.

Attention / Installation Notes
- This solar inverter is able to charge the battery bank when AC power/Solar power is connected to the inverter.
- This inverter can ONLY work with a 12V battery system.
- Inverter CAN NOT support connect in parallel.
- Inverter MUST have a battery, and the battery MUST be connected first.
