120V80A High Power Inverter Bi-directional Switching UPS Automatic Switch Relay Voltage Converter
Description:
- 80A/120A is bidirectional switching, which means that the inverter priority and mains power priority can be switched freely to complete automatic switching. The inverter mains power selection switch is connected to a switch to select the mains power priority or inverter priority mode. Turning it on is the priority power supply mode for the mains, while turning it off is the priority power supply mode for the inverter. The two wires of the inverter switch need to be connected in series with your original inverter switch, so that if the mains suddenly loses power again, the inverter will quickly and automatically turn on for power supply, and it is also convenient to turn off the inverter power supply.
Mode Selection:
- Priority of mains power: Choosing mains power priority means that the mains power is the main source, and the inverter is in standby mode. When the mains power suddenly fails, the inverter is immediately started within 5ms. At this time, when the mains power suddenly comes in, it switches to mains power immediately, and the inverter is still in standby mode, ready for the next power outage.
- Inverter priority: Choosing inverter priority means that the inverter is the main power source and the mains power is used as a backup. When the battery discharges to the undervoltage value, the inverter stops working and immediately switches to the mains power state within 5ms. If the battery charges to a certain value and the inverter starts working, it will immediately switch to the inverter power supply state, and the mains power is still in the backup state.
Package Included:
- 1 x Inverter
