300W, Pure Sine Wave Inverter - UPS, Backup Electricity for Heating Systems, Lithium, AGM, GEL battery.

A backup power supply unit (UPS or Inverter) ensures uninterrupted operation of the heating system in the event of a power outage. The Inverter also protects the boiler automation and circulation pump from voltage surges that can cause damage to the electronics. When the voltage in the network disappears, the Inverter switches to operating mode in less than 0.004 seconds and starts generating 220V alternating current with a pure sinusoid, using the 12V battery. When the voltage in the network is restored, the device starts charging the battery, and then the Inverter automatically returns to standby mode. The Inverter has an LCD display. The Automatic Voltage Regulation (AVR) function stabilizes the input voltage. Intelligent battery management that guarantees long-term battery operation. The Inverter operates completely automatically. If the consumption of the required device is 60-70W, then: 30Ah battery, it will work up to 3 hours
:: using 100Ah battery, it will work up to 10 hours.
