Professional Heating system pure sine wave UPS Inverter with battery 2x12V / 9Ah, 900W, LCD display

Uninterruptible power supply (UPS or Inverter) for heating system - necessary for any heating system, as it protects the boiler automation and circulation pump from voltage surges that cause damage to electronics, as well as ensures the operation of the heating system in the event of a power outage.
When the voltage from the network disappears, it switches to lt;0.01s during the operating mode. The UPS Inverter starts generating 230V AC pure sinusoid from built-in 12 Volt batteries. When the voltage becomes available from the mains again, the device charges the batteries completely.
The inverter has a convenient LCD display, which shows the visualization of the current operating status.
Designed for power 900W.
If the circulation pump consumption is 60-70W, then using 2x12V/9Ah batteries, the system will operate for up to 2 hours.
The device can be connected to the Internet using an external module (UPS-SNMP-EXT sold separately) and controlled with a free computer program. External module UPS-SNMP-EXT sold separately.
