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

Uninterruptible power supply (UPS or Inverter) for the heating system - necessary for any heating system, as it protects the boiler's automation and circulation pump from voltage surges that cause damage to the electronics, and also ensures the operation of the heating system in the event of a power outage.
When the mains voltage disappears, it switches to operating mode in <0.01s. The UPS Inverter starts generating 230V AC pure sine wave from the built-in 12 Volt batteries. When the voltage becomes available again from the mains, the device charges the batteries fully.
The inverter has a convenient LCD display that shows a visualization of the current operating status.
Designed for 900W power.
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 PC program. The external module UPS-SNMP-EXT sold separately.
