Backup Power Supply Kit for Heating System UPS 700W + 12V 100Ah battery

An uninterruptible power supply (UPS or Inverter) is essential for every boiler and heating system. It protects the boiler's automation and circulation pump from voltage fluctuations that can damage the electronics, and keeps the heating system running if the power goes out.
Kit ingredients:
12V 42Ah sealed, maintenance-free battery.
The battery switches to operating mode in <0.01s if the network voltage is lost.
The 700W Inverter produces stable 230V AC from any 12V battery (up to 120Ah).
When the mains voltage is restored, the device automatically charges the battery.
A clear LCD display shows the device's operating status.
The device has wall mounts to save space.
With a 42Ah battery and 60-70W consumption, the heating system will operate for up to 4 hours.
