Set: Professional Inverter UPS for heating system 1000W + 12V 120Ah 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 sealed, maintenance-free battery.
The battery switches to operating mode in <0.01s if the network voltage is lost.
The 1000W Inverter produces stable 230V AC from any 12V battery (up to 200Ah).
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 120Ah battery and 60-70W consumption, the heating system will operate for up to 12 hours.
