Set: 400W Backup power supply for heating 400W + Battery 12V 30Ah

• An Uninterruptible Power Supply (UPS or Inverter) is essential for every boiler and system. It protects the boiler's automation and the circulation pump from voltage fluctuations that can damage the electronics, and maintains the operation of the heating system if the electricity goes out.
• Kit components:
• 12V 30Ah sealed maintenance-free battery.
• The battery switches to working mode <0.01s if the voltage in the network is lost.
• The 400W 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 operating status of the device.
• The device has wall mounts to save space.
• With a 30Ah battery and 60-70W consumption, the heating system will work for up to 3 hours.
