Spare Power Supply Kit for Heating System 300W + 12V 20Ah battery

Uninterruptible power supply (UPS or Inverter) heating system - necessary for any heating boiler and 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 cases of power outages. The kit includes a 12V 20Ah battery. The battery is sealed, so it does not require maintenance. When the voltage from the network disappears, the inverter immediately switches to operating mode and starts generating 230V AC pure sinusoid from any 12 Volt battery (max 120Ah). When voltage becomes available from the mains, the device charges the battery itself. The inverter has LED light indicators. If the heating system consumption is 60-70W, then using the 20Ah battery, the system operating time will be up to 2 hours.
