Spare Power Supply Kit for Heating System 1200W + HAZE 12V 116Ah battery

Set Uninterruptible power supply unit (UPS or Inverter) heating system + Battery 12V 116Ah - 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. Alternative to a generator, voltage converter - inverter. Designed for a power of 1200W. When the voltage from the network disappears, it switches to operating mode in <0.01s. The inverter starts generating 230V AC pure sinusoid from any 12 Volt battery (max 200Ah). When voltage becomes available from the mains, the device charges the battery itself. The inverter operates fully automatically. If the consumption of the required device is 60-70W, then:
Using a 116Ah battery will run for up to 10 hours
