Spare Power Supply Kit for Heating System 1600W + 12V 100Ah battery

Set Uninterruptible power supply unit (UPS or Inverter) heating system + Battery 12V 100Ah- 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 the generator, voltage converter - inverter. Designed to power 300W.Pazūdot voltage from the network, switches to lt;0.01s during operation. 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 works completely automatically. If the consumption of the required device is 60-70W, then:
Using 100Ah the battery will work up to 10 hours
Using 100h the battery will work up to 10-12 hours
