Spare Power Supply Kit for Heating System 500W + 12V 100Ah battery

Set Uninterruptible power supply unit (UPS or Inverter) heating system + Battery 12V 90Ah - 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 500W. 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 works fully automatically. If the consumption of the required device is 60-70W, then: Using a 20Ah battery will work up to 2 hours Using a 100Ah battery will work up to 10-12 hours
