Set Uninterruptible power supply unit (Inverter) for heating system 600W + 12V 120Ah 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 the event of a power outage. The kit includes a 12V 120Ah battery. The battery is sealed, so it does not require maintenance. When the voltage from the network disappears, it switches to lt;0.01s operating mode. 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 has LED indicators, a sound signal at the moment of voltage loss, input signal stabilization with AVR, short circuit and overvoltage protection. If the heating system consumption is 60-70W, then using the 120Ah battery, the system operating time will be up to 12 hours.
