In both cases I used a deep cycle marine battery feeding an inverter and disconnected the normal 120 vac feed to the boiler and tied into the 120 vac coming from the inverter. I then charge the battery with a small 1200 watt generator every 24 hours. I think the inverter uses a lot of power just to make the 120 vac. The 120 vac boiler feed is only used to power a 120/24 VAC transformer that is needed to open the solenoid valve on the natural gas line and open the zone valves. I would rather use a 12 battery and convert directly to 24 vac and bypass the 120/24 vac transformer and eliminate the 12/120 inverter. Is there a simple way to convert the 12 vdc to 24 vac so that I can eliminate the inverter?
