Captain Stick Posted February 2, 2017 Report Share Posted February 2, 2017 My camper is permanently set up on my lot. I'm set up on AC power. My converter has recently played out. I won't to know if there are any options I have to get rid of my battery/converter set up? I still need 12v for interior lights, thermostat, and water heater ignition. I know that replacing the converter and simply running it without batteries will burn up a new converter. Does anyone have any suggestions on how to run my 12v DC things without using batteries?

dartmouth01 Posted February 2, 2017 Report Share Posted February 2, 2017 I think something like this should work...... https://www.amazon.com/Powermax-Supply-Converter-Charger-Pm3-75/dp/B00F8MC43Q Link to comment Share on other sites More sharing options...
Captain Stick Posted February 2, 2017 Author Report Share Posted February 2, 2017 Thanks to both. Will both these options work without maintaining batteries? Link to comment Share on other sites More sharing options...
Devilishjim Posted February 2, 2017 Report Share Posted February 2, 2017 Your furnace blower also runs on 12V, I think it would probably be best to stay with factory setup on batteries because there is a constant demand for 12v. You could probably get by with only one battery depending on how much the furnace would use. Link to comment Share on other sites More sharing options...
Dutch_12078 Posted February 3, 2017 Report Share Posted February 3, 2017 Most current converters will work fine without a battery connected, but having one gives you the capability handling short term loads that exceed the capacity of the converter. In your situation, a single battery should be adequate. Link to comment Share on other sites More sharing options...
Mark and Dale Bruss Posted February 3, 2017 Report Share Posted February 3, 2017 Don't know about a converter with no batteries. The batteries are the voltage reference the converter works against. Link to comment Share on other sites More sharing options...
chirakawa Posted February 3, 2017 Report Share Posted February 3, 2017 I always thought that the battery served as a filter for the sensitive electronics contained within the circuit boards of the various 12 volt appliances like water heater, furnace, fridge, etc. I'm not an electronics person, just thought I had read that more than once.

mptjelgin Posted February 3, 2017 Report Share Posted February 3, 2017 There are 12V power supplies for many different uses that do not rely on a battery for reference voltage. I fly RC planes and most large chargers require a separate 12V power supply. Converted server power supplies are very popular and affordable. Lipo Connection Solutions is one company I am familiar with that has provided thousands of these converted server supplies to folks needing 12V DC power from a 120V AC circuit. Here is a link to converted HP server power supply that will supply up to 60 amps of 12V power. They also have converted Dell supplies for slightly more. I would think that 60 amps would be plenty for powering a typical array of RV lights, fridge, furnace, etc. http://lipoconnectionsolutions.com/HP-12v-750w-Power-Supply-Bare-Wire-Leads-12750BL.htm Link to comment Share on other sites More sharing options...
kb0zke Posted February 3, 2017 Report Share Posted February 3, 2017 I'd keep the batteries in the circuit. In addition to buffering the load on the converter, they also will keep you going when the electricity goes out. Don't know where you are, but there are few places that haven't had a power outage sometime. The batteries won't keep your a/c going, but they will keep the furnace going. If you have an inverter your microwave will also work. Link to comment Share on other sites More sharing options...

In your situation, a single battery should be adequate. I haven't looked all relevant converters up, but here's what the WFCO FAQ says about it: "Does the converter need a battery to operate?" "No. The battery works in conjunction with the converter to supply DC power to the RV. A battery is typically only necessary if you do a lot of dry camping or have slide-outs and/or a leveling system." Link to comment Share on other sites More sharing options...

Absolutely true, but it is important to remember that all of the propane powered appliances require 12V-dc for the controls so if you keep your battery it means that should you loose 120V-ac power, those appliances will still work just fine until it returns, but if you should loose 120V and not have the batteries, then you have no heat, hot water, refrigerator, or lights.

frater jason Posted February 6, 2017 Report Share Posted February 6, 2017 I'm set up on AC power. My converter has recently played out. I won't to know if there are any options I have to get rid of my battery/converter set up? Is there some reason you want to get rid of the batteries? I'm with the others who have recommended leaving them in place. Link to comment Share on other sites More sharing options...
Captain Stick Posted February 6, 2017 Author Report Share Posted February 6, 2017 I want to get rid of the batteries because I'm honestly tired of buying them every couple years and not really needing them. I've considered going as far as gutting the walls to run 120 light fixtures and switching to a central air unit. I can also switch to an electric water heater. My fridge and microwave are electric only. I live 30 minutes away from my lot so in the event of a long term outage, I'd just go home. Link to comment Share on other sites More sharing options...
dartmouth01 Posted February 6, 2017 Report Share Posted February 6, 2017 Strange that you'd be losing your batts in a couple years, I've had Walmart DC batts go for 4 years and probably could go longer if I hadn't switched over to 6V GC batts. And that is with heavy use..... Link to comment Share on other sites More sharing options...
mptjelgin Posted February 6, 2017 Report Share Posted February 6, 2017 I agree with your position. Get rid of them. In your situation there is no reason to have them, as a power outage will have no more impact on you than it would in someone living in a sticks and bricks house. As I mentioned above there are numerous 120V AC to 12V DC power supplies on the market that don't need a battery in the circuit. Link to comment Share on other sites More sharing options...

And that is with heavy use..... Many of the less sophisticated converters hold the voltage too high and over a period of months or a couple of years will kill batteries if they are not carefully monitored for water. The fact that you use yours heavily makes me think that you probably have a 3-4 stage charger and monitor them. If someone is plugged in all of the time they may never think about their batteries until they're cooked. Link to comment Share on other sites More sharing options...
dartmouth01 Posted February 6, 2017 Report Share Posted February 6, 2017 Just the stock converter, I think a WFCO. The rig was a 2007. I did check water levels occasionally (maybe twice a year), and boondocked alot for a couple of those years. Link to comment Share on other sites More sharing options...
Jerry Campbell Posted February 12, 2017 Report Share Posted February 12, 2017 I had a 35 amp 12 volt power supply that I used for years when the batteries were disconnected. I only needed 12 volts for forced air heater sensor and fan, water pump and hotwater heater sensor which totaled 17.5 amps. It worked great. If you always have 120 volts there's no need for a battery. I just put in 1600 AmpHrs AGM's so hopefully I won't need it for awhile. Jerry Link to comment Share on other sites More sharing options...
