Sometimes when you teach a subject you can't assume knowledge of all of the fundamentals. Those high amperage 12 volt draws demand an adequate battery bank and large cabling to reduce wiring voltage losses.īTW, no female bias here. Actually, due to the inefficiencies I cited before the input current is actually more, but 10:1 is easy to figure. If you draw 10 amps of 120 volts AC power from your inverter, you will be drawing 100 amps of 12 volt DC power from your batteries. The other thing to remember on inverter systems is the 10 to 1 current ratio. The one time I forgot, the system didn't run too long before the batteries went down. I turn off my converter/charger breaker when I run my AC system on inverter power. To get a better idea of the type of RV electrical systems used in your unit, take a look. Though most are similar, RV electrical systems can vary among different units. It's all one closed system in that configuration. The distribution center is where the fuses and circuit breakers are located and where the power is rerouted to the appliances and the converter for 12 volt electric sources. This is because both the inverter and the converter are not 100% efficient and waste energy, and you cannot put more energy into the battery (charging) than you take out of the same battery (discharging). and headquartered in Middlebury, Indiana manufactures Coachmen branded Class A Motorhomes, Class C Motorhomes.
The problem with using your inverter AC output to run your converter/charger is that you are just wasting energy from your battery - you are not effectively charging your battery as you take more energy out of the battery to run the inverter than the converter/charger puts back into the battery. Coachmen RV, a Division of Forest River Inc. The INVERTER does the opposite - it takes in current from the battery and outputs AC power like you get from the shore power cord. It also normally charges a battery so that you can use these devices (along with higher current devices like landing gear) when not plugged in. by converting incoming AC shore power into 12 volt DC power. This means the converter runs at 12 volts, as do the batteries. It will run your lower current 12 volt DC devices like lights, etc. Most campers will run on a 12-volt DC electric power system. Parallax Power Supply (8345) 45-amp Converter/Charger 9. WFCO WF-9855 55-amp Deck Mount Converter 7.
Cantonape 1000W Car Power Inverter AC Converter 6. Progressive Dynamics PD9260CV Inteli-Power 9200 Converter 5. The converter (I prefer to call them converter/battery chargers) is a STANDARD piece of equipment on most every RV that plugs in to AC shore power. PowerMax PM3-55 Power Supply Converter Charger 4. On running the converter from the inverter. From the brand model info, you should be able to find a picture of it on the Google images search. I think you need to call Heartland Service with your VIN number, and they should be able to pull up a build list on your unit, tell you what brand and model converter you have, and where it is.
