What size RV converter do I need?

Make a note of all your DC appliances and the amp rating of each. If only a power rating is given (watts), divide it by 12 volts to convert it to amps. Add up the amps of the appliances you’re likely to use at the same time. This is the minimum size power converter needed.

Can I put a larger converter in my RV?

Going to a larger sized converter will not change your charging rate. The output voltage determines how many amps are provided to your batteries. If you’re getting a 30 amp charging rate from a 45 amp converter, you’ll get the same rate from a 60 amp because the output voltages are the same.

How many amp converter do I need for my RV?

RV converters do provide a charge to your RV house batteries, but only a small portion of the converters amperage rating is used for this. Normally 3 to 5 amps, which are not nearly enough to charge batteries that are discharged.

What size inverter do I need for RV?

Depending on size, most RV’s should operate off inverters rated at 2000 to 4000 watts (continuous). Generally, inverters will supply surge loads of 1.5 to 2 times their rated continuous output to allow for high demand start up loads such as fridges and compressors.

How many volts should my RV converter put out?

If the meter reads between 12.3 to 12.9 volts, it means the converter is working properly. Anything less or more, and you may need to do some troubleshooting.

What is the difference between an RV inverter and converter?

The Converter transforms AC Voltage to DC Voltage or 110V to 12V in an RV. An Inverter transforms DC Voltage to AC Voltage or 12V to 110V in an RV. Both transform voltage, but in opposite directions.

Will an RV converter work without a battery?

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.

Does my RV converter charge my battery?

Answer: The battery charger in the RV converter provides a trickle charge and is only designed to keep the coach battery(s) topped off. It is not designed or capable of recharging a battery that is completely discharged or damaged. The automotive alternator also charges the coach battery when you are driving the RV.

Should I leave my RV inverter on all the time?

ALWAYS leave batteries on charge. Leave inverter turned ON. With the inverter turned on the batteries will provide 120 volts to the residential refrigerator (assume you have this as you have an inverter) in the event of a power loss. If it is turned off, and an outage occurs then there is no power from the inverter.

Can an inverter run an RV air conditioner?

Most fifth-wheel trailers and Class A motorhomes come with two to three air conditioning units. Thus, in order to run all two or three air conditioning units, you will need a larger power inverter, perhaps as high as 7,000 watts. No RV or motorhome comes equipped with that high of an inverter.

How do I know what size inverter to buy?

As a general rule of thumb, the size of your inverter should be similar to the DC rating of your solar panel system; if you are installing a 6 kilowatt (kW) system, you can expect the proposed inverter to be around 6000 W, plus or minus a small percentage.

What size inverter do I need to run a TV?

Site Team. Almost any of the inexpensive 250 to 300 watt Modified Sine Wave inverters will work. The secret is to mount the inverter within a few feet of the battery and run short, fat wires directly there so there’s minimum voltage loss on the 12 volt side, then extend the 120 volt wires to the TV/VCR.

Where is the power converter in my RV?

The most common spot to find your converter is near your control panel. You will likely see a small vent or fan near your control panel that is an obvious sign that your converter is near. Whenever you buy a new or used trailer, it is essential to know how your RVs power works.

Turn the lights on inside the camper. Open a water tap and listen for the water pump to turn on. If all of your accessories are operating as normal, your inverter is functioning normally.

How do I test my RV converter?

The first thing you’ll want to do is use your battery voltage meter to test across the 120V AC terminals. This will let you know whether or not power is being sent to the RV battery converter charger. Then, plug your RV into shore power or a generator. The reading on your voltage meter should be about 120V AC.
