With a constant demand from your converter, you run the risk of it overheating and blowing a fuse. And with the converter charging the battery slowly, it doesn’t have to work as hard to keep up with the voltage demand. Your RV battery has a reserve capacity and can provide hours of clean dc power to the needed appliances. Your converter is more of a charger and gives your battery a trickle charge of voltage. You will have limited power and may be unable to run all your appliances. Although it works, I suggest you continue without a battery for only a short time, and here are some reasons why. Issues For Not Having a Battery with your ConverterĪbove, we reviewed that a converter can work without a battery. Without a battery, the converter is doing all the work to supply power which could lead to potential issues. The converter will constantly run as it tries to keep up with the demand of converting the ac power to dc power.Īs you read above, a converter has three modes and is designed to have the battery at some level to work with and keep up with demand. Without a battery, the converter directly provides the needed dc power to appliances. And for the power to be distributed to things such as lights from the battery itself. ![]() With the converter connected to the battery terminal, it is meant to charge the battery. Your RV and converter are designed to get the dc power from the battery vs directly from the converter. Without a battery, your converter works similarly, just not exactly the same way. Since there is little to no load, there is not much need for the converter to work so hard. In this mode, the converter drops to a low 13.2v to keep the battery at full charge. This mode sense that the battery is fully charged, and no appliances or lights are used in the RV. The converter goes in this mode by switching to a boost in voltage and giving the battery 14.4v so it can charge and keep up with the demand of the RV. This mode senses that the battery is not fully charged and will not keep up with the demand. As you use your battery, this mode keeps the battery maintained and fully charged to keep up with the demand of the RV.Ĭharge Mode. This is the mode where the converter provides 13.6v of power to the battery to keep up with the demand of the appliances. Since converting ac power to dc power makes heat, the fan is needed otherwise, the converter would overheat and shut down.Ī converter has three modes of charging a battery, and they include: Have you ever heard the fan going at your breaker panel? That is usually the fan that dissipates the heat from the converter. Once the battery is fully charged, usually around 14.4V, the converter will turn off and stop charging since there is no need. ![]() Whether you have deep cycle batteries, AGM batteries, or even lithium batteries, the converter will give the power needed to charge and extend battery life. It will continue to give the RV battery dc power to keep it fully charged. The converter will act as a charger when you have a battery with your converter. ![]() So without a converter or battery, you would be unable to function things in your camper, such as lights or slide out. This is extremely handy because, unlike your house, your RV does use quite a bit of 12v battery to operate dc appliances: Your RV converter takes 120v ac shore power and “converts” it to 12V dc power.
