The 12V power needs to be reduced so it won’t overpower the device.ĭC-DC converters are also used to charge one battery bank from another. They’re also commonly used with deep cycle batteries to drop the voltage to charge phones or laptops. A DC to DC converter can reduce the 24V to 12V in order to power the radio. For example, a truck might have a 24V battery. We’ve discussed inverters and battery chargers, but what about DC to DC converters? What are they used for and how do they work? When Is It Used?ĭC to DC converters are useful when the voltage coming from a battery is too much for the device it’s powering. These units can convert power in both directions, from AC to DC and DC to AC. Many off-grid installs prefer to use an inverter charger combination unit. Thus, when you plug your RV into shore power, the battery charger takes the AC power from the grid, transforms it into DC energy, and charges your batteries at the voltage they need.

These chargers are used when plugged into the grid or when running a generator to charge batteries. Most RVs, boats, and other mobile electricity systems will have a battery charger (or AC to DC converter) connected to the house batteries. And because all batteries need to charge at a specific voltage, battery chargers also limit the current and voltage to avoid overcharging the battery. How Does It Work?īattery chargers (i.e., AC to DC converters) work by rectifying and filtering the electricity to remove all AC components. An inverter allows the occupants to actually use the electricity that their solar panels are generating.Ĭonverters or battery chargers are usually built into most RVs and boats. Most solar and wind generators also only produce DC power that needs to be fed to batteries first. This is why all household, RV, and boat off-grid setups usually have an inverter as one of the main parts of the system. Because batteries output DC power, you’ll need a DC to AC inverter in order to power most household devices (unless it’s a 12V electronic). When Is It Used?ĭC to AC inverters assist battery storage systems and off-grid power. Once the power has been converted, it runs through a transformer that changes the voltage to the desired output. It converts DC power to AC power by rapidly switching the direction of DC input back and forth between positive and negative. AC is generally created by a rotating generator that an inverter needs to simulate. Inverters work by electronically generating an AC waveform from DC power. This includes how it works and how we use it. Now that we’ve covered the basics let’s take a deep dive into converting DC power to AC power. It’s also why we invert battery power AC power to run common household devices. This is why we convert AC power to DC power to charge a battery.
Lastly, DC power is the only form of electricity that you can store. There are exceptions to this voltage, however. Generally, DC power operates at lower touch-safe voltages under 50 volts whereas AC power operates at a few hundred to over 1 million volts. Because of this AC power is stepped up to very high voltages to transmit long-distance and is used for the power grid. AC power can have its voltage changed very easily whereas DC power is more complicated to change the voltage. DC stands for “direct current,” and AC stands for “alternating current.” Therefore, with DC energy, the electrons are only flowing in one direction, and with AC energy, electrons flow in alternating directions.Īnother main difference is voltage. The fundamental difference lies within their names. There are several differences between AC and DC power. → Dive Deeper: What Is an RV Battery Inverter? What’s the Difference Between DC and AC Power? Thus, the device you get to convert your battery power into 110V power through your outlets is called an inverter, while a battery charger is an AC to DC converter. However, the term “converter” typically refers to an AC to DC converter (or a battery charger), while “inverter” refers to the process of changing DC power to AC power.īecause RVs and boats do not always require an inverter, but always have a battery charger, the general term used for the battery charger was the converter. Therefore, the difference between “inverter” and “converter” is really just terminology, and many people use them interchangeably. Technically, the word “converter” means to change.
