To find out what is the difference between 12v and 24v in the battery systems, we ought to understand the basic definition for each first. 12V tells us that the battery supplies 12 volts under a nominal load. The same principle holds for a 24V battery bank in that it provides 24v lithium ion battery. 12V LiFePo4 batteries are utilized in most vehicles as a result of the electrical parts like the starter, lighting, and ignition systems are designed to control on 12 volts.

The 12-volt rating of a battery is the nominal voltage and it should be slightly higher or lower reckoning on the state of charge and loads. We typically use 24V battery systems in larger trucks and buses because of the vehicle’s higher power needs and long cable runs. you’ll also look at 24V utilized in larger boats and a few RVs with elaborate solar systems.

What is a 24V Battery?
One way to form a 24V system is to use a 24V battery. 24V LiFePo4 batteries are less common than their 12V counterpart and are tougher to come back by. 24V batteries are comparatively expensive.

However, they are doing take up no space than running more batteries in a series. So, if space could be a concern, a 24V battery is also a stronger selection for you.

12V System advantages
Most vehicles use 12V systems as parts used in vehicles are designed to control 12V. When it involves RVs, most appliances like recreational vehicle refrigerators and lighting also work on 12V. 12V systems only need a battery and work well for low-power applications and short wire runs.

12-volt systems are nice for their simplicity and most recreational vehicle appliances work with them. Smaller solar systems are also easy to attach to them.

24V System advantages
24V systems are helpful as a result you’ll use smaller diameter wire and cut back electrical phenomenon by twice. If using smaller diameter wires will cut back wiring prices and reduce the space needed to run wiring. This is often particularly necessary wherever long wire runs are needed.

But wait, however, are you able to run a smaller wire with more voltage?

You can run a wire 2x smaller than a constant 12V circuit. This is often due to the higher voltage needing less current to provide a similar power. Since we may be running less current or amps, we can use a smaller wire. This is often a similar reason power is transmitted on power lines at terribly high voltages. The wires are often many, smaller, and carry lots of additional power!

When building out larger portable solar systems victimization higher voltages like 24 volts or 48 volts is extremely helpful. This is often Geo Astro RV’s set up with thousands of watts of solar.

In addition to smaller wires, 24-volt systems operate additional with efficiency in motors and inverters. Often, a similar solar charge controller operational on 24V vs 12V can handle doubly the solar input.
