Solar panel systems are made up of many different pieces of hardware and equipment, all of which will need to be powered by various forms of direct charging or battery circuits. 

Inverter batteries come in two forms, simple power start-up batteries inside the inverter hardware, but also consider the inner battery components and how they are powered; inverter batteries rely on AC/DC currents to work. 

When it comes to solar batteries, they will be literally powered by the sun and the panels’ ability to collect said energy and convert it into storable electricity, which then can be used by components like the inverter and its battery systems. 

What are the Differences?

Focusing on the components and hardware, then going along with these two types of batteries, we find that solar batteries will charge solely on the sun’s power. 

At the same time, the inverter batteries will be simpler in design plus require DC/AC currents to function properly. 

Solar panels will feed the batteries after the electric current is sent through a converter that takes the sun’s electricity and turns it into a DC current. From there, most systems send that power to the batteries for storage. 

Some household systems will have a switch that will send some of the current to an Inverter to power its components, including filling the batteries. 


What are the Similarities?

We will start with both batteries’ ability to be present in a solar panel system, and both will play a vital role in completing the complex circuits needed to utilize the power of the sun. 

In addition, these batteries will have to work with DC currents, which will be sent from a converter to the desired hardware, to the batteries for storage, and to the inverter to be used by the household. 

Some systems will have the inverter as part of the battery exit path, the power will be stored in the solar battery, and the inverter’s hardware will use the stored energy to power up. Making these two concepts one and the same for some system setups. 


Pros and Cons: Solar Battery vs. Inverter Battery

When it comes to the inverter, a possible con would be the fact that it will require an AC/DC current to function, while limited direct charge inverters will have to start up batteries. 

However, the pro will be that these batteries are efficient and do not require much power to fully charge or function. 

The pro for the solar batteries will be that they will be made with the newest high-tech materials to ensure a quality and lasting charge. 

The con will be that most solar batteries are the size of two or three six-foot men, which makes them hard to move, and they take up quite a bit of space. 


Which one is More Common?

This will easily be the solar batteries, which will be a part of even the simplest of solar panel charging systems. 

There will be charging systems that will be solely the panels and the battery, and other systems will be just as simplistic, which leads to bigger and more complex systems. 

These solar panel household systems, and the larger solar farm setups, will have multiple stations and points for the power to travel. 

The common home systems will have the solar battery, and many will have the inverter with a battery, while the larger solar power stations will need junction boxes, many of which will have inverters with batteries. 


Which one is More Efficient?

The answer to this question might surprise you, and the inverter will be more efficient. When it comes to the solar battery charging process, there is a round trip efficiency of around eighty percent. 

The lower-level inverters will work with a capacity of eighty-five percent, while the newer higher-tech models will have an efficiency rating of around ninety to ninety-five percent. This is easily five to fifteen percent more efficient when it comes to power utilization and waste. 


Final Thoughts on Solar Battery vs. Inverter Battery

When you look at household solar panel power systems, you can see that the inverter and converter systems act like circuit breakers. Therefore, it is important to have fail-safes when it comes to electricity, especially when collecting and storing power. 

These two pieces of equipment will prevent any damage to the solar battery during collection and prevent any harm to the household grid or, if applicable, to the large power grid. 

Batteries are the key to solar power generation. When the batteries improve, so will the efficiency of the systems. 

Keep an eye out for innovations to these batteries or to the collection panels. These technologies are constantly improving and changing.
