Can Solar Batteries Be Charged With Electricity?

It can be used with an electricity grid to charge effectively and accordingly. In most cases, it is assumed that solar batteries can only be charged using sunshine and light energy.

This power comes directly from the collection of solar panels which is then converted with the use of proper inverters.

Suppose a situation occurs where sunshine is no longer available and the solar batteries cannot access it.

Such occurrences do happen and when they do, electricity is the only option left.

Charging with electricity grids is therefore the only option left to enhance a consistent supply of energy.

Solar batteries and electric surge

It is worth noting that the natural order of things was not meant to have solar batteries charged with electricity.

The input and output of power are not consistent when electricity is used to charge solar batteries.

When solar batteries are charged using electricity for a long time, they become damaged indefinitely.

They end up losing their ability to hold and store charges for a long time.

When this happens, it doesn’t matter the level and intensity of input because the release of power energy will happen quickly and before long, the batteries are flat and empty.

When the battery capacity is less than 1% in strength, the charge controller is not needed to have direct electric input.

The risk is not as high as compared when the strength of the battery is more than 1% in capacity.

However, when these limits are broken, the lifetime of the solar battery is reduced significantly and within a short time, the battery is dead.

This is not what you want for your solar battery especially considering that they are very expensive.

You will be forced to buy new solar batteries when you charge inappropriately with electricity.

But it can also be done safely to avoid these discrepancies.

Control of solar energy with electricity

Power charge controllers can also be used when using electricity as the only charging option.

As aforementioned in this article, it comes at a time when sunshine and light energy is not readily available.

In the same way, there are seasons of the year when sunshine is not available to charge solar batteries.

During this time, power still needs to be used and if the solar panel system depends on sunshine, it is bound to fail and lighting will not be adequate.

You will, therefore, be left without an option other than to use electricity for charging.

But charge controllers are very essential because they prevent the possibility of damaging solar batteries.

The best charge controller for solar batteries using electricity

Not all charge controllers are the same and that is why one should be careful when choosing them.

Only the ones that are exclusive for charging solar batteries with electricity should be used. This is very important because any step mistake will cost the lifespan of the solar batteries.

At a minimum, solar batteries are supposed to last for two years but there are others that can serve even for 15 years depending on the type, make, and other factors of durability.

When you choose the best charge controller, it helps you to safeguard the battery’s lifespan.

The systematic process of electric charging of solar batteries

Charging a solar battery using electricity is a process that is followed systematically.

When all the steps of the process are followed effectively, it helps to prevent further damages that electricity surge, high voltage, and excessive input power can cause to the solar battery.

When you understand this process well, it is not supposed to be misused because the primary intention was not to charge solar batteries using electricity.

It was rather meant to be charged with sunshine and natural light and that means the electricity is just meant to be used in case of emergencies and when sunshine is not readily available.

Understanding the entire process

This process begins with understanding the wiring diagram very well.

The wiring diagram can be studied from the provided manual and if the user manual is not available, the help of an expert should be sought immediately before trying to initiate the charge.

After that step, battery cables should be made, and always ensure that they are compatible.

The compatibility of battery cables is important because it prevents an internal power surge.

The best ones should be used and, in this regard, the highest quality because of accuracy and durability.

Charge controller for solar batteries

Connecting the cables to the charge controller becomes the next step of the process.

The charge controller aforementioned is supposed to be very compatible and reliable for strength. When you use the right one, you will not compromise the quality of your solar battery.

You can go ahead and connect the charge controller to the solar battery and the electric current will from the main source into the solar battery.

The time used to charge depends on the capacity and strength of that solar battery.

When it’s full, the battery sensors will send a signal that will stop charging automatically.

Possibility of electric charging for solar batteries and the consequences

It is worth noting that if the charge controller is not good enough, charging will not stop even when the solar battery is full.

Electric charge is always supposed to be fed into a solar battery to the maximum point and not beyond.

The charge better is lower than higher than the maximum point because the battery will be destroyed.

This is especially so because the design of solar batteries was not meant to be charged with electricity.

You have all the experiments at your disposal but you should be advised that electricity is a possibility to charge solar batteries but there are consequences.


in conclusion, it is possible to charge solar batteries using electricity from time to time.

But it is also important to note that when solar batteries are charged with electricity, they are bound to get destroyed. Sooner or later, they will still lose their ability to store power energy.

However, this happens gradually and the loss of power does not happen all of a sudden.

Little by little, the battery’s ability to hold power is reduced and then lost eventually.

The possibility of charging solar batteries with electricity is there but the consequences are gross.
