Checking your solar battery bank state-of-charge

Solar panels as we know  are a significant investment, but they can pay off over time because a power source that survives off-grid. And Off-grid systems wants a solar battery bank of deep cycle batteries for storing the electric energy produced.

These batteries are the essential thing for your solar power system, so it is necessary to look after them and keep them working efficiently.

No doubt, solar battery banks and their charge are not still common knowledge, so maintaining them or dealing with a problem may be a struggle. They are expensive, and the maintenance alone makes some people think how else can I get clean energy into my home at the lowest cost?

How can I use clean energy for my main electricity?

It is important for you to remember that you are in control of your home’s electricity use. There is a fact that about to all of us forget. Unless your home is entirely off-grid, and you are relying on a utility company to give you and charge you for your electricity use.

Did you know that you do not need to pay for coal-driven electricity if you do not want to? In a number of states, you don’t have to pay for coal-driven electricity, or have to wait for an unpredictable bill each month. We’re revolutionizing the way we choose and pay for energy so giant, expensive systems like our solar panels are not required to contribute to the world.

How long do solar batteries last?

An average solar battery will usually last anywhere between 5 to 15 years. Moreover , if they are looked after well, their life span can be up to 25 years, which may correspond to the average lifespan of a solar panel.

You have to be aware that the life of a solar battery is considerably influenced by the extreme temperatures. Some batteries will also have built-in protection from these temperatures, but if your battery  does not, you need to make sure that you take the necessary precautions.

At a time When a solar battery is exposed to temperatures under 30˚F, it needs a higher voltage for reaching its maximum charge. Conversely, when the temperature exceeds 90˚F, a solar battery will start to be overheated,

and so the voltage shall need to be reduced so that it does not become overloaded. When either of these situations happens, even if only temporarily, it affects the lifespan of your battery.

Your deep cycle battery shall last longer if the depth of discharge (DOD) is not allowed to get under 50% before it has recharged.

What is a deep cycle battery?

The answer to this short question is simple and interesting. A deep cycle battery has made up with  a group of individual 2-volt cells, which are able to store energy production by photovoltaic grids.

 The cells within the deep cycle battery convert unused electrical energy in the form of chemical energy, which then again converted back into electrical energy only when it is needed. These batteries are called “secondary batteries”  . The reason for their name is that they can be recharged and used again and again for years.

How do I measure solar battery charge?

Solar battery charge can be measured in terms of state-of-charge and the other known name is as the voltage within the battery. If you are interested to know how to check what charge your solar battery has, just keep reading!

What is the state-of-charge of a battery?

The state of charge is about how much charge is left within a single deep cycle battery or solar battery bank. The state-of-charge voltage depends on the type of deep cycle battery being used. This can be a sealed or may be flooded lead acid battery, or a gel battery, or an AGM battery, and it will further vary for different brands.

The average age of the battery, along with weather or climate conditions, shall also affect the SOC of a battery as they eventually cause of a reduction in the full amount of charge a battery can hold. This is why it is much needed to check the SOC regularly so we can ascertain the health of each deep cycle battery in the solar battery bank.

How do I check a battery’s state of charge?

This is for those who don’t have a solar voltage regulator or a solar charge controller, the simplest way for checking a battery state of charge is to check it with a multimeter.

A number of lead-acid batteries will be fitted with a removable cap that will also enable you to measure the specific gravity with a hydrometer, which is the most reliable way to find out the state-of-charge. This is what tells you the SOC voltage in a cell of the battery.

Ensure that you only take battery SOC readings when it is not receiving any generated or other charge. In simple words, at night or on a dark day. This means you can not obtain a more accurate reading than if the battery were being charged.

How do you recharge solar batteries?

Solar panels charge deep cycle batteries by the use of a solar charge controller. The controller makes sure that the maximum possible output of the solar panels is put into your batteries without being overcharged.

A solar battery bank will also take in an unusually high voltage when it is first being charged at the time when the battery SOC is at its lowest. As the deep cycle battery will absorb more and more charge, the rate of charge will slow down at least until it is fully charged.

If, for any course, you want to charge the battery without a solar panel, Now you can do so by using a standard mains battery recharger.

How long do solar batteries take to charge?

The duration of time taken depends on what a solar power battery will take to charge depending on its type of deep cycle battery being used or its size.

In General, a solar panel that used to provide 1 amp of electrical energy can able to charge a battery fully in 5 to 8 hours in full sunshine, but this time can be increased as the angle of the sun changes or it becomes overcast.

What is Wrong With My Solar Charge Controller?

After learning about the answer of how to check if a solar panel is charging a battery, it is time to further explore what is actually wrong with your solar charge controller. A solar charge controller is used to manage the amount of power travelling from the solar panels to your battery.

It protects the battery life by making sure that the battery does not overcharge during daylight hours. And  If your solar charge controller is having issues, there may be many reasons behind it. To find out the problem, you need to go backways and search for its cause. The problem could be with the panels, batteries, wiring, or the charge controller itself. There can be a few reasons for it.

Solar Charge Controller Not Charging Battery

If you discover your solar charge controller is not charging the battery or that the charge controller will show 0. Amps when charging ,might be an issue with the wiring, input voltage, or photovoltaic panels.

By considering the following things into the mind you are able to find the reason:

  • firstly Check if the battery is full, and if the battery is totally full or nearly full, the amps shall drop low.
  • Then  Check if your solar panel is clean and in a properly sunny location. Dirty solar panels may lead you to poor power output.
  • After that Check for input voltage. It has to be around 18V, depending on your solar panel’s rating.
  • Then Check the wiring between the solar charge controller and with  the solar panels.
  • After all of that If you are still unable to find the cause,then you need to perform a hard reset.
  • And it If it still doesn’t solve the problem, then the last optuion is that you should just install a new charge controller.

The Controller isn’t receiving voltage from the solar panels

Apart from the solar charge controller not charging the battery, the controller may also not be receiving voltage from the solar panels. If you notice a moon symbol on your charge controller in the daytime, that means your controller isn’t receiving voltage from the solar panels.

  • First do this, from the back of your controller, remove the available connected  two solar panel wires.
  • For measuring the voltage across the two wires, you need to  use a multimeter. The voltage should be near to 18V,  this thing is depending on the rating of your solar panels and the generated  amount of light.
  • If you find out too low a voltage, then you have to use a multimeter to check the voltage from each panel. These also should be around 18V. If one of those panels has a much lower voltage than the other, there is likely a problem with that panel.
  • For If all the panels have a 18V voltage reading,you should  check the wiring for a connecting issue.

The Controller Isn’t Turning On

This can be Because of wiring issues or for an incorrect system configuration, the solar charge controller may not be turning on. For solving the problem, you must rewire the system and if it still does not work, restrain the controller. After this, you may as well see how to know if my Renogy solar charge controller Is working.

Energy Production

Checking out the energy production of solar panels. If you have a solar energy monitoring system, it can easily provide real-time data of the amount of energy  your panels are producing now. 

After knowing it you have to Compare this with your battery’s capacity to know whether the energy generated is sufficient for charging. and  If the energy production is consistently low or is insufficient to charge your batteries, it might be indicate a problem with the panels, for example a poor positioning or reduced efficiency.

Conclusion:

To warranty that your solar panel system is strongly charging your battery, it is necessary to regularly scan the battery, solar panel, charge controller, and related wires.
