Why can’t I just use my car battery for my solar system? Every day people ask this question and the answer still remains the same –No, you can’t. We can recommend the deep cycle battery. We use a deep cycle battery sometimes called a deep charge battery in off-grid power systems. Solar energy can be charged and recharged as possible to provide sustainable power over a long period of time. It isn’t like a car battery. The car battery is a lead-acid battery. The car battery stays fully charged and provides a short burst of high current for ignition and low current for lighting. In this article, we’ll look at 4 secrets to enhancing the battery lifespan.
How to know the right battery to go for
We cannot over-emphasize the need for deep cycle batteries for off-grid solar systems. It is to our solar systems what food is to our body. You should fully charge your deep cycle battery during the day by the solar panel and deeply discharge after sunset. But the question is: how do you know the right deep cycle battery to go for? Below are a few tips on things to be on the lookout for.
It is important that the voltage rating fits the battery charger and the off-grid inverter rating.
Note the capacity in Ah (ampere-hours)
You want the highest possible. If you don’t get a very efficient battery, you might have to compensate for its inefficiency with larger solar panels. Thus, the need to watch out for this characteristic is very necessary.
A good deep cycle battery lifespan is typically around 3-4 years. Anything below this might put you at the disadvantage of incurring additional expenses.
Secrets to enhancing your battery lifespan
Just like your solar panel, your battery also should be handled with care.
- Keep batteries in a shaded relatively cool place with natural ventilation. If you prefer to keep your batteries in an enclosure for aesthetics, ensure that the enclosure is well perforated to allow for air circulation.
- Ensure that you recharge your batteries fully before depleting them all over again. This is one of the best treatments you can give your battery; it will preserve the battery cells and you will enjoy a longer battery life span
- Use a quality charge controller and inverter from a trusted manufacturer. This is important because your batteries must be getting the right charging current. A low charging current may be insufficient to keep the batteries in good condition since it takes longer to charge fully.
- Check the health of your batteries using a battery analyzer regularly. This will help you avoid sudden power cut-off due to battery failure and aid in early detection of the fault.
So here you have it, the characteristics and care of a deep cycle battery.
