The Lead-Acid battery is the type most utilized in solar energy systems because, although it may be the earliest (100+ years), this is also the particular cheapest and many trusted for the purpose of saving solar-generated electricity.
When these types of batteries fail, this is usually for one of 2 reasons:
Lead sulfate has built through to the plates inside battery. In a majority of all circumstances of lead-acid electric battery failures, this is usually the cause.
You could have run them down too low too frequently.
The biggest reason with regard to failure is the particular buildup of prospect sulfate, which is called “sulfation”. There are a few main reasons why sulfation occurs:
A person are not re charging the battery after use
The battery charge stays listed below 75% for the long period of your energy
The battery is not really getting 100% charged when you perform recharge that
Your current battery gets too hot (usually over one hundred degrees F) with regard to a prolonged period of time
The liquid in the battery (electrolyte instructions a combination of water and sulfuric acid) becomes lower due to evaporation. This exposes the lead plates to the particular air and the sulfate crystals start to build upward.
Fortunately, there are usually ways to fix this.
The 1st way is the simplest… if you need a high-quality 4-stage battery-charger. The very first 3 stages or units of the battery charger have in order to do with typical charging situations. Typically the so-called 4th period is specifically for aid with the issue of sulfation by simply a method named “battery equalization”.
Equalization is a means of overcharging a battery inside of a very managed way to dissolve the lead sulfate uric acid. Since sulfation is definitely the primary reasons why big storage batteries die, it tends to make sense to get a commissionner (or charge controller) that provides this kind of service.
Unless sulfation becomes very extreme, it is generally fixable.
Too Many Deep Cycles
The second main reason for battery disappointment has become too cleared lots of times.
Total, the less a battery’s reserves are used, the longer it will last. battery balancer Though the caution with this is that in case you don’t sometimes “deep cycle” it (discharge it sufficiently), it will create up sulfate debris. However, assuming you are using that down to about 45 or 50% involving its total supplies about once for every month, this need to not have to get an issue.
The more you deeply drain the battery, the quicker its life. The majority of lead-acid batteries only want to be drained by 40 or 50 percent. If you depletion it down to, say 20% or even less from the overall reserve, you may well be drastically shortening living of the battery.
