The need for solar charge controllers for your 12 volt 200ah solar batteries
What can a solar charge controller do for your 12 volt 200ah solar batteries?
12 volt 200ah solar batteries don’t come cheap which is why people often go to great lengths to protect them. A 12 volt 200ah deep cycle solar battery is probably one of the most expensive investments you’ll have to make in order to put up your own solar energy system.
The number one cause for failures of 12 volt 200ah deep cycle solar batteries is subjecting it to excessive or irregular power charges. Thus it is important to ensure that you have a means of preventing your 12 volt 200ah solar panel battery from being overcharged. This is a vital function that a solar charge controller can provide.
Now there are actually times when your solar panels are charging your 12 volt 200ah solar power battery with more voltage than what it is rated for. A solar panel rated at let’s say, 12 volts can churn out 16 to 20 volts towards your 12 volt 200ah solar batteries. This would undoubtedly result in increased current flow towards your 12 volt 200ah deep cycle solar battery and too much of it can make the electrolyte solution within your 12 volt 200ah deep cycle solar batteries to boil which will dramatically reduce battery life and eventually damage your 12 volt 200ah solar power battery.
Monitoring or regularly checking your 12 volt 200ah solar power battery is not enough
Some people may think that they don’t need a solar charge controller to protect their 12 volt 200ah solar batteries as long as they monitor or closely check on their 12 volt 200ah deep cycle solar battery when recharging it. This is actually not the case since the possibility of overcharging these batteries is not limited to ensuring that you don’t exceed the maximum storage capacity or charging time of your 12 volt 200ah deep cycle solar batteries. There are a lot of factors that can alter the voltage output of your solar panels such as ambient temperature and sun’s angle in relation to your solar panels. A solar charge controller can ensure a steady charge for your 12 volt 200ah solar panel battery and limit fluctuations in current and voltage. Although it may cost you more initially with your 12 volt 200ah solar power battery, a solar charge controller is proven to earn its keep by ensuring that you make the most out of your battery’s service life.
