Solar Batteries & Deep Cycle Batteries

What is a Deep Cycle Battery?

What is a Deep Cycle Battery?

Deep cycle batteries are like car batteries in appearance, although there is a distinction. Deep cell batteries provide power over long periods. They run efficiently until they only have 40% of their discharge rate left. At this point, deep cell batteries need recharging. To extend the life of your battery, recharge your battery when the internal discharge is 45%. We refer to the level of discharge as the “deep cycle”.

What is a Solar Battery?

Solar power batteries accumulate electrical energy from the sun. They do this by using photovoltaic panels. We refer to the electrical energy from photovoltaic panels as solar energy installation. We also refer to solar batteries as photovoltaic batteries.

The reserve capacity of photovoltaic batteries increases when it stores energy from sunlight. People can then use the stored power either at night or on cloudy days. Solar batteries make a higher current intensity possible. This is more so than with photovoltaic panels. It is especially necessary for the function of electrical appliances used simultaneously.

Can I Charge My Deep Cycle Battery with Solar?

Yes, it is possible to charge deep cycle batteries with solar energy. The charging process works best in remote locations. An example is water-related work or when out fishing. It also applies to electric vehicles and golf carts.

To make this happen, you will need to use solar panels for your rechargeable battery. Invest in solar panels as a solar charger. This solution enables you to enjoy this clean power source.

The time it takes for a 100 Amp hour battery to charge is 5 hours. For best results, use 300-watt solar panels or three 100-watt solar panels for solar energy. These energy density options will give you a more regular deep discharge.

How Many Batteries Do I Need?

How Many Batteries Do I Need?

Battery backup power and the number of batteries depend on the system. The number of solar batteries you need will depend on the size of your solar energy system. It also depends on your power usage. You need to find out what battery capacity you need to power your home or business. 

The most popular battery voltage is a 14-kWh volt battery. These come in a single unit and suit most solar systems between 5 and 6 KW. This system runs an average home in South Africa.

Going off-grid requires a larger battery solution for cloudy days and night time. Battery sizes differ. Find out how many appliances your current solar battery bank powers. This is especially important if you are thinking of energy independence.

Battery types for industrial applications will differ from domestic batteries.


How to extend your deep cycle battery life

Extend the discharge cycle life of batteries by charging your battery slowly. Premature battery failure results from charging your regular battery for only a few hours. Instead, charging your regular battery slowly is preferable. It will prevent premature battery failure.

If your current charger raises internal temperatures, this could damage it. Fast charging can raise the internal temperature of a deep cycle battery, too.

How Long Do Solar Batteries Last?

Expect your regular battery to last between 5 and 15 years. Although battery failure happens in this window, solar power systems can last from 20 to 30 years. Battery failure occurs during the lifetime of your solar system and will need replacing.
