Benefits of Solar Battery Maintainers
Solar Battery Maintainers have been around for many years, but very few are aware of its utilities. They view these units as an additional investment. However, the truth is different. There are many benefits of having a solar battery maintainer. We have mentioned the main ones below:
Fully Charged Battery
In many cases, the battery shows the surface charge to indicate a full charge while it is not actually, which usually happens when you use a high current or boost charge the batteries. Solar Battery Maintainer trickle charges your battery by releasing a small and consistent amount of current. Such charging may take a bit more time, but it will ensure that the battery fully charges.
Optimal Performance
A battery delivers optimal performance if the charge is at an optimum level. You can use the solar unit even if it drains up to 50%. Using a solar battery maintainer ensures the charge never drops below the minimum level; this maintains optimal performance and also extends the battery’s lifespan.
Peace of Mind
Battery Maintainer charges the battery when it is running low and maintains a floating status on a full charge. It regulates the charge of the battery even when you are not around to keep track of it.
Ultimate Buyer’s Guide – Solar Battery Maintainer
Steps of Battery Charging and Maintenance
Solar Battery Maintainer charges and maintains battery charge on eight steps mentioned below:
- Desulphation – It reconditions batteries that have lost power due to long-time non-use.
- Soft Start – Charging of the battery until the terminal voltage rises to a preset level.
- Bulk – The primary charging step charges the battery below full charge.
- Absorption – This final charging state keeps battery voltage at a preset level.
- Analysis – It suspends the charging phase and measures the voltage.
- Recondition – Maintainer feeds a constant current to the battery to ensure maximum voltage.
- Float – Maintains a constant voltage level of the battery.
- Pulse/Maintenance – Sends a pulse of electricity to the battery when the charge falls below a preset limit, so the battery retains its condition for longer life.
Things To Consider When Buying A Solar Battery Maintainer
Now that we have mentioned the benefits of a solar battery maintainer, you might want to know about the things you must consider when you pick one for your house:
Automatic
Manual settings are challenging to maintain and can be operated only by professionals, so make sure that the maintainer you purchase has an automatic setting. An automatic maintainer charges your battery in fast mode, and then it switches to the top-off mode that slowly brings the battery up to its maximum level. Finally, this setting enables the maintenance mode that keeps your battery at full capacity for an extended time.
Charge controller
All solar panels need a charge controller between its panel and the battery to prevent overcharging. Some solar panels have built-in charge controllers for battery charging and maintenance. If the unit does not have one, you can buy a kit that includes both the solar charge controller and solar panel.
Deep-cycle battery maintenance
You must purchase deep-cycle battery maintenance for your solar battery maintainer. It can induce the Equalization and Desulphation phase. This property of the Deep cycle battery maintenance helps to prolong the battery life of your audio equipment, motorized scooter, RV, or even floor sweeper.
Load Testing
Whenever you have a battery-related issue, it may not be immediately apparent whether the battery is faulty or if it is a problem with the charging system. Choosing a solar battery maintainer with a Load Testing capability helps to identify whether there is an issue with the battery or the charging system.
Mounting
Make sure the maintainer you choose has complete flexibility in angle and azimuth, which allows the solar panel to move automatically in the direction of the sun to produce the most power.
Single-frequency vs. multiple frequencies
Single-frequency maintainer removes only the newly formed sulfate deposits from the solar panels but fails to recover a heavily sulfated battery. Only a multiple frequency maintainer can remove both old and newly formed sulfate crystals in the shortest time possible.
Start Assist
This feature in a solar battery maintainer helps you to utilize the dead batteries even if the power has dropped below the starting threshold.
Spark proof
Spark proof is the connection in a maintainer designed not to produce a current unless it detects a proper connection. Such a smart feature prevents sparks when you connect a charger, thus avoiding fumes and explosions.
Warranty
A solar cell is not a perfect unit, and it might come with one or more damaged cells. To avoid the hassle of replacing the panel frequently, we recommend you pick the solar battery maintainer with the most extended warranty available.
Waterproof and weatherproof
Solar battery maintainers also need to be robust enough to withstand the harsh off-grid environment such as rain, heat, dirt, and dust. So pick the one that is portable, tough, and IP65-rated for water, dust, and impact resistant.
Frequently Asked Questions
What is a solar battery maintainer ?
It is a device that induces optimal battery performance. A solar battery maintainer prevents batteries from overcharging and complete discharge. It also improves the charge quality giving you the liberty to run your devices at any time.
How do solar maintainers work ?
A solar battery maintainer, like any other solar device, converts the energy from the sun into electricity. Then it supplies the necessary power to the batteries, and if fully charged, cuts off the power to prevent damages due to overcharging.
Do I need to put the solar battery maintainer under direct sunlight ?
Given that solar devices work best during day-time, you don’t necessarily have to put the units under direct sunlight. Unlike low-quality panels, high-quality panels will overcome weather conditions and work well even in cloudy, humid conditions.
Closing Words
Investing in a solar battery maintainer is a smart and easy way to solve your battery-related issues. Before you purchase one, make sure to check its details and features, and refer to the buyer’s guide.
Don’t forget to check for any extra costs before you plan to make a purchase. This guide to the 10 best solar battery maintainers will also act as your guide, now that you know that getting yourself such decent technological units is a smart choice in itself.
