The best batteries for solar panels.

The best batteries for solar panels.

Green energy is one of the most relevant and important modern trends. The generation of electricity from thermal and nuclear power plants entails emissions to the atmosphere and waste, respectively, which is exacerbated by the constant increase in electricity consumption. Solar panels are a very popular alternative source of electricity. Their significant advantage lies in their ergonomics: any resident of the private sector can install panels on the roof of the house, significantly reducing energy costs. Among the residents of Kiev, Kharkov, Dnipro, Odessa and other cities of Ukraine, the so-called “green tariff” is gaining popularity, allowing the sale of generated electricity.

In our online store, special voltage stabilizers are even available, designed for network operation in conjunction with solar panels, which can be bought with delivery throughout the country.

Solar panels, with enough light, generate direct current, which is unsuitable for the operation of household appliances. In this regard, an inverter is added to the circuit, which converts the direct current of the battery into alternating current with the parameters of 220V 50Hz. The intermediate link between the inverter and the panels can be special batteries for solar panels, which accumulate electricity when the load consumes less than it is generated.

The battery market is huge and the variety can easily confuse the uninformed consumer who will have to go to customer reviews and rummage through tons of information to find the best solar battery. We offer you the best option: briefly familiarize yourself with the types of batteries, and then consult with our experts who will help you buy the best batteries for solar panels at a reasonable price with delivery to your city.

The importance of choosing the right battery for solar panels.

It’s no secret that a rechargeable battery is the most common consumable. But it is wrong to treat it as such, because a high-quality and capacious battery is not a cheap pleasure. Incorrect use or wrong choice can quickly render even the best batteries on the market formally unusable, which are simply not suitable for specific purposes.

Traction gel batteries are the best batteries for solar panels.

Solar panel batteries must have a good cycle life and tolerance for deep discharges. Traction gel batteries fully satisfy these conditions due to the technologies used in their production. Let’s take a closer look at them.

Despite the fact that “gel” is a specific type of battery, it is very often called a battery group, which includes batteries with both gel and absorbent electrolyte. They have common features, due to which the performance characteristics do not differ radically. The first and most important difference between solar gel batteries and conventional lead-acid counterparts is the form of electrolyte content.

The composition of the electrolyte itself is not changed, or slightly changed by the use of various impurities, but, more importantly, it is not in liquid form in the cells. In GEL VRLA batteries this is achieved by thickening the electrolyte to a gel-like consistency by adding various silicon and other compounds. As a result, a dense, porous mass is obtained.

In the AGM VRLA battery, an ordinary liquid electrolyte is used, but it is absorbed by special porous glass fiber gaskets tightly packed between the electrodes.

In both cases, the contents of the battery are in a sealed case. Both the gel and the absorbed liquid electrolyte provide a process such as gas recombination. Water vapor, consisting of oxygen and hydrogen ions, does not escape to the outside, but recombines into the water. This saves the user from having to top up with distilled water throughout the life of the batteries.

That is why they are called maintenance-free.

Often users are faced with the question of which of these two types of batteries is the best for solar panels. Both, of course, are good, but there are differences. The GEL battery has a slightly higher cycle life, such batteries are the least sensitive to deep discharges, however, in contrast to this, AGM offers better current output and less sensitivity to charging accuracy. Of course, it is quite difficult to generally compare battery classes, since the performance characteristics largely depend on which technologies the manufacturer uses.

Two batteries from different manufacturers, which are identical in numbers, can produce completely different indicators. That is why, when choosing a battery for solar panels, familiarity with the merits of a particular manufacturer through reviews and discussions from other buyers plays an important role. Also, specialists of the Voltmarket online store will gladly share their knowledge, where you can buy the best batteries with delivery to Kiev, Kharkov, Dnipro, Odessa and other cities of Ukraine.

Selection and connection of batteries for solar panels.

Having decided on the type of battery, which, in fact, is not critical (both AGM and GEL are suitable), it is time to choose the characteristics and number of batteries. As you probably know, the capacity of the circuit can be increased by connecting batteries in parallel, but in practice, when used with solar panels, they do it a little differently. A solar inverter requires a certain DC voltage to be applied to the input to perform DC-AC conversion. You should achieve this rating by connecting 6 or 12 volt batteries in series.

Solar inverter requires 48 volts? Well, an assembly of four 12-volt B.B batteries connected in series is perfect. Battery MPL110-12 / B6 with a capacity of 110 Ah each, or from eight 6-volt Ventura DC 6-200 Solar batteries with a capacity of 200 Ah. Easy peasy!

When connecting, be sure to follow the instructions regarding the permissible distances and cross-section of the power cable.

As you can see, there is nothing difficult in choosing a battery for solar panels. The main thing to remember is that the best and, most likely, the only correct option is traction gel batteries. Also a novelty based on them – carbon batteries will suit you. You can use traditional car batteries, but their rapid deterioration when used in cyclic operation will quickly require replacement.

Having installed high-quality traction gel batteries for solar batteries, you can forget about the maintenance of the battery pack for 5-10 years, enjoying the result of the work of “green technologies”.
