What is the most suitable solar battery for our installation?

If we go to our store to the solar battery category we can find a whole range of options in terms of accumulators, manufactured to meet certain technical requirements in terms of discharge cycles, maintenance, useful life, performance and storage capacity, but what about which are the ones we need for the correct operation of our electrical installation?

Before starting to analyze the point to be discussed, it is convenient to make clear that a solar battery is different and with little to do with conventional batteries, such as those of a vehicle, whose useful life if we perform deep or cyclical discharges is much lower than that of a solar storage tank, so let’s not worry about it.

One of the most economical and recommended models for low and medium power installations are Monoblock solar batteries, ideal for use in basic electrical appliances, for example, light bulbs, televisions, microwaves, among others. However, this solar battery should not be used in electrical installations whose use is daily, since they do not have the amount of useful life cycles necessary so that with daily use, they give us the expected performance.

The useful life of a liquid acid Monoblock is between 3 and 6 years (in float) depending on the model, but if we give it improper use it will surely not exceed one year, therefore, it is best to give it the corresponding use. . The recommended use of these batteries is for weekends and that the depth of discharge never exceeds 50% throughout the weekend, with this we will ensure that the batteries can last between 2 and 4 years.

The recommended maintenance on these solar batteries with proper use will be every 1-3 months (depending on the water that evaporates).

Although it is true that the Gel solar battery and also the AGMs are manufactured in Monoblock format, they have a somewhat higher performance than those of liquid acid and do not require maintenance because they are sealed and composed of gelled electrolytes or in a material absorbent. This type of accumulators are the most convenient for the use of weekends and with the use of various electrical appliances, also supporting without problems the high starting peaks of household appliances and more.

This type of accumulators are the most used in small and medium installations, thanks to their ability to be able to add more equal accumulators in parallel to be able to increase the total accumulation capacity, they also have approximately a useful life of up to 10 years (in float) . With a recommended use in a solar installation, they can last between 3 and 5 years.

The OPZS and OPZV are some of the models that are part of the stationary batteries. They are accumulators that work thanks to their independent 2V cells, with a spectacular load capacity that can even exceed 4500 Ah.

Stationary models are the most recommended to install in homes or farms with medium or high energy demand, and although their cost is higher than the previous ones, it is clearly compensated by their useful life of up to 20 years, even with daily use. .

Considering and understanding the operation of the types of solar battery, we can come to the conclusion that buying the accumulator that suits us best will depend on the size of the solar installation, the use that we are going to give it and of course, our budget, So we hope this article has been useful for you to understand more about solar batteries and if you still have questions and need more information or advice, do not hesitate to contact us.
