Solar panel system batteries

Solar panel systems are becoming increasingly popular as people look for environmentally friendly and sustainable energy sources. However, efficient storage solutions are needed to increase the efficiency of solar PV systems and stabilise energy production. Therefore, batteries are essential for the operation of solar PV systems to ensure that the energy they produce is not wasted. The solar system batteries we sell are available from the following manufacturers: Victron Energy, Green Cell, VoltPolska, Perfektium and Pytes.

HERE ARE SOME IMPORTANT ASPECTS TO CONSIDER WHEN CHOOSING SOLAR SYSTEM BATTERIES:
Energy storage: batteries allow you to store the solar energy they produce, so that energy remains available when the solar system is not producing enough power, such as at night or during cloudy weather. This allows for continuity of energy production and self-sustaining systems.

Capacity: the capacity of the battery determines how much energy it can store. When choosing the capacity, the energy consumption and the desired operating time must be taken into account to ensure that the battery can supply sufficient energy.

Voltage: Solar PV system batteries are available in different voltage ratings, such as 6V, 12V or 12.8V. For higher power, these batteries should be connected in series to a 24V or 48V system. The higher voltage means lower losses and lower currents, which means that a smaller cross-section cable may be sufficient and is more cost-effective. We also offer compact battery solutions for 48V systems. Examples are the Green Cell Powernest and the Pytes E-Box 48V LifEPO4 energy storage systems. It is important that the voltage of the battery you choose matches the voltage of the other components in your system, such as solar panels, charge controller and inverter. 

Type: Different types of batteries are available, such as lead-acid (AGM or VRLA), lithium-ion or lithium-iron-phosphate (LiFePO4). Each type has its own advantages and limitations. Lead-acid batteries have the advantage of a lower price, but have a limited capacity (around 50%). LiFePo4 batteries have up to 90% of capacity and can be charged and recharged at significantly higher currents than their lead-acid counterparts, but can cost several times more than an AGM battery. It is therefore important to consider system requirements such as lifetime, cycle stability, maintenance requirements, etc. when choosing the right type.

Durability and lifetime: battery durability and lifetime are important factors. Modern batteries, such as lithium-iron-phosphate batteries, can have a longer lifetime and can better withstand the cyclic charging and discharging cycles that are typical in solar panel systems.

Manufacturer reliability: products from reliable and reputable manufacturers tend to offer better quality and performance. It is important to choose products from manufacturers with experience in solar system batteries and a reputation for quality and reliability. Victron Energy, Green Cell, VoltPolska, Perfektium and Pytes are manufacturers that are well respected in the market and their products are widely used in solar PV systems.

Environmentally friendly features. Lithium Iron Phosphate (LiFePO4) batteries, for example, can be an environmentally friendly alternative to lead-acid batteries, as they contain less harmful substances and have a better lifetime and efficiency.

Installation and maintenance. Some battery types may need regular maintenance, while others may be maintenance-free. Make sure you are aware of the maintenance requirements of your particular battery and find them easy to manage.

Warranty and support: always check the warranty conditions for your battery. Always check the battery's warranty.
