Do you know at what temperatures a solar panel produces more electricity? And at what temperatures does it produce less? Which way should the panel be turned and at what angle? Find out in our latest video!

Explore more details and special offers in our portfolio of high-quality solar panels!

Have you noticed that our range of LFP cells has grown by three new additions? ELERIX introduces its 10, 15 and 25 Ah cells. These mini cells will surely make happy those of you who are looking for high energy density cells in a compact package due to limited space!

Intrigued? We thought so. Check out their other parameters!

We have now added the transparent bi-facial ELERIX solar panels with a maximum power output of 300 Wp to our range of solar panels! It means that there is more spacing between the solar cells, allowing more sunlight to pass through the panel. Unlike typical solar panels, they are not affected by high temperatures and lower levels of sunlight.

Have you heard that LiFePO4 chargers have to be big and heavy? What if we told you that it can fit in your pocket? Now literally anyone can install ELERIX LFP 12 V batteries thanks to the "mini pocket" devices for charging, balancing and diagnostics.

Have we aroused your curiosity? Then take a look at the wiring diagrams and related products to find the right combination!

We bring you a brand new range of MEANWELL chargers for LFP cells and batteries! These are 120W chargers that are compatible with lead (flooded, gel, AGM) and li-ion (lithium-iron, lithium-manganese) batteries.

What do you think of them? Like it? Then take a look at their other features!

These premium quality monolithic 12V batteries have no PCM (no electronics) inside. They consist of finely balanced cells with identical power output.

These batteries are suitable for all traction applications including electric vehicles. They are also fully suitable for stationary applications - such as energy storage. They can also be used for starting internal combustion engines.

Order these batteries at a discounted price before they sell out!

Have you heard of LTO (Lithium Titanate) cells? LTO is one of the most advanced technologies in the battery world today. These cells have an amazing lifespan (over 20,000 cycles) and extremely fast charging and discharging characteristics. Add to that the ability to operate in really low temperatures (down to -40°C) and you will never want another cell!

Take a look at the other parameters!

These modules are made using half-cut technology, which means the modules have been split in half - so they have twice the number of smaller cells. This gives them a number of advantages, such as lower electrical resistance and associated better performance. Making the individual cells smaller also reduces the risk of damage due to cracking. By dividing the panel into two halves, the upper part operates independently of the lower part, which is particularly appreciated when one half is shaded.

We are fully stocked with high quality Tier 1 solar modules from Seraphim with a maximum output of 445 Wp. Seraphim was founded in 2011, and has registered impressive achievements in a short period of time, earning Tier 1 Solar Module Manufacturer from BNEF, Top Performer from PV Evolution Labs, and loyalty from demanding customers around the world

Compact but powerful. This is the new EX-L550P LiFePO4 cell by ELERIX with the single cell capacity of 550 Ah. Ideal for stationary use, for example as part of an energy storage system.

Do you think a quality wallbox has to be expensive? Then we will gladly convince you otherwise. This electric vehicle charger is equipped with a 5m direct cable, T2 plug and a power output of up to 11 kW.

Need a powerful, flexible and lightweight solar panel?

We've got you covered - this piece has an impressive peak power of 375 Wp and is made from a composite material that is 70% lighter than conventional solar panels, making it ideal for use on house facades, but it will also find its place in off-grid systems such as the roof of a cottage, caravan or boat.

Looking for a durable outdoor charging station for your electric car? Then look no further. We introduce the OlifeEnergy Wallbox, which is compatible with all electric vehicles on the EU market with an alternating current (AC) power of up to 22 kW. It is designed for outdoor use and installation in the garage, with the possibility of installation in a wall or on a profile anchored in the ground.

The "Base" version can operate locally, i.e. start charging. Automatically as soon as the vehicle is connected or after RfID identification cards. The power of the station can be controlled locally between 0 and 22 kW units.

Are you curious about this product? Check out its other features!

ELERIX batteries are typically characterized by their compact size and high energy density. This is also the case here. Thanks to these advantages, this brand new line is perfectly suited for use in light electromobility (scooters and electric bikes), where every extra kilo and every extra centimetre counts.

What makes the new Elerix Shingled technology so great?

1. The cells are made of strips that overlap. There are no more idle gaps, so the module has a larger active area which increases the power output and module efficiency.


2. The Elerix Shingled modules use an electrically conductive adhesive that connects the silicon strips. This reduces the need for the busbars.


3. And they look nicer

Would you like to learn more? Check out our new YouTube video where we describe the advantages in more detail :)

Do you need to use the cells in parallel to reach higher capacity?

The CORSET by GWL is a metal holder for lithium cells to keep them tight together in a desired shape or configuration.The CORSET is used to support a group of cells and make them into a firm pack. Unlike a customized battery holder, the corset is made of simple, industrially available components and allows to be disassembled and reused.

The CORSET mounts the cells together, holds them tightly and also protects the cells against bulging or swelling. Additionally, the CORSET protects the cells against mechanical damage.
