Latest News and Updates at shop.gwl.eu

Dear Customers,

With the Christmas season approaching, we expect increased pressure on the shipping capacity of our shipping partners, which may cause slight delays in the delivery of your orders. We apologize for any inconvenience caused by this situation. Our team is working to minimize delays and we thank you for your patience.

Scalable compact Energy Box from the Czech Republic.

AMVOLT's technical philosophy is to build open storage systems in the Czech Republic from individual battery cells and interchangeable standardized components. This significantly extends the life of the entire storage system compared to the now widespread closed, non-repairable battery boxes and drawers.

The AMVOLT LV Energy Boxes are intentionally designed to allow the customer to have the option of any future expansion, modification or service without depending on the AMVOLT itself.

AMVOLT LV Energy Box is designed for 16 pieces of ELERIX EX L280 LiFePO4 cells with an operating voltage of 51.2 V. Battery cells are manufactured according to EN IEC 62619 and have been tested in accordance with this standard (tested by TÜV Rheinland).

Our engineers have created this pre-configured kit for you to build your own photovoltaic power plant. The selected products are therefore 100% compatible with each other.

In addition to the great price, this set impresses with its elegant solution with a Grid-Tied inverter with power limiter, and a scalable ELERIX storage system based on LiFePo4 batteries with an output of 5 kW.

In the package you will also find a professional Epever MPPT, high-quality ELERIX solar panels with a peak power of 410 Wp, a set of connectors, a two-wire cable and stress holders for the panels.

If you still don't know what to do with the wiring, don't despair and call our technical support, which is included in the price. For more information on this set, please see the product detail.

This simple but effective water heating set includes the GF-SUN-2000G2 grid tied inverter and ELERIX solar panels with a maximum output of 410 Wp. It stands out for its excellent price/performance ratio and ease of installation.

The kit is recommended for use in cottages and smaller summer houses where there is a low level of electricity supply, an overloaded power grid or limited possibilities to use other sources for water heating.

The SUN 2000 VA line inverter with limiter (GTIL) is connected only to the boiler electrical circuit and operates only when the boiler is heating water (if its heating is on). This always draws power from the entire boiler so that no overflows to the mains (or indication overflows) can occur. In the event of a failure of the system components (boiler, inverter contactor), the system is protected in the no-current mode by an inverter overflow limiter.

Did this set catch your eye? Take a closer look here.

Don't miss out on modular storage from Cegasa at a great price. Cegasa engineers have designed this energy storage system to create a battery that is simple, fast and intuitive to install, while allowing connection to any 48Vdc inverter, whether it is plugged into the grid or in an isolated installation.

A self-powered system that doesn't need communication to be fully functional, want to know how much power you have? Just look at the charge status indicator.

Risen solar panels (Tier 1 manufacturer) with a maximum output of 400 Wp will be added to our offer. If you are a fan of the all-black design, do not miss the opportunity to pre-order these modules and you can have them at home in 2 weeks. They look really cool on the roof, but that's not their only advantage.

Would you like to check out the remaining properties of these panels? Go ahead and take a look!

By assembling a battery storage system from ELERIX cells, you gain an undeniable advantage over battery "black boxes" from dubious manufacturers.

The individual battery cells are interchangeable, they are not welded together in any way. All components can be easily replaced or repaired thanks to the availability of spare parts.

Our battery packs are therefore fully repairable, which means that we want to realistically extend the lifetime of entire storage systems and thus save the environment.

With ELERIX kits you do not have to be limited by predefined dimensions and battery settings. Build your own battery to suit your needs! Take a closer look at the kits!

We have expanded our range for flexi panels: with these brackets and adhesive, installation is now a breeze!

We know that flexi panels are a very popular choice due to their versatile use even on uneven surfaces and due to their light weight, as they're made from a composite material that is 70% lighter than conventional solar panels, making them ideal for use on house facades, but they will also find their place in off-grid systems such as the roofs of a cottages, caravans or boats. Many of you will be pleased to know that we have expanded our range to include medium-sized 310 Wp and larger 430 Wp panels!

What are the main advantages of flexi 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

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!

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.

Have you ever looked at your roof and told yourself: "Great! Now I'm energy self-sufficient...but I wish it looked better on my roof" ?

Our elegant full black version of a solar panel could help you out in this case and get you rid of this thought.

With a combination of the black color of cells (mono), black frame and black cover of busbars, the solar panel makes an attractive full black design which looks great on a house roof and gives the panel a nice “neutral” look.

The full black design of panels is then the opposite
of the classic poly design, where the poly cells, on the other hand, create a blue-ish look.

Well, just look at the picture, where you can spot the differences :)
