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

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.

One cell is almost never enough for proper energy storage and therefore a stack of cells is needed to reach the desired capacity.

For such a case, we recommend using ELERIX Pack holder which was precisely designed for 8pcs of ELERIX EX-110 LiFePO cells.

All in one packing and our step by step manual makes this kit easy to set up just within a few minutes

The ELERIX holder features:

• Simple and safe manipulation with the cells, easy integration for various applications
• Mechanical readiness for mounting of the BMS components and additional extension modules (DIN rails and punched side plates)
• Full mechanical protection of cells against external mishandling
• Simple access to the individual cells and quick replacement of any cell and other components

Store the energy into reliable ELERIX cells. You power the life!

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 :)

• Fast charging and discharging - max. charge/discharge rate 10C (this means 400 A)
• Wide working temperature range - -50°C ~ 65°C
• Long life time - over 30,000 cycles (with DoD 80%)

Introducing DC powered off-grid energy solutions: DC/AC Inverter Steca XPC 2200 with charger and backup function. The Steca XPC 2200 can be connected both to the battery pack and have the AC grid as the energy backup. The inverter has been tested to work with LiFePo4 battery pack of 24 V. This inverter has high power rating for peak supply and over load capability. This inverter is recommended for off-grid/hybrid installations with the typical supply up to 1600W.

We have increased the offer of various models of the small capacity cylindrical LiFePO4 cells. These cells are ideal for low energy equipment and for many energy applications where tradicional round cells are used. We now carry the 3AH, 5AH, 8AH, 10AH, 15AH and 20AH models.
