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.
Well, just look at the picture, where you can spot the differences :)More information and pictures:

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.
Check our web page https://shop.gwl.eu/LiFePO4-small-cells/
We are now offering the RT-BMS Cell Ballancing Units (CBUs) with dual power MOFSET transistors that allow the ballancing current up to 10A. The sucess of the balancing function is dependent on proper cooling of the high-power transistors. These must be mounted onto a sufficiant cooler.
