Integration of the GWL/Modular with Victron Energy products

The reference of theshows the possibility of the integration of the GWL/Modular components with theVictron Energy products.

In this installation the CPM1 communicates (by means of auxiliary relays) with theAUX1 and AUX2 of Victron Multiplus, and the

GWL/Modular – CPM1 - Auxiliary Relays for High Power...

As seen from the demonstration designs provided by GWL and also from the manual of the, the high-power outputs need to be connected by means of the auxiliary relays.

The auxiliary relaysprovide another layer of protection and disconnectionbetween the battery pack e

is an expansion, independent communication extension board designed to be used exclusively. This board expands the battery protection functions and enables remote management of batteries protected by the CPM.

Avoiding petty risks with home storage

Perhaps a small neglection of the maintenance of an airplane can cause the whole plane to crash. Also, a small negligence can cause somerisky situations concerning the energy storage solution.

See two examples from the photos.

A battery pack keeps discharging “by it-self”

Email:Unfortunately, I do not have good news. We faced again a strange situation. The system was not used in the past 2 weeks, there was no grid shortage, the system was not used, and the BMS show that the battery pack was full, please see below the inverter log.

It is obvious from the voltage that&nb

GWL/Modular BMS configuration

The basic configuration of the BMS to be used in the GWL/Modular system.

The proper protection of the battery pack is a must!

We are moving electrons. A lot of them!

When cells are charged and discharged, the volume of the mass inside the cell is changing. This is because the electrons have a mass and this mass is added or removed when charged or discharged.

How many electrons are moved when working with the current of 1 Amp?

The electron flow produces current. T

BMS123 or GWL CPM? - Deeply discharged cells

As our customers are well aware, some type of protection module is necessary to use with every lithium battery for prevention of a deep discharge or overcharge.

I will use the example of our customer from Holland to describe how a significantly cheaper GWL CPM protection can often be the better choice th
