We are happy to provide you with a few suggestions and tools to localise faults in your power supply system
and rectify them if necessary.

Please note that basic electrical knowledge is an integral part of success here.
Please also observe the electrical safety regulations when working on electrical systems.

Here are a few frequently seen problems with independent power supplies:

- Contact resistances or cables that are too thin cause inverters to switch off earlier than hoped.
Or the charging voltage at the battery is not sufficient for a full charge.
Heating of the cables and connections is a negative side effect.
Of course, connections must be well tightened.

The following cable lug connections should be used:





- Incorrect charging parameters do not allow the lithium battery time for cell equalisation,
premature disconnection of the charge or discharge can be the result.




- Error when operating several batteries in parallel, one battery is overcharged and the other is undercharged.

We will be happy to help you with any questions you may have. We can also take care of your problem in our workshop and fix it.


We also offer remote support. Many things are possible with Teamviewer and the like.
The VRM portal from Victron Energy offers a platform for monitoring,
as well as the option of analysing and updating software.

Please make an appointment for this.
