About the DESS category

Q&A and troubleshooting DESS
62

I have Installed another 64kWh yesterday and had set the new 214kWh Value in DESS settings, but it keeps ‘setting’ it to the old value 150kWh, i noticed this morning.

Is there a way to verify DESS still uses the new fed value 214kWh?

I did try to set the value in iPad VRM application, beta VRM and normal VRM but it keeps popping back.

Bump. METSTRADE came and went, a good moment to refocus on the year ahead. Therefore I am restating my request/proposal to make DESS a top level category on this forum. My key argument is that a successful future for DESS will require, by nature of the diversity of it’s use cases, a better managed and structured cooperation model between Victron and her most knowledgeable and loyal customer base. What about it @Barbara @guystewart @mpvader

I have the same issue. I am unable to update the battery capacity.

Well i looked in NodeRed for a solution, because DESS gets a bit confused if the SOC is not doing what it calculated.

You can set the value with NodeRed until the VRM DESS battery capacity UI send script is repaired.

If you import this nodes you can set it correctly and check the VRM DESS setting afterwards.
Adjust the inject node to your needed capacity and inject.

Hi @Ersus ,

This is fixed now! We were triggering a ratelimit between services.

With kind regards,
