Creating a post to continue the discussion from here: Deep Sea aka DSE generator controller update - VictronEnergy specifically so I can see any follow ups to @ptrenz comment: “due to the high demand, we are right now working on adding support for the DSE 4520…

Hi @chris211 , support for DSE 4520 MKII was added with v3.50. To start and stop the generator, you wire it as it would use the Relay-controlled start/stop feature, but then select “Connected genset helper relay”. This will then be closed as long as the generator should run and open otherwise. Happy …

Hi @glenborrodaleit , thanks! I’m happy to let you know, that development work is almost completed and this feature will be available for beta testing soon. Here is a preview of how it will work: The DSE 4520 MKII will get available in the device list as soon as it was found via Settings > Modbus T…

Is DSE 6120 supported on the Cerbo GX yet?

Hi @arboldoly , not yet in a stable release. But since the beta release of v3.60~21, we support basically all DSE controllers except for the DSE8xxx range. With the upcoming release of v3.60, it will then be officially supported. Feel free to give it a try! Best

Hi @ptrenz , When will 3.60 be officially released, this version works with the dse6110 MKIII. I want to make it work in a system with 4 MG(304ah) LFP batteries with a Master lv distributor on 3 Quattro’s for a small passenger boat. But I don’t know if the beta version is stable enough.

Hi @Remy , welcome at the community forum! Unfortunately, we do not specify future release dates here, sorry. Also see our community guidelines on that.

Just picking up the conversation from this thread regarding integration with deep sea electronics controllers specifically the DSE 4520 MKII. @ptrenz mentioned that due to high demand, support for this model is in the works. Since it doesn’t support start/stop over Modbus, it’ll use one of the GX…

How do I wire my DSE 4520 MKII to the Cerbo? Can I use the CAN port on the DSE that is meant for motor comunication? Or do I NEED a DSE855 USB to Ethernet communication device and connect it through Ethernet? Or can I connect it via USB?

The controller’s CAN bus for motor communication is not an option. Skimming through previous posts and my memory I would say you would indeed need to connect the controller and the Cerbo together via the DSE855 USB to Ethernet converter. More info here: 18. GX - Generator auto start/stop Post edi…

[image] Deep Sea 4520 MKII & DSE890 Gateway & RS-485 DIY Just wanted to document how I got the new genset feature working using the old DSE890 MKI and an RS-485 connection in case it is of use to anyone else. The DSE890 MK1 does not implement ModbusTCP, like t…

OK. The DSE855 is my next option if I can’t get it to work otherwise. When I’m reading the manual for the 4520 MKII I get the impression that it should be able to connect to other CAN-devices but maybe I’m just interpreting it wrong. On page 20: CAN Port Engine CAN Port Standard implementation…
