question

Issues which are/were reported are still pendling and green mode neither node-red version not solved most of the problems till now.

I tried personally 4 different ESS optimizers. Victron DESS, Victron node red DESS, one optimizer made by Czech company and one made by Polish programmer, you can now him from this forum.

Unfortunatelly Victron DESS is the worst and best one which I am using is the optimizer from Piotr Maciejewski. It is a bit user unfriendly at the beginning, but when you have setup done, you don´t need any more daily or hourly babysitting of your system. Just setup and forget. With full control of all the parameters.

Lets see if we can get this working nicely for you then. First of all, I notice that on your site (assuming that is c0619ab38079) your currency still is set to Euro. Under Settings -> General -> Currency, you can set that to be Sterling.

The maximum import power and maximum output power are also set quite high, or at least higher than I would expect. What is the amperage of your main breaker?

Also your points 1 and 3 seem to clash. In order to mitigate point 3, you'd better switch the system to "green mode".

The system also needs a bit of run time (a few days) without too much tweaking. And your system hasn't been running long stretches for a while.

A colleague also took a look at your system to check why it didn't charge. And he did discover a bug in the system, when the sell price was higher than the buy price. He fixed and released that. So that shouldn't happen again.

Then about gbboptimizer. Feel free to switch to that if that works better for you. I don't mind at all (as long as you use Victron equipment, I am happy). I am personally perhaps a bit hesitant on letting a third party take control on my system. But I am probably more paranoid than most users.
But I did take a look at gbboptimizer a while ago and I found it quite complex to setup. The more settings you can do, will certainly help in getting the optimal results. With the VRM implementation we try to get the best results with minimal adjustments needed in a user friendly way.

Lastly about "outstanding issues being tackled". That is a bit of a general remark, so I'll answer it a bit generic too. We did close a lot of those tickets in the last months. So yes, there is progress and no, the todo-list isn't empty yet.

And please do keep reporting issues; the more concrete, the easier it is for us to look into and to find a cause and solution (dates, times and vrm ids help a lot on quickly troubleshooting). I try to read all messages and react to a lot of them. But as this is quite an active topic I am sure I'll overlook some posts. All time I spend on community is time I don't spend on coding.
