I’m aware that there are quite a few complaints about DESS out there. I’ve experienced some issues myself when I first activated it during the winter last year. After using only ESS during the summer, I decided to give DESS another try — and from what I’ve observed, it’s performing much better now.
Of course, there’s always room for improvement, and I’m confident Victron is continuously working on enhancements. Still, on many days, DESS does a pretty solid job.
Take today as an example: we’ve had little sunshine for several days, but the wind is blowing, which made energy prices low overnight. DESS purchased a few kilowatt-hours for just 17 cents, helping us get through the day without drawing power during peak pricing periods.
Admittedly, at the moment I don’t have any large consumers that are difficult to predict, such as an EVCS.
Let’s not forget to share positive feedback too! So Thank you Victron for the improvements
