Hi all, first few weeks with Victron in my home and overall I think it’s a beautiful system and am so happy I chose it.
Everything was working flawlessly with DESS for me in that the batteries were charging at my fixed 9c window each night with the solar charging the battery during the day then feeding in the excess for 19.5c. During the peak periods of the evening we’d be running off the battery. So a complete shift to off-peak and renewable electricity. Very happy.
Then I noticed our location wasn’t set in VRM. So I did that but now curiously we have these grid buy prices that are all over the place and vary as I click tomorrow, next-day. I tried setting them and turning DESS off-and-on but seems a glitch?
I’d love to get this back as right now our battery is charging from daytime grid!
Thank you all - this is a really cool community and I’ve learned a lot from lurking here!
I think there are two things going here, potentially:
If you set your location in VRM, then set the rates in the local timezone.
The VRM charts have been acting weird the past couple of days. I think there may be a bug somewhere. Is the system actually charging at the wrong times (assuming your rates are set in the local TZ)?
You can see on my chart below the “peak” prices are oscillating up and down (between yesterday’s peak rate and today’s peak rate) but in reality the rate is fixed. Once the time actually passes, then the line becomes solid and at the correct price.
@Barbara@jarco I’m guessing this is something you’re aware of, but it started occurring after the database outage a couple days back.
This is looking much better; if the timeline is plotted in GMT and not localtime then this is correct up to the 1600.
(My tariff is Day: 0800-2300, Night: 2300-0800 with special “EV Rate” 0200-0400)
On a related ask, I have ESS scheduled charging in place for 0200 for 7 hours. I had expected this would over-ride the DESS logic?
My original thinking was to be sure I get the batteries charged up overnight (our feed-in tariff encourages this) plus I have a Zappi EVSE running in same window and I wanted to block the battery from discharging somehow.
(I fully plan to buy Victron EVSE/EVCS once updated, fingers crossed it includes OCPP as needed for my employer! But that is another discussion entirely!)
