Hi!
I’m a new user for two months now. The system contains:
3x multiplusII 3000
1x smartsolar mppt RS 450/100
cerbo GX
4x pylontech us5000
it been doing great and I’m very happy with the system overall.
I can’t help noticing some weird things that the system does, most of it is software related or my own? I’m curious if you are experiencing the same…
most of the time I have My system set on ESS, because the dynamics of DESS has some weird habits.
-
when the price is at its highest, it will discharge accordingly but till a certain point it had forecasted. for example: 09:00 till 10:00 price is highest → battery will discharge to 50% the price is second highest from 10:00 till 11:00 it will discharge to 15%.
if the SOC is met at 09:50 it will just sit idle for 10 expensive minutes only to continue 10 minutes later for a lower rate, just because the forecast was achieved. -
also when I set my maximum charge rate in: settings → Dynamic ESS->battery-> edit-> to a certain value, lets say my max is 7kW and I set it to 2kW to prevent the system working so hard and just let it charge slowly over time. It will completely iognore those values and just charge at the previous rate?
When going into remote console->settings->DVCC->limit charge and set it to the desired Amps it WILL comply and charge at those rates. -
some things in the software are just a bit off. Why do I have to go all the way into the settings-> Dynamic ESS → System → edit → to chose between trade and solar? This can easily be a switch in the dashboard.

why is there no custom profile whether you can choose when and how much you buy/sell. Manual ESS, I am bound to what the system is forecasting on what to do.
Maybe I want to discharge 50% on 10:00 but this is no possibility. I can not dicharge the battery manualy.
for charging manualy I just turn off DESS and increase minimum SOC
do you also have some weird things you can’t get your head arround?
