Hi My battery is not charging when my solar is producing more than my house is using (battery at 60%) It charges fine from the grid, when power is cheap, but I was expecting it to use my excess solar poer to charge the battery. ESS is activated, and i have a MultiplusII 3000, cerbo gx, and 3phase…

YES … you have an “old” PV System with NO Communication to Victron … like Fronius … so you need this meter … configured and Position as PV on AC In … ET 112 for single Phase or ET 340 for 3 phase

As always, a little more information about the system would be helpful: What kind of battery system are you using? Have you activated DVCC? Is the battery BMS set as a battery monitor? Please include your “ESS Assistant” configuration. Where does the excess energy go? Into the grid? Or do you h…

Hi Steffen I am using A 14.33kwh battery connected to the gx modules using can-bus BMS LV. Excess energy goes to the grid. No DVCC is not activated. How can i include the ESS setup, is there an easy way. [image]

You can post the ESS settings via VE Configure … summary ESS configuration … Here, the voltages must also be adjusted to the battery system. However, DVCC should be activated … if possible … so that the voltage regulation of the MPPTs is also taken over by the system. Otherwise, it is possible tha…

I have a old Solaredge system 6kw inverter with 12 kwp panels. Grid meter: External meter SelfConsumption from battery : All system loads Multiphase regulation : Total of all phases Min SOC : 10% Active SOC limit : 10% Battery life state : Self consumption Limit charge power : off Limit inve…

Not sure where to find the ess summary.. [image]

take a look … [image] Charge with AC coupled PV, DESS mode-green DESS hi, i like to not feed the energy back to the grid from from my dc coupled pv’s but charge my battery with the extra energy. the enphase inverters are connected to the out1. and have a ET112…

Ah I see the system cannot figure out when the grid-meter is measuring negative, then i am producing to the grid, it need a seperate measurement from the pv system.

Thank you for the help. I think the newer SolarEdge inverters are running Modbus over TCP and can communicate this way. I have also installed home assistant, it could see my solaredge system by scanning the local network. Any luck I can use the same connection method.

There is definitely a way via Mqtt… [image] MQTT for AC-coupling on AC-In using an old StecaGrid 3600 PV Inverter Modifications Hi, I have a fairly fresh installation of MultiPlus-II (3P) and GobelPower Batteries running now quite well after my latest addion …

Yes, i also found that setting up a MQTT broker might be a way, but I can also see the system will be more robust, using a extra meter. I mifgt give the MQTT a try.
