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 energy meter installed. I am new to the victron world, so any help would be apreciated. /Karsten ---

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 have other DC loads? ---

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](https://europe1.discourse-cdn.com/victron/original/3X/5/1/51f6778083335ef933ef731540075b4282fffe12.png) ---

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 that your charging voltage will not be adjusted. DC surplus feed-in is surely activated? By the way … it looks like a 3 phase Ess System ? ![grafik](https://europe1.discourse-cdn.com/victron/original/3X/8/6/86c51a808d5435cc86db263160a42f8fc81fd3b5.jpeg) no Mppts on the DC Side ? no DVCC necessary Solar on the AC Side ? ---

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. ---

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 ---

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… > [@MQTT for AC-coupling on AC-In using an old StecaGrid 3600 PV Inverter](https://community.victronenergy.com/t/mqtt-for-ac-coupling-on-ac-in-using-an-old-stecagrid-3600-pv-inverter/877): > > Hi, I have a fairly fresh installation of MultiPlus-II (3P) and GobelPower Batteries running now quite well after my latest addion of a VM-3P75CT as a grid meter.

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. ---

Yes does the Multiplus need to know in the setup ? ---

The Multi does not need any information for this… with a single-phase ESS, the Multi MUST always be on L1 of the meter BUT the separate meter for the PV on AC In is also used for the graphical display in the console and the VRM It “could” be that you can achieve something with the correct settings in the “Charger” section in VE Configure AND by deactivating the AC PV feed-in … this is just a guess, as the system already recognizes that you are feeding in … The voltage in the “Charger” section of VE Configure MUST be high enough to charge the batteries… i.e., higher than the voltage “at the moment.” Give it a try… ---

Just a remark I did not buy a meter yet, but setting the sales price to 0 had the effect i was looking for, at least for now. The system charges my battery instead of trying to sell to the grid. [Next page](https://community.victronenergy.com/t/ess-no-charge-when-solar-is-producing/48755.md?page=2)
