question

Go to settings/ESS and confirm what mode is set

Perhaps some more detail. What batteries?

Have you checked the BMS is configured in the GX system setup as the reference?

Is it sending parameters and details to the GX -> check the battery tab in the GX?

Details will show if charge/discharge is being blocked.

Is DVCC enabled?

If you drop grid supply does ESS start functioning ie charging/discharging?

I replaced the screenshot by a last-year overview that clearly shows that since july last year the battery stopped being involved in my power consumption.

I have flooded lead-acid cells so no BMS is involved. Further I never changed anything in the hardware setup.

I tried enabling or disabling DVCC without noticable differences.

If I drop grid supply the inverter jumps in. (I usually read about power outages in our neighbourhood in the paper some days later :-)

So,

conclusion:

The automatic filling system I got for free with the purchase of the batteries somehow failed and the batteries were completely boiled dry, in spite of my regularly connecting the reservoir with the water supply.

So refilled them with 60-odd liters of water and at first it stayed water, (sw 1.00) but a day later the batteries started boiling like hell, filling the shed with breath-taking toxic vapors while I desperately and in vain looked for a way to stop the charging process (which is non-existent on the solar charger).

The only way to stop it, seemed to be, disconnecting the solar panels which didn't look like a good idea, regarding the amounts of hydrogen gas that was produced.

Even switching off the easy solar seemed too risky (a spark is a spark).

I could in the menu set the charging current limit of the multi to zero and at least cut the current in half and I waited patiently for the sun to set, (at a safe distance from the shed :-)

Apparently some kind of miracle occurred. as the batteries started discharging and I had power all night without any grid usage. Next morning they were still al 68% according to the multi's SOC and now they are recharging when the sun appears, at a rather normal pace, 78% while I write this.

But nothing was wrong with the easy-solar
