Thank you for sharing the information.

I’ve changed my DOD to 80% on grid and to 90% off grid. This seems to have resolved my issue. Still not sure why my batteries switched off at 90% DOD on grid considering the batteries can go to 95% DOD.

Thank you

No I don't have batterview.exe. I'll search around on the web and see what info I can get.

Just to make sure. Do I set the “battery activated” to on or leave it off?

I am going to try that and set the DoD to 79% and see what happens. Strangely, yesterday morning at 11am the DoD of 89% was also reached and the batteries did not switch off. Instead it was in standby mode for about 30 minutes until the load subsided and started to charge again.

So I tested the scenario again and my batteries switched off last night when the 89% DOD was reached. I had to manually switch on the batteries this morning. This is frustrating. If I go away for a weekend and as things stand my batteries won’t charge.

I also noticed that when I have "battery activated" ( in advanced setting (PV Master app)) set too on it will after a few hours show as off again. The inverter makes as click noise as it should for the changes to take effect so I know it accepted the changes. Could this not be part of the reason that my "battery activated" is always off while it should be on?

Thanks Tinuva. I'll try the 85% DoD but I have feeling no matter what DoD I set it it will do the same. My BMS is working good and besides for the DoD hiccup there is always a "normal" BMS status between the inverter and the batteries. I am still looking on the internet for possible reasons.

My Goodwe 4850ES inverter has been installed about a month ago. I have 2 us3000c pylontech batteries connected and 10 x JA Solar 385W Mono MBB Percium Half-Cell panels. All is working exceptionally good for us expect when the DOD is reached. It is set at 90%. Normally we do not reach the DOD because our batteries have about 25% left before there is enough sun in the morning to charge the batteries again. The problem comes when the previous day was cloudy and rainy and the batteries only charges to about 55%. During the early morning hours when the 90% DOD is reached the batteries switch off. It used to be in standby mode but not lately. Now it switches off and nothing happens until I manually switch on the red button (sv switch) on the batteries. I haven't changed setting except once when testing the "economy mode" in relation to general mode. Currently I am in general mode. Any advice as why the batteries switches off and does not go in standby mode?
