EG4 6000XP Battery Eco Mode Question

[senoird]

With the shorter days now and sun at lower angle, which is now causing some shading in the late day Im thinking about switching to battery eco mode. The question is if I do eco (Grid Charging is off) when the batteries hit EOD and the inverters (2 paralleled) go into bypass is there a setting to increase the 10% SOC increase before the inverters switch back to batteries? Im seeing it charge from 20% to ~30% then switch back and burn them down to 20% in a few hours (AC still running this late in the year). Keeping them that low seems to cause me grief with SOC drift then I have to switch over to Voltage charging for a few days to correct that. Id like to just stay in bypass until they charge up to 90% then go to battery mode, even if that takes a week with all the rain we are getting. Also if there is a way do I only have to set it on the master or on both?

I can't answer your ECO question as I don't use it. Do you have the "6000XP working modes Quickly settings.pdf"? The answer you seek maybe there. Available on EG4's website. The master inverter propagates the settings to the slaves.

Maybe try to set grid priority during specific times during the day to keep SOC levels at manageable levels of.. Then adjust seasonally as PV production increases..

If you’re using solar assistant, then you can do something similar with automations.

You can accomplish what you want by making sure you have enough solar to power loads and charge batteries. It would use the batteries if solar was not enough to power loads. You can also set AC charge and set the SOC.

I think you are misunderstanding the question.

I think OP is asking if the 10% threshold can be changed. Can we run down to 20% SOC and then NOT start battery discharge again until 90% SOC.

The answer is NO.

Using Solar Assistant for automation is likely the easiest way to do this.
