I am sure this has been answered in the past - I have done a search - sorry.
We are briefly (a few weeks) between TOU tariffs so no cheap night time battery charging.
At this time of year there will not be any surplus generation going into the batteries. Without intervention they will just be looked after by the inverter at minimum SOC.
Is this ok or should I be giving them some grid charge?
Thanks

could try running winter battery conditioning
If your batteries are idle and empty it shouldn’t cause a problem because if the battery SoC does drop below 4% then they will automatically charge themselves up a bit to prevent damage.
Having said that, in general its better to exercise the batteries than to keep them empty for long periods of time, so maybe do a force charge for a bit every 4 or 5 days. No real need to fill them up entirely, just charge a bit and let them discharge. If you are getting reasonable solar generation then that’d be happening anyway

Thanks. Your last sentence does not apply today but we can hope!
If the batteries are not to be used (charge or discharge for a period of time, I'd charge them up to about 40% and turn ECO off.
When stored before sale, around 40% is the sort of charge level used, and is good for months.
