gwynnej3 I think I've mentioned this previously, but if your on IOG with fixed export, it makes no financial sense to undercharge your batteries. Just set them to always charge to 100%, then all solar not self consumed gets exported at 15p/kWh.
If you want to finesse things further for more profit, you can dump any excess left in your batteries at the end of the day, and/or set your batteries to not use solar.
