Hi,
This week I had an AIO and gateway installed. I’m looking to maximise use of the battery’s capacity whilst minimising degradation.
For info, I have existing PV and an EV charger. I’m on Octopus Intelligent Go.
I’m planning to export unused capacity each day prior to the cheap overnight window.
- OK to regularly charge to 100%? Whilst I wouldn’t do this in my car unless needed I can see that the actual capacity of the cells is 15.97 kWh so “100%” is really only 85%.
- OK to regularly discharge down to 5%? The minimum in app/portal/API s 4% but a thread on here suggests GivEnergy recommend changing that to 5%. I could set it higher for export purposes (e.g. 10%) if it’s going to have a meaningful impact on long-term battery health.
- Max charge rate - Default is the max of 6 kW. Wondering if pulling this down so it takes the whole 5hr overnight charging slot would help battery health or reduce charging losses.
- Max discharge rate (for export) - Default is the max of 6 kW. Similar to 3) I could bring this right down if it would give lower losses or support health.
Thanks for any insight.
Paul
