NEED a Financial Wizard to give me some advice.

I have a MP2 with ATM 20kWh of US5000 batteries soon to be 30kWh

I am now on Octopus iGO tariff which apart from the guaranteed 6 hours of Low Cost Energy for charging my EV seem to be giving me a lot of Low Cost Energy during the day and later on in the evening.

SO I am wondering should I limit my battery charging to say Minimum SOC 20% and Max SOC 80/90% and use the low cost energy to run the{ much smaller energy wise} house loads rather than use that energy to charge my batteries from 5% to 100% SOC AND charge my batteries overnight on the Low Cost EV six hour schedule, plus any extra overnight Low Cost Energy that Octopus are scheduling.

Obviously when my solar is producing energy above the house loads then that is {expensively installed} free energy.

Thoughts and advice?

Thanks

Check out Dynamic Energy Storage System (DESS).
There are some complaints about it, but in general the free Victron system is optimzing and automating all of this for you.

It will take into account

  • consumption forcast
  • PV forecast
  • system efficiency
  • your hourly grid rates
  • battery cicle costs
  • min SOC (until grid failes)
  • battery health

Than it will calculate and keep updating the optimal charfing plan.
