So you can export at 15p in the day and dump double the kWh (at 7.5p) into your storage heaters at night.

Well, I'm running my first test to see if the Goodwe Hybrid inverter responds to its own SOC limits to stop discharging.
Lessons learned so far.
1. The solar iboost would have to be off while discharging.
2. When running a test like this on a day like this the Victron system has to be shutdown, otherwise we'll never get down to 85% SOC on a 3.6kW discharge limit.
3. Time to get the calculator out!
