Temperature derating #187

It would be nice to limit charge/discharge power based on the battery temperature, e.g. ramping the power from the stated BMS power capacity at 40 degrees C to 0 W at 50 degrees C. Similarly at low temperature, ramp from BMS max power at -10 and 0 W at -20

I have a similar wish regarding the temperature rating or reduced power related to temperatures below 20 degC. Using Goodwe 30 kW inverter with simulated 2*BYD HVM batteries. Ideal would be if the temperature could be "translated" to 21 degC when in the range of -10 to 19,9 degC ? This would allow us to run full power when needed. Without having to heat the batteries at all times.
