Separate charge/discharge rates?

Ifgow

Again I may have missed this (did check the FAQ this time 🤭), but is there a way of setting separate charge discharge rates? At the moment, I have the settings for battery at 1.5 kW (9.5 kW GE battery) in the advanced-battery rate setting, and the inverter at 3 kW, as I took this to be the max rating of the inverter. With these, my system seems to charge at 1.52 kW, but discharge at 1.42 kW, (the sliders in the GE app are both at 1.52 kW) and I’d like to balance them out or sometimes charge faster than discharge or vice versa).

Having different charge and discharge rate setting would be beneficial. A little while ago, Paul L (GivEnergy) installed the most up to date versions of the BMS/Gen 1 inverter firmware and now there is a significant different in battery charge rate and discharge rates due to “coding efficiencies” which result in a similar max charge of 2.42kwh but a now max discharge rate of nearly 2.9kwh for the battery that is supposedly only rated at 2.5kwh. So I can export approximately 20% faster than I can import with this “beta” software from Paul.
Consequence is for scheduled export, the window that WW is calculating/adjusting is often out and I hit the bottom % level often 10/15 minutes before the WW set window (even with the calculated adjustment).

Dai We'll have a look at that.

My battery inverter is only supposed to be 3.6kWh both ways, but I export nearer to 4.0kWh from the battery. Import is normal.

Gazzagreen your seeing 4kW DC battery power required to output 3.6kW AC power through the inverter.
