Hi there,
I'm using a Quattro 48/15000/200-2x100 with two BYD Premium LV batteries with ~31kWh of capacity. The Quattro is connected to the grid only (no other connections used).
With ESS in External Control and the system set to charge, the system does exactly what it is told to do (e.g. 5000 or 8000W).
If I tell it to discharge at a set rate (i.e., back-feed in to the grid), it works at small numbers (e.g., -1000W or -2000W etc) but if you put a bigger number in it never achieves it. As an example, with a target of -8000W set, the system seems to cap itself at approximately 2600-3000W or about 55-65A discharge from the batteries.
The BMS is reporting to my GX that the discharge limit is 432.0A, so that doesn't seem to be the issue...
Any ideas?
Thanks!
