I have the following setup: Quattro 48/10000/140-2x100, Cerbo GX, 3 x 150/100 MPPT each wired with strings of 3 panels totalling 13,000watts, LV-Hub with a variety of Pylontech Batteries Modules of which all 15 are online (total installed capacity per Cerbo GX = 896Ah.
My MPPT's pick up and it seems when it reached +-8,000watts output all 3 MPPT's drop off to zero and immediatly start picking up again. If have manually disconnected strings of panels from the MPPT's and if the total yield stays below 8,000watts all is good. As soon as it reaches 8,000watts it drops and immediatly picks up. No error codes. The 8,000watts yield can be from different MPPT's or just one with say 4,500watts + a second with 4,500 watts it seems to be the 8,000watts limit.
Setting charge limits to amps that equate to just below 8,000watts (example 140Ah) or even less does not seem to resolve the matter.
The yield of 8,000watts are also not dedicated to charging the batteries. Its used to cover the load first which run around 4,000watts average during the day. only whats left goes to batteries which is not near 148Ah.
Charging the batteries from utility at 148Ah as dictated by the Pylontech BMS have no problem so its not the batteries refusing the charge.
Anybody with any idea what could cause this?
