I have an AC300 + B300 connected to 3 410 W solar panels. On the AC output I usually power some network stuff and a NAS drawing somewhere between 160 and 200 Watts. In this configuration, the PV input goes to the full 1200 Watt input.
During the summer on sunny days I connect more loads, raising the total AC output to around 400 Watts. With this increased load, the PV input appears to be limited to max 260 Watts.
Last summer, on an older firmware, I did not notice the behavior.
Has anyone else noticed this new behavior and know if this is intended?
I have a somehow similiar issue on my AC300 + 1x B300 system (EU version).
Asssuming two MPPT connected with PV.
While taking some more AC load the input volt of one MPPT is increasing by around 10V resulting in a drop of PV output watt. The second MPPT input/output seems to b stable.
By disabling this second MPPT from input volt the first MPPT is immediatelly going back to previous input volt resulting in higher output watt.
Any ideas? Any solution?
IOT v9014.12
ARM v4037.05
DSP v4036.07
BMS v1021.07
current obersavtion is that once AC output is somehow beyond 200-300W, the PV output is limited
If just one MPPT is working in the range of 260 W (independent which one)
If both MPPT are working each is getting ~125W.
If AC load goes below above level both MPPT produce again about 500W (which is the max solar power due to current conditions)
I hope to have that fixed with new firmware v4036.10 promised. @bluetti_care: I sent two direct message to you. Please confirm that these ones arrive.
I have similar issue as well. Recent purchased an AC300 and 3 batteries. I currently have 1200 watts of solar and when I use AC under load my PV watts drop from 900+ to 670 watts and remain capped at 670 until AC load drops.
Ich betreibe 2 Stück AC300 und beide zeigen das gleiche Verhalten! Normale Last sind zwischen 200 und 500 Watt alles normal. Doch wenn ich die Klimaanlagen dazu schalte, fällt die PV Ladung ab! Nach abschalten der AC Last steigt die PV Leistung wieder an.
