August 20, 20233 yr really i don't know why mppt is dropping power when battery fully and load stable even i have growatt and we know growatt design not different to much to voltronics and growatt's MPPT stable at all situations why this happens .its because algorithm of mppt is wrong or another issue?

At one point we speculated that the power supply board associated with the MPPT is actually causing glitches; some users found better results disconnecting that hardware! I don't know what the verdict is on that issue; users don't seem to be keen to do this, as there are side effects.
August 28, 20233 yr Author I tried putting capacitor on pv input like MPP solar said but that is not fixed dips .Actually this effect on output when Mppt disconnect for seconds and I can see that throughout light bulbs… I suspect that algorithm really is bad because using old algorithms to record Maximum power points during daylight day..
August 29, 20233 yr What main (U1) firmware are you using? Some firmwares had the bug that when the battery BMS says the battery is full, they shut down the solar charger (ignoring loads that could use solar power).
