Minimum voltage for MPPT

b6f37553-403a-4d5d-a2c1-0af6dffd942e.jpegI’m slightly concerned that i may have miscalculated.

I have 2 panels, one at 111W, and one at 21W which need to be individually linked to their own Victron 75/10 MPPT.

I‘ve noticed that the 111W one in particular has quite low published voltages vis the 5V differential required to initiate charging.

WIll the MPPT work to charge a 200Ah 12V Victron LiFePO4 battery?

yes it works, a full lifepo has around 13,5V . without charging your first panel has 21v, enough difference to begin charging for mppt
