Hello,i have 4 550 boards connected to a mppt 150/45
They are oriented to the west with a good inclination, I think they should produce more than what the installer tells me, it does not exceed 1370W.
can it be, is the mppt small?
asked
is the mppt small?
i have 5 Pylontech US3000C 48V
The 45 in the model number is output current at battery voltage.
On a 48V system charging at 52V, you should see output around the panel max with this MPPT. The MPPT will handle about 2500W on a 48V system.
BUT.... It's dependant on illumination, shading, panel temperature and resistance in cabling.
If you have the batteries and MPPT linked to a GX device, the batteries will control the current.
