How many separate mppt controllers can I connect to cerbo gx.? want to install 6, or more, large solar panels on my boat each with a separate MPPT. How do I connect them to the cerbo gx?
What is your battery voltage ?
If you intend to use one MPPT/panel, consider panel voltage being high enough to start the MPPT, usually Vbat+5v.
For connecting more MPPT’s to CerboGX, you can use the 3 built in VE.direct ports and add 1-2 VE.direct quadport from DuPPa.
If decide for VE.Can MPPT’s, the vehiculated number is 25.
24 volts.
What is the minimum panel voltage I need to start a mppt, such as the 75v 15 amp unit?
Thank you for the solution you mentioned. Is there also a way to use a usb hub and connecting the the usb connection on the Garbo gx?
I see that you already answered the first part. So min 29 volts for panel.
I have four of the 75/15 tied to our Cerbo using Victron ve.direct - USB cables to a cheap 4-1 USB splitter cable. I recall the ve.direct max device limit on the Cerbo is somewhere around 15 units, check the manual
