Hey friends,
I’m currently looking for suggestions on which Victron MPPT to get in terms of size and options, this will all be installed in my fifth wheel toy hauler.
what I have so far:
16 280ah LFP batteries, will be 24v
Batrium BMS
Victron Cerbo GX
next items to purchase:
4 405w solar panels
victron MPPT
im still on the fence on whether I’ll go all 4 in series or a series parallel with 2 each, I know that will play into the size as well. I think series is best of both worlds in case I encounter shade.
can anyone help me understand if I want/need one of their MPPT’s with the VE.CAN option? Only certain sizes offer that I believe.
thoughts on terminals or MC4 connectors on the MPPT?
can I temporarily wire the battery bank for 12v and still use the same MPPT, even if it’s not as efficient?
if I wire my panels in series parallel I believe Victron’s site recommended the smartsolar 150/70
i don’t plan to ever expand to more than 4 panels.
here are the specs of the panels I’m looking at:
405w
Vmpp - 41
Impp - 9.89
Voc- 49.4
Isc - 10.51
thank you all!
