(5) 365w panels 70.56 voc 58.8 vmp - let's talk about efficiencies and MPPT

[PetePetePete]

All 5 panels are on the same plane.
The battery is 48v (51.2v)
Using Victron, what are you think is the best combo for efficiencies (maximizing wattage).

Power 365

Voc 70.56

Isc 6.83

Vmpp 58.8

Impp 6.21



(5) Individual MPPT? (The Victron Calc says I can't do this, but... I'm not sure that's true)
(2) BlueSolar MPPT 250/70-Tr VE.Can (3 on one and 2 on one)

Let's hear from you smart people.

I use the Victron MPPT calculator.

I used it an it said the two BlueSolar MPPT 250/70-Tr VE.Can...

Not that I want to do it, but is there a Victron MPPT that will do ONE of these pannels (so I have 5 MPPT) (one for each panel)?

Best i see is a pair of these: 3P and 2P

How do you see 100v unit for 2 and/or 3 70v panels?

How do you see 100v unit for 2 and/or 3 70v panels?

Panels in parallel, that it. 3 panel in parallel will give just over 1000W and this is the perfect fit at 20A to a 52-53V battery.
Still, MPPT 100/20 can consume 0.030-0.090 kWh / day each, so is it the best in term of efficiency?

Why does the Victron calculator say that the 100/20 MPPT won't work with a single one of these panels?

Don't know, but it will work well as mine work well with 76Voc, 63 Vmp and 45A* at input charging a 16S LFP battery.

*panels could give 45A, but they are limited to approx. 15A as MPPT can't give over 20A to battery.
