Hello,
I would appreciate assistance in this as well. I am submitting a proposal today and I'm up against a Quattro vs my 2 x Multiplus 2 on a single phase.
ie: 1 x Quattro 48/10000 vs 2 x Multi 48/5000
If someone could urgently assist be with this I would be eternally grateful.
I see the first answer is roughly 10 months ago.
EDIT: Please note - this same question was asked 10 months ago and I posted there as well today. Due to my questions being more specific - I've created a new thread.
Question 1
Does the Quattro 48/10000 still NOT have anti islanding? The thread last year was answered no.
If Not, then to comply with our regulations - how do I deal with the anti islanding
Question 2
a.Are the Multi's not connected in parallel? OR
b. Must I split my DB in 2 - One Multi out (AC1/AC2) to one half (of the) DB, and other Multi out (AC1/AC2) to other half (of the) DB
As mentioned in the other thread - It seems as if the loads must be split
Question 3
a. How do I then deal with the batteries - Are they on the same bus as BOTH Multi's and the Battery?
Should one Multi be off or disconnected - that all the battery power then gets distributed to the remaining Multi.
b. There is a new UP5000 Pylontech out - Can I accept that this will also be compatible with Victron
Question 4
I read a while back that the Multis must be from the original "batch" / Firmware if used in the same install. What happens if one has to be replaced? A previous reply was that Victron would then replace both - Is this indeed the case?
I am using two SEPARATE arrays
first array goes to one x MPPT 250/85
second array goes to the second MPPT 250/85
My intention is, is to take each array to a separate combiner box BUT to then take each combiner box to ONE BUS - In this instance probably one to the first multi and the second to the other multi - being that they are connected in parrallel and on the same bus anyway. and, for enough space for the lugs (not too many on one bolt)
