Multiplus II 32A + SMA Sunny BOY 3600tl-20 + mppt + 20kwh Lipo4
Advice to connect the parts all?
1- I was thinking of connecting the SMA in ac coupling
om multiplus II with
some 8 panels of 280w;
2-8 direct panels to batteries by mppt
Thanks for your suggestions
thank you
It is possible to have both AC coupled and MPPT at the same time if you want.
If you have a choice of one or the other, then MPPT would be better than AC coupling.
If you decide to do AC coupling, there are two more choices, Grid Parallel (AC-IN) or Grid In-Line (AC-OUT)?
With Grid In-Line your Sunny Boy will be having 2240Wp? This will be below the 1:1 rule, so OK for the MultiPlus II. With this topology, MultiPlus II will keep the Sunny Boy working if the grid fails.
Hi,
1. How MPPT connection is made?
2. In the case of AC-coupling (Grid Parallel type) how can I charge the batteries only from solar? How can I discharge them only when there is not enough solar power?
thank you
Thank you for your help
From what I've read, my fr3s can not do ac-couplig. Right?
I think of coupling the Sunnyboy 3600TL-20 with the AC-OUT to control the power per frequency, but I am limited to 2400w with the multiplus 3000 II in case of power failure at night, because if I can only use 2400w of multiplus + the power of the SMA. Right?
Is there an advantage in doing AC-coupling with the Frontos symo (for example) in relation to the SMA 3600tl (or other)?
what is the maximum power that can go through the "Critical Charges" in multiplus II?
I know that without the presence of the network I can only inject with the inverter 2400w.
Basically I wanted to know if it's possible to "load" the whole house (32A) into ACin
Explaining .... if you have contracted from network 32A of the network,
can I pass this entire chain through the multiplus II before entering the house distribution board?
Obrigado
