Thanks - I was hoping to get 48V 8 amp out of 4x100 wired series parallelI haven't personally seen any 100W 72 cell panels. You can wire two 12V in series to get 24V.
Just out of curiosity, why are you set on 48v from your array? That seems pretty specific.I was hoping to get 48V 8 amp out of 4x100 wired series parallel

Why do you want to wire 4 parallel?Thanks - I was hoping to get 48V 8 amp out of 4x100 wired series parallel
I am using nominal values and realize that 'my mileage will vary' when discussing panel voltages. I'm just spacing the system now and am interested in driving the highest reasonable voltage and lowest amps off the panels.Just out of curiosity, why are you set on 48v from your array?

Series parallel - for increased voltage and shade decoupling. I am using nominal values and realize that 'my mileage will vary' when discussing panel voltages.

24V panels are Not 24V output
12V panels are Not 12V output.
So called 12V 100 watt panels output about 18Vmp and 22Voc.
V x A = Watts
18Vmp x 5.5 Amp is 100 watts.
Just look at the label on the panel or the spec sheet and stop being confused by the 12V and 24V categories that are irrelevant when you use a MPPT SCC.
Voc
Vmp
Imp
Isc
So what charge controller are you planning on using?
This seems pretty spurious. What SCC are you planning on using? THIS should be more of a consideration than "reasonableness" of voltage of an array. The SCC's input voltage (and MPPT range), based on panel/array Voc (and temperature adjustments) should be your primary metric in selecting and configuring panels.I'm just spacing the system now and am interested in driving the highest reasonable voltage and lowest amps off the panels.
You have no idea what you are doing.Series parallel - for increased voltage and shade decoupling. I am using nominal values and realize that 'my mileage will vary' when discussing panel voltages.

Series is increasing voltage, same current.
Parallel is increasing current, same voltage.
Often the best combination is an array constructed of both. like 2S2P
I think you need to clarify your goals and system details for maximum benefit. A 24V panel is a 72 cell panel with the following typical parameters:
36V operating
47V maximum
On most MPPT charge controllers, you can't even put 3 in series.
Thanks - I don't have that area for one 400W panel - have to split into two.Trina 400W | SanTan Solar
