This is different to nominal voltage. Typically a 12V panel would have a max power voltage around 18V, while a 24V panel would be between 30V-36V. The same rules apply as above depending on whether your panels are in series or parallel. This is the voltage that your batteries will be charged at.
alright. on a voltage drop only stand point, it would seem that using two 36V panels rated at 5.5A each, wired in series will keep the amps at 5.5, and ramp the voltage to 72V, which my MPPT can handle.
Ultimately you just need to make more voltage than 14.4v, so either style panel will work. With the Victron 100/30 you will be able to run your panels in parallel or series, so get the less expensive option? With MPPT, you don't really care about the "voltage" of the panels, meaning you don't care if it's a 12v or 24v panel.
Individual solar panels will usually have a nominal voltage of 12V or 24V. If you are connecting them in parallel they'll stay at the same nominal voltage, if they are connected in series the voltage will increase. (Not sure which? See our post on Series and Parallel) This is different to nominal voltage.
Add a fourth panel, and you’re still within the voltage range. We can also combine two 24V panels in series. One 24V panel will output around 36V, so two would output about 72 volts. That works, because it’s within the 40-100V range. How do we get close to the 1000W limit though?
First, gather the following specifications from your solar panels and batteries: Individual solar panels will usually have a nominal voltage of 12V or 24V. If you are connecting them in parallel they'll stay at the same nominal voltage, if they are connected in series the voltage will increase.

Using a charge controller with an all-in-one power station
"Yes if you plug the solar panel in the small round DC jack then the solar panel voltage is 12-30v, so your 18v solar panel can be plugged in the DC input jack." So although I only mentioned 18V support seems to say anything up to 30V is fine however, if 30V is okay I can''t see why they wouldn''t mention this in the product manual or website.

Charge 18V (20V) Lithium Battery Without a Charger [Avoid This]
The basic science of charging an 18V Lithium battery is to provide the 18-20V DC voltage at both terminals by connecting the voltage source''s positive terminal with the 18V Lithium battery''s positive terminal and the voltage source''s negative terminal, the negative terminal of the 18V Lithium battery.

So what''s the difference between 12V and 18V solar panels?
And since the battery was 12V it was easy to think of the panel as also being 12V. The true maximum power point of these panels (and most modern 12V panels) is close to 18V and thus should be considered 18V panels not 12V. Also, most panels advertised as 24V are really two 18V panels in series with an open-circuit voltage well above 40V.

which panel to choose, 18V or 36V? | DIY Solar Power Forum
30A into a 12V discharged battery is 360W. You have 400W of panels, but that''s fine because they''ll rarely deliver more than 360W. Even if they do, the MPPT will ignore power over what it wants, will limit its output to 30A. Looks like a good fit. A 40A fuse or breaker would be good between battery and charge controller.
