Look at the panel voltage and amp specs. So called 12 volt 100 watt panels are about 21 Volt open circuit and 18 volt working output. Two 21 Volt open circuit panels connected in series are about 43 volts. The 24 volt all in one units have a MPPT controller with a max 145? Volts open circuit input and a working voltage range.
In the specs for the solar panels, you should look for the voltage temperature coefficient. The VOC voltage is at 25C. As the panels get colder the voltage will rise. My panel increase by 0.3% per degree C colder. At 0C, that is a 7.5% increase. 36.8 volts x 1.075 = 39.56 volts. Keep in mind your voltage drop at 400V working voltage is over
Can the feed for the solar panels be split at the inverter to use 2 MPPT? I''ve got to run around 100 feet, so would like to do it in one set of wires.

Built-in 4A high-efficiency MOSFET switch, making the efficiency up to 94%.
Panel temperature will affect voltage – as has been discussed in another blog. Have a look at these I-V (Current vs Voltage) and P-V (Power vs Voltage) charts for a 305W solar panel from Trina Solar. You can see in the P-V curve that as the solar radiation decreases from 1000W/m2 to 200W/m2, the power drops proportionally – from 300W to 60W.
For a 5 AH sealed battery you need to be able to get at least 500 ma from the panel at 14 volts. Since the maximum power voltage of the panel is probably around 20 volts, you would need at least a 10 watt panel to give you that. It is also possible that the CC you are using just cannot work properly with that low a current.
Renogy''s 100W 12V N-Type Solar Panels are designed with an open-circuit voltage of less than 25V, making them compatible with 99% of MPPT and PWM charge controllers. The "12V" here does not refer to the voltage of this solar panel (VOC or VMP), but to the fact that one xxxW solar panel is suitable for 12V system (i.e. a 12V battery

Generally, the nominal voltage of any solar panel is 12V or 24V. This is the voltage at which normally DC appliances operate, batteries are charged, etc. However, the nominal voltage could be 20V or 18V as well. The
Nominal solar panel voltage is important when you are using a PWM solar controller, because the nominal voltage of the panel and battery should match. This means that for every degree the panel cell temperature rises, the panel produces 0.37% less voltage. Working out the change in Voc can be important if your solar array is close to the
A solar panel is a current source with an upper voltage limit The current that the panel will produce is linearly proportional to the solar illumination. If a panel will output 8A when illuminated with 1,000W/m² it would output about 4A when illuminated with 500W/m², 2.5A @ 250W/m² etc...
