A solar panel that comes the mind is the LG NeON 2, these panels have a Vmp of 41 Volts. If you parallel 3 of these panels you should max the unit out. You can also try to get like 6 12V-200W solar panels from Renogy. These panels are rated at 19.2 Volts for their Vmp, so if you connect them in a 2S3P configuration, they should max out the f3800.
Therefore, when choosing solar panels for your solar generator, you should keep a few things in mind, like the solar panel''s output specs and the solar generator''s input specs. Moreover, it''s essential to consider the size and weight of the panels. Larger panels will generate more power, but they will also take up more space.

Dividing the power in watts by the voltage will give you the current in amps, which is the sizing parameter for your MPPT charge controller. You can also determine this value based on the size of your solar panels.For example, six 200 watt panels would provide 1,200 watts total, which could be divided by 12 volts to give 100 amps.
How do I size my battery bank and why is it important? It''s very important to properly size your deep cycle battery bank. The amount of battery storage you need is based on your energy usage. Energy usage is measured in kilowatt hours. For example, if you need 500 watts for 8 hours per day, then your energy usage is 4kWh per day.
The battery size determines what solar array size can be used with the controller. The higher the battery voltage, the more solar panels you can use. Charge controller amps x battery voltage = solar panel size in watts. 30A x 12V = 360. 30A x 24V = 720. Again this should only be done if the controller VOC is not exceeded.
