I have installed the smartsolar 100/30 and installed 2x 200 Watt 36 Volt panels in serial.
WIth the test I see on one panel connected. a voltage off 47,47 volt and in parallel dubbel so around 95 Volt. I charge 2x 100 A/h AGM in parallel.
Question is now is this the best solution.because of the high voltage, and should I move to 2x parallel configuration? Picture attached from the panel and screenshot during testing with 1 panel connected.
Thanks for your idea's about this,
@Jollyhobby given the Voc will only increase with lower panel temperatures, and you observed 47.47v, it is a sound idea to run those 2 panels in parallel. No problems charging a 12 or 24v battery.
Just need to use thicker cables for the doubling of array current.
As you are using a 12V System, I would recommend to change the Solarpanels in a parallel configuration. The benefit is, that every solar panel is then working "individually". And additionally it seem, that in cold conditions the voltage of these solar panels in series might reach more than 100V what would destroy you MPPT charger.
