they are actually set up in 12P (3 groups of 4) to stay under the 100v 40a limit of the Rover.

If I understand correctly, the Rover is set for 24v, Li battery. No adjustment can be made unless battery is set to “user”. The panels are providing around 70v @ 8a depending on irradiance. The rover is limited to 100v.

I have no complaints with them. I have not checked their performance that closely, but they have performed well. My thought is that for the cost they are a bargain. If they do underperform, it's nothing to add 1 or 2 more to the array. Mine are for a "secondary" shop/ outbuilding.

I have been using 6 100w Renogy panels with my 40A Renogy Rover to charge a 280Ah 8s 24v battery and a Giandel 4000w inverter, and they aren't getting the job done. I have acquired some Stion STL-145 (79 VOC 2.6ish A) and was wondering if over paneling is possible, and just how much over...

Nothing on the load ports. I'll change the settings and post results.

Happy New Year everyone, I need a bit of guidance on settings for an off grid shop system. My equipment is a Rover 40amp SCC, 8 EVE LF280k in series for 24v using Xiaoxiang BMS, and a Giandel 4000w 24v inverter. I have 12 Stion STL-145 panels in 4P3S configuration for power. The cells were top...

Thanks for the clarification I found a good deal on the Stion panels from a large solar farm being disassembled ($.42/W delivered to my location), so I will look at multiple parts/directions. How could/would I configure the Renogy 100W (22V 5A) and Stion 145W (76ish V 2.6A) panels together to...

I'm not exactly sure. Have seen so much confusing information about settings. Noob ignorance.
