Advice on panel connections

[Byrogie]

I am getting 4 new 200 watt panels installed on my rv roof, and want to know best way to connect them, 2s2p for 43 volts or 4s gives me 86 volts if I’m calculating correctly. Is that too close to the 100 volt limit of my controller Epever Tracer 4210A? Pic of panel label below. Wire length 30-40 feet from farthest panel. Cheers

86V would be good down to about -15°C.

Parallel panels perform a little better in shading/partial shading situations. Top of an RV typically isn't a shade-free zone. I would go 2S2P. 30-40' at those lower amps isn't a big concern. 10awg will be fine at 40'

Perfect thx a lot. I will do the 2S2P
