max pv array voltage for SPD115

[ultraschall81]

Hi!

If I have Vmmp 36V or 72V should I use the SPD115 or, as always adviced the SPD300?

Thanks

Well if the VMP where going to be always 36vdc I would say you could use the SPD115 but the 72v would be to close open circuit. For my money I would go with the SPD300's all around
