First time posting.
Got a quote for 18x Longi LR4-60HPH-370M panels, SolarEdge P370 DC Optimizers and SolarEdge 5000h Inverter. Seems reasonable products.
From a pairing point of view though, 370watt panels and 370watt optimisers seem to make sense. But from a longevity, buffer, headroom point of view is there any advantage in pairing higher rated DC Optimizers such as P401 or higher ?
I’m looking at:
and trying to wrap my head around the current specs.
Longi Panel states 10.76 Max current with a short circuit at 11.52
P370 DC Optimizer state Max short circuit current as 11 and the P401 is 11.75.
Should I be asking for P404’s (or higher) with the 370w Longi’s or just stick with the P370’s ?
