Rooftop Commercial Project - SolarEdge P680 Optimizer vs SolarEdge P730 or P850 Optimizer
Why should I use a SolarEdge P860 optimizer on a rooftop commercial project instead of a P730 or P850 optimizer?
The primary difference is that the P730 and P850 only offer a single input for two modules which therefore must be connected in series.

SolarEdge’s solution is the P860, which features dual inputs for independently connected modules. Connection in this manner is compliant with 2017 NEC requirements and circumvents the issue seen with the P730 and P850 series optimizers. If your jurisdiction is still under 2014 NEC requirements, you may still be able to use the P730 or P850 – always check with your AHJ/utility before proceeding.
