About product

SolarEdge, Optimizer 400W, Add-On Box for one 60 or 72 cell modules, 8-60V, 11.75A, MC4-compatible In/Out, UL 1000VDC, P401

P401 also has access to the monitoring platform developed by the company to continuously upload performance data about the connected module, making maintenance an easier and cheaper process. The optimizers are attached via Zep Compatible screwless brackets.

Picked the units two days later at the nearest warehouse. Great feature! They are still waiting to be installed, but I have no reasons to doubt their quality, I’ve worked with them before
