SolarEdge P800 and P850 Optimizer Name Change Explained



SolarEdge has recently updated the naming of its optimizers, with the previous “P800” updated to be named as “P850”.



Why the change?


SolarEdge reevaluated the power capabilities of the P800s and found that they can manage higher power than they were previously certified. This evaluation regarding power capabilities is true for all previously manufactured P800s as well.


The P800s product name has been replaced with the P850 product name, but during inventory transition orders for the P850 may be fulfilled with products labeled as P800s. SolarEdge has put out a letter certifying that these devices are functionally exactly the same, despite the name difference.
