About product

SolarEdge, Optimizer 850W, Add-On Box for two modules, 12.5-105V, 12.5A,  3-Ph 9kW to 33.3kW inverters only, MC4-compatible In/Out, UL 1000VDC, P850

With SolarEdge P850 traditional junction boxes are a thing of the past. These power optimizers are used with one or two PV modules. Connection is a breeze thanks to a single bolt arrangement. You can also find panels with embedded units that have been pre-installed by the manufacturers. The owner gains considerable advantages from this alliance. Among them, a performance boost of up to 25% and lower maintenance costs. A power increase is mainly the result of maximum power point tracking technology (MPPT), while lower maintenance costs can be attributed to a sophisticated monitoring platform that constantly tracks all your panels one by one.

I’ve bought various items from A1 Solar store, the service is invariably great. I use P850 with Solaredge inverters for their higher efficiency and tracking features. As soon as SolarEdge starts selling their batteries, I’ll be the first in the line to get one.

One of my favorite features is the monitoring app. We never knew it could be so important until we tried. We saw how we used our power and it changed our habits.

We bought these to deal with the shading issues that seriously affected the performance. Very happy with the purchase and the results we got. Can recommend to the people who have similar problems

I see that it is connected to two panels at once, can I still track them individually?

No, P850 only offers single input for connected modules.
