About product

SolarEdge, Optimizer 340W, Add-On Box for one 60 or 72 cell modules, 8-48V, 11A, MC4-compatible In/Out, P340

SolarEdge P340 is meant to replace the usual solar junction box. Each power optimizer connects to only one solar panel to maximize its performance. This goal is achieved using maximum power point tracking technology (MPPT). You can expect an increase of up to 25%, but the device can also save you money in other ways. For instance, you can lower maintenance costs by using a specialised monitoring platform that keeps track of all your panels individually. SolarEdge made the installation as easy as possible – all it takes is just one bolt.

Compliance with all relevant standards

SolarEdge P340 is compliant with all standards for safety, material and electromagnetic compatibility. The model meets VDE-AR-E 2100-712 Fire Safety Standard, implementing features for rapid shutdown.

I could’ve gotten these a couple of years ago, but my installer talked me out of it, saying the more elements my system has the more likely it is to fail. But the benefits outweighed the doubts. 25 year warranty really helped

I’ve entertained the idea of getting power optimizers for a while. My indecision came to an end after I finally did the math to see if it actually will be profitable. The P340 is worth every cent.

I must say that I didn’t see the maximum performance boost possible, I’d say 15-17% only, but I get that it depends on your circumstances. Overall, this is a great product that does everything promised by the manufacturer and even more.

Hi! I already have some SolarEdge optimizers, can I use them all together?

Unfortunately, no. Mixing different models in one string isn’t allowed by the manufacturer.
