SolarEdge 3.0kW Inverter SE-3000H-US000BEU4
After the purchase I thought that I should have taken a bigger one, since my system is around 4.5 kW. But it turned out alright. I talked with guys from a utility company, and they said it’s fine if the system is only slightly bigger than the size of the inverter. The inverter is really good! It was very easy to install and connect so I’m happy with the choice.

SolarEdge 3.0kW Inverter SE-3000H-US000BEU4
i loved the inverter! My system is small, more for house support than for standalone energy production so this is why I've chosen a smaller inverter. It doesn’t occupy much space and is quite good-looking. The production is outstanding: 99% efficiency is pretty good.

The system seemed a little complicated at first, but we found it hard to find good inverters for big-scale installation. This one is great and the complications aren’t actually real: it’s just three units instead of one. I think we made a good choice and thanks to a1solarstore for handling our order very professionally!

SolarEdge Inverter 11.4kW SE11400H-US000BNU4
Very happy with the inverter! Solaredge production is really good. Since I built a big system, I needed a sizable inverter and this is what I ended up choosing. It's good that installing it outside isn’t a big deal, like it is with some other ones.

Quite a special thing this inverter is. In my opinion, if you need an uninterrupted power supply, that’s for you. otherwise you’re better off with a standard grid-tie model

SolarEdge 100.0kW Primary Inverter SE100K-USRP0BNU4
We contacted A1 SolarStore half a year ago because we needed a new inverter for our system in Florida. This was the solution that they offered. The delivery was on time and the product arrived safely. The installation went smoothly. Honestly, after the installation we immediately forgot about it since everything was working smoothly. Now a1solarstore contacted us to ask how the inverter was doing (which is nice on their part) and I as a representative of our small business report that the inverter is great and the service was superb as well.

To me this is great. I actually needed an inverter that wouldn’t shut down with the grid, but instead would serve as a backup. here the blackouts are constant and super annoying. It’s small, but goes fine with my 5 kw solar.

SolarEdge P505 Power Optimizer 505W
I think it makes very little sense to use the optimizers without the SolarEdge inverter. Most of the benefits can only be reaped when you have both. I planned this setup from the very beginning, so it was not a problem for me. A1 has a great variety of both SolarEdge Inverters and power optimizers, which makes it possible to buy everything in one place.

SolarEdge P340 Power Optimizer 340W
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

SolarEdge P850 Power Optimizer 850W
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.

SolarEdge SE6000H-US000BNI4 6.0kW Inverter
I like solaredge inverters in general, and this is a very good model as well. The efficiency is good, it is small and light and enough for a small system. Too bad it doesn’t work with batteries.

SolarEdge Inverter 5.0Kw SE5000H-US000BNI4
I had a couple inverters before and their downside was always their software. Like, maybe production was good, but it was too difficult to manage. One of my inverters died after an update. solaredge app is very easy, self-evident, i’d say. I installed it, connected the inverter to my phone and basically instantly realised what was going on and how my panels are working. really love that aspect of solaredge of production

We’ve picked this model for our ranch and backed them up with some lithium batteries, because power lines here are quite weak. It’s very convenient and the inverter gives a good control over the system: i can watch how much was generated and how much was spent. good stuff.

SolarEdge Power optimizer DATASHEETP400-5NC4ARM

About product

SolarEdge, Optimizer 400W, Add-On Box for one 72 or 96 cell module, 8-80V, 10.1A, MC4-compatible In/Out, 47" PV wire, UL 1000VDC, P400

To achieve it, the device employs maximum power point tracking technology (MPPT). You can expect an increase of up to 25%, but the device can also cut your costs in other ways. For example, you can make maintenance more cost-effective by using the SolarEdge monitoring platform that keeps track of all your modules individually. The installation couldn’t be easier – just fasten a single bolt.

Compliance with all relevant standards

SolarEdge P400 is compliant with all standards for safety, material and electromagnetic compatibility. The model meets VDE-AR-E 2100-712 Fire Safety Standard, implementing rapid shutdown features.
