SolarEdge SE7600H-USMNBBL14 7.6 kW Inverter

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.

We’ve just finished the installation of our solar system with this inverter. I paired it with Panasonic panels. The system is tiny, but so far the performance is amazing!

06/09/2024

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.

SolarEdge 43.2 kW Three Phase Inverter SE43.2K-US02IBNZ4

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.

SolarEdge Inverter 3.0kW SE3000H-USS3BBC14

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.

SolarEdge Inverter 3.0kW SE3000H-USS3BBC14

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-USS3BBC14 6.0kW Inverter

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

morgen

06/29/2021

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.

how do you control it? Do you have to always go to the garage or else place to adjust the settings?

A1 SolarStore

No, you can control the inverter remotely. It can be connected to your devices via Ethernet or Wireless

Andrew

08/16/2021

ay. I’m looking for an inverter that is going to work even when the grid drops down. Can’t quite figure out, will this one do?

A1 SolarStore

Hello. During power outages all inverters are designed to shut down for safety reasons. What you need in your case is an off-grid inverter with batteries, but you won’t be able to connect to the commercial grid with it. This one is a grid-tie inverter, so unfortunately, it won’t do.

mario

08/07/2021

Hi, this looks like a good choice for me, but i heard that these inverters don't deal with shading well which is my problem unfortunately. Any advice?

A1 SolarStore

You can add solar optimizers to decrease the impact of shading on your solar string and inverter production. SolarEdge inverter is actually designed to be paired with them. You can find optimizers in the Solar System Addons section on our website.
