SolarEdge SE-P850 Power Optimizer 850W

Super reliable inverter, produces great output and easy to monitor

Runs fine simple to use quiet and efficient happy overall.

Had it running 6 months now works smooth no issues at all so far.

Easy install lightweight and I like the app very clean interface

thx for your help

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.

well i mean they work lol but the whole idea of them is stupid hope solaredge will make better inverters but the service at a1 was very good

the package arrived late but the inverter is great, very easy to set up, monitoring is intuitive and the production is good. liking what i'm seeing so far

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!

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 package arrived on time! Great service, thank you guys

It was a great experience dealing with your company. I will recommend your company to anyone in the market for solar panels. You provided excellent service, value and customer satisfaction.

We just wanted to say thank you for a great experience having our new Solar PV system. From start to finish you guys have been courteous and professional .

thanks for pickup option!

Very good inverter, a bit loud but it's fine, we put it in the garage. two years in and no real problems to speak of.

We purchased the inverter for our shop in Oklahoma. The installation was very simple, much easier than I anticipated. It is silent and doesn't take up much space which is important.

Thanks to your excellent website and all the help it offers. I have no hesitation in recommending you to anyone thinking of “going solar”.

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!

I like how the solaredge app is made: it’s very simple and intuitive. a1solarstore was also very helpful with recommendations

thanx for the fast responses and recommendations! the inverter is great!

don’t have an electric car yet, but considering how little it takes to be EV-ready, it is certainly worth the extra money. The staff is very friendly and helpful, I appreciate your attitude toward clients

Great service! Thanks for delivering it on time, it was actually a birthday present to my brother)

These power optimizers are awesome. I'm using 4 of them currently. Their efficiency is phenomenal. I can recommend both the product and this store.

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.

I’m surprised no one made it before SolarEdge, this idea is brilliant. I also got a reasonable price from A1. This device DOES save you money and time

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

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.

The inverter works fine. I appreciate how easy the installation was. It is very silent too.

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.

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!

The inverter may look huge in the picture, but it’s not all that big and indeed is very light. The performance is good and as of now i have no doubts that it will last for a long time

i was choosing between microinverters vs a string inverter plus optimizers. Guys from a1 advised me to go for the second option to save some money. thanks a bunch!

Thanks for the recommendation and the fast delivery! The inverter was indeed very easy to install. The guys from utility said i made a good choice

I’m loving my SolarEdge inverter and optimizers. The system has been installed for over six weeks without the least sign of trouble. We picked premium LG modules and wanted to track the performance of every one of them. Thank you for great prices and fast delivery!

I was in a bit of a hurry and needed the equipment asap. 2 days after placing my order with A1 I was already driving home after picking up my purchases at the warehouse. Excellent service, will come for more!

the package arrived on time! Great service, thank you guys

Happy with the purchase, thanks

I ordered six units and I love them all. They are small, very very efficient and extremely reliable. The optimizer’s size allows it to fit into tight places. The installation was easy as well.

picked this one up from the warehouse. Very satisfied with the service. The inverter is all right, but honestly i wouldn’t recommend installing it outdoors – here in california it heats under the sun fast and production falls down. I moved it into the garage and it’s all good now.

If you have an EV, this inverter is just the right thing to save money

My installer recommended getting a Solaredge inverter, so here i am. thanks for fast delivery, i appreciate the fact that you shipped it for free. I placed it in the garage and so far works great.

i got it. tnx

Just extended the warranty to 20 years. Love the product, the store and the brand!

I found the inverter to be a bit bulky, had a hard time figuring out the right place for it. Overall I would say the model is good and worth its money.

The delivery was a bit slow because of holidays, but the guys didn’t charge me for it. They said that they ship inverters for free right now, so that’s great. The inverter is so-so, nothing too special in my opinion, but it looks good and it does its job

The inverter itself is great, but I kinda wish it had bigger output. well, should have chosen a bigger model i guess. it was easy to install and connect to my iphone. overall, i’m satisfied.

The package arrived much sooner than I expected! Thanks

Picked the units two days later at the nearest warehouse. Great feature! They are still waiting to be installed, but I have no reasons to doubt their quality, I’ve worked with them before

1. Very heavy solid device 2. The manual is very well written and clear 3. Just works

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.

I was led here by my installer’s advice. The store answered my calls promptly, offered good pickup locations and processed the order promptly. Keep up the good job!

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 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.

I was planning to have a grid-tie installation, but eventually decided on picking batteries along the way, so this inverter became something like a middle-of-the-road option for my situation. It was the right choice eventually. Thanks for the fast delivery!

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.

I sized the system with your calculator and picked this inverter just to be free to go off-grid if I ever get such a temptation. thanks for the fast delivery, the inverter looks very good and i also noticed how light it is. take care, R

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.

SE equipment is simply the best. Turn it as you might, it gives the best reliability, functionality and efficiency for every spent dollar.

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.

This model was recommended to me by a1solarstore staff and my installer as well. I picked it together with my REC panels and so far there hasn’t been any issues. Thank you very much, I enjoyed working with you!

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.

I stick with SolarEdge optimizers. They install fast and do the job well

Thank you so much! The package arrived, everything seems to be in place, nothing was broken. glad that we can start building the system

Some parts of my array would be inevitably shaded during the day. To cope with this issue, I’ve opted for a SolarEdge inverter plus power optimizers. It was a good decision

Great prices, a good pickup location and outstanding service. I think I have added to the list of my favorite online shops. The devices do the job as described.

A very versatile and powerful product. Obviously, this one is for smaller installations like mine. I was quite impressed with the level of efficiency that this inverter shows. It is so compact and lightweight too!

A very strong and versatile inverter. We’ve installed three of them for our hospital in Boulder county. The energy backup was the right decision because we cannot tolerate any blackouts.

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 purchased this model a couple months ago. It is very silent and basically i don’t even notice it. I think it updated itself one time since the installation. Does its job very well. I was monitoring the system in the beginning, but now i grew a little bored of doing it. thnx

I picked this inverter last Monday from the Sacramento warehouse. It works very well. Before the purchase I've studied all the articles about inverters on your website, they helped a lot, thanks!

I purchased three of them for my shop in Alabama. Never have I ever seen 99% efficiency before. Quite impressed, I barely lose any energy in the transfer. For this money, it’s a great deal.

Thanks a lot for the help and the service!

Standard residential inverters are about 95-98% efficient, while the SolarEdge inverter + power optimizer have an efficiency of about 99.5%. This was enough for me to make a decision

It is actually smaller than I expected it to be. I put it in my garage, it has already connected to my iphone. right now we are discussing the connection to the grid with electric company.

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.

I use these together with SolarEdge inverters to get the best result. It’s my favorite configuration. It was my first purchase with the store and I plan to continue the relationship

Very efficient, very compact, very silent. I like the fact it tells me where my energy goes all the time. I started trying to optimize the usage of electricity in the house because of it.

I had some shading issues and read that a power optimizer could help. A1 store offered the best price and shipped the order that same day

I really appreciate you taking the time to respond and for answering my questions so simply.

Advanced Solar is probably the most professional, considerate and capable company that I have ever known.

All the staff were friendly, professional & truly enjoy their job. That is great to see these days.
