Review for 2 x Ultra X Stream + 8 x 500w panels.

I ordered the bundle in August and everything delivered with a week or two. I'm not a DIY expert but had no problems getting the panels all mounted on a spare flat roof (using a flat roof mounting kit that, based on my research, keeps the install within UK permitted development). Cables run down to the garage and into the stream units.

I've been really impressed with the app and configuration options. We hardly use any peak rate electric now, and instead using off peak power to charge the batteries. I think we will be saving around £500 per year with the 8 panels and 2 Ultra X

Thanks Ecoflow!

Easy set up self explanatory, app is a little fiddly to understand at the start but after a few days it becomes very easy to understand. Highly recommended the smart meter to go with this!

All the power.

Really good battery with enough power to cover the ordinary running of our house with one of us working from home.

The large amount of solar input is great. It is stylish enough to blend in in the living room.

All in all really impressed. i only wish it came with some solar extention cables of 10m+ rather than having to go 3rd party.

Paired with the Smart meter this thing is amazing.

At the time of purchase, a set of 4 x 250W panels were offerred for just £1. No explanation of how to incorporate these extra panels was offerred, and eventually tech support gave a suggestion that did not make any sense.
I purchased an extra micro-inverter and connected the extra panels to that, with the output plugged into one of the battery AC i/o ports.
This is working perfectly with an average output in October with east facing panels of around 7kWh per day. In an ideal setup this would be considerably more, but this is adequate for the low installation cost and should break even within 2-3 years.
As I am retired, there is a constant power use in the home, so the battery has so far not gone past 50% charge, so this system is a good balance for my circumstances.
This relatively low cost method is a good introduction to using solar, compared to the high cost of a roof mounted traditional system.
Highly recommended.

Excellent battery system, easy to install and set up, small footprint and stylish look. The app is user friendly after investing a small amount of time to learn how it works. Combined with solar and low overnight tariff this system is saving me significant money on my monthly electricity bill.

I'm not interested in a large solar array at the moment so this has been great. Works perfectly with two panels and micro-inverter. I did plan on running solar cables straight to the battery but efficiency and charging has been fine via the existing micro-inverter so probably not going to go to the effort of running more cables.

Compact (but very heavy) battery. Looks really sleek. Mine is hidden away but could easily be on display.

Is completely covering my base load and taking a good chunk off high energy usage. Need more time to work out just how cost effective it is though.

App and setup was fairly easy. Had to reset a couple of time at the beginning but running smoothly now.

Tried the battery without a smart meter for a couple of weeks, wouldn't recommend that. It does function without one but is amazing how much energy is lost - smart meter (bought separately) is essential.

I started with the micro inverter but a month in i realized a battery was needed as well as extra panels to make the most of the solar generation.
I went from 2 panels mounted west to 2 more to the east on the summer house roof, the odd time i need to charge the battery due to little sun light but most days there is enough solar to feed the house and charge the battery, my next bill looks like one from the 1990's.

This worked first time out of the box and delivers what it says, which is all you can ask for, really. Set it up in my office log cabin. Obviously takes longer to fill the battery and as my array is only 1280w max (4x Renogy 320w compact -- it was a self-install so I wanted to keep the weight down for easy handling) except on the sunniest days it was struggling to fill it fully thanks to tree shading after 2.30/3pm. But the upside is it lasts twice as long as the Ultra. I've since added an Ecoflow Stream Microinverter in a separate part of the house to cover the base load, which allows the ultra x to charge more quickly.

Great bit of kit. Super easy to install. Instantly saving money straight out of the box! And the app is really great too. Would highly recommend.

Amazing bit of kit. Works flawlessly and has reduced my bills by at least 60% for the last month. And if you have an EV day night tarrif it will still save money even during the winter without solar panels. The only regret I have is not waiting another couple of months for the new 5000 series which would have been alot more suitable for my needs

Happy with the system. All works as I imagined it would

I love the Ecoflow Stream Ultra X. I use it for load shifting for now, but it is making real savings already. I hope to connect it to my plugin solar panels next once they are set up.

Unreal - I set this system up in less than half an hour. Plug and play by definition! Running perfectly and the solar is powering the house for half the day, with the ultra X covering time before and after sunlight. Thrilled with the purchase!

This is an honest review, I am not sponsored or affiliated with Ecoflow ,
all Steam batterys I have bought by myself and like most of you I had to wait for delivery as they are so popular but are worth it.
After seeing a video on YouTube with Mr steve jones DIY that the uk was getting Plug in solar I order a Ecoflow Stream Ultra and an ecoflow smart meter and I ordered 4 solar panels from The Plum Centre that Mr steve jones DIY had recommended and I ordered a drum of 50 meters of 4mm solar cable and mc4 plugs from the plum centre.
I had a local Electrician install the solar panels run the cables, hard wire the power cable into the consumer box (at the moment it has not been passed just to plug in) and the smart meter and he also changed the consumer boxes the one in the workshop and the one in the house as they all needed changing as they were too old.
And put in the BI direction RCD, he also did the g98 form and all other certificates.
I have bought an stream Ultra X and a parallel lead so that they can be daisy chained Together and work as one just under 6 kWh. I am so impressed that I’m thinking of ordering another Ulta X as I find that just under 9.2kWh would work great in running our house and especially over the winter months with the 9p per kW overnight charge that at the moment I don’t need as I’m generating 10 kWh per day with just 4 solar panels.
Im going to be ordering some more panels next year.
Now to Ecoflow customer service which in fair have emailed me back next day and have been very helpful on the phone sorting out some small issue I had.
Now the ecoflow app I know that there will be a new one coming out in the next few months but as Mr steve Jones DIY says sits very well made and it gives you all the stats you need, but it does have a little niggle like it shows that the batterys have been disconnected for a few seconds and them come back on, this only happens on my iphone and it works perfectly on my ipad, so work that out.
There are new ecoflow battery’s coming out in the next few months, but I’m happy with what I have as I don’t have room vertical and maybe they might bring down the prices to reflect this.
There are plenty of videos on YouTube with plenty of advice on installation.
These ecoflow batterys come with 10year warranty, so what you waiting for !!

Just starting on this journey and so far it has been great. Delivery of my complete order took 6 weeks which was a bit of a disappointment.

The equipment is working perfectly and saving me a lot more than I had imagined on my electricity bill.

I’m waiting on the upcoming release of the 5kwh battery and hoping it is not too expensive.

The Ultra X is a great unit - it works fantastically with solar charging and my garden setup. Setup was simple, and I'm already making great savings!

However I would note that if you are aiming to earn through solar excess this system isnt great for that. Get this system if you aim to use all of generation you make.

There is a bug in the system where the battery is not bypassed when full so that solar MUST go through the battery before going to the grid. Example: Battery reaches 100% charge -> solar will stop -> battery will discharge till there is room -> Battery charges back up. It's not ideal but if you aim to use all your generation its not a big deal.

Ordered without any problems. Slight 1 day delay from the courier company. Everything worked exactly as it should after plugging in 4 x 475 watt panels and connecting to a plug. Now saving money every day.

There were a few problems receiving the unit but the company were good in getting it resolved.
They also sent me a different cable for installation to comply with uk regulations.

The unit is really easy to install although final connection to the consumer unit should only be done by an electrician.

Overall I’m very happy with it, it’s like the apple of micro inverters. Nicely packaged & a smart looking device. The app is good & there’s nothing not to like.
