Since having a 20Kw battery installed 2 months ago, it has been working as expected with no need for any support.

The equipment is excellent. My only caveat is that Powervault experienced a number of teething problems which rendered the unit useless for some time. However Powervault persisted in addressing the situation and to their credit made an ex gratia payment to cover lack of revenue over the period,

The process from quote to installation was pretty straight forward, apart from the DNO application which is outside Powervaults control.
Daryl who did the installation (P5 + gateway) did a great job fitting our system and fixing a few issues during commissioning. The system has worked without an issue since then and reduced our electricity bill over the last two months to zero.

Shane has always been very responsive before and after sale, but the after sales support could be improved - I've been waiting for a respone on setting up Smartstor with a particular tarrif for longer than I had hoped. It might be useful if Powervault could setup a customer forum, similar to the Octopus Smart Energy one, where customers could share tips and Powervault employees could help support them.

To join the many recent comments and customer experiences my rating has now dropped from 5 to 3. Although my P5 is still working my longer term confidence in it and any support from Powervault+ has plummeted. At the moment there's one guy in support who seems to be holding the fort for customers with a P5 battery, owners of P3 systems have been given a rough ride and I worry that the same will happen to P5 owners soon. I still don't have an insurance backed warranty so am at risk of losing the significant investment I made last year

Good quality battery to work with our solar panels. Large capacity and the app works well alongside it.

Great interface so you can see how much energy is coming in and match your use of car charging/washing machine use to solar energy coming in. Battery is exterior and modular and looks nice and sleek. You can also force charge the battery overnight when the energy costs less if there isn't much sun, which we find really helpful. Powervault team were responsive and dealt with an initial software glitch pretty speedily. Cost of battery and installation seemed pretty reasonable.

the tech is good - it works .The company are responsive and reply quickly to my enquiries .I feel engaged with the company and feel comfortable with their ethos .My battery has also had a profound effect on my electricity bill in a very good way for me .

Had a lot of problems with the Internet connection to start. The engineers and installers both worked together and got the problem resolved. Top marks to both for the manner in which they dealt with and resolved the problem. The powerwall itself is fantastic. I've told it which import and export tariff I'm on and I can see how it is working via the portal. Given the cost of electricity now I think it will pay for itself in no time.

I had 16kw of P3s fitted Summer of 2022 (+ solar panels) - currently looking at payback within 5 years. Has proven to be an excellent product. There have only been a few minor technical glitches which have always been sorted promptly by the support team of Shane, Mo & Co. Great to have the phone answered promptly by a knowledgeable real person. Excellent British Company.

Equipment appears robust and well manufactured, casings are powder coated steel - time will tell the resilience of the equipment and the batteries.

Installation was OK, however, still waiting on some snagging to be completed.

Portal is pretty good and usable, however, the Smartstor feature needs a LOT of work, at the moment I am setting a schedule manually every day which is onerous and time consuming and something I wasn’t expecting to have to do.

Post sales support has been good on the whole, especially from a chap named Shane - he has been excellent.

I have tried to engage with the company regarding the Smartstor function to help them develop it better, even offering to be a beta tester, (after all I’ve invested several thousand pound into this product), however, the response has been limited which is very disappointing, this is the key reason why I’ve only scored 3 stars. If the Smartstor software did what it was marketed to do then it would be 4.5-5 stars. (One example being in Smartstor mode, it chooses a status of “Only Charge” during non daylight hours, the manual states that the battery will only charge using solar during this status - night-time!!!)

Overall I expected better so am left disappointed and wondering if I should have gone Chinese rather than British.

I contacted Mo in Powervault's Tech Service Dept as my unit had stopped working about 10 days ago. His advice was spot on and within minutes I had my system back up and running again. This is the first time this has happened in eight years and I can only recommend Powervault for their very good battery and efficient after-sales service. I didnt even have to wait ages in a queue for my query to be addressed!

The P5 Powervault 6KW system now operational for 2 months and has exceeded expectations with output above predicted. The Powervault app is very intuitive but does need a refresh button if looking at for any length of time. Goes without saying that a British made system is always preferable.

Battery great. Weather great. Washed panels, even better.
Smartstore potentially great. Still bit confused with respect to export vs storage from solar when my export tariff pays 2x more than my import night tariff with Octopus Go. So switched off Smartstore for now?

Had a 15kWh P5 system With Gateway fitted by the Orca Renewables team who made the install go smoothly. It been running for 2 Months now and I am very impressed. The system was fitted inside my dethatched garage and the 16 panels on the metal roof all with optimizers. Gateway was mounted the the house close to the consumer board. The hole system is a very neat package.
The Powervault portal app is easy to understand and to use. I set it up to operate with the Octopus Flux and let the A.I system do its own thing.
We now pay almost nothing.
Hopefully looking at between 5 to 7 years for full return of investment. Depending on the unpredictable weather.
So if you are looking for solar you really can't go far wrong with Powervault. And please if you can, Use Orca. I was really impressed with their knowledge and hassle free install.

Too noisy. Would not have bought it if I had known it would be so loud.

Fantistic bit of kit that does exactly when it is meant to. The Powervault team are excellent too and can't do enought to provide support.

Great system, installed a Powervault system with PV panels in London. The battery looks good and works wonderfully. It connects to the grid and panels, and has an easy to use app that gives an informative dashboard and lets you change settings to suit your energy tariff. We connected to the Octopus, Agile tariff, which means with the battery SmartSTOR builds a bespoke charge and discharge schedule, taking advantage of the lowest prices (including negative ones) to charge and to disscharge at the highest prices, while also taking into account the solar generation and household power needs. Finally, given power outages recently affected Spain and Portugal, having the Emergency Power Supply (EPS) at the click of a button is a huge reassurance.

I have been following Powervault from the beginning and had a P3 unit with 12kwH chassis installed some years ago. Initially, 8kwH batteries were installed with the hope of getting the extra 4kwH added later. About a year ago I was informed that batteries for my unit were being withdrawn. Very recently, some of my batteries stopped working properly and needed to be replaced. I discovered that they just needed to be balanced; this was successful. The engineer has removed and replaced the units which are now okay but Powervault won't let me have the, now functioning, units installed into my 12kwH chassis. This would have been a reasonably straightforward job and would have prevented perfectly good batteries going to waste. Powervault would rather sell new units than support existing customers.

I like the way you keep an eye on my recent installation

I have recently had a Powervault P5 battery storage installed. I had a few questions after the install and found the customer service team to be very helpful and approachable. I would fully recommend Powervault to any one looking for a British storage system

I have had a Powervault battery for 8 years. Recently had a heat pump fitted and so a larger one was really required. A new P5 was put in and the old one removed neatly within a day. A seamless transition to the new one, now allowing us to use only off-peak electricity, all year round, and with luck only self generated solar in the Summer months.
