Broadbridge Heath Village Centre…

Lewis has been extremely helpful with sorting the battery charging issues we had. Very professional and friendly, nothing is too much trouble and with the support of Jed, the team effort has been first class and we have been kept informed at all stages. Thank you.

Fox Cloud 2 App

I have just had a fox ess evo 10kw battery integral with an 8Kw inverter installed on 27th January. So far I am unable to schedule charging periods with the Fox cloud 2.0 app. This is my whole reason for buying this, together with PV panels. To take advantage of cheap electricity. The installer has been in touch with Fox but are still waiting for a reply. At the moment I have paid out thousands with little to show for it.

Samantha and Steven from Fox Ess took ownership of this issue and resolved it. I also now have a phone number to call if I have any further problem.
A big thankyou to Sam and Steve.

Hi Peter. We will reach out to you via trustpilot for more information. Charge scheduling is a standard feature, so if this is not working there will be a settings issue that needs to be addressed. I can't find any ticket reference, so I will message you for more information so that we can look into this directly as a priority. If you can reply to the information request with your serial number and contact email we will look into this.

I’m an electrical renewables installer…

I’m an electrical renewables installer and business owner, and I deal with Lewis at Fox on a regular basis. Lewis consistently helps us troubleshoot installation issues, and to date, there hasn’t been a single job where he hasn’t been able to assist.

He regularly goes out of his way to help, keeps you updated throughout the process, and—most importantly—is always polite, genuine, and easy to deal with.

I wouldn’t hesitate to recommend Fox and Lewis to any renewable installer or homeowner.

Good customer service

Fox has a good customer service compared to their competitors.

I recently reached out to the support team, got in touch with Samantha Buckner, who resolved the issue promptly. Special thanks to her!

Issue with new fox battery system and…

Issue with new fox battery system and fault. Lewis rang me back immediately, if not sooner. It was complicated issue, but 5 phone calls from (allowing time for changes to occur) in 2.5 hours and Lewis has become my man crush of the day. Really professional and resolved what seemed like a hopeless situation. I am LEWIS's biggest fan. Mwaaah

15 Months of Fox ESS Battery, Inverter and Customer Service.

I have now had my Fox ESS Solar up and running for 15 months. Being an older Gentleman I have struggled to understand certain parts of the system. But, Fox ESS are always on the end of an email to assist whatever your issue is. Lewis at Fox ESS is amazing and is always willing to assist. I have had several comments from Trades people (I live in a new build so going through snagging process - lots of trades people in/out) on how smart the system looks. One electrician even commented on how reliable Fox ESS products are and their robustness.

Fox cloud connectivity problem

We had a period of time without connection, I emailed the helpdesk and withing minutes I had support. Had to get in touch a second time as the connection was playing up and Lewis replied again with a couple of minutes. I am now back online with the fox cloud app. The explanations were really clear and I was also provided with a video walk through. Can't recommend highly enough. Thank you. Sara

We would just like to say how satisfied…

We would just like to say how satisfied we were with the service by both Redell and Craig, who help with the installation of the app for our solar panel system. Having being frustrated by the company who installed the system into house initially, we contacted Fox ESS UK directly and found them to be both polite, patient and knowledgeable in their assistance to both of us.
Thank you for all your help

Installer Review

As an installer we've had to lean on the tech team at Fox ESS Uk, quite a bit (weekly). For the most part we've been dealing with Samantha, who has been phenomenally helpful - If only every manufacturer could have a Samantha in their team. That said, the rest of the team have always been quick to respond and helpful.

Quick, efficient response/resolution.

System installed May 24. Quite a lot of Firmware updates causing Issues and delayed/slow responses to resolve at times ( suspect Service guys were very busy) but all settled a few months back. Small issue reported with Blocked Setting MinSOC on grid reported on Sunday evening resolved remotely within 24 hours, Lewis provided good and clear info. Hopefully, a sign of how will be in the future. 😉

Jacob Chinger is a legend!

Jacob Chinger genuinely made our experience with Fox 10 times better after he was made a POC for this particularly difficult and strange system fault. we had previously had some issues with Fox's after care for our customers but Jacob has been an absolute star. He took on a real head scratcher for us with the AIO system we installed and seamlessly helped us put our customer at ease with the useful information he quickly provided to us. Jacob really did go above and beyond with our after care with his research on the system outside of his work hours as well - the man needs a raise - what a legend!

Battery only Fox ESS system Firmware update…

I've had my battery only Fox ESS system for nearly a year now and I've been very happy with the way it unobtrusively gets on with the job, The firmware was remotely upgraded when it was first installed. Having seen that the app had been upgraded I decided to see if there was a similar upgrade to the firmware in my system. I contacted Lewis and he confirmed there was and he remotely installed the latest firmware for me.. All in all a very nice and efficient backup..
