Fogstar Avis 

I recently contacted Fogstar after discovering that the 5.12kWh stackable battery I had bought only a few months earlier was being discontinued. I had specifically chosen it because the system was expandable and was just about to order another two modules, so understandably I was disappointed to find that my planned upgrade path had disappeared.

What really impressed me was how Fogstar responded. Lydia Kirkby, their Customer Service Team Leader, took the issue seriously rather than simply giving me the standard “product discontinued” response. She explained that I wasn't the only customer asking about these batteries and that Fogstar had listened to the feedback. Management subsequently decided to place another order so existing customers would have a further opportunity to expand their systems.

As a result, I've now been able to preorder the two additional batteries I originally intended to buy.

Product ranges inevitably change, but for me the important test of a company is how it responds when that causes a problem for an existing customer. In this case Fogstar listened and came up with a practical solution, and Lydia was friendly, helpful and kept me informed throughout.

Excellent customer service and a very good reason for me to continue buying from Fogstar.

Recently bought a power station from Fogstar. I love the product very sturdy and looks like it perform as expected. However, I came across an issue with manual, as it was unclear if the device did perform pass-through. I contacted customer support and had a very quick response from Mark.C at from technical support. He quickly confirmed it does do pass-through.
I cannot complain, they are super quick and super knowledgeable. Already feel super happy I went with them.

Excellent service from Mark at Fogstar replied within the hour had the solution to my question and no fuss their batteries are excellent and after service second to none.
Thank you.

Pre Purchase product Question asked at 0725, store closed of course, question answered in full at 0923 by Mark Cheeseman.

Excellent customer service from Mark. Our challenge was resolved with a swift couple of email exchanges. Brilliant!

Adam has been a great help guiding me through various battery options - and Fogstar itself has made sure it is right up there in terms of product quality and reputation.

Bought battery 20 months ago and very happy with the service it has given me. Had an issue recently re updating the app and had great support until matter was fixed.
Happy to fully endorse both the product and the technical support provided.

Fantastic support and knowledge from Mark in Technical Support helping an electrical newbie and van owner understand how to monitor battery usage via my Vitron set up.

Their service and quality is second to none. in all the time I have been dealing with them I have only had one faulty product which they have tested, reviewed and replaced within a week. I cannot fault them. Even tho the returns system is automated it appears that there is human oversight to avoid the circular conversations you can get into with automation.

Great service as always, always someone willing to answer my questions.

Had a problem with my fogstar battery not charging with fogstar charger , the customer service team answered and resolved the issue very quickly. Very quick and helpful after care.

I purchased through Graham Mellor a Fogstar Drift 300Ah lithium battery in 2023 which Graham personally installed together with associated equipment.it worked perfectly well until August 2026, albeit I regret not having bought a larger battery for my beach chalet, which used at intervals in the winter when I had to be more power-use conscious than in the summer.

On advising Fogstar that one of the 4 cells in the battery appeared to be defective and thereby resulting in the whole solar power system breaking down, they were immediately helpful in terms of determining from screen shots that my analysis was justified, it was covered by their 10-year warranty and hence they arranged for the battery to be collected for inspection and repair as necessary.

Fogstar advised me throughout of progress and subsequently returned my battery which was checked on site by a solar engineer (Ollie Longley) who has in contact with me since.

Initially the cells appeared not to be working in conjunction with each other but I followed Ollie’s advice to “let the system settle down”. After nearly a fortnight the cells appear to have done so, although the “protect history” indicates that there have been over 20 “Cell overvoltages” since the repair.

I emailed Mark Cheeseman, Technical Department at Fogstar, on 28 August to update him and query the apparent problem I have and to date am still awaiting a reply. All I have received is advice that my ticket (works order) has now been closed.

Prompt sensible reply to pre sales enquiry

Chavarna inc customer services was very helpful - all sorted via email.

I had an issue with a lost PIN code for my battery. Mark Cheesman at Fogstar support was so helpful in diagnosing the issue and sorting the problem out. Fantastic product and great support, doesn't get any better, thank you Mark

After having a battery installed in my camper, I couldn't download the manual. Adam answered my email very quickly with the necessary links. All very efficient and helpful. As for the battery, seven nights off grid and still plenty of energy in it. Thanks Fogstar.

Great customer service. Needed support twice, even before the battery I bought was installed and was helped quickly and effectively in both occasions.
One of them was related to the cables to connect the battery to the inverter, which required replacement. Shipping was done surprisingly quickly. Thanks Adam!

Very responsive and understanding customer service (Keira was wonderful!) and quick turnaround by the engineers. Thank you Fogstar!

Fantastic service from Fogstar again. One of my battery brackets went missing in the post, Fogstar tracked it down and it arrived that afternoon. Big shout to Chavarna Clarke from Fogstar who dealt with my issue and made it work out.

Great service, Lydia at sales helped me make the right choice and even helped me with a discount code! Highly recommended!
