Tigo Energy Reviews 

In Oct 2023 We had 19 panels, each with a Tigo Optimiser fitted, from the start 4 or 5 were not communicating with the access points (2 access points were fitted as its an East West array). The installer in Essex, UK was unless in solving the issue and it was left to me to email Tigo. They did send out 6 units because by March 2025, 6 had completely died and the installer that had fitted them charge us £390 to replace them. I can't recommend Generate and Store on this basis. To date 9 out of 19 optimisers have failed. All replaced by Tigo but the last 3 replaced/fitted by myself with a friend and then added to the app by Tigo.

Had Tigo optimisers on the roof installed by a local installer. 4 years in and some of the optimisers stopped working. The installer contacted Tigo and Tigo agreed to replace the optimisers, but the installer wanted to charge Tigo way above the going rate for installation and their negotiations halted. The installer then gave my details to Tigo for me to continue the conversation - except they didn't copy my phone number correctly and no one from Tigo ever got in touch with me. When we got in touch with Tigo they were prepared to find an installer who would charge a reasonable rate, but for some reason this didn't go ahead and the last conversation we had with Tigo was them telling us that it's not their responsibility to install the new optimisers and it's our job to find an installer. I do believe CAV will tell you it's Tigo's job to arrange for installation of their failed product. Instead we are now met with silence. This has taken months and we are obviously not making as much power as we should be and therefore doubly out of pocket. Tigo need to learn that when YOU manufacture a product that fails then YOU are responsible for the replacement of the failed components. Not the customer.

A Tigo optimizer does Not communicate anymore. Tigo Support tries from the First second to Push the fault to the Client instead of helping to solve the problem. To do do, they make clearly false claims.

When I decided to purchase a solar system and battery, I researched Tigo products and they seemed to stand up pretty well in the articles I read. What I didn’t realise is that the support centre is in Italy and they don’t work over national holidays. The only way to log a ticket is via a WhatsApp chat and they just ignore me, the USA seems to have a web page to at least log a ticket. I don’t have any visibility of the components via the app as most features are only visible to Tigo and the installer. I bought the expensive premium add on and it gives me nothing extra except more access to download data. The Tigos were down for most of December and part of January and the app said it was healthy each of those days when it was totally offline. The app is not secured via 2FA this is dangerous. Next time i buy a product, I would look more closely at the customer product reviews rather than press articles.

I am deeply disappointed with both the product and the customer service provided by Tigo. The devices themselves fall short of expectations, and the backend system has serious flaws, particularly in handling user data. I initially opted for Tigo optimizers to track individual panel production and maintain access to historical performance data. Unfortunately, after a recent database update, all my historical data was lost. This completely undermines the purpose of investing in such a solution.

After reaching out to customer service, I was told that my data would be recovered. However, after months of waiting, communication ceased over a month ago, leaving the issue unresolved.

Given that I invested close to £1,000 into this system, the lack of responsiveness and reliability is incredibly frustrating. I would caution others to carefully consider these issues before investing in Tigo's products. At this stage, I cannot recommend them based on my experience.
