Further to my previous review:
Further to my previous review: After more than three weeks of correspondence and testing, Renogy agreed to replace the MPPT and issued a returns label. Within 48 hours and on a Fri, I received notice the case would be closed if the MTTP was not returned within 48hrs. I therefore had to remove the unit and return it on Saturday morning, and provide tracking details as requested. On Tuesday I was informed a replacement order had been raised. As of Friday afternoon, it has still not been dispatched. The only update received, following my enquiry yesterday, was that it had “not yet shipped.” Renogy’s response to my prior Trustpilot review was dismissive in part "when you believe", I completed all requested diagnostics and submitted the results. I was also directed to use a “messages” tab in their service centre, which does not exist; all communication has taken place correctly via the case section messages in the service centre from the outset. My decision to highlight the problem with Renogy is not based on the product failure, but on the poor customer experience. 'We appreciate your feedback and look forward to working toward a satisfactory resolution.' are just empty words, I actually feel sorry for the staff who are clearly poorly trained both technically and in comms and are using inadequate systems and processes. Terrible customer service for repairs Having purchased several items for a campervan conversion I was failing to get the MTTP to charge the leisure battery from the alternator. Everything else seems ok, have power where and when Im supposed to but it doesn’t work, I have been in a long winded (2+ weeks) online only, discussion with Renogy regards testing and proving and videoing everything, each time I do so, I get fobbed off with something else to try, it has now come to the point where they are asking me to recheck the things I already sent videos for, and thy are incorrectly responding to what I have told them, their customer services are shocking, I have spent countless hours following their advice, when the issue is a faulty product. however they refuse to answer when I ask how to go about replacing it. Product is 6 months old but was not fitted immediately so effectively new, I am a qualified electrician and Chartered Mechanical Engineer so not new to these things. After this experience I will not be buying Renogy products again, the products I bought that work are good value and seem to be reasonable quality, but when they don’t work you’re in trouble if you want to repair or replace. Guarantee not worth the paper it’s written on
