@HennieL and the forum, We completely understand the scepticism many members have had frustrating experiences with Pylontech support in the past, and those concerns are valid. On a positive note, Pylontech via Solar Deity and Powerforum is actively working to fix they're after sales support and technical services in South Africa. This is genuinely encouraging and refreshing, especially considering how small our market is compared to the rest of the global renewable energy sector. They are willing to engage directly with the community, which shows real commitment. Powerforum is also engaged directly with Pylontech in China to help facilitate the restoration of their reputation here. Our experience with Solar Deity so far has been very positive they are committed to delivering proper after-sales support and educating both installers and end-users. Many users argue “But the BMS is supposed to protect the battery.” This is fair, however the older BMS units in the US-series had limitations. They could prevent catastrophic events but were not always 100% effective against long-term cell stress from sustained high C-rates, poor thermal management, or frequent high-load cycling. Newer BMS technologies have improved significantly, and Pylontech’s latest protocols have become a standard that many other brands follow. South Africa’s extreme heat and cold conditions also played a big role these are not favourable for older lithium technology. Combined with limited knowledge of lithium systems at the time among consumers, installers, and distributors, some very bad decisions were made around system sizing and configuration. These were not directly the fault of the manufacturer. On top of that, after-sales support was never handled directly by Pylontech it was left to their local distributors. Unfortunately, many of those distributors focused primarily on sales rather than proper after-sales service and technical support. With all of this said, I do not see many other manufacturers that are willing to engage with the consumer directly to repair their reputation. I can think of many brands guilty of very bad after-sales and support. Regarding the trade in “fine print” and process: The process is designed to be transparent and low risk (similar to trading in a used car): - Preliminary remote assessment Completely free. You submit serial numbers, manufacturing dates, and photos via the ticket system. Solar Deity gives an initial estimate. - Physical inspection Also free if you decide to proceed. You send the battery (at your cost for shipping). They test it with professional equipment. - Final offer Binding trade-in value is given. If you accept, the credit is applied to your new Fidus (or other model) purchase. If you decline, you simply arrange collection of your battery no inspection fees, no hidden charges. - No obligation at any stage until you accept the final quotation. If users have specific concerns about “hidden details” e.g. shipping costs, turnaround times, minimum trade in values, or what happens in edge cases like swollen batteries, please state them clearly here or in your ticket so Solar Deity can address them directly. The new products come with far better C-ratings, more robust chemistry, and improved designs. The Fidus (IP65 with 10-year warranty and optional aerosol fire suppression) and their HV range are excellent examples. As a Tier 1 brand, Pylontech has clearly evolved with the market. We believe this partnership is a meaningful step forward. We encourage anyone interested to book a no-obligation assessment via Solar Deity it’s free at the preliminary stage. Appreciate the open and constructive discussion. This helps the whole community move forward. Sincerely Jay
