Very Bad Turbines. Copies. Stay away Jay

@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

I fully agree. Let me ask the Pylonytech gents to attended to this thread. Standby Jay

# Official Statement regarding Pylontech Battery Warranty and Technical Diagnostics First and foremost, we sincerely acknowledge the concerns and feedback raised by our valued customers. We understand that receiving an out-of-warranty assessment can be disappointing, particularly when a battery has experienced a significant failure. As the Official Service Center for Pylon SA, we are committed to providing transparent technical evaluations, consistent warranty decisions, and professional after-sales support. We therefore wish to clarify the following principles regarding our warranty policy and technical diagnostic process. ## 1. Warranty Period and Eligibility The standard product warranty period is five (5) years from the original date of purchase and may be extended to seven (7) years upon successful product registration in accordance with the official registration requirements. During the applicable warranty period, Pylon SA will repair or replace products free of charge, provided that the product meets all conditions specified in the official Warranty Terms and Conditions. Warranty eligibility is determined through technical evaluation and cannot be established solely based on the presence of a product failure. ## 2. Technical Evaluation Process Every warranty claim is assessed individually by qualified technical personnel. The evaluation is based on multiple sources of objective evidence, including the operational records stored within the Battery Management System (BMS), physical inspection of the battery, and verification of the installation and operating conditions. This standardized evaluation process ensures that every warranty decision is made consistently, fairly, and based on verifiable technical data. ## 3. The Role and Limitations of the Battery Management System (BMS) Every Pylontech battery module incorporates an integrated Battery Management System (BMS), which continuously records operational telemetry and historical system events. These records provide the primary objective evidence used during technical investigations. The BMS is designed to protect the battery by monitoring critical operating parameters, including voltage, current, temperature, and communication with compatible inverter systems. However, like any electronic protection device, the BMS is designed to operate within specified operating limits. Conditions that continuously exceed these limits, or prolonged operation outside the recommended specifications, may result in irreversible battery damage that cannot always be prevented by the BMS alone. ## 4. Clarification on Out-of-Warranty Determinations For every battery determined to be outside warranty coverage, a detailed technical inspection report has been prepared based on the available diagnostic data. We would also like to clarify that battery cell swelling should not automatically be interpreted as evidence of a BMS malfunction. Battery performance and safety depend on the interaction of the battery, inverter, installation quality, operating parameters, and environmental conditions. Even where a BMS is functioning correctly, prolonged exposure to conditions outside the specified operating limits may lead to irreversible degradation that falls outside the scope of the product warranty. ## 5. Commitment to Customer Support Pylon SA remains committed to supporting our customers throughout the entire product lifecycle. In addition to providing professional technical assistance and warranty services, we continue to work closely with installers and distributors to promote correct system configuration, firmware compatibility, proper operating parameters, and best installation practices in order to maximize product performance and service life. Should any customer believe that additional technical information relevant to a previous warranty assessment is available, we welcome its submission through our official service channels for further review. We appreciate the continued trust of our customers and remain committed to delivering reliable products, transparent technical assessments, and professional after-sales support. How it works: Visit www.powerforum.co.za and click on the Pylontech banner on the main page. The Link will take you to the official Pylontech support page scroll down to book a ticket. To Register your old batteries for testing book a ticket stating you want to trade your old batteries in as advertised on Powerforum and state manufacturing date of your batteries also state the serial number of each battery. Click Submit. Solar Deity will contact you and take you through the rest of the process step by step. Solar Deity will professionally test your batteries and provide a trade in value. Use that credit when you purchase the new 16kWh Fidus (and other new Pylontech models) through our store.

Well done Sir, Well done.

BYD beats BMW and Volvo in record month for electric car...BYD accounted for 81% of the EVs sold in South Africa in March 2026, which was the first month it reported sales figures to Naamsa.
