Avoid Like The Plague Premium Costs Bottom of the Barrel Service
If you are looking to purchase solar or off-grid power equipment from a company that will actually stand by its product and warranty commitments, look anywhere else. Dealing with Renogy (RNG International, Inc.) has been an absolute nightmare from start to finish. When my 12V 200Ah Smart LiFePO4 Battery (Model: RBT200LFP12-BT) suffered a total, unrecoverable internal BMS and Bluetooth failure through zero fault of my own, I expected a straightforward warranty replacement. Instead, I was dragged through weeks of stonewalling, deflection, and endless stall-and-delay tactics by a support team that clearly has no intention of honoring their legal obligations. The worst part? They actually attempted a fraudulent bait-and-switch: trying to sneakily substitute a lower-tier 100Ah unit to outright strip 50% of the capacity I paid for. When confronted with verified technical isolation logs proving the unit was dead, management completely shut down communication. Their customer service is a ghost town of empty promises, automated deflections, and bad-faith maneuvers designed to exhaust consumers into giving up. They do not care about quality, safety, or basic business ethics. Save your hard-earned money, avoid this company like the plague, and take your business to brands that actually respect their customers and back up their gear. Formal small claims legal action and statutory violation filings are already underway—do not let them do this to you. Updated Review 8/17/2026: If you are looking to purchase solar or off-grid power equipment from a company that will actually stand by its product and warranty commitments, my experience is a tale of two extremes. Dealing with Renogy (RNG International, Inc.) initially turned into an absolute nightmare from start to finish. When my 12V 200Ah Smart LiFePO4 Battery (Model: RBT200LFP12-BT) suffered a total, unrecoverable internal BMS and Bluetooth failure through zero fault of my own, I expected a straightforward warranty replacement. Instead, I was dragged through weeks of stonewalling, deflection, and endless stall-and-delay tactics by a support team that clearly lacked transparency. At one point, I faced frustrating hurdles, including a brief scare over tracking movement and a support loop that felt designed to exhaust consumers into giving up. However, I want to update this review to reflect how the situation ultimately shifted. Once I was finally directed to the appropriate representatives and supervisors took charge, the entire dynamic changed. Management stepped up, held the company to a standard that was acceptable and reasonable, and made good on their warranty by providing a brand-new, top-of-the-line replacement battery. Furthermore, they assured me that my critical feedback and technical logs were being taken seriously as they review their internal logistics and support policies. When Renogy's products work, they work great—and in the end, once leadership intervened, their customer service did too. I am pleased with the final outcome, have dismissed my legal filings, and sincerely hope they continue on this path. I just want to see their frontline customer service consistently match the innovation and usefulness of their hardware.
