FAQ
Q: What is the IP waterproof rating of the panel and the junction box?
A: The solar panel body and the backing fabric are rated IP67, making them highly resistant to heavy rain and dust storms. The integrated junction box is fully sealed and potted with silicone to prevent moisture ingress, ensuring safe operation during sudden downpours.
Q: What type of output connectors come standard, and can they be customized?
A: Our standard configuration comes with a heavy-duty 3 meter cable terminating in MC4 connectors, which offers the lowest resistance and universal compatibility.
Q: At 16.45 kg, the panel is relatively heavy. How is the ergonomics handled for one-person deployment?
A: To balance this, the panel is engineered with a rigid, reinforced double-stitched rubber carrying handle and a balanced weight distribution, allowing a single operator to lift, unfold, and position it easily via its built-in adjustable kickstands.
Q: Which international quality and safety certifications does this product hold?
A: The SOLAREPOCH 400 is fully certified under CE, RoHS, and FCC standards. The solar cells themselves comply with IEC 61215 and IEC 61730 quality testing. We provide full compliance documentation to support smooth customs clearance in the US, EU, and Australia.
Q: Can you provide customized user manuals and retail-ready packaging for Shopify sellers?
A: Yes. We have a dedicated design team that can provide print-ready, high-resolution neutral packaging or custom-branded boxes that comply with Amazon drop-test standards.
