I'm looking for a high-quality discharger that can effectively convert 420V DC into 220V AC. The discharger should efficiently handle a power output of around 3.5kW while ensuring optimal performance and safety standards. It's important that the product is robust and can operate reliably in various conditions. In terms of specifications, please provide details on the efficiency, dimensions, and weight of the unit. Additionally, I'd appreciate info on your production lead times, warranty policies, and any certifications the product holds. If you have any recommendations or variations available, I'd love to explore those options as well. Looking forward to your prompt response!
