Product DescriptionProduct DescriptionMOREDAY PV combiner boxes are designed to consolidate the DC input from 4 to 36 PV strings into a single output. Each input channel is equipped with a fuse, while the output side includes both surge protection (SPD) and a circuit breaker. This greatly simplifies the DC wiring between the solar modules, distribution cabinet, and inverter.The combiner box provides multiple layers of protection, including lightning protection, short-circuit protection, and reliable grounding. It is available in two types: intelligent and non-intelligent versions.The intelligent PV combiner box is equipped with a monitoring unit that enables real-time monitoring of:Input current for each stringInternal temperatureSurge protection statusCircuit breaker statusOutput voltage summaryThis solution enhances system safety, reduces installation complexity, and improves overall maintenance efficiency for both on-grid and off-grid solar systems.The design and configuration strictly follow the "Technical Specification for Photovoltaic Junction Equipment" (CGC/GF 037:2014) standard.We provide users with safe, efficient, aesthetically designed, and practical photovoltaic system products.The product features an outdoor wall-mounted design, making it suitable for harsh environmental conditions.While the core components are standardized, other configurations can be customized according to user requirements.Product NameDC combiner boxModel CodeMDJB-PV4/1Rated Voltage1000VInput4stringsoutput1stringTemperature range-25oC~+55oCCertificateTUV / CE / CB / CCC/TUV Australia approvalEnclosureIP Protection Class(IEC60529)IP65MaterialsPolycarbonate / ABSSpecUV resistance and Flame retardantDC switchRated Voltage1200VRated Current32ADC SPDMax Operating Voltage1000VMax Discharge Current40KANominal discharge current20KADC FuseRated Voltage1000VFuse link15A 10*38MMMMFinger safe touchYESLED indicatorYESRelated ProductsAries, Gemini, Virgo DC charging pile series standard power 30kW/40kW/60kW/80kW/120kW/160kW (up to 1360kW can be customized)Cancer standard power 60kW/120kW/160kW (customizable)Portable electric vehicle charger standard power 3.5kW/7kW (customizable)Company ProfileMindian Electric Co., Ltd. is a high-tech enterprise integrating R&D, manufacturing, and sales, specializing in smart power distribution and renewable energy solutions.
