ACDB / DCDB / Solar Junction Box Solutions – Safe & Efficient Solar Power Distribution 🔌 1. DCDB – DC Distribution Box Product Overview The DC Distribution Box (DCDB) is designed to receive DC power from solar PV strings and safely distribute it to the inverter. It provides protection against overvoltage, reverse polarity, and short circuits using DC-rated MCBs, MCCBs, SPD (Surge Protection Devices), and fuses. Key Features Combines multiple DC inputs into one output Pre-wired and factory-tested for easy installation IP65/IP66-rated for outdoor use Integrated surge protection and fuse disconnects Available with monitoring (optional) Typical Specifications Parameter Description Voltage Rating Up to 1500V DC Input Strings 1 to 24 (customizable) Output Ways 1 or more Protection Devices DC MCBs, MCCBs, Fuses, SPD Enclosure Type Polycarbonate / Powder-Coated MS / FRP Protection Class IP65 / IP66 Standards IEC 61439, IEC 60364, IS/IEC 60947 Applications Rooftop solar PV systems Ground-mounted solar farms Off-grid and hybrid solar systems ⚡ 2. ACDB – AC Distribution Box Product Overview The AC Distribution Box (ACDB) distributes the AC power from the inverter to the utility grid or load. It includes protective devices like MCBs, MCCBs, ELCBs, and SPDs to ensure safety during grid faults, overcurrent, or overvoltage events. Key Features Manages output from the solar inverter Ensures system safety and fault isolation Built with branded protective components Optional metering and monitoring provisions Designed for single-phase or three-phase output Typical Specifications Parameter Description Voltage Rating 230V / 415V AC Inverter Compatibility Single or multiple inverters Output Connection Load / Grid Protection Devices AC MCB, MCCB, ELCB, SPD Enclosure Type MS, FRP, or Polycarbonate Protection Class IP54 / IP65 Standards IEC 61439, IS 8623, IEC 60364 Applications Residential and commercial solar systems On-grid and hybrid inverter systems Small to large-scale PV plants 📦 3. Solar Junction Box (Module-Level or Array-Level) Product Overview A Solar Junction Box is mounted on the back of a PV module or used externally to consolidate connections and protect the electrical output. It connects PV cells to the external DC cabling with bypass diodes and weatherproof housing. Key Features Built-in bypass diodes for module protection UV-resistant, waterproof enclosures Secure MC4 or equivalent connectors Flame-retardant construction Available for string-level or array-level applications Typical Specifications Parameter Value Rated Voltage Up to 1500V DC Current Capacity 10A to 30A (per diode) Protection Class IP67 / IP68 Cable Gland Support 4mm² to 6mm² cables Diodes High-efficiency Schottky bypass diodes Standards IEC 62790, UL 3730 Applications PV modules and arrays Off-grid and rooftop installations Harsh outdoor environments 🛡️ Why Choose Our Boxes?
