. 🔧 ACDB & DCDB for 1 to 5kW Solar PV Systems 🌞 Product Overview The AC Distribution Box (ACDB) and DC Distribution Box (DCDB) are essential safety components in solar power systems. Designed for solar installations ranging from 1 kW to 5 kW, they ensure safe, efficient, and reliable power flow between the solar panels, inverter, battery (if present), and the utility grid or load. These compact, pre-wired units integrate all necessary protection devices including MCBs, SPDs, fuses, and isolators, ensuring protection from overvoltage, short circuits, reverse current, and electrical faults. ⚙️ DCDB (DC Distribution Box) Function: Combines DC inputs from solar panels and routes it safely to the inverter. Typical Features (1 to 5 kW Range) 2 to 4 string input terminals (MC4 compatible) 1000V or 600V DC-rated MCBs High-quality fuse holders with gPV fuses (10A/15A) Surge Protection Device (SPD) – Type II (DC) DC isolator switch for emergency disconnection IP65-rated polycarbonate or powder-coated MS enclosure Sample Technical Specs Parameter Value Max Voltage 600V – 1000V DC Current Rating 10A – 32A per string No. of Inputs 1 to 4 strings No. of Outputs 1 Protection Devices Fuse, SPD, DC Isolator Enclosure Rating IP65 / IP66 ⚡ ACDB (AC Distribution Box) Function: Distributes AC output from inverter to grid or loads and ensures output safety. Typical Features (1 to 5 kW Range) AC MCB or MCCB (based on inverter size) SPD (Type II) for grid-side surge protection ELCB / RCCB (optional) for human protection against leakage currents AC Isolator for safe maintenance Provision for energy meter (optional) Powder-coated MS or polycarbonate weatherproof enclosure Sample Technical Specs Parameter Value Voltage Rating 230V / 415V AC Current Rating 16A – 40A Phases Single-phase or 3-phase Protection Devices MCB, SPD, ELCB (optional) Enclosure Rating IP54 / IP65 ✅ Benefits Ensures electrical safety for system and users Protects expensive equipment (inverter, modules) from surges or faults Complies with MNRE, IEC, and safety standards Pre-wired and tested — quick installation on-site Modular and customizable for rooftop systems 🏠 Applications Rooftop solar homes (1kW–5kW) Small shops, schools, or community centers Hybrid and grid-tied solar systems EV charger-ready homes with solar 🔖 Marketing Tagline “ACDB & DCDB – Safe Solar Power from Panel to Plug.”
