A Solar ACDB (AC Distribution Board) is installed between the inverter and the load or grid connection to isolate, protect, and monitor the inverter output. It can combine multiple string inverters onto a common busbar and provides a safe and convenient switching point for operation and maintenance. A Solar DCDB (DC Distribution Board), also known as an array junction box or string combiner box, collects power from multiple PV strings and provides protection through gPV fuses, Type 1+2 surge protection devices, and DC isolators before supplying the inverter.
Neo Hi Tech Power manufactures Solar ACDB and DCDB panels in robust IP65 enclosures, designed according to IEC 61439 and configured for specific solar power applications. These panels are suitable for rooftop solar installations, ground-mounted solar plants, and large-scale MW solar projects, providing reliable protection, isolation, and efficient power distribution throughout the solar electrical system.
