Bitdameun Junction Box is designed to install and manage power lines consisting of PV array in an optimum state and monitor electricity in real time to ensure the stability of the photovoltaic power system. It is based on an elegant design which can be applied in urban and public places.

Heat Management
provides an environment optimized for photovoltaic power system, detects and Emits heat with cooling plate tightly coupled to diode
Superior Weather Resistance
with highly weather resistant ASA, the product can be used for a long period of time and is perfect for use in outdoor casing as its color lasts for a long time
Improved Safety of Channel Monitoring System
4000V high voltage insulation with CT and improved safety with the monitoring system designed for low voltage (5V or lower)
Improved Fire Prevention
separate wires are laid for plus and minus without PVC duct to prevent creepage flashover, and heat-resistant glass fiber wire is used for the effective prevention of fires
Smart Error Detection
monitors each channel and display error messages on the window when a failure is detected in the system in order to make error detection and maintenance easier
