eco-DCCH DC control hub

eco-DCCH is special designed for grid-connected photovoltaic system. It combines maximum three PV strings into one and provides manual connect/disconnect from PV array to the inverter and many other useful functions.


DC circuit breaking and protection -

Equip with a double pole circuit breaker special for DC current to protect the PV system components from the risk of overload or fault current of electrical system. If the overcurrent is detected, the built in circult breaker will be activated and immediately cut off the grid inverter from the PVarray.

DC power signal measurement-

Transducers are built-in to measure the DC current and DC voltage of each PV string. The analogue output signals can be integrated into our performance monitoring system model, 'ECO-PMS' and display monitor for real time monitoring at site.

Easy and quick installation-

The control hub equipped with weather-proof PV plug sockets for both incoming and outgoing cables. Thix allows quick, safe and professional cable connections and easy-handling for maintenance personnel
