eco-DCCH AC control hub

eco-ACCH is special designed for grid-connected photovoltaic system. It provides all necessary functions between grid-connected inverter output to customer distribution board.


AC Circuit Breaking Protection -

Equip with double/4-polecircuit breaker 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 gridinverter from the PVarray.

AC power signal measurement-

Transducers are built-into measure the AC current and AC voltage ofeach phase. The output signals can be integrated into our performance monitoring system model, 'eco-PMS' and display monitor for real time monitoring at site.

Manual grid resume timesetting-

Users can set their owngrid resuming time after AC fault in order to suit utility requirements.
