4.Specifications and attention-Attention
In my experiment, encountered some problems, and share 5 tips with you:
Tip1. It is different with the inverter, RU600 require real-time monitoring of the
grid voltage.If it shows “LP”,after power on ,firstly check the grid voltage
detection line wiring is properly connected to the grid.
Tip2. When using an external inductor,grid detection wire needs to be
connected to the grid side.
Tip3. Energy feedback unit and inverter applications in parallel mode, need to
use Commonmode Choke in series with the bus, or will cause circulation,
affecting the normal use.
Tip4. Power normal, keyboard display properly on RU600, but the bus voltage
and bus voltage of the inverter are inconsistent, to confirm the internal fuse is
damaged or not.
Tip5. It is different from the inverter, losing uncontrolled rectifier bridge ,
increasing the grid voltage detection circuit, so we can handle the rest of the
abnormal as the inverter.
