How to fix PM isolation LT error on REFU REFUsol 17K?
If your REFU Inverter shows a PM isolation LT error, it means the power section detects an isolation error on activation. Check system isolation. If you consider the isolation resistance to be in order, contact Service.
What does Keep Alive mean on REFU REFUsol 17K?
If your REFU Inverter displays Keep Alive error, it means internal communication monitoring has determined a fault. Please contact Service.
What to do if REFU Inverter displays SR parameter error?
If your REFU Inverter displays an SR parameter error, it signifies an error in parameter initialization, and the device has been permanently shut down. Please contact Service.
What to do if REFU REFUsol 17K Inverter showing update fault?
If your REFU Inverter displays an update fault, it means the update has failed. Contact Service.
What to do if REFU REFUsol 17K shows Supply voltage LT error?
If your REFU Inverter displays a Supply voltage LT error, it means the supply voltage at the power section is too low. Please contact Service.
What does Activation LT 4 mean on REFU REFUsol 17K?
If your REFU Inverter displays Activation LT 4 error, it means balancing has failed. Please contact Service.
How to resolve Initialisation C1 error on REFU Inverter?
If your REFU Inverter displays an Initialisation C1 error, restart the inverter. If this does not rectify the error, contact Service.
What to do if REFU REFUsol 17K Inverter shows DC-voltage measurement error?
If your REFU Inverter displays a DC-voltage measurement error (DC link 3), wait for the measurements to become stable again. If this takes more than 2-3 hours, please contact Service.
What does Communication LT mean on REFU REFUsol 17K?
If your REFU Inverter shows Communication LT error, it means there is a communication malfunction between the power section and the control and regulation unit. The inverter will acknowledge the error automatically. If the problem occurs repeatedly, contact Service.
What to do if REFU Inverter shows RCD fault?
If the AFI-Board unit in your REFU Inverter detects a residual current, it will lead to an immediate shutdown. Check the system isolation. If you believe the isolation impedance is fine, contact Service.
