MGE Galaxy 7000 ,300 KVA UPS DC Bus Fault

[BillP]

In our MGE Galaxy 7000 ,300 KVA UPS  goes to by-pass automatically.

Normal Power Green Color LED not glowing and Red color glowing there.

DC Bus Fault

DC Bus Voltage fault

DC Bus unbalance.

What could be reason?

DC Capacitors are inspected and Each capacitor 3900 Micro Farad.

By using multi-meter capacitors values are measured and found the values between 3400 to 3800 Micro Farad.

Is it the DC capacitors faulty or any other reason ??

Thanks
