How are you
my inverter brand OREX 3KVA 60A MPPT, start up showing error 57 which means current sensor failure!
any idea about this error and how to be solved?
You can indicate to any element, so I will send you clear photo of them, some of the MOSFETS has been tested or totally changed!! But I didn't get any positive results until now
your comment is exactly the same the vendor reply when I asked them about the meaning of error 55 description (over DC voltage in AC output) they said: Check the BUS synchronous rectification MOS and related the drive circuit!! can you help me how to check this circuit!? if you need any pictures...
the problem not in the refrigerator it self, because i tried many types of load, the problem not in the load type but in load volume, regarding the error 55 means is over dc voltage in ac output! which means the wave is deformed, the question is why the wave is been pure sine wave with small...
How are you
My 3KVA inverter is pure sine wave showing error 55 which means high DC voltage in AC output or unbalanced voltage
what would be the problem!!?
