RCT MP-T1000S Power Trolley - high voltage alarm question


Recommended Posts

Posted

Has anybody else have experience with one of these.

We recently purchased one and it just keeps on beeping (4 beep silence - 4 beeps silence ...all the time) as soon as load shedding kicks in and it switches from mains supply to battery supply. Surely inverters should not continuously beep after switching to battery power mode. Its brand new.

The manual says 4 beeps = Battery pack high voltage alarm  (which I would imagine is an warning alarm, of possibly faulty float charging? )

One cant make any changes on the charger side of this inverter - its all preset by the unit. Not accessible to the user.

I have purchased the same unit. You can silence the beeps. Press and hold the Function key for 1 second till you see an icon that looks like a speaker crossed out.

2 days ago I bought the rct 1 kvwa inverter and twice now I have had the alarm go off where it beeps contniously of 4 times in 1 second (so basically rapid beeping non stop). This happens at random times. I currently do not have anything (appliances) plugged into the inverter and just have it plugged into the power outlet for charging. Any ideas what could be causing the voltage overload alarm to trigger?

I have a Mecer unit, with that exact page in the manual. Except I get 3 quick beeps once every few hours. I'm not able to determine what it is, it's not affecting anything, no error message/LED. 

Buzzer is on silent, yet still it beeps. Doesn't really bother me, but I'd love to know what it is.

As you describe the alarm that is normal 4 beeps silence the unit is in  battery mode, 4 beeps in one second continues is battery over volt.

What is the cause of overvolt, and how can it be resolved.?
