Phoenix inverter 12/500 incorrect output AC voltage

I have installed the Victron Phoenix 12/500 inverter in my camper van, supplied by a new 120AH AGM deep cycle battery.

The inverter is a 230VAC unit (labelled on the box, and on the inverter socket itself)

Prior to connecting loads I checked the output and discovered that it is inverting at 120VAC.

Thinking that it was a programming issue, I purchased the V.E direct Bluetooth dongle. Which showed that the inverter was configured to 230VAC (as it should have been). Adjusting the output range from 210-245 VAC, changed the inverters voltage at the socket from 100VAC to 120VAC . (The dongle didn't allow me to change the VAC range between 230 and 110, only from 210-245)

I plugged a globe into the inverter outlet to determine whether it needed to adjust depending on load to no avail. The light worked but was probably just operating on a low voltage situation.

Is it possible that the wrong transformer was put inside my inverter chassis?

I confirmed that my Meter was accurate by testing 240VAC on a known source. But I wondered if the V-RMS voltage on my Meter worked differently with the different power source? I.e comparing a 12v inverter supply to a street transformer.

Has anyone encountered this before?

I haven't tried the inverter on a different battery as yet. But during testing the battery was reading 13-14 volts and was charged by a 285watt solar panel.

Thanks in advance.

Hello Ethan,

Sorry to hear that.

Several questions:

From where did you procure the Victron 12/500 ,220~240AC Phoenix Inverter?

1) Was it an "open box?"

2) Bought it from a used trader?

3) Got it at a discount Trader?

4) Swap meet?

5) Original Victron Distributor?

Why I asked you :

1) Victron Products are throughly tested 3 times by the QC Dept: before releasing to Sales Dept:

2) Victron labeling never gets wrong. It's totally computerized and chances of Manual error is Nil.

3) The aforesaid item carries a 5 year warranty against any defect. If procured from Victron official

dealer, they'd replace the item at no cost. No questions asked.

Now let's look at the other probabilities. What I script may sound sour, but in reality this often happens in our vicious word. These findings are closely correlated to the above 4 items.

1) Unscrupulous "XYZs" removed the 220~240 AC Toroid Transformer and replaced it with 110~120

AC Toroid Transformer.

2) The whole Circuit board was swapped by the aforesaid "XYZ", with 110~120AC system.

I have often come across reports of such nefarious activities from XYZs, and a few arrests.

Remedy:-

1) Return the item to the seller and obtain refund.

1a) Chances are that you may not be successful.

1b) Do you have a printed receipt, as a proof of procurement? if not.....

1c) It's goodbye to your funds and a bid BLUE CHOKE for your Van

2) If the said item was procured from Victron Distributor, chances are 100%; for a replacement with a

smile.

Ethan, If I exceeded my limits, please do forgive me.

Take care and be safe.
