Quatroo 48/15000/200 - electric car charging problem

Quatroo 48/15000/200 - electric car charging problem.

When installing 1 phase 230V 50Hz Poland, a problem pops up on the electric car charger. 2.3kW 230V charger. Doesn't charge the car. How to set up Quatroo? Please help. Other loads work, lighting, heater. Only the charging of the electric car does not work. Charging error pops up on car charger.

That explains it. At least glad you got it working.

@mateusz. So if I understand correctly, you have a quattro inverter 48/15000/200 connected to your grid, and on the quattro output you have a single phase car charger installed ?

  1. yes I have a 48/15000/200 off grid inverter. On output out1 all devices work. Only the original BMW charger 1 phase 230V 50hz, 2.3kW does not work. A charging error pops up on the BMW charger. Do I need to set something on GX Control to DVCC?
  2. The original BMW 2.3kW charger works when I connect it to the mains - it charges the car. It doesn't work only when I connect to Quatro to output out1. On the BMW charger it shows a charging error.

@mateusz. When you only connect your other loads to the inverter, do they draw aprox. the same amount of current as your car-charger and keep running ?

Other devices connected consume 5kW-8kW and quatroo works. The BMW charger consumes 2.3kW and does not work.

Maybe your EV charger has a problem with the input voltage/frequency. Could you check if your Quattro is set to search-mode. Try and turn this "off". I would also try to turn the "AES" off, and see if you can get your EV charger to start.

Where to put Quatroo into search mode? Now Quatro is set to 50hz in accordance with Poland. AES is disabled.

I connected to Quatroo MK3 cable, quatroo output is 49.9-50.1 hz. The BMW charger works at 50hz, is that a problem?

Did you try what I mentioned before ? Quote: Maybe your EV charger has a problem with the input voltage/frequency. Could you check if your Quattro is set to search-mode. Try and turn this "off". I would also try to turn the "AES" off, and see if you can get your EV charger to start.

Search mode is part of AES, if you have that already disabled, that's not the cause of your issue.

@Lucian Popescu (Victron Energy Staff) any suggestions for this member, considering you are the EV guru :)

@mateusz. Did you already try to turn AES "off", and did this solve the problem with the EV charger ?

P.s. If turning AES to "Off" does not solve the problem you could also check the following. I don't know your situation, but are you using an extension cord from Quattro to EV charger ? Since resistive loads work on the inverter as you mentioned, an EV charger has a failsafe for under-voltage and produces an error. Most extension cords only do 1400 watts, and at startup, the voltage might be to low for the EV charger to start.

Thanks @nickdb :)

Make sure ground connection is there. Also, make sure Line and neutral are not swapped, try rotating the plug if it's possible and test again. Charging stations are sensitive to that.
The last step is replacing it with a Victron Charging station (joking)
