We are in Togo WEST Affrica ! Our Quattro Inverter 48 Volt/10000/140AMP flashing Low Battery . When we plugged the MK3 USB, It also says 5 volts is coming in but we do know that it is the 55 V that the battery is showing that is coming in! We measured it ! we tried many things but the system is not working. Are ther any advices on the programming as well? In our system we do have :

  • 25 Solar panels
  • The inverter
  • the charger MPPT RS /450 / 200
  • THE EKRANO
  • 2 BATTERIES EG4
  • The Grid

PLEASE WHAT TO DO NOW? Please I need help!

Not a solution but a question: Did you measure 55V on the Quattro terminals?

3

As above, do check the voltage on the battery terminals of the Quatro, also all batteries, cables and fuses in the system.

Yes, I did measure the 55 V on the quattro terminal!

5

The voltage are 55v on both EG4 Batteries!

I did not have fuses in the system!

Do you still see the Quatro on the Erkano monitor? Go to ‘devices’ and see if there is a remove disconnected devices button. If so press it and see if the Quatro is connected or not. Seems likely that you will need a new one / repair.

Also, please remember to put fuses of appropriate size in the +ve feeds from the battery to protect the equipment & cables.

I had a similar error. It turned out my quattro had a problem. The entire board had to be replaced. Make sure you have done the pre-rma bench test to the extent possible. A Victron dealer can do it for you: https://www.victronenergy.com/upload/documents/Pre-RMA_bench_test_instructions/114199-Pre-RMA_bench_test_instructions-pdf-en.pdf
