Hi,
I'm facing a Quattro (5kw / 230V / 12V) which will not start up. The batteries are low (17.6 %)
It just cycles through this sequnce:
- All LEDs dark
- Green LED Mains on flashing
- Green LED Mains on going steady and Float lighting up for a very short time (< 1 Second), sound of relay audible.
- Go to 1 and repeat
What I did for troubleshuting:
- Measured mains voltage at AC-In of Quattro: 233V not going down during startup.
- Measured battery voltage at the batteries and on the connections of the Quattro. The same voltage (12.69V).
- Removed AC out wiring from AC out 1 (AC out 2 not connected). No change.
The system was in operation for over four years, so I assume that configuration is correct.
Any hints?
Thanks in advance
Tomy
