In 2010, I bought a Quattro 12/3000.
I’ve had to replace the Mainboardwith using Lithium Batteries.
For the past two Weeks, it hasn’t been charging the Lithium Batteries anymore.
It started having Problems with the Voltage at the Marina (dropping as low as 170V).
What could be the problem?
Thanks for your feedback.
Kind regards
Did you reprogram it?
..no it was just stopping the charge.
If the system was repaired it would return with default settings. If you did not reprogram it, it is unlikely to work correctly.
If English isn’t your first language we have an other languages section that may be more helpful.
Is it not Problem with the Input Voltage? (down 177V)
Not enough to go on here.
The LED status should tell you if it is mains connected or not.
How has it been configured? What is the grid code and voltage cutoff thresholds?
These all need to be configured, as does a weak grid.
If you have a repaired system all config is lost to defaults so if you have not set it up, it is unlikely to work properly.
Would suggest you get a professional to assist you.
170 or 177v is out of the default acceptable range which is usually 180v.
So it is likely it is rejecting mains.
But what really needs to be checked is if it is actually 177v with a good multimeter.
Maybe get the mariner to check there are no loose connections and such in your connection point.
And also on your set up.
I’m in the Puerto Williams … at the End of the World…there is nothing to change…The Power is messured with a Fluke…
What happens when the Voltage under 180V
The inverter disconnects its input relays
If you need to charge from lower voltage, use a phoenix ip43, it has a massive input range.
