I am having problems with my Victron Multiplus 12/3000/120-50
(230V/240V) that is installed on a sailboat. Please forgive my detailed
description, but I am presently at my sailboat in Raiatea, French
Polynesia, and I have only limited, once per day, Internet access.
I installed the charger/inverter (I will use the name "Multiplus" in
this message, but I mean "Victron Multiplus 12/3000/120-50 (230V/240V)";
this is only for brevity) in October 2019, pre-Covid. I have only this
week been able to return to Raiatea from my home in the USA. When I
installed the Multiplus in October, 2019, I tested it thoroughly, and it
appeared to work perfectly. When I applied 230 VAC to the AC In
terminals, I was able to measure and use 230 VAC at the AC Out
terminals. The inverter worked as specified and the batteries were able
to be charged.
When I returned to my boat this week, I applied 230 VAC to the AC In
terminals, but there was ZERO VOLTS on the AC Out terminals, regardless
of the position of the rocker switch. When I turn the rocker switch to
"On", about 100 to 200 milliseconds later, I hear a faint "click" coming
from the top right corner of the Multiplus. I do NOT hear a clock
coming from the bottom left corner, where the AC In connectors are.
When I turn the rocker switch to "On" (not to "Charger Only"), the Mains
On light DOES NOT illuminate, but the Bulk, Absorption, and Float LEDs
flash yellow. In addition, the Inverter LED flashes green, alternately
with the Bulk, Absorption, and Float LEDs. (The actual Bulk,
Absorption, and Float LED flash pattern is a little more complex than I
indicated, but I cannot figure out how to attach a short video to illustrate the
pattern precisely.)
As far as I know, nobody has touched the AC circuitry on my boat since I
installed the Multiplus on October 2019. I fervently hope that some
Victron service person reads this message and can advise me. This is a
pretty expensive piece of equipment to have failed after virtually no
use whatsoever.
Hopefully,
Jim Melton
