OK, laymans inspection
yesterday indicates they are shot.
I flicked off shore power
, turned some knobs at the board, turned on inverter
down near the battery bank and the car stereo and led lights
all worked but 240v was dead.
Not sure if there was another mystery switch I should have flicked somewhere, it wouldn't surprise me if there was.
Battery indicator in the switch-panel at the helm
showed volts in the green, but amps barely registered. flicking between the 1,2,3 positions did nothing
Amps on the big switch panel below also registered nothing worth noting.
System currently has 6 x 200ah 12vagm's hooked up to make a 600ah 24v bank being charged by a Victron Skylla 24v/50a via an 8kva genset - the picture below is with shore power turned on.
That was supposedly able to run a near 550litre (19.5cf)samsung 240v fridge freezer/icemaker, a separate small bar/bait fridge (there are an additional bar fridge and same size freezer
as well currently turned off) and an 80 litre 240v HWS .
There will be a few hours a day of 40inch LED tv use and occasional pumps for taps, sani loo toilet, electric
kettle twice a day and some led light usage as well as anchor
light at night and a sounder.
Additional items like the 240 v washer and drier would be used when the genset is running.
I find it hard to believe that the battery bank was sized correctly for that sort of load, I may be wrong and my research
indicates that the Skylla was barely capable of charging
that bank and if wanting to add some more batts I would have to get another charger
to compliment the one it has.
As the boat has a large flat roof I plan on dumping a pile of panels
on the roof to cut back on genset usage.
I can currently get a tier 1 brand of 250a x 10 12v for $1500 so that'd probably be a nice start running through an 80a outback or similar mppt
Any advise on bank sizing, battery brand, charger
requirements would be appreciated.
Thinking I am possibly going to dropping the quick $10 k on an upgrade here.
