Must be some strange current in the air.
You seem the have a problem in your controller if the solar array is reading 0.
Simple first check. In sunlight, put a multi meter on the + & - wires on the SOLAR wires at the bottom left of the controller. No reading then the problem is in the wiring coming in. Or panels but all 3 most unlikely. even dud panels usually have something.
if you get a reading then the controller is the problem. Throw it out. For $280 odd it's not worth mucking around with.
You are really pushing your system with only 2 batteries. if they are old (how old) they may have kacked it after they were load tested from being on their own (doubtful) but you definitely need 3 batteries to run your system if your not on power or don't want to run your genny every night.
Did someone say something about a Toaster.??? On an Inverter. ??????????????
We have a power loss problem that is baffling me too.
Power holds up fine as per usual down to 12.5v then zonk ! you can see it dropping to 11.8v cut out.
This is a new one one me.
We've had our 10 yr old van 6 years now and have replaced 3 Ky panels, yes found the culprits 1 at a time by covering them individually and watching the read outs. Ky replaced them under warranty ok but we had to pay the freight.and we've been thru 2 sets of batteries, the originals and a set of BT "specials" that lasted 2.5 years. We run a lot on "off power"and rarely use the 20i to top up battery charge.
We have 3 panels and 3 100a/h Supercharge (not by choice) AGM's 18mths old.
Normally it handles our 190l fridge at 2.8 amp. (had the blue resistor taken off by a fridge mechanic in Hedland 2 years ago & halved the draw) and 1200w inverter and 3-4 hours of tv/dvd per night easily,--
Down to 12.2v by morning in up to 35degree. days.
temps above that we cut back to 3 hr max tv. maybe none over 40 deg.days.
i agree Mother Hen, Batteries first on the list.
First check the batteries, Is one getting hot ? (that does not always happen)
As some has already said, the dud battery will be draining the others.
This is my next check. It saves taking all the batteries out or having to find a battery mob in the middle of Woop-Woop or with parking for a rig.
Disconnect each battery in turn each night, (in the evening) only have to take off the Neg.
Put any wires to another neg in the set.
run the van as usual overnight. if that battery off improved you power time, then that one's the problem.
if that battery is good your power will drop even faster.
Take that one to a battery dealer and have it load tested. If you can' have it tested strait away, leave it out of the system.
My trouble now is that the above has not shown a dud battery.
My solar in is fine, my fridge is running it's normal 70% cycle (now the Perth temps have come down. ( I hoped it may have been the long hot was the problem)
I checked the inverter(by not running it below 12.6v) Still dropped out at 12.5v
I turned off the fridge one night at 12.6 v. and thats where it was in the morning , proving there was no "leak"
I have turned the inverter/tv off at 12.8v at night and left the fridge going and still have 12.6v in the morning. proving the fridge would appear ok.
Tomorrow my last resort is to take out all 3 batterys & have them load tested (to the max)
then if they're ok i'll get a new controller or if not 3 new Full River batteries and find a job sooner than planned.
Expect to and it is preferable to replace all batteries together.
Twice i have sold my other still ok 2 batteries to campers etc for $50 each / no garantees or course.
Aah ----- Batteries / Power *&%#2****

Escape 1, you said your solar is showing 0,
I've just been reading my prostar manual (properly) and 0 means either the reset button has been pushed for 2 seconds to turn the solar off -- or it has cut off due to a fault in the solar system.
a check on the solar panel wires at the prostar box with a multi meter should show if there is anything coming in.
that the solar is not charging your batts says to me that it's not getting to the prostar or thru the prostar or your batts are too far gone to accept charge.
OR ---- as I am beginning to strongly suspect in my case, the prostar is faulty.
i had all my batteries tested today and they are fine.
I can have the prostar tested here in perth by the 12volt shop for $20 but it'll take 3 days but i have yet to find out if my fridge, lights, pumps etc will run if i take it off.
