It will be interesting to see how the Victron 12/1200 behaves on the next build.
I reckon initially they are 'tighter'. I don't know if it is the same kind of thing but in the olden days (circa late 1980's) the first miniaturised computer hard drives (talking 5.25" and 3.5") used to suffer from stiction and needed a jolt to get spinning from stationary and they tended to be ok later on (We used to build the small 20MB jobbies Alan Sugar used in the Amstrad 1640 PCs)I wonder if the compressors do loosen up, amazingly even on eco it has not stalled anything like as much as it was initially whilst connected to my small Victron and even under my carport the solar panels are replenishing the batteries every day.
So far so good other than than damn buzz!
I guess to a degree that inefficiency does not matter too much when the cost per kW is what 15p or so? I wonder if you might actually be better off with the CTEK when away on site hookup in case you have to pay OTT rates per kilowatt?Ah mains chargers bring something else the equation my Ambulance came with 2 Votronic 30A duo chargers (yep it originally had five batteries and four different 12v systems) these on face value are brilliant, highly configurable, rugged etc designed for permanent use everyday etc but....
They are dreadfully inefficient, when not actually charging anything they draw about 25 to 30w constantly I have kept one of them for use on mains hookup when away but at home I use my Ctek instead which only draws 3w at idle.
need something I removed all the contents for the defrost and the three bottles of water under the ice box were frozen solid.Sounds like its time to fit a locking screw of some sort to the thermostat knob ?
I love having a small icebox in the fridge Out on a day trip on Friday (bit of Tomahawk throwing, pistol shooting and archery) and went back to the camper for a late lunch and filled the glasses with ice cubes for some chilled ciderWe don't use a fridge with an ice box, for the amount of time we are away from shops the extra space is better for us. Mind you, I do get told of if I've got it too cold and start to freeze things. Since fitting cooling fans in the fridge cooling vent our on times do seem shorter.

I get where you are coming from here and I do agree generally.I am seriously impressed with the functionality of the multiplus on paper, but it's that eggs thing. At least with stand alone devices you may be able to mix and match in the event of trouble. That said, for those that are unable or willing to fiddle with stuff it might be a better answer to have only one part to swap out.
Good question and I actually double-checked this the other day The answer is no According to the manual the main DC charging output is configurable to a few options, such as 14.1V, 14.4V (or their 24V equivalents) and the 1A trickle charge for the starter which is at "a slightly lower voltage" (I am guessing the 'slightly lower voltage' is based on the starter battery assumed to be a Wet Cell Battery so usually wanting less)As you've actually played with one Dave, I notice there is a 1amp supply to hold the engine battery up. Is that adjustable between 12 and 24volts? For example I have 12 volt habitation and 24 volts in the base vehicle.
around 500W is around right if the charger is at full pelt. You could use that generator to provide all the neccessary power for battery charging.Ok then Dave, thinking aloud about a Multiplus 12/800/35
35amp battery charger, I guess it's AC demand would be around 0.5kW? So my noisy silent inverter generators 900Watt output should be enough?
700Watts of inverter output you mention was unhappy starting your fridge. Does the overload warning require any user intervention?
I guess if I really wanted too, I could use the 1 amp output through a DC DC converter to get it up around 28 volts at 400 or so milliamps. (would it be worth it) Bigger mercs suffer from constant battery drain that I've never been able to find all the loads.
How much other kit is required to use it? The cost of stand along devices is only around £50 is using the VE stuff.
Connectivity, I assume it's not Bluetooth? Can you play around with the settings as you can with other Victron stuff if connecting with a Dongle?
The engine start batteries will be charged with a couple of Victron 12/15 chargers, I have one and I like how it works.
These batteries also run the internal lighting and will have a 1200 watt inverter connected to them also.
This effectively doubling up allows some redundancy if I have problems.
Each system can run each other if needed.
I tried the Multiplus 500 and it did the same thing as the Phoenix 500 Inverter - Buzz on load, overload light came on for a second and then went off and fridge running nicely.I had the "buzz" on the 12/500 Phoenix Inverter.
The 12/800/35 Multiplus device gave an 'overload' warning each time the fridge came on due to the in-rush but I can't remember if anything physical was noticed - it was only used for a short time as a test unit really.
So in the next day or two I will be doing another test which is combining the two styles of unit - namely a Victron Multiplus 12/500/20 which is arriving today and which I want to configure and test before sending it on to the customer - and running a Compressor Fridge will be a good test for the unit and also be interesting how it reacts to the overload (warning report only or something more physical/audible?). I am expecting a similar result to the 12/500 Inverter but maybe the different overall design has changed this?
