No I am not sure about type of wires, I have no knowledge in electrical components. Will get an electrician to try and sort it out
-
Sorry, solar are connected to battery. All equipment is connected to fusebox Problem increased, after 3 hrs use the fridge surpassed 8.5amps and could feel the wire quite hot! Definitely not leaving it on overnight
-
Thanks. To correct my last statement I connected the clampmeter wrong at the fusebox...checked again the values are the same around 6.9 amps both to fuses and to fridge
-
Perhaps this will help aswell .. just checked right now,m with clamp meter the current flowing into the fusebox through 16mm2 cable is 4.6amp, current flowing into fridge through the 4mm2 cable is 6.7 amp

All my equipment is connected to a fusebox at the back of the helm, nothing connected directly with battery. I had a voltage drop problem but resolved it and also installed a new battery 5 days ago, also I have a smartshunt installed so I can check better against any voltage drop. What I am not understanding is hiw the fridge increases the load over time...the first hour or so it remains approx 4.5amp then increases. Correct me if I am wrong but if there was a voltage drop problem wouldn't this be visible immediately once I switch on fridge?
-
Thanks for info...will definitely check
-
Actual wire length would not surpass 1.2m
-
No not on same wire. Each has a dedicated wire from fusebox. I don't keep it on for security purposes especially due to high temperature...i have seen so many accidents caused by fire locally and almost every time due to electrical faults when boats are unattended
-
Will have an electrician take a look soon. My fusebox area is so cramped up hope fridge wire can be changed if need be.
-
Thanks for info. Definitely helps to understand better from what you are saying. During the day I have no problem with the load as my solar panel can give up to 11amp which compensates for any equipment I have on at anchor. My worry is during the night as I will have the fridge drawing approx 6a, two 12v fans drawing 1.5a each and some occasional lights...which put me near 10a. My battery is 260ah so should resist a full night with this load until the solar kicks in again. Will test the battery leaving it on for 24 hrs with fridge on and see what happens
-
Thanks for the tip. Yes i also thought it would stbailise but seems other way round...hope no damage is done to the fridge

Sorry for the late reply. Installation manual states that for up to 4 metres round circuit wire from fusebox to fridge wire should be 4mm2 as I have. This was installed by the factory itself, the boat is a beneteau antares 9 2021. I always checked voltage with engine off, even with solar panel disconnected and I didn't find any voltage drop of note..only about 0.1v. The thing about current measurement is it seems to be increasing by time. For example today as soon as I turned on fridge it was 2.7amp, after an hour or so went up to 4.5amp, after another hour 5.4amp and last I checked after another hour it measured 6.2amp with a clamp meter
-
Yes have measured it and it is exactly as battery measurement way over 12v
-
I am having some doubts now that the fridge needs some maintenance but it does cool down from around 35 degrees to set temperature of 9 degrees in hot Mediterranean weather in about 2 hours which I think is fairly good. My concern is whether using 6+ amps for this is acceptable or not especially since it is rated at max 5.5 amps. If not, the problem could be related to the gas loss you mentioned?
-
Forgot to mention that battery is 260ah agm and have a 200w solar panel with mppt. The wiring from the fusebox to the fridge (about 1 metre away) is 4mm as recommended by maker
-
Battery is brand new, wiring thickened to eliminate voltage drop. Fridge works fine gets cold as should be and no problems in that regard. I cannot leave it constantly on as I keep the boat on a buoy not in a marina...so for safety/security i keep mains off when not onboard. What do you think the problem is?
-
Thanks for the info. I indeed had a voltage drop problem but beefed up the supply wiring from main switches to fusebox and voltage drop resolved. The 6+ amp load was recorded with battery hooked to 200w panel fully charged at 13.4v... still perhaps normal to have the 6 amp load?
-
I have a dometic crx65 fridge installed in my boat from 2021. Recently I checked with suppliers and directly with dometic that since I never keep it constantly on more than 8-10 hours ( and I switch off main switches every time I get off the boat), the compressor will take anywhere between 12 and 24 to stabilise and cut off the first time (also my ambient temperature is always 30+ degrees). However, I have also noticed that although it is listed to use 5.5amps, I am finding the fridge frequently consuming between 6 and 6.5 amps. Is this normal in the scenario I explained or does the fridge need some maintenance? Thanks
