Just my 2 bits...
Calculate the total DC load you are going to use in your trailer before buying a DC converter. First I will state the bigger the better, but most smaller trailers do not have a high DC (12volt) demand. Basic items such as lights
and water pump are the main loads. The exception is a 12volt fridge
which I would not use (propane instead) as it draws a lot of current. With my experience a converter putting out more than 10 amps is far more than is required and typically most units come with a converter that will put out 2 to 5 amps on a good day. The largest current load which I find causes problems is the lights
(wife and young kids) being left on.
has a volt amps rating (78 amp/hour ?) which is what you need to consider if fast charging is required. This is how much current is required in an hour so 78amp/hour would take 1 hour to charge or 39 amps for 2 hours etc.A couple things to consider: do you plug in to 115Volt AC and your vehicle driving time. The converter is usually used for turning AC to DC and if you are doing this then you have power so DC will not be a huge concern. If plugged into the vehicle 35amps plus is available to the trailer which would charge in 2 hours assuming 70amp/hour battery
. The vehicle is typically directly wired to the trailer and uses the alternator regulator to control the voltage and current demand. Biggest issue is the length of wire run from vehicle power source to trailer and size of wire as there is larger resistance in smaller gauge wire.
Any substitute charging such as solar
panels will typically be less than 7amps unless you go really serious and will easily keep a battery
Where I have seen problems requiring a larger converter is if charging off a generator
and you want to run it for a short period. In this case go big with the converter.
