In wiring our trailer our goal was to cluster the key elements as close to each other as possible to minimize wire voltage drop.
I installed our PD 35 amp Converter and 1200 watt Inverter in our trailer. They are both under the front couch, really close to the battery
and beside each other. The wires run from the battery
to the converter and jump from converter to inverter, an attempt to keep everything as short as possible, actually about 2 feet of wire from Converter to battery.
The wires from the roof top solar panel
have a short run to the solar controller. The controller is located near the roof over the couch. From the Solar controller it's a short run to the output of the Converter. Solar charging of the battery uses the same heavy wire the converter uses to charge the battery.
The reality is we rarely use the 1200 watt inverter, just too much power. Instead we have a number of small inverters. Our most common Inverter application is run the TV and sat dish. They use aout 50 watts together and easily run off one 150 watt cigarette lighter type inverter.
To support the 12 volt devices like the small inverter, wifi hotspot, and Endless Breeze fan, we have four 12 volt outlets spread thru our Scamp
We have 9 AC outlets pairs. Three of the outlets have USB charging ports (6 USB charging ports in total, that handle charging our Tablet, phones and Nooks) when we're hooked to AC.
We also carry a 150 watt inverter in the car. We can use it to charge our computer as we drive, useful if we're going into boondock. We also have USB ports in the car to charge our phones as we drive. Our computer is a netbook and uses very little power, when new it would run for 8 hours without recharge.
Like many we have 3 ways to charge our battery, from our 80 watt solar panel
, from our tow vehicle and from our PD Converter. We typically only charge from the car (switch selectable) when it's a rainy or overcast day since the solar charges on sunny days nicely as we drive.
We have enhanced our lighting
going to all LEDs, no 120VAC lights
at all. Our Scamp
came with 4 incandescent lights
and one fluorescent light
on the inside. We have added four additional LED lamps (2 of them LED spots) and replaced the fluorescent with a LED Bar. In addition two of the more heavily used LED Lamps have double LED bulbs to provide twice the illumination. Of course we rarely light
all the lamps but as we age like a lot of light/contrast where we're reading hence the double bulbed fixtures.
The next electrical
upgrade we contemplate is a Trojan 12 volt battery to replace our group 24 battery.
The only thing I would do different is not include the big Inverter since we rarely use it.
