Its been a hectic while since I got the power system up and running, but I want to take a moment to share the split AC/DC system I designed for the house:
I’ve learned a lot on this one. The power system was devised after I spent a few weeks looking at the power options available to me at the big box building stores. All of them didn’t really seem to fit what you need to have for a comfortable life in the tiny house. Having ample lighting and power in the tiny house will make life in this tiny space much more enjoyable. Thoughtful light and power placement seems to me to be very important in designing a comfortable living space. This setup allows me to accomplish all of those needs in a nice easy package.
As I mentioned in the previous post, the system is designed around two BlueSea marine grade power distribution panels. It has an integrated AC/DC converter that provides 45Amps of power for the DC service. It has 16 DC circuits and 10 available AC circuits that are easy to connect and because each device is on its own circuit, simple to install.
Once the Power unit was installed, it was only a matter of connecting the system to the main power in and attaching the circuit runs. The main service for the system is 30Amps, this should be enough to run most things needed in the tiny house. Its also set up to be able to receive its power from a standard outdoor outlet for greater adaptability. The DC service is great for running things like lights, fans, and high efficiency refrigerators. The AC service is aimed at running luxury items, like the air conditioner and washer-dryer combo. The house can also run all of the DC service off of a battery bank that will be located in the tongue box. I think integration with solar in the future shouldn’t be too difficult, I have installed DC bus bars that allow for easy addition to the system. Right now, the system has been on and running for about 2 months now, running tools, lights, fans and my 12v refrigerator. The power unit has been stable and the system has been able to keep up with everything I’ve thrown at it. Glad to have this one sorted out.
In the last week, I have been installing the plumbing system and designing a new plumbing unit for the house. I am planning to do a write up in the next week or so on how to install PEX plumbing and sharing a system I have built. As always, feel free to ask questions, suggest changes to my designs or just say Hi!
Till then Tinyhousers,
