Electrical system upgrade

Since is has been so long since I have done a proper update I'll summarizing the updates to each system.

Back in August I was running a 2500 watt 12v inverter, 2 x 200 watt solar panels and a cheap charge controller.  I was having to run the generator a couple of hours a day to keep the batteries from going dead with minimal use of electricity.

I put in my order for my new solar system in September.  I was excited and nervous, it was awesome.  I've been researching and waiting for over a decade to have a off grid system and it was finally happening.  I was nervous because it was going to be $7,000.

The first thing to arrive was the charge controller which would allow me to run the panels at over 100 volts and the battery bank at 48 volts.  Shortly after receiving the charge controller I sold the inverter for a nice profit but I had to make do for a few weeks with a cheap inverter.


While waiting for the parts to come in I make another trip to the states for batteries.  It was funny watching the suspension when they dropped the 16 golf cart batteries in the truck bed.

More power!

The wrong panel for the inverter came in so I had to wait a another week for it to come in but that gave me time to order cables for the new panels.  Once the cables and proper electrical panel arrived I got to work installing them.  The new inverter gives me 4400 watts at 240 volts, more than I'll need.  The electrical panel handles the DC breakers and main AC breakers, including inverter bypass.


The batteries will be tucked under the cabinetry so I needed a way to pull them out for maintenance.  I made two skate boards for them to sit on




6 of the 9 panels @ 250 watts each.  I've been using the solar setup most of the winter.  My generator has not been used since the fall.  On cloudy days I make 1 to 2 KWh and over 10KWh on sunny days.  I've stopped using propane to heat my water because I produce so much electricity.


Just recently I installed and wired the AC breaker box.  I'm pretty happy with the job I did.  I just have a few more circuits to add and it needs to be permanently installed once the cabinetry is done.

So its been two months...


The tiny house has been on the back burner for the last couple of months.  I decided to focus on school and pretty much everything else was put on the back burner.  The last two weeks I've been off so I've put a lot more time into the house and I have a few tasks nearing completion so there should be some big changes in the next few weeks.

I have still accomplished a few things while in school.  The bay window is almost done.  It have wiring, sheathing, insulation and vapour barrier done.  With wiring passing through the bay window I have also been able to finish the wiring and insulation on the last wall.

The vapour barrier on the north wall is mostly done.  I just have to pass a few more wires thru it before I can finish.

The windows have mostly arrived.  There was no packing during shipping so some of the screens where damages.  I have to make another trip to the states to pick up the last 3.

I found a store locally that has roofing for the same price as in the states.  They have more choice of colours so once that is sorted out then I'll be ordering it.  As a bonus they will cut to length for me.

I've been busy the last week fabricating the brackets for the roof extensions.  I have spent about 16 hours making the 40 brackets but I think the end result will be worth it.


I've been super geeking out over the performance of my solar setup.  It has been producing enough power to keep the welder going without having to run the generator.  At one point the panels where producing over 30A even though they are only rated to produce 22A.  :)

Expenses to date: $17,014

Merry xmas

I hope everyone is having a great xmas!

Ordered the furnace, hot water tank, propane hoses and regulator.  They have been delivered to a shipping outlet just south of the border.  I also ordered and received some LED strip lighting but I was less then impressed so I ordered a different kind.

I bought the inverter that I talked about at the beginning of the month (Magnum MS4448PAE) .  It turns out he ordered it for a project but it fell through.  The seal on the box wasn't even broken.  I saved about $800 plus shipping taxes and duties.  Unfortunately he didn't want the outboard but I did get in running and I'll sell it in the spring.  Now I just need 16 batteries, more solar panels and a better charge controller.  I'll be breaking the cost of the solar system out of the running total due to it heavily skewing the cost of the tiny house.



Now that the sheathing is done I had help from a classmate and a roommate to help put the Typar up.  After about a thousand staples it is securely attached.  I left out a row or two around every opening, this is so i can come back later and flash them.



The threaded rod is installed everywhere. I cleaned out a couple of stores and found out it pays to shop around.  Here is what I paid at each location for 10' lengths (except HD which was 6')

I wish I had known about BC fasteners first, I would have saved about $80.  Granted it would have been a lower quality zinc plating but they will not be exposed to water anyway.



The Strong Ties are installed on almost all the rafters, just the first couple rafters to finish.  I also installed the outriggers for the loft gable end.




The friend that has been lending a hand from time to time was in town so we loaded out her truck with all the scrap wood.  The side and interior are much tidier now.


Expenses to date: $8,924

Technical difficulties

Sorry no pictures this week, I tried to use my old camera and they all came out blurry.

School has kept me pretty busy so I haven't had much extra time.  The forecast contains another cold snap and snow so I had to rejig the tarps.  I still have a small leak in the loft area but I'll put up some plastic to fix that.

Both side walls are 98% covered with sheathing.  I'm hoping to find time to finish them and get the Typar up before it gets cold on Tuesday.  If I can get that done then I can heat the place and start working on the interior until it warms up again in mid December.

As you know I've been looking at inverter since starting this project.  I picked up that ProSine 2500W for a couple of hundred but because it ran off 12v I knew I would be upgrading down the road.  I've been looking at the Magnum MS4448PAE inverter because it has a very unique and handy feature.  It will accept either 120VAC or 240VAC and output 240VAC.  This is important because I want to use split plugs in the kitchen.  The picture shows how a split plug is wired.  This allows 15A to be draw by both plugs for a total of 30A but it can only be done if 240V is being used.  If a 120V system was wired this way it would overload the white wire possibly causing a fire.  Split plugs can be used on a 120V system but ONLY if both sides are split and it would require 4 wires.



So back to the story, a couple of days ago I found a Magnum MS4448PAE in the local classifieds.  It's barely out of the box and comes with the control model.  It gets better too!

About a month after I picked up the trailer the previous owner called me.  She had a long shaft outboard (like for a sail boat) that she wanted gone.  It wasn't running and the cooling pump wasn't working but I picked up up anyway.  I didn't have time to working on it so I just put it in storage.  What does that have to do with the inverter?  Well the guy is looking to trade for a long shaft outboard.  Guess I have some tinkering to do.

More posts coming soon

I'll be soon back to work on the house but here is a little summary of the past 3 weeks.

First, I got a second quote for the SIPs and it was $9000 with taxes in, about the same price as the other quote.  As much as I would like to use SIPs, I can't justify spending and extra 4-5,000 on them.  Now I have to rework the plans to go with a conventional stick build.

Second, I spent 5 days on my motorcycle touring around Washington state and Victoria island.  It was awesome.

Third, I started school!

Finally, I sold my 28 foot toy hauler and had to drive it to Edmonton to meet the buyer.  With school and building the tiny house eating up a lot of cash the sale gives me a good buffer.

Two small updates.  I was given a second induction cook top for free!  I just bought a used 2500 pure sine wave inverter for 225!  Now I can run all the tools off the battery bank.
