Happy Thanksgiving!
Check out the new Leak Project Mobile Tour DIY Solar Generator Power Station. With a sleek new Renogy Monocrystalline Foldable 100 watt Panel combined with 3 X 15 watt polycrystalline panels, from Chicago Electric.
Using a heavy duty plastic case and 1000 watt pure sine wave intverter by Xantrex, it also has a 150 amp fuse box, heavy duty cables, new wiring and more.

We power up a 1/3 horsepower metal grinder, house fan, charge a cell phone, laptop, couple car batteries and a couple golf cart batteries.

*Note i made a comment that i thought motorcycle batteries were 6volt because of a faulty battery i’ve attempted to charge. There is both 6volt & 12volt batteries for motorcycles, however most modern bikes run 12volt.

This is my portable power box 2.0 designed to run a 100 watt HF amateur transceiver (or two) nearly indefinitely! Below are the links I promised and some more info I should have included. I’ll add more as I think of it.

The box weighs about 34 pounds, and the hinges/handle/latches don’t seem stressed.

The Solar Array is comprised of 4 Goal Zero Boulder 15 Watt panels

If you have a Costco near you, these panels are generally available from the Costco Roadshow for $99 each. To find when the Goal Zero roadshow will be visiting a Costco near you, visit:

The battery box is built using an MTM Sportsmans Plus Utility Dry Box (The SPUD6). This box is nearly ideal because it is significantly less expensive than a Pelican, it has an o-ring around the lid seal, both lids overhang the edges of the compartments they cover, and it includes a removable tray. This box can be purchased from Amazon and more information about this box can be found here:

To provide power distribution from the box to devices, I am utilizing a West Mountain Radio RigRunner 4004USB. This power bus supports is an aluminum box with fused Anderson Power Pole connections. RigRunners are available in multiple sizes, and more information can be found here:

To meter the total consumption and power characteristics of the load, I selected a West Mountain Radio PWRCheck meter. This meter actually shows a little less information than a standard Watt’s Up meter, but was selected due to the backlight on the display, its ability to log data to a computer, and its ability to have its firmware upgraded via a download from the internet. More information about the West Mountain Radio PWRCheck can be found here:

I selected a Maximum Power Point Tracking (MPPT) solar battery charge controller to squeeze every last watt out of my setup. MPPT charge controllers are usually significantly more expensive than standard charge controllers, but the expense is worth it. To learn more about MPPT charge controllers and how they work, visit: http://www.windsun.com/ChargeControls/MPPT.htm

After much research, I selected the Morningstar SunSaver 15A MPPT tracker. This unit was selected because it is relatively small compared to a lot of other devices out there and the manufacturer has really applied a lot of good engineering to their devices. This unit also allows for the installation of a remote panel meter which allows you to get power data about incoming and charging power, temperature, and if you use this controller to manage the load, load power data. This charge controller also has an RS232 interface available allowing you to record and analyze data using a computer. I purchased these items from Northern AZ Wind and Solar:

I am using two 20Ah AGM batteries sourced from a local BatteriesPlus, connected in parallel (my entire system is 12v, not 24, though it could be).

I also utilize Watt’s Up inline power meters, purchased from Ham Radio Outlet. These are indispensable meters that allow me to measure all aspects of power performance at many points within my box.
