  • Post in thread: Shipping container design

    It's a metal container in the middle of a field in central California. During the summer, there's no way the anything short of running an air conditioner all day is going to make it habitable for someone. It'll be insulated which will help a little bit, as well as sitting under the shade of...
  • Post in thread: MPP PIP-1012lv-ms bypass problem

    For some reason, when we have power connected to the AC input and the screen shows bypass, the AC output still runs from the inverter. Setting 01 is set to Util, so utility power should power the load first. We've tested the setup 3 separate times in the last two days and it has worked...
  • Post in thread: MPP PIP-1012lv-ms bypass problem

    Ok, with some additional testing, it appears that the inverter is always running on the MPP Solar units even if running in bypass mode. When set to utility priority, the inverter is powered by the AC input. This imposes a limit on the available output power even if in bypass mode. It doesn't...

    The location it is in gets regular sustained winds of 20-30mph with gusts much higher occasionally. I'm pretty sure Aluminet wouldn't last very long being battered by the winds. A swamp cooler would probably make it cool enough not to die inside, but it still wouldn't be comfortable enough...

    Well if the AC uses about 1kw and the solar produces 3kw peak(I know they will produce more like 2-2.5kw peak and only for a small part of the day) then that leaves 2kw(1-1.5kw) for other items inside. All of the other devices total will probably draw 400-500w. Plenty of overhead I think. We...

    I am planning an installation in a shipping container used as a small office. The unit is going to be completely off-grid, with a 2kw generator as a backup. What I need the system to do: Power an 8000 BTU A/C during the day in the sun (1000W roughly) Power a small microwave occasionally...

    Tracy, out near 580. I don't think there will be enough surface area to tip the container. The bigger problem may actually be people messing with the panels at night. We might do a skirt around the top to make it look less like there is something up there. They are planning on installing...
