report on solar and Magnum inverter and load support

Hi All,

I'm plugged into 15 amp shore power. I've "dialed in" a maximum draw of 15 amps on the Magnum. After shore power initialized (there are built in transfer switches with a time delay), I turned on the inverter.

Then I deliberately over loaded by about 2 amps. Load support provided the extra power seamlessly. Then I over loaded by about 12 amps. Again load support "did its thing".

On the solar side, when the Magnum is in float mode it plays well with the Blue Sky. However when the Magnum goes to absorb mode (it did after the 2nd deliberate over load) it does NOT. I found a work around by deliberately triggering an equalization on the Blue Sky.

I have 15 amp power for the next 48 hours--a good thing as it is going to dip to -1 C Thursday night. I am connected via 50 feet of #10 cord. I may run a second shore power cable to get a little more heat going. Forecast high is 9 C and it is currently 7.5 C.

Magnum is in absorb at 4 amps 14.9 volts, Blue Sky is at 4.5 amps 15.1 volts.

    We just returned to the warm side (over the lowest continental divide in North America) from the Rocky Mountain front (east side of the divide) where your Canadian cold weather hit yesterday with 20F and blowing snow they expect 6" of the stuff on the ground - PLEASE keep that cold white stuff up your way for a few more months.

    West Glacier area now at 40F raining and windy
  • It is 94F here right at the moment. Fans going, windows open all night, a thin sheet is more than enough. Seenyore pianotuna are you planning on bailing out of this perfect area for dome homes made from block ice when you retire?

    My Montana great uncle used to quip "There used to be a barbed wire fence between here and the north pole but a blizzard took it out years ago"
