I post this stuff because I've been searching discussion groups for information and finding mainly scattered snippets directed at the questioner that don't help explain the big picture I'm looking for.
I shoulda realized ...
-- Snag-----------------------------For example the Jackery 290 claims to have an MPPT controller but monitoring the charging current and voltage doesn't show signs of one, it looks more like a current-limited step-down converter that doesn't hunt for the maximum power point. I don't want to experiment with it until I have a good idea of what it can or can't accept for input. Their phone support site naturally isn't staffed with engineers and I haven't found evidence of user experimentation beyond measuring run times. One snippet was a mention in the FAQ of 200W solar panels being acceptable, without explanation of what it would do with their excess power. Apparently it limits itself to pulling 60W.I'm measuring my 12VDC freezer's run time on it. So far it's headed for 15 hours, more than enough to sleep through.
