With the information provided it sounds like it needs to go. We are full time so our mileage is different, obviously. Charging laptops, drill, wife's nutri-bullit thing are about the only 120 uses we have.
Not "may work"..."does work". The inverters in APC computer UPS units are MSW. "Electronics" mostly don't care. They generally run off power supplies, which almost never have any issues with MSW.Really want PSW for electronics, may work but wasting lots of energy.
And even the good 12v stuff fails. But rarely do the 120v power bricks fail.But again, DC-DC conversion is best, not at all rocket science, of course lots of rubbish out there, especially in the cheap Chinese arena.
A non-issue actually.Yes, off grid power inputs usually surplus to your needs gives plenty of headroom, makes such inefficiencies a minor issue.
I guess I'm just unprincipled then.Others need to cut consumption when inputs aren't enough, need to be more conservative and maximize efficiency.
And then some strive for the latter out of principal.
Exactly, and that touches upon the heart of the matter. I generally try to address the question that was asked, and/or try to work with what is already in place.Different strokes. . .
”Modified”for sure. Lots of small UPS units dont even output an alternating polarity.The inverters in APC computer UPS units are MSW.
