Sometimes I just don't pay enough attention. When my backup Powerjack blew up, I bought the best deal on ebay for a low freq 48v/15kw split phase inverter. Thought I was getting a Powerjack. When it got here it says U-Power on the case. Whatever it is, It's the newest version for 2019 with Output Voltage Adjustment right on the front face! That's worth a lot right there.
Inside it appears to be powerjack. Sort of. The control board is definitely pj. The control board is larger than the mainboard. Its a 110v control board. Would have preferred the 220v control, but it shouldn't really matter.
It has one large transformer. About 7.5 inches across. Doubt its big enough to rate a 15kw rating. The transformer mounting is off center.
The mainboard is the kicker. Its very small! It only has 4 caps. The heat sinks are solid instead of finned. The bigger, older models had 3 large gauge wires from positive batt to heatsink. This baby has 2. Older version has 6 negative wires. 4 for this model.
It is nicely dressed up inside, unlike previous models I've opened. Wires are all neatly dressed and tied up. No ugly taped wire splices. I usually make some changes before I even run a new pj, but this one is so pretty inside I hate to disturb the landscape. At least wanted to take some pics first because I'll never dress it back up like it is now.
So powered it up. No issues with a light load. Adjusted it to 120v. Probably won't load it up heavy until I make my changes and connect up external fan controls. Hard to imagine that this baby powerjack clone could take the same loads my older version does. Guess we'll find out soon....
