This is a B17 Inverter/Charger module on the scales. Under 10.5 Lbs. Last year Midnite tested a single module in an enclosure designed for just 1 module. Future model maybe? 6 small fans fed about 8 VDC, so slow and very quiet. Loaded up 4kW for 3-4 hours if I recall. Not a single internal temp being monitored ever reached a level that was of any concern.
A similar test was done using the B17-5 main frame. 1 module. A 5kW load applied. 2 hours later no smoke, no abnormal temps recorded. I wanted to keep going higher.....problem. The DC input has a 100 amp surface mount fuse. At 5kW it was pulling 98 amps at 50 VDC. Hmmm..
Hey boB! Can I double up the fuses? Sure! 6Kw load applied....After 15 minutes the temps were climbing too fast for comfort and test ended. An hour later 7kW load tried. Temps started climbing fast after 3-4 minutes. We found the wall! Stop! Wait 30 minutes....8kW? No! 9kW? No!
Let's jump right to 10kW! For the record, that's input. 200 amps at 50VDC. I stopped the test at about 20 seconds....Why? Because the magic smoke was still contained! Do it again? OK. But added another 500 watts to the loadbank...less than 2 seconds later...the anti-suicide protection kicked in and the module disabled/shutdown. No harm done! A single module loaded to 3kW can then easily surge to 10kW! Midnite has done that a few hundred times and not one module has ever failed under load.
Based on Midnites testing and my own, a good estimate on B17 ratings would be 3.5-4kW cont if 1-2 modules installed. 3+ modules space begins to get crowded and added heat so 3-3.5kW ea....? Keep in mind the B17 is overdesigned, just like the Rosie, and they will underrate it. They want the odds of you dealing with the hassle of returning a big heavy 10.5Lb module to be very low!
The Rosie is badazz...she is out there in the wild and earning a well deserved reputation as a rock solid performer. The B17 is Rosie on steroids and the ultimate AIO. Hardware is mostly done and proven. Once boB can get back to the goofy ones & zeros it needs to shine, firmware, then we should start hearing more about it.
The B17 VS Air Compressor? That was me having fun on a hot Summer day.
