I received the shipment in violation of my order My order was 4,000 to 7,000 watts And it received from 2000 to 4000 watts Also contrary to specifications Photos of the shipment received are attached
ok, 48V to 220V 1kw tested
I asked for the first inverter, and the second one came, and I didn't make any sense of it. I asked for 7,000
I just got it, apparently it's a good inverter. I'm still going to run tests.
I measured inverter with a oscilloscope, it has true sine wave AC power. It can handle loads at least 3000 watts as measured, i didn't had larger load to confirm 8000w peak/4000w continous capability. Idle consumption about 15-25 watts. Overall, it is a good inverter for a reasonable price.
OK, it's already working
So this converter is already the middle class of these devices. It makes regular weak noises during operation, it is also a habit. Performance wise, no problem, so far it has tightened everything I needed. Even the run-in of demanding equipment without hesitation. Apparently it has decent capacitors. The weak point is the display, you can't see much of it. Silent operation. The USB output doesn't work, I don't mind. The curve will be really decent, even asynchronous motors run well. I recommend it.
its got something rattling around inside it,arnt pulling apart as my loose wantarray
excellent !
Delivered okay. Not tested yet.
