Review on Xijia 3000W Pure Sine Wave Inverter: Efficient Solar Power Converter for Home & Car (DC48V) by Elvis Kohl

Purchased 2000/4000W 48VDC -> 120VAC Inverter. I connected this inverter to a 48V 100Ah AGM battery. I checked it with an oscilloscope with and without load and showed a very good sine wave. Not graded like cheap inverters. The device stays very cold and the fans only turn on when the load reaches 1000W. Even with the fans running, it's pretty quiet. I tested the 1800w heater and it ran between load and no load at a constant 122VAC. Previous comments have raised concerns about grounding. I checked and the ground on the connector is indeed grounded to the chassis. Actually, there is no difference between AC plug and screw terminals. Another problem is the fuses. Internal 15Amp (6x) fuses are used but supplied as optional 20Amp (6x) fuses. Which fuses are correct? The unit also includes a wired remote control but has not been connected or tested. In general, I am very satisfied with the purchase and the operation of the device. GOOD: - Continuous voltage tested up to 1800W - Clean signal output - Exceptionally low power consumption when idling (approx. 15W tested) - Tested with approx. 88% efficiency - Good battery cables 4 AWG instead of 7 AWG in the description - As AC voltage display and DC current. installed instead of 1-Fuse Confusion? - AC plug is very tight with screw terminal, a problem with large plugs on some power strips.
