NIMTEK NR5000 Pure Sine Wave Off-grid Inverter with Remote Control, Solar Inverter 5000 Watt 24 Volt DC To 110 Volt AC (24VDC)

bought and paid for expedited shipping 4-6 days air freight FEDEX paid for on the 18th didn't receive till the 27th 9 days later. Unit had a quality control sticker and a date with signature of September 9, 2016 not very good QC since item came with no ground terminal installed. Advertisement said unit also had a remote capability but there was no where to connect a remote switch. And to think it almost cost me close to a thousand dollars.NOTICE THE HOLE IN THE CASE BENEATH THE THREE NEGATIVE WIRE CONNECTIONS THIS IS WHERE A CONNECTION TERMINAL SHOULD BE.Contacted by seller who stated that a ground connection is not necessary due to case being bonded internally. That my be okay if you mount inverter inside a vehicle using metal screws and screwing to chassis of vehicle. But in a home use application where unit is screwed to a wooden wall their would be no grounding of device which is a violation of the National Electric Code and is unsafe to persons and property.
