I have a mostly unused WZRELB 7000 watt 24vDC inverter split phase 120/240vAC. It was bought last year and used for a short time. Everything works and I have the orginal box for it. There is one slight issue where the display screen briefly turns off and comes back on but this does not effect operation of inverter. Texts are accepted and more likely to get a hold of me because my phone is not always with me or turned on. Normally this inverter goes for well over $1200 so my price is about 1/2 of new.
