Review on WZRELB 1500w Power Inverter: Reliable Pure Sine Wave 12v to 120v DC AC Converter by Jake Pavelko

I got my new inverter and plugged it in only it beeps and isn't delivering power. I checked the fuses and they are ok. turned it over, looked at the label and the low level, and lo and behold they sent me 24 volts instead of the 12 volts I ordered. I connected 2 car batteries to check it, now it works fine. I decide to send it back or buy another deep cell and wiring to make my system work with this one. Moral of the story: Before you waste time checking fuses when they don't work, check the input voltage.
