The price was right and for a 12v system this inverter gives clean power but not up to 1500w. I still give it a rating 5 stars for the price, fast shipping and features, but it's more like a 1000w inverter. I tried running a 1250 pulse load at 850w but the inverter said no. 12 volt systems are for small things, I'll switch to 48 volts and buy another one of those inverters rated at 48 volts. I'm sure it will meet my requirements.
