VertaMax 1500 Watt 12V Battery Power Inverter DC to AC Car, RV, Solar, RV, Windy Nation's VertaMax 1500 Watt DC to 120 AC Modified Sine Wave Power Inverter provides household power for RV's, cars, boats and wind & solar off-grid systems! The VertaMax 1500 converts 12 volt battery power to 120 AC power so you can power up household appliances when the electrical grid is not accessible. The VertaMax 1500 is capable of powering any device or multiple devices that do not exceed 1500 Watts in total power draw. Typical examples of appliances that can be powered by this inverter are: computers, televisions, video game players, cellular phone charger, a 1000 Watt microwave and the list goes on The VertaMax 1500 provides reliable AC power whenever and where ever you need it! This is a modified sine wave inverter. It should run everything. But anything with a motor or compressor will use more power and not be as efficient. I have not taken one apart. But by what they have you should be able to pull 1500 watts max thru one outlet or 750 max thru 2 outlets. http://forums.windynation.com/community/threads/flying-as-of-6-30-2010.197/page-14 The one I bought is a different brand it is under post your photos. It had (2) 14 ga wires for 2 outlets. Kept going to alert and shutting down. I changed both to 10ga wires and it has worked ever since.
Mine is the pure sine wave w/ 3 outlets as pictured here: https://www.amazon.com/VertaMax-3000W-Surge-Inverter-Off-Grid/dp/B06XPR4X9C
The max output is a combination of all outlets. 1 outlet should supply the max as long as other outlets are not in use. If your pulling the max you may experiance issues Tom stated. Max out puts are not intended to be run for long periods of time.
OK, so the outlets are not limited, but power draw will be cumulative. At this point the maximum draw we've ever attempted is a 900-watt blender, which operates for brief periods (usually under one minute). We try to limit its use to periods of full sun and a fully charged battery bank, but I guess the fact that this has never tripped any fuses or breakers makes more sense now. Thanks!
