Really pleased with this inverter! i have it connected to three 590 watt panels and it is pumping out the power. i currently use it without a battery and have used a.i. to fine tune the settings ( highly recommended). i cannot speak to long-term durability as i have only used the unit a week.but so far , i'm really pleased as compared to much higher price similar units.
