ok so here are the specs. once again renogy customer service was quick and efficient. so there is two specs one for max power (4000watts) and one for overload protection. so it will handle the max power (4000watts) for 5 seconds and if it hits a overload conditions that will trip the inverter to protect it with in 40milli seconds.
You didn't state the model number. I would assume that's for the Renogy
low-frequency 2000 watt inverter which costs about $600 and weighs about 50 lbs., right? That toroidal coil, which helps provide all the inrush current, makes for a heavy unit. Specs for most of these 2000 watt low-frequency inverters are somewhat similar in terms of their power/duration specs.
The
high-frequency Renogy 2000 watt inverter, which costs about $300 and weighs 12 lbs. only has a 4000 watt peak rating as far as I can tell. My guess, the peak rating means it will only output 4000 watts for 20-40 milliseconds. Not enough time to produce much inrush current. I believe this is the unit the OP was looking at purchasing.
The Xantrex 2000 watt Freedom X inverter, which I believe is also a high-frequency unit (at 15 lbs.), will output 4000 watts >2 sec. Xantrex states specifically it's very effective for starting motors. That's an awesome spec for a high-frequency inverter.
