XYZ INVT4000 Watt Pure Sine Wave Inverter 36V DC to 110V 120V AC Car Power Invert Surge 8000W Power Converter for Solar System.(4000W 36V DC to 120V AC)

seems to work ok but the inverters voltage jumps around a lot like 120 then 80 then 110 but when under loads it settles

This is the second unit I bought, the first one was a year ago, 48 volts and works great. This one is 36 volts. If I have to find any room for improvement, it would be the output hardwire connection. It would be nice to have a slot with set screw rather than needing to crimp on spade connectors. Still 5 stars for quality and price.

Used this as the inverter for my diy solar generator. Have only used it a couple times but is able to power both of my refrigerators during power outages just fine. Have also used this as a remote power station for using power tools while far away from a power source for extended periods. Unit has shown adequate cooling even in 95+degree F weather.

I works for my needs. My only suggestion is that when you use large battery bank you have to watch the low voltage cut off. When reached it should not come back on until it reaches higher voltage. It will turn it's self on and off several times if you don't watch it.

Have been using this product for more than 4 month, the overall quality is pretty good, reliable, not heavy, can withhold high current surge, especially for this price. Have tried many similar products from Home Depot, Lowes, this one is the best for me.

Il ne donne aucunement les résultata qu'il ont décrit.Il n'est pas performant pour un 4000 watt.Un ondulateur de 1500 watt est beaucoup plus performant que ce 4000 watt nominal.J'ai un 2000 watt, il est beaucoup plus formant que ce 4000 watt.J'attends un réponse du fabricant.Si positif, je vais corriger mon évaluation.Pour le moment, je le conseil pas.
