Let customers speak for us
A must have for every DBboard
Great innovation
Still waiting for the power to trip. I know its a weird ask, but would like to test the system and see what it has to offer.
Still figuring out how the battery usage is managed, but as for the rest it operates seamless.
Got the app operational with a little help from my friend and gives useful information. Enjoying the Deye 12kW journey.
Still need to neaten-up the wiring though.
I thank you.
Overall, this inverter has exceeded my expectations. Highly recommended to anyone

"I'm loving my GenXair Inverter AC! 😊 The energy efficiency is on point, and it's kept my space comfy all summer. The smart climate control is super handy – love being able to adjust temps remotely. It's quiet too, so no annoying background noise. Would definitely recommend for anyone looking to upgrade their cooling game!"
Very professional and I will certainly be purchasing again
