Let customers speak for us
from 157 reviewsService was fast and efficient. Battery arrived within two days of placing the order.
Thus was just an oder to replace the battery in my inverter, but I was impressed enough that I would use them again when the need arises.
Best service ever, fast delivery. Technically supportive, am extremely happy with the service and the product.
I write reviews on every product I buy. The GenXair 24000btu is more than what they could described.
It's an excellent unit delivering above expectations.
How long it will last and the aftersales service we will see in time.
First impressions is above average.
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
