Service 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.

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
