Stopped working in a month
No proper voltage and neutral flow via gen option. Due to which lot of appliances are not working though the gen line can take the loadUpdating.After contacting service center it was replaced in a week.

Loved the product
The quality is solid solved my problem I installed it my self so yeah it’s the best there isEdit after putting to use for 6 months or soWorks like a charm no issues what’s so ever.As I use it to switch between an online and offline inverter for my lab. The change is quick not disturbing the work flow. However when not in use I turn off the input from the online inverter.
