It's true what you say but don't forget 95% is China made, after all makes it very difficult to make the good choice.
The hybrid inverter I look to is the Goodwe GW5048D-ES, not cheap, 69,000 thb at technosolars.com and yes, also made in China.
You also have to realise the big price differents between High and low frequency inverters. The low frequency inverters working with transformers (heavy) in contrast to mosfets (highfrequency).
But this is not always stated.
In my opinion I prefer the one with transformers, and to be honestly, I don't know the Goodwe is high or low but considering it must be a low frequency one, the device weighs 30 kilo, so heavy.
Also about the batterys, I still can't make a decission, my mind goes out from Lipo4 48V 240Ah, and I considering assembled or do by myself.
What are your experiences in this?
