Which 8nverter, Huawei sun200-3ktl or 4 ktl.

[Tony54]

I'm going to have 8 panels ja solar 460 watts installed on my roof and can have the 3 kw or 4 kw Huawei inverter for the same price.
The total pc input could be 8 X 460 =3680 watts. I know inverters will handle more pv than their rated kilowatts but which would you advise me getting?
I don't intend increasing my pv input and would like a quiet inverter but not a dealer breaker.
Thanks for reading

Hi Tony! I don't know if you still need answer on this but here it goes. If you don't plan in increasing the number of solar panels, than a 4kW inverter should be your choice. The panels that are summing up 3.7 kWp might produce more than 3kWh if you have a bigger than 3kW inverter. So go for the 4kW. Here you can find the detail specs: https://re-energy.ro/product/invertor-sun2000-4-6ktl-l1-4-6kw-monofazat-hibrid/
If you plan to have 2 strings, make sure that the start-up voltage condition is met (100V) --> therefore you will need at least 3 panels per string.
