I am about to buy a 16 split Trina panel system with a Solax-box inverter / 10kw storage. It will for normal house loads and an electric car.
Any thoughts?

Sounds good. Have you found an installer that you are happy with?

Hi Erwin,
The 16 Trina panels would equate to around 5kW of solar which seems very small and undersized for 10kWh of battery storage and charging an electric car.
Do you know what is your average daily consumption? (This is on your electricity bill, measured in kWh per day). Where are you located? Do you have any shading issues and is your roof north facing? These are all important questions which need to be considered.
Also how much are they quoting? I recommend you look for a reputable local company a get a least 3 quotes
Hope this helps,
Jason

Thanks all for your replies. I have gone with Mercury.
Yes Jason, I agree pv is too small for 10kwh storage, I have room to add more pv later. The roof us unshaded with north east & north west aspects. NIWA shows, 8kw pv at noon in summer or about 25kwh a day. We expect that it will take more than a day to topup the EV.
