Has anyone had any experience of adding a Wind Turbine complete with inverter to a home that already has a Solar PV installation?

Jakesdad · Oct 10, 2023

We have 16 405W Longi PV panels feeding a Sunsynk 5kW hybrid inverter, connected to 3 x 5.32 kWh Sun-Batteries. The installation is approximately 7 months old and we are very happy with its performance. I have been looking at adding a wind turbine and additional battery capacity and over the past six months or so have confirmed that we have sufficient wind speed. I am told by the installer of the Sunsynk system that although the Sunsynk inverter is capable of accepting a turbine input unfortunately, all the MPPT’s have been used on the inverter. They have suggested that a 8kW inverter could be fitted instead of the current 5kW unit providing an open an MPPT with 425 Volts capacity.

The turbine i am looking at is a 1kw Skywind NG, it comes with an AC inverter. I can add additional battery capacity to the Turbine inverter. My question is does anyone have experience with a dual installation (essencially separate systems feeding the same house) and if so, can it be done and what are the things I should look out for? The current Solar PV system is grid tied and has an export limitation set to 3.68kw.

My wind generator produced power at almost exactly $100/KWHR before I took it down so it wouldn’t fall on my solar array.

Small scale wind is really hard to make work as well as you think.

$2700 will buy you a lot of additional panels.

Wind doesn't seem viable for small installations. I get you're in Derbyshire so have much more wind than sun, but it's so expensive given the power you generate that it seems not worth it. I did buy a wind turbine to refurbish as a fun side project but didn't bother adding it to the incoming solar system as it's a lot of hassle and effort for occasionally 1kW, and a dozen more panels is cheaper and more effective. Only fi you don't have space for solar and are off-grid and have to have power in the winter months and gales is it possibly worthwhile. Or do it for fun.

I think if you did have it the cheapest way is to have it on its own charge controller and feed the battery directly. Didn't interfere with the inverter at all then. But I decided more solar was much cheaper and easier.

Keep the wind system separate to the solar system.

If you live in a suitable area, wind works well. If you don't live in a suitable area, wind doesn't work well. Adding wind and making it work for you is a whole new learning process.

A friend of mine had a 700w turbine on top of a 6m (19.6ft) pole and lived near the sea and got constant sea breeze nearly every day/night. He was dump loading nearly 24/7

My wind turbine stories are the opposite but at least my young son enjoyed watching it spin, when it did.

The turbine you propose is only 1.5m diameter, it's inverter in the pics s a Sun1000 gtil2 1000 from China. So its never going to produce much even in the Peaks and not going to last long. If you do have good wind and want to harvest it then get hold of an old Proven turbine, the Rolls Royce of small turbines.

Although as others have said its probably not worth while, however if you do go for it, if the Turbine comes with an "A/C inverter as you have stated" why do you need a replacement inverter with an additional DC MPPT input?
