Regen Wind turbine on an 8kw Sunsynk inverter

We have finally finished testing an install of our Regen 3KW-HV Wind Turbine on an 8KW Sunsynk Inverter.

Power goes directly from the turbine via a controller to the inverter, which in turn sends the power to the load and to charge batteries as needed.

This installation site has been hammered by the 2024 April Western Cape storms and came out with flying colours. This model has variable pitch blades that stop over-spinning in strong conditions by adjusting blade pitch to slow down.

Running almost silently, it runs day and night providing power when the sun cannot.

Traditional domestic turbines were developed for charging directly to lead acid or AGM batteries, with some small tweaks to the controllers they could be set to charge Lithium batteries too, but when the batteries are full the turbine stops.

Sunsynk has innovated wind turbine integration on their inverters, eliminating the need to send wind power only to the battery bank, so all the power generated by the turbine can be used by the inverter.

We have a few models to choose from and this will largely depend on the size of your inverter and what it can take.  you are limited on the inverter by the voltage range that the MPPT can accept:

here are some examples: (Note:  it is your responsibility to double-check the specifications of both the inverter and turbines before installation).

• Sunsynk 5KW – MTTP range is 125V to 425V so you want to look at using one of our 220V turbines
  Sunsynk specifically warned against going over 350V with this unit.  Note the startup voltage on the MPPT is 125V in total so if you have solar on one string and it’s producing power your start feed from the turbine is lower which helps, we recommend the 240V turbines for this unit.

• Sunsynk 8KW – MTTP range is 125V to 500V so you want to look at using one of our 220V or the 350V turbines.
  the datasheet shows 425V in total for the inverter.  Also, note the startup voltage on the MPPT is 125V in total so if you have solar on one string and it’s producing power your start feed from the turbine is lower which helps, we recommend the 240V and the variable pitch 350V turbines for this unit. see the Datasheet here
• Sunsynk 12KW – MTTP range is 160V to 800V so you want to look at using one of our 220V 350V and 380V turbines,
  The MPPT on this unit can take higher voltages so you would be safe using the 3 and 5 KW turbines in 220; 240; 350 or 380V ranges.
  See the Datasheet here
• Sunsynk 16KW – MTTP range is 125V to 500V so you want to look at using one of our 220V 350V and 380V turbines.
  You should in theory be able to fit three 5KW turbines on this unit as it has three MPPT controllers. See the Datasheet here
