Advice needed on adding a Wind Turbine (generator) to a DIY PV Solar System. Answered
I have bought a 12 volt FD-300 300 watt wind turbine to add to my 12 volt DIY solar setup. The solar setup consists of 3 home made 70 watt panels on a single axis tracker charging 6x 12 volt 85 ah batteries wired in parallel (510 ah total) through a 20 amp controller. I run a 12 volt fridge/freezer (120 liter) and my now 12 volt (was 240 volt) evaporative air cooler (cools our 3 bedroom house) off the controller load output. The wind turbine has an inbuilt regulator. The instructions for the wind turbine tell me to attach it's + and - wires directly to it's own dedicated terminals on the battery bank. This is of great concern to me. How can this be done when the batteries are already connected to each other and to my systems controller? If it can be done without damage to the batteries would I still run the appliances through the load output on my controller? Would the different charge limiters cause an issue? My controller cuts out at 13.7 volts while the turbines controller would want to allow a charge of 14.1 volts. The two controllers also have different lower limits. As you can see I'm confused and in desperate need of quality advice. Thank you for taking the time to read this.
