When I say it stops charging, the controller switches to a state called “unload “. This is the same as “brake” mode. Maybe I can make a video tomorrow showing the voltages.

When 14.4v is reached, the controller stops charging, even though the battery is not charged. This happens very quickly when I drive the generator with my battery drill. Same would happen on a windy day.

Thanks everyone for your feedback. I am an electrician so understand your comments regarding the various stages of charging and internal resistance of batteries increasing as they become more charged etc. What I don’t understand (and this is my issue), is why the controller stops charging at 14.4 v ( this is a pre set parameter for lead acid) even though the battery is not charged. check out the attachment. thanks again everyone ⛵️ Information-Bulletin-2022-1-Charging-Cycle-explained.pdf

Hi, The controller is the latest 12v Hybrid from Silent Wind. I have been measuring the output voltage with my multi meter to confirm the produced voltage. I’m going back to SW tomorrow asking them to confirm my suspicions that the controller isn’t limiting the produced voltage, as it keeps rising as the generator speeds up until it reaches 14.4v (cutoff voltage). This would be fine if the battery was charged, but I am using a battery that is far from fully charged.

I too am a bit unsure. This is the App which receives the data from the controller, The “Battery “ Is measuring the voltage of the battery. “wind “ must be the generator output. I can’t find much information about it all

Hi Jon, I did some more testing today and got the battery voltage as high as 17 volts. That certainly isn’t going to do my battery any good. My conclusion from that is that the regulator ain’t regulating. Bugger! I recently imported it directly from the Silent Wind manufacturer in Portugal.

Thanks, Strange, as they are not attached, but included in the text. I have attached as JPEG's. Hope this works. Cheers, Dave

Hi, Does anyone have any experience with Silent Wind generators that can help answer these questions? 1) is it normal that 6 volts shows here? I can see the battery voltage being charged by the generator (13.1v). I was driving the generator by my battery drill at home in my workshop The "unload" keeps coming on. Why would this be? What exactly does "unload" mean? The battery voltage is only 12.4v, so wouldn't think the generator should stop charging.
