In this video, we charge the Power Queen 12.8v LiFePO4 batteries powering the off-grid ham shack using a vertical axis wind generator. Also covered are the various methods of charging our solar battery storage, when there is no solar power.

Charging LiFePO4 with a wind generator

On Monday 22 January 2024, we had a sudden rise in temperatures at KP25QC. With the higher temps came gusts of wind averaging 10m/s – 22mph. Not really a massive wind storm, but strong enough to test how effective the wind generator is when connected to a Genasun GV Boost charge controller for 4S LiFePO4 batteries.

This post just ties everything together. The Wind Generator, the Genasun charge controller, the Power Queen batteries, and our ability or inability to charge our solar storage with the wind.

Take battery storage seriously

The most important aspect of the off-grid ham shack is its battery storage. The more watt-hours of battery storage one has, the longer one can “wait-out” the grid being down.

Food for thought

When a storm hits and the grid goes down, getting power back becomes a high priority. High winds, lightning, ice, or heavy snow can all contribute to power loss. The loss of grid electricity nay become more than the annoyance of not being able to turn on a light, radio or television. Often, the loss of grid power has serious repercussions affecting heating, refrigeration, hot water, storage of medicines, and the ability to charge critical communication gear.
As we begin understanding the causes of power loss, we must make efforts to understand what steps to take to keep our secondary power systems running. Both are necessary when preparing for potential outages, and responding effectively when they occur.
