Discussion Overview
The discussion revolves around the feasibility of using a 24-volt permanent magnet generator (PMG) to charge a 12-volt battery bank, particularly in the context of limited wind conditions and the specifications of the charge controller. Participants explore technical aspects, potential challenges, and the economic viability of wind energy generation in low-wind environments.
Discussion Character
- Technical explanation
- Debate/contested
- Exploratory
Main Points Raised
- One participant inquires whether a 24-volt PMG can effectively charge a 12-volt battery bank given their charge controller can handle high voltage and dump at 14.5 volts.
- Another participant questions the operational voltage range of the charge controller and whether it frequently drops out due to low voltage from the 12-volt PMG.
- Concerns are raised about the power output of wind generators, noting that they typically require wind speeds of 15 knots or more to generate significant power.
- A participant mentions that their average wind speed is below 12 mph, with only occasional higher gusts, leading to low voltage output from the turbine.
- One participant expresses skepticism about the investment in wind energy given the low wind conditions, suggesting it may not be cost-effective.
- Another participant points out a lack of technical data on the charge controller, suggesting it may only charge a 12-volt battery within a narrow input voltage range, which could complicate the use of a 24-volt generator.
- There is a suggestion that a more advanced charge controller with a DC-DC converter might be necessary to accommodate a wider range of input voltages.
Areas of Agreement / Disagreement
Participants express differing views on the viability of using a 24-volt PMG for charging a 12-volt battery bank, with some expressing skepticism about the effectiveness of wind energy generation in low-wind conditions. The discussion remains unresolved regarding the optimal setup and the economic feasibility of the proposed system.
Contextual Notes
Participants highlight limitations related to the charge controller's voltage range and the wind conditions affecting power generation. There are unresolved questions about the specific performance characteristics of the charge controller and the PMG under varying wind speeds.
