- | MPPT [[electrical: | ||
- | |||
- | - Imagine a 24v battery bank being PWM charged by two 12v panels in series, for example. The series configuration is not important, but the relationship between panel voltage and charging voltage is. | ||
- | - Imagine a the 24v panel string above MPPT charging a 12v battery bank. The MPPT controller dies and a backup | ||

- | "MPPT is required for series" | ||
- | | ||
- | The flipside to this is "when Vmp is close to battery voltage then MPPT advantage is thinnest and PWM may actually make more power." |
