[[electrical:solar:charge_controller#pwm|PWM]] controllers are especially hamstrung in this scenario; since they run the panels at battery voltage (Vbatt) they produce the least power exactly when the most power is required. By the time Valt is reached PWM controllers are able to produce meaningful power. | [[electrical:solar:charge_controller#pwm|PWM]] controllers are especially hamstrung in this scenario; since they run the panels at battery voltage (Vbatt) they produce the least power exactly when the most power is required.

| ===== when augmented charging works best ===== |
| |
| Boosting solar charging with alternator, genny, etc, works best during bulk stage. This is true for alternators because their terminal voltage is rather low, and for both generators and alternators because Absorption stage takes little current and a great deal of time. |
| |
| In practice, it is generally ideal to start the charging from 50% [[electrical:depth_of_discharge|depth of discharge]] on alternator or generator and discontinue alt/gen charging when Absorption voltage is attained.((assuming no significant loads are running)) |
