* [[electrical:solar:charge_controller#mppt|MPPT]] - more complex, 2-3x more expensive, can run the panels at max power, optional with 12v panels and mandatory when nominal panel voltage is higher than nominal battery voltage. | * [[electrical:solar:charge_controller#mppt|MPPT]] - more complex, 2-3x more expensive, can run the panels at max power, optional with 12v panels and mandatory when nominal panel voltage is higher than nominal battery voltage.((e.g., 24v (72 cell) panels with a 12v bank)) |

PWM are cheap enough that it is common to start with PWM and upgrade to MPPT later only if necessary. After one upgrades from the PWM unit it can be kept as a spare/emergency part. | PWM are cheap enough that it is common to start with PWM and upgrade to MPPT later only if necessary.
