-"MPPT required for series" is shorthand for "when [[electrical:12v:electrical_notation|Vmp]] greatly exceeds battery bank voltages then PWM is hamstrung and MPPT peak power advantage is undisputed."
+"MPPT is required for series" is shorthand for "when [[electrical:12v:electrical_notation|Vmp]] greatly exceeds battery bank voltages PWM output is hamstrung and MPPT advantage is overwhelming."((In our PWM backup scenario we are not concerned with //maximum// power, only getting //some// power from the panels until we can replace the dead MPPT.))
 The flipside to this is "when Vmp is close to battery voltage then MPPT advantage is thinnest and PWM may actually make more power." For more on this edge scenario, see [[electrical:solar:output#panel_temperature|temperature derating]].
