   * MPPT controller is 95% efficient
   * PWM yields, overall, 85% of MPPT yield.  PWM yields will be quite close to MPPT yields when other forms of charging is present, as PWM will no longer be [[electrical:solar:pwm_tweaking|hamstrung by low Vbatt]].
-  * isolator charging is done in early morning, and discontinued when alternator no longer raises voltage.  At this point ~70% of charging will be done.
+  * isolator charging is done in early morning, and discontinued when alternator no longer raises voltage.  The chart assumes at that point [[opinion:frater_secessus:charging_faster|~70% of charging will be done]].
-  * DC-DC (or generator) charging is is done in early morning, and discontinued when Vabs is achieved.  At this point 85% of charging will be done.
+  * DC-DC (or generator) charging is is done in early morning, and discontinued when Vabs is achieved.  We assume at this point 85% of charging will be done.((adjust as necessary for your charging current))
   * wattage listed as ''any'' means "any amount over 100w".
   * solar-only charging the same number of amps into lithium would require about 15% less panel than lead.  Lithium can be charged successfully off alternator/generator only so no panel would be required.
