From this it can be seen that PV modules output power increased with the increase of battery voltage and the average power to battery is 210W power point 2 in fact the controller s conversion efficiency won t be 100 so the actual average power to battery will less than 210w The other more than 90W power couldn t be extracted caused a waste of energy This MPPT solar controller works near the maximum power point Through Page 13 collecting the date of pv output voltage and current the maximum power point is determined That makes PV modules worked at voltage 34V 38V this voltage change is dynamic change the corresponding current is 8 34 A 7 5 A 34V 35V 36V 37V 38V Also PV modules output power is 285W 300W the average power is 292 5 W the unextracted average power 7 5W is dynamic loss If the controller s conversion efficiency is 92 battery can get 268 6W power actually At this time if battery voltage is 21 V the charging current will be 12 8A if battery voltage is 28 8V the charging current is 9 33A This two currents are both larger than PV output current so the Energy utilization rate of MPPT way improves more than 27 9 than ordinary way The above contents are examples for understanding MPPT solar charging and may have a little difference form practical application There isa relationship between the ascension of energy s utilization rate and the difference between solar panels Vmpp and batter
