3rd generation MPPT Charge Controller 55A at selectable 48V/60V/72V/96V is with real MPPT(Max power point tracking, range 75-240V) technology by special Hall sensor circuit to track max solar power from solar panels, MPPT technology is necessary for any solar PV systems over 200Watts today! The controller actually detects the optimum operating voltage and amperage of the solar panel array and match that with the battery bank. The result is additional 15-35% more power out of your solar array versus a PWM solar controller. Although the MPPT solar charge controller is more expensive than its PWM counterpart, it is generally worth the investment for any solar electric system over 200 watts.
It is also built-in replaceable fuses, smart fan cooling to continue full power output all day without derating! Very robust even in Africa desert area! Wide solar panels input voltage 75-240V!

*Puncture Li battery protection PCBA: Normally MPPT or PWM solar charge controller will puncture MoSFETs of protection PCBA inside of Li-ion battery pack when cut off the charger from Li-ion battery under full charging, because the output of voltage will soar huge instantly! Our patented programming and tech could avoid the voltage soar!
In that stage, the controller will deliver 100% solar power to charge battery.
When the battery has been charged to absorption voltage point, constant-voltage regulation is used to maintain battery voltage at the absorption point, to prevent heating and excessive battery gassing. The battery is allowed to come to a full state of charging at the absorption voltage point.
After battery is fully charged in the absorption stage, the MPPT controller reduces the battery voltage to the Float voltage point. The float stage provides a very low rate of maintenance charging while reducing the heating and gassing of a fully charged battery. The purpose of floating is to protect the battery from long-term over-charge.
Equalize charging will start during period of 30 days. It will charge battery at a higher voltage to active the battery, usually 30mins, depending on different battery type. Equalize charging will prolong battery lifetime.
