307V 100A mppt charge controller for lifepo4 battery
MPPT Solar Charge Controller Description
The solar controller adopts multiphase synchronous rectification technology and common negative pole design, it chooses high speed processor and advanced MPPT algorithm to make it has high response speed, high reliability and other standards.
The advanced MPPT algorithm that the solar controller adopts can trace the maximum power point of PV arrays quickly in any situation to obtain the max. power from PV arrays. And the multiphase synchronous rectification technology can achieve high conversion efficiency in any charging environment and improve the utilization rate of solar power system greatly. According to the rated voltage of battery bank system, our factory can provide the MPPT solar charge controller from 192V to 540V which suitable to almost off grid solar power system
