The M48120 MPPT solar controller is an advanced Maximum Power Point Tracking (MPPT) battery charger for standalone photovoltaic (PV) systems up to 7kW. The controller provides high peak efficiency of 99% and consumes significantly less power compared with competing MPPT controllers.
The solar charger controller works at 12V, 24V, and 48vdc, it accepts wide PV input rang up to 250V.
It has two separate 60A MPPT trackers, they can also work in parallel to accept a max of 7KW input power from a single solar array at 120A, for more details, please refer to the wiring diagram.
It has input overcurrent protection for both 60A trackers, when the PV array produces more than what the controller is rated for, it will limit the input current.
Tt has various battery charging algorithms, intelligent discharge control, RS485 communication for convenient integrated management and secondary development. It also can be remote monitored via Wi-Fi or GPRS.
It can communicate with the built-in solar charger of Sigineer M Series inverters(M3024NC/M3048NC/M6048D/M12048D) to expand its solar charging capacity and synchronize the charging stage for lithium batteries.
This solar charger package doesn’t include any Wi-Fi or GPRS modules, which are sold separately.
The solar charger is designed with positive ground, only the positive terminal can be bonded to the ground.
In a negative ground system, the charger should be left either ungrounded or bonded to a separate ground cable.
Connecting its positive terminal to the negative ground cable will damage it permanently, and it is not covered under warranty.
The Wi-Fi module isn’t offered for free with the solar charger, it is sold separately.
