Description
High Voltage Solar Charger
The GRAND series solar charger is an industrial grade MPPT solar charging controller with wide PV voltage input, adjustable charging voltage, RS485/LAN communication, modular design and high conversion efficiency.
The GS120L60 MPPT solar controller is an advanced Maximum Power Point Tracking (MPPT) battery charger for standalone photovoltaic (PV) systems up to 20kW. The controller provides high peak efficiency of 99% and consumes significantly less power compared with competing MPPT controllers.
The solar charger controller works at 120 vdc, it accepts wide PV input rang up to 430V.
It has input overcurrent protection , 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 can also be remote monitored via Wi-Fi or GPRS.
This solar charger package include any Wi-Fi modules.
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.
