The GS series solar charger is an industrial grade MPPTsolar 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.
1. Efficient MPPT controller algorithm, MPPT efficiency is not less than 99.5%, and the conversion efficiency of the whole machine is up to 98%.
2. Charging mode: third-order charging (constant current, constant voltage, floating charge) can effectively extend the life of the battery.
3. LOAD mode has normally open / normally off mode, light control mode, dual time control mode, light control – fixed time control mode.
4. Customers can choose to charge 3 types of commonly used batteries (sealed lead-acid batteries, colloidal lead-acid batteries, open lead-acid batteries), and can customize the parameters to charge other types of batteries.
5. With current limiting charging function, when the user’s battery board power is too large, the controller automatically maintains the charging power, and the charging current will not exceed the rated value.
6. Support multiple machines in parallel to achieve system power upgrade.
7. With high-definition LCD display function, you can view the running data and working status of the device, and support the setting of related parameters.
8. RS485 communication, can provide communication protocol, convenient for customers to integrate management and secondary development.
9. Support PC software monitoring, support WIFI module expansion to achieve app cloud monitoring.
