the latest communication protocol and the voltage technology standard of
solar controllers. The products have many excellent functions:
■ Automatic identify and display the type, model and relevant parameter
data of controllers;
■ Real-time display the operational data and working status of the connection
devices in digital, graphic and textual forms by a large-screen multifunction
LCD;
■ Direct, convenient and rapid operation of six navigation function keys;
■ Both data and power owing on the same lead, no need for external power;
■ Real-time data monitoring and remote load switchover of the controllers,
and data browse and modication of device parameters, charge control
parameters and load control parameters;
■ Real-time display and acoustic alarm of failure information of the
connection devices;
■ Longer communication distance based on RS485.
2.2 Main functions
Functions like the real-time monitoring of the operational data and working
status of a controller, the browse and modification of charge/discharge
control parameters, the setting of device parameters and load control

browse page upward and downward.
5.5 Test Operation
Load switch test operation is conducted on the connection solar controller
to see if the load output is normal. The test operation does not affect the
working settings under actual load, which means that the solar controller will
exit from the test modewhen exiting the operational interface of the test.
