Features:
We adopt the principle of MPPT and advanced Microprocessor Controlled and DSP technology.
Improve PV system output efficiency of 20%-30%.
Wide input DC voltage range.
Digital intelligent control, use light signal transmission to control signal inner system for transfer with protection from interference and power loss.
Solar controller charge module with electric plug, which is more convenience for adding adequate capacity maintaintenance.
Battery charge control adopt three stags eg, equilibrium, boost, and float.
When the temperature is 50°C, system will reach rated output.
High reliability, no need for maintenance, lifetime up to 20 years.
LCD display which shows PV voltage, charge voltage and charge current.
ISO9001:2000.
