Greencisco Industrial Co., Ltd.
MPPT Solar Charging Controller
MPPT solar controllers are widely used for solar power systems, solar street lights,ect.
Introduction
Solar controller work by DC/DC conversion, charging circuit and main control circuit to realize the automatic charging management of storage batteries and solar panels.Widely used in solar power system, solar street lights,etc. 
Features
●Built-in maximum power point tracking algorithm which could promote energy utilization efficiency of PV system. The charging efficiency is 20% higher than PWM mode.
●MPPT efficiency could reach to 99.9%
●The use of advanced digital power technology, circuit energy conversion efficiency is as high as 98%
●Four stage charging order mode: MPPT-equalizing charging-boost charging-float charging 
●With current-limiting charging mode, which enables system to work under the rated charging current.
●With RS232 interface,it can communicate with PC by communication wires and cables, read or set controller’s running parameters and monitor the system operation status.
●With the fault code indication; it helps users confirm the system fault
●With 384VDC
●Support data storage for 5 years.
●It can connect with LCD screen monitoring and the controller parameters are amendable.
●Built-in temperature sensor, when the temperature exceeds the set value, the charging current will lower down followed by the decrease of temperature, so as to control the controller’s temperature rise.
●With temperature compensation function to adjust the charge and discharge parameters automatically, which can improve battery service life.
●With protection functions of overcharge,overdischarge,overload,overheat and battery reverses connection protection.
