MPPT solar controller 48V40A
operating principle
MPPT function
1.Normal Solar Charge Controller: solar panel works at point A, solar panel working voltage is a little higher than battery voltage
Charge Voltage: UA=13.2V
Charge Current: IA=9.8A
Charge Power: PA=13.2*9.8=129.36w
Area in drawing: 1+3
2.MPPT Solar Charge Controller: solar panel works at point B, the solar panel working voltage much higher than battery voltage.
Charge Voltage: UB=18.4V,
Charge Current: IB=9.3A
Charge Power: PB=18.4*9.3=171.12w
Area in drawing 1+2
Comparison: The power B is more than power A.
P/ PA =(PB— PA)/ PA=32.3%
Features
1.We adopt the principle of MPPT and advanced Microprocessor Controlled and
DSP technology.
2.Improve PV system output efficiency of 20%-30%.
3.Wide input DC voltage range
4.Digital intelligent control, use light signal transmission to control signal inner
system for transfer with protection from interference and power loss
5.Solar controller charge module with electric plug, which is more convenience for
adding adequate capacity maintenance
6.Battery charge control adopt three stags eg, equilibrium, boost, and float
7.DC and AC power distribution cabinets designed with lighting protection,
connecting wires could come out from the top or bottom which is easy to connect.
8.When the temperature is 50℃, system will reach rated output.
9.High reliability, no need for maintenance, lifetime up to 20 years
10.LCD display which shows PV voltage, charge voltage and charge current
11.ISO9001:2000

Company introduction
Foshan Ouyad Electronic Co, Ltd was founded in 1998, covering area more than 20, 000
square meters. The headquarters are located Building 4, Area D, New lighting Source Industrial Base, South Luocun Road, Luocun Town, Nanhai District, Foshan City, Guangdong Province, China.
We have our own independent wind turbine manufacturing plant and R&D department of wind turbine generator control system, solar panel, grid tie inverter, off grid inverter, controller, battery, etc.
At an early time, our company was famous for producing a variety of inverters at home and abroad. In 2005, we began to R&D and produce new energy products, R&D generator, and obtain great success, with 15 terms of new patents have been reported.
Depending on powerful technical strength and many years manufacturing experience, Ouyad has rapidly developed into a new energy manufacturer focused on wind power generation system and solar power system.
In the year of 2010, our company established Marketing Service Center in Washington, America, and our products are authorized by CE test system and the ISO9001: 2000 international quality system certification. UL certificate is being tested.
In the year of 2014, ouyad company are well known as Guangdong Province High Technology Corporation.
