Pruduct Overview; Mppt - opti-solar SC MPPT series User Manual

Magic series solar controller is based on an advanced maximum power point tracking (MPPT) technology developed,
dedicated to the solar system, the controller conversion efficiency up to 97%.
2.1 It comes with a number of outstanding features, such as:

Innovative Max Power Point Tracking(MPPT) technology, tracking efficiency >99.9%

Full digital technology, high charge conversion efficiency up to 98%

LCD display design, read operating data and working condition easily.

Real-time energy statistics function.

12/24/48V automatic recognition

AGM, Liquid and GEL battery for selection

External temperature sensor, automatic temperature compensation

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

Four stages charge way: MPPT, boost, equalization, float

With current-limiting charging mode, when the power of solar panel is over-sized and charging current exceeds the
rated current, the controller will lower the charging power, which enables the system to work under the rated charging
current

Multiple load control modes: Standard, Dusk to Dawn, Timer and User-defined mode.

Two USB interfaces(EU Series)

Based RS-485 standard Modbus protocol, to maximize their communication needs of different occasions.

Perfect EMC & thermal design

Full automatic electronic protect function
MPPT profile
The full name of the MPPT is maximum power point tracking. It is an advanced charging way which could detect the
real-time power of the solar Module! and the maximum point of the I-V curve that make the highest battery charging
efficiency.
Current Boost
Under most conditions, MPPT technology will "boost" the solar charge current.
MPPT Charging: Power Into the controller (Pmax)=Power out of the controller (Pout)
lin x Vmp= lout x Vout
* Assuming 100% efficiency. Actually, the losses in wiring and conversion exist.
If the solar module's maximum power voltage (Vmp) is greater than the battery voltage, it follows that the battery current
must be proportionally greater than the solar input current so that input and output power are balanced. The greater the
difference between the Vmp and battery voltage, the greater the current boost. Current boost can be substantial in systems
where the solar array is of a higher nominal voltage than the battery as described in the next section.
