JNGE Power JW2450 User Manual

consumption small, more stable.
Discharge part working mode can be set, light control mode，Period of time
control function ect., The user can set up according to the requirements on its
own combination.
LCD screen and four key operation mode, easy to understand, very
convenient.
Perfect protection function,including:lightning counter-attack,over-voltage
automatic braking, storage battery reverse connect and open circuit protection
Ⅱ. Technical note
1. When battery is fully charged but the charging is still continued by solar or
wind,at this time,we need to do discharge processing, otherwise it may cause
permanent damage to the devices;
2. When the power generation source does not have sufficient power support,
battery may be under-voltage and cannot support for loads normal working.At
this time, we also need to improve the power generation capability,in our wind
solar hybrid system, comparing to the wind generator power, solar power is very
stable power supply, so we had a wind solar hybrid controller mainly for wind

generator and design the booster MPPT charging technology as well as step-less
unloading function. PWM charging technology for solar charge.
Boost MPPT is mainly designed for the situation that most of the time in most
regions where wind energy is not enough to support the generator to generate
electricity to charge the battery. The specific working principle is: the voltage
generated by the fan under the condition that the wind speed does not reach its
rated wind speed, and The power does not reach its rated power. We use the
MPPT algorithm to make the power generated by the fan as much as possible by
collecting the voltage and current of the wind turbine in real time through the
means of a boost circuit to raise the voltage it sends to the charge voltage of the
system battery. Get used.
The step-less unloading function is mainly for the first case. When no
additional energy is needed, the extra energy will be consumed on dump load.
The controller has terminals for connecting the dump load. According to the
actual situation, we suggest that in areas with good wind energy conditions such
as the coast and open area, the dump load must be installed.In the inner-land
area, where wind is very big,we also recommend controller with dump-load.
Ⅲ. Performance characteristics and protection function
◆ Intelligent design, simple structure, powerful control function, stable
performance, product safety and reliability.
◆ Using MPPT fan charging method, the charging efficiency is more superior
than ordinary PWM method
◆Boost charging function solves the problem of low charging efficiency due to
fan's low wind speed (optional)
◆ Use large LCD display, all parameters are visible
Ⅳ. Operating instructions
The installer (user) must have electrical theory knowledge and practical
experience, and strictly in accordance with relevant provisions of the manual
steps and manner.
