Solar System Controller 30A MPPT Battery Solar Charger (QW-MT30A)
Feature
1. Double crest or multi crest tracing technique design, when the solar panel is under shadow or part of the solar panel is damaged, multi crest will turns up in I-V curve, the controller can still trace the Max. Power point.
2. Built in maximum power point tracking algorithm which could promote the energy utilization efficiency of pv system. The charging efficiency is 15%~20% higher than PWM mode.
3. Adopting sorts of tracking algorithm to track the best working point of the I-V curve promptly and accurately, the MPPT efficiency could reach to 99.9%.
4. Adopting advanced digital power supply technology which make the energy conversion efficiency reach up to 97%.
5. Four stage charging mode: MPPT-equalizing charge-boost voltage charge-floating charge.
6. With current-limiting charging mode, when the power of solar panel is oversized and charging current exceeds the rated current, the controller will lower charging power, which enable the system to work under the rated charging current.
7. Have the fault code indication, it helps user confirm the system fault.
8. It can connect with LCD screen monitoring and the controller parameters is amendable.
9. Various load control methods to improve the system's flexibility.
10. With temperature compensation function to adjust the charge and discharge parameters automatically, which could improve the life of the battery.
11. Various system protection function. Including over-charge, over-discharge, over-load, over-heat, the battery reverse connection protection and so on.
Load working mode specification:
1. Light + time control mode (1-14):
When there has no sunlight, the light intensity will fall to start point, the controller will open the load after confirming the start signal and the load will start work, the load will be closed when the working time reach at the set value. The specific set value meets with the set method of load working mode.
2. Manual mode (15):
Under manual mode, user can control the load by key; No matter it is day or night. This mode applies to special load or deb ing.
3. Debug mode (16):
This mode applies to deb ing; The load will be shut when receiving light signal and it will be on without light signal. The debug mode is easy to examine the validity of the system.
4. Normally on mode (17):
Under this mode, the load will be normally on; This mode is fit for the load which requires 24 hours power supply.
2. What is MPT solar controller?
MPPT solar controller is designed for solar power system design; Equipment can not only efficiently transfer issued by the solar panels to recharge the battery power, but also provides a powerful control functions.
Features: The controller is characterized by intelligent adjustment of the operating voltage solar panels, solar panel always working at the VA characteristic curve of the maximum power point. More common, solar controller, solar panels for power generation increased utilization of 10-30%!
The controller uses solar panels for intelligent charging of the battery. In the solar panel power than the battery storage capacity, the control system automatically cut off the charge, thus ensuring optimum battery charging features, making full use of electricity.
As the battery can only withstand a certain degree of charge current and float voltage, over current and over-voltage charging the battery will cause serious damage. The controller battery charge grams of real-time detection voltage and charging current, and by controlling the charge current to limit the photovoltaic battery charging voltage and charging current to ensure that both the battery is full, it will not be damaged. To increase of the battery service life.
3. Protections.
1. Waterproof protection
Waterproof degree::IP32.
2. Input power limit protection
When the PV power exceeds the rated power, controller will limit the PV power under the value of rated power so as to prevent the controller from being damaged.
3. Battery reverse connection protection
Battery reverse connection will not damage the controller but the system will stop working.
4. The voltage of PV input terminal is over value
When the voltage of PV input terminal is over value, controller will shut the PV input automatically.
5. Short circuit protection of PV input terminal
Load short circuit will not damage the controller but controller will stop output.
6. Over load protection
When the load current exceed 1.25 (or 1.5) time of rated current and last for 10s (5s), the load will stop output.
7. Load short circuit protection
When the load is short circuit, controller will stop output without any damage.
8. Solar panel reverses connection protection
The reverse connection of solar panel won't do any damage to the system.
9. Reverse charging protection at night
Prevent the battery from discharging through solar panel at night.
10. TVS lightning protection
11. Over temperature protection
When inside temperature of the controller is over value, the controller will lower charging power or stop charging.
