2. Full-automatic intelligent work, commonly known as automatic charging in the daytime (or in the relevant analog environment), and lighting at night (or in the relevant analog environment).

3. From the perspective of internal technical procedure control: when the sun shines on the photovoltaic panel (or other time environment) in the morning, making the voltage of the panel reach a certain threshold (now our company sets 5V), the photovoltaic panel will charge the battery. When the sun slowly weakens in the afternoon (or other time environment), when the voltage of the panel is lower than a certain threshold (now our company sets 5V), the battery will start to discharge and the street lamp will start to light up.

4. Take M series as an example, the mechanical switch determines whether the lamp can start charging and discharging.

The light control determines the time when the discharge starts (the lamp lights up), and the light control and time control determine the time when the discharge ends (the lamp automatically goes out) -- the principle of first come, first served.

The brightness of the whole lamp during the lighting period is determined by the sensor and the relevant timing light mode.

Question 47

If the customer needs 100 sets of FX-80W, what is its weight and volume?

Accepted Answer

lamp holder packaging size/piece: 1610 * 90 * 440mm, battery box packaging size: 620 * 370 * 140mm

(1.61 * 0.09 * 0.44m) * 100 sets=6.38 CBM, (0.62 * 0.37 * 0.14m) * 100 sets=3.21 CBM

CBM: 6.37cm+3.21cm=9.59cm

G. W weight: 8.5kg * 100 sets=850kgs, 12.6kg * 100 sets=1260kgs

total weight:850+1260=2110kgs

When you ask Manager Liu about the freight, you should inform him of the model, quantity, volume, weight, whether there is a tray, and confirm the size and weight of a single piece of the tray, the specific address+postal code (express door-to-door, postal code is used to confirm whether there is a remote area, and there is a remote area charge)

Airport name (air transport)

Seaport

Recommend appropriate freight to customers according to their situation. If CBM almost meets the standard of the whole container, recommend the use of the whole container to customers.

Benefits of the whole cabinet:

1. The stacking method of goods can be controlled. Bulk goods cannot guarantee that others' goods do not weigh our goods. If there are heavy objects stacked on our products, it may cause product damage (mainly solar panels, because the solar panels are tempered glass, which is fragile).

2. Because the freight is the same (the premise is that the whole container is not overweight after loading, there will be an overweight fee for overweight or it can't be shipped. Generally, there is only light, and it won't be overweight. Pay attention to the problem of overweight when adding light poles).

3. The port of destination cost of the whole container is cheaper than that of the same bulk cargo.

Note: For CFR goods, the freight in CIF is not necessarily higher than that of the whole container for goods with the same CBM.

If the current installation is 6 meters high, the test illuminance is 38 lux, and the calculation formula for the installation of 8 meters high is ((6 * 6)/(8 * 8)) * 38=21.3 lux.

Question 55

What are the advantages of MPPT compared with PWM?

Accepted Answer

PWM and MPPT controllers have their own unique advantages and disadvantages. The choice of the scheme depends on the design characteristics, cost and external environment of the solar photovoltaic array. When we choose, we should focus on the following factors:

1) MPPT controller is more expensive than PWM controller, however, MPPT controller has higher charging efficiency, especially in cold weather conditions. MPPT controller also supports more photovoltaic (PV) panels wired in series (high voltage differential), which is also its major advantage. In this case, the cross-sectional area of the connecting cable can be greatly reduced, thus reducing the overall cost of the system.

2) Compared with MPPT controller, the biggest disadvantage of PWM controller is efficiency. PWM charging controller can not charge the maximum power generated by photovoltaic (PV) array. Its overall efficiency is usually between 65-85%. On the other hand, MPPT controller can ensure that the solar array is always in the best operating state. In some cases, such as cold weather, the charging efficiency provided by MPPT mode is 30% higher than that of PWM mode (high charging efficiency).

3) PWM mode has mature technology, simple and reliable circuit and low price, but the utilization rate of components is low. It is suitable for small systems. The temperature range of solar charging unit is 45-75 ℃. MPPT controller is a better choice for large systems, and its higher efficiency means good economic benefits. In addition, the MPPT controller supports users to obtain the maximum power from the photovoltaic (PV) array. When there is additional power demand and the space is limited, the size of the PV array cannot be expanded, the MPPT controller has obvious advantages in this case.

Question 56

What is the FX light mode? And what's the smart power function?

Accepted Answer

FX series has four lighting modes: L, T, M, U

L: 12 hours full power on.

T: 4 hours full power+8 hours 25% brightness.

M: 12 hours of motion sensor control (full power when people and cars pass by, switching to 25% after 30 seconds).

U: 4-hour full power+8-hour motion sensor control.

1. Intelligent regulation power description:

The smart power will be started when the power in the battery is less than 40%. The smart power is set in 10 stages to save energy. The first stage is that the power will be reduced to 90% when the power is between 40% and 37%, and the second stage is that the power will be reduced to 80% when the power is between 37% and 34%, The third stage is that the power will drop to 70% when the power is between 34% and 31%, and the fourth stage is that the power will drop to 60% when the power is between 31% and 28%, The fifth stage is that the power will be reduced to 50% when the power is between 28% and 25%.

The sixth stage is that the power will drop to 40% when the power is between 25% and 22%.

The seventh stage is that the power will be reduced to 30% when the power is 22% - 19%.

The eighth stage is that the power will drop to 20% when the power is between 19% and 16%.

The ninth stage is that when the power is between 16% and 13%, the power will drop to 10% of the previous one.

The tenth stage is that the power will be reduced to 5% when the power is between 13% and 10%.

2. There are three factors that determine the brightness of solar street lamps:

① Wattage of LED (power size)

② Remote control

③ What is the remaining capacity of the battery

The important factor is the first and second point.

Question 57

How long does FX normally charge?

Accepted Answer

5-6 hours (6-10 hours) in sunny days are based on the price list.

Add: It depends on the local environmental factors. Sometimes it will be charged in cloudy days, which does not mean that it is not charged at all. The automatic switch of solar street lamp is controlled by light control+time control. The principle is that the controller sets the light-controlled voltage, which is 5v by default. The intensity of the external ambient light on the solar panel is different. When the sunlight is the strongest, the voltage on the solar panel is the highest. The light gradually darkens, and the voltage of the solar panel will also slowly decrease. When the discharge voltage is lower than 5v, the street lamp will automatically turn on, and when it is higher than 5v, the street lamp will automatically turn off.
