A violent typhoon in Philippines destroyed homes, uprooted trees, and left residents without power. The electricity was cut for almost a Month. There was no light in the streets and the whole island was covered with darkness. The Sunmaster poles, powered by renewable sources and thus independent of the electrical grid, managed to withstand the storm giving them light and hope for several weeks.

Frequently Solar Street Lights Questions & Answers

Solar street light

  • Which are the information you should give us to best customize our solar lights?
    1. The sunshine hours per day or the exact city the street lights will be installed
    2. How many continuous rainy days in the raining season there? (It matters because we have to make sure the light can still work in 3 or 4 raining days with little sunshine)
    3. The brightness of LED lamp(50Watt, for example)
    4. Working time of solar light every day(10 hours, for example)
    5. The height of the poles, or the width of road
    6. It is best to offer the pictures on the locations where the solar lamps going to be installed.
  • What is a sun hour?
    A sun hour is a unit of measurement of the intensity of sunlight on the earth at a given time that can be used for generation of solar power, recognizing factors such as climate and weather. A full sun hour is measured as the intensity of sunlight at noon, whereas less than a full sun hour will result during the hours before and after noon.
  • What happens if there are cloudy days?
    Electrical energy is stored in the battery each day, and some of that energy is used to operate the light at night. Generally, we design your system so that the battery will operate the light for five nights without charging. This means that, even after a series of cloudy days, there will be plenty energy in the battery to power the light each night. Also, the solar panel will continue to charge the battery (although at a reduced rate) even when it is cloudy.
  • How does the light know when to turn on and turn off?
    SunMaster’s solar controller uses a photocell and/or timer to control when the light will turn on, when the sun goes down, and to turn off when the sun comes up. The photocell detects when the sun comes down and when the sun comes up again. SunMaster can make the lamp last anywhere from 8-14 hours, and this varies on the customer’s needs. The solar controller utilizes an internal timer that is pre-set for a specific number of hours to determine when to switch the light off. If the solar controller is set to leave the light on until dawn, it determines when the sun rise (and when to switch the light off) by means of voltage readings from the solar panel array.
  • What is the typical maintenance schedule for a solar lighting system?
    There is no regular maintenance required for a solar lighting system. However, it is helpful to keep the solar panels clean, especially in a dusty climate.
  • Why SUNMASTER advises to use 24V for 40+W Solar LED System?
    Our suggestion for using 24V battery bank for solar LED system is based on our research which we conducted earlier before launching our Solar LED system. What we did in our research was that we actually tested both the systems 12V battery bank and as well as 24V battery bank. Read more ->
  • What do we need to know to customize your solar light project?
    In order to customize your solar light project the first thing we need to focus on is the location for installing the solar power lighting system and the perfect location where you want to install your solar light project, because different locations and surface have different levels of sunlight which can have an impact on the outcome of the solar light project.

  • Do I have to charge the batteries?
    Batteries are shipped 85% charged. The batteries will be at 100% charged within two weeks of proper operation.
  • What is a Gel Battery (VRLA Battery)?
    Gel battery also known as VRLA (valve regulated lead-acid) batteries or gel cells, contains acid that has been gelled by the addition of silica gel, turning the acid into a solid mass that looks like gooey Jell-O. They contain less acid than a regular battery. Gel batteries are commonly used in wheelchairs, golf carts and marine applications. There are several advantages to using gel batteries. Read more ->
  • What are Solar Lights?
    If Scientifically define, Solar lights are portable light fixtures composed of LED lamps, photovoltaic solar panels, and rechargeable batteries. Read more ->
  • How many hours need to install Solar/Wind Led street light?
    Installing a solar or wind powered LED street light isn’t any sort of rocket science, in fact anyone willing to install by himself can do it easily. Read more ->
  • What's the matter with the better weather and less power generation?
    The power generation of photovoltaic power stations in summer may not be as high as that in spring or autumn, because the continuous high temperature in summer has a great impact on the modules. When the temperature increases, the output power of the module will decrease. For each degree of increase, the power generation will decrease by about 0.44%.
  • How to calculate the voltage and current?
    The string voltage is calculated according to the full load MPPT of the inverter; The string current shall not be greater than the maximum input current of the inverter.

    The string voltage is calculated according to the full load MPPT of the inverter; The string current shall not be greater than the maximum input current of the inverter.
  • Can 5kW household inverter be compatible with 540 components?
    The peak current of 540 components is less than 13a, and the maximum string current of sunmaster single-phase 5kW inverter is 13a, which can be matched. Through the calculation of voltage and other parameters, the inverter can also achieve a very good over configuration state.
  • Cut off the mains power and the inverter is not turned off, but what is the reason why there is power on the zero line?
    The zero line is disconnected and ungrounded. It is not zero potential. The voltage is induced by the live line, or the voltage of the live line is transmitted to the zero line through electrical appliances, so the zero line is charged.
  • How to deal with zero line electrification?
    Common causes and treatment measures of zero line electrification: 1) There is leakage of electrical equipment on the line, and the end action of the protection device makes the zero line live. Power off for maintenance, find out the leakage equipment for repair, and find out the reason for the end action of the protection device. 2) One phase of the line is grounded, and the general protection device in the power grid is not protected, making the zero line live. After power failure, first measure the line with a megger to see if there is any place with poor insulation. During measurement, pay attention to the disconnection of instruments in the line. 3) The zero line is broken. There is leakage or large single-phase load operation in the electrical equipment behind the fracture, which makes the zero line live. After power failure, test whether the zero line is broken, and find and repair the broken line. 4) In the neutral grid, some electrical equipment are protected by grounding and leakage, so that the zero line is charged. Distinguish whether the system is connected to neutral system or grounding system, or repeated grounding in the neutral system. Then install the ground wire correctly. 5) In the neutral grid, single-phase electrical equipment adopts "one fire and one ground", that is, there is no working zero line to make the zero line live. When installing n-wire, PE wire cannot be used as n-wire. 6) The insulation resistance of some electrical equipment in the power grid has been damaged and leakage, making the zero line live. Check the equipment whose insulation resistance does not meet the specified requirements and repair it. 7) The working grounding connection at the low-voltage side of the transformer has poor contact and large resistance. When the unbalanced current of three-phase load exceeds the allowable range, the zero line will be charged. If it is difficult to find the poor contact, it shall be repaired every year or at the specified time. It is not allowed to be lazy. It shall be repaired according to the regulations. 8) The high voltage flows into the low voltage, making the zero line live. It's hard to find, and sometimes there are big problems. The most difficult one is dangerous to people. Be sure to operate according to the operating procedures. 9) The high voltage adopts the operation mode of two lines and one ground. When the grounding body is too close to the low-voltage working grounding or repeated grounding body, the voltage drop on the high-voltage working grounding will affect the working grounding at the low-voltage side and make the zero line live. Find out the cause and lay according to the corresponding regulations. 10) 10. The zero line is charged due to magnetic field induction. 11) The zero line is charged due to electrostatic induction. 12) Due to the partial voltage effect of insulation resistance and capacitance to ground, the shell of electrical equipment may be charged.
  • If the voltage of each string is not exceeded, will the power exceed? For example, 15kw inverter 3-way MPPT, 5kW each way, is this right?
    In general, the designed component power usually exceeds the rated power of the inverter, and the voltage will not exceed the maximum system voltage of the inverter. 15kw inverter, if it is a three-way inverter, can be designed into two strings or three strings, which can be designed to exceed the rated power of 15kw.
  • Is the inverter grounded at the same place as the enclosure grounding?
    Inverter grounding and shell grounding are not connected at the same place and need to be separated. The former is working grounding (can maintain the non fault phase to ground voltage unchanged; can ensure the accuracy of relatively low voltage measurement in the primary system; discharge lightning current to the ground during lightning stroke), and the latter is protective grounding (in order to ensure personal safety and avoid or reduce the harm of accidents, protective grounding is often used in Electrical Engineering).
  • How much cable is the 40kW inverter equipped with?
    YJV 3x16 + 1x10mm is recommended ².

Administration

  • Which types of warranties you will have?
    Solar Panel: mininum 25 years of power generation capacity, with 10-years warranty LED Light: Mininum 50.000 hours life span, with 2-year all inclusive warranty - covers everything on the LED street lights, including lamp holder parts, power supply, radiatior, scaling gasket, LED modules & lens Battery: 5 to 7 years life span, with a 2-year warranty Controller inverter and all the electronic parts: Minimum 8 years by ordinary usage, with a 2- year warranty Pole solar panel bracket and all the metal parts: up to 10 years life span
