Product Description

Home Use Customized Solar Power System High Quality Solar Off Grid Systems




Photovoltaic power generation system refers to a power generation system that directly converts light energy into electrical energy without a thermal process. Its main components are solar cells, storage batteries, controllers and inverters. It is characterized by high reliability, long service life, no environmental pollution, independent power generation and grid-connected operation.

    Note: 1. The inverter has sufficient power output, and the cumulative use function of the above appliances shall not exceed 3KW (inductive load discharge 3-5 times the power)
    2. The above electricity consumption is only a reference value. We cannot promise and guarantee that power generation in various regions will be affected by light conditions. There will be slight differences, please be aware!




Question 1: Why can't the test current with a multimeter reach the nominal current?
A1: Because the short-circuit current is a parameter to measure the quality of solar cells, this parameter can only be used with a module tester
It can be tested, and the multimeter itself is the load, so the tested parameter is the working current, please do not misunderstand. Solar cell
Test conditions: 1000W/m2 illuminance cell temperature 25 degrees Celsius AM1.5 (atmospheric transparency), our solar panels are in
The test under standard bright light is a theoretical concept, and the actual effect will vary according to the buyer’s area, the weather and the degree of pollution will be moderate.
Question 2: How much power can be driven by solar panels?
A2: This depends on the battery capacity of the customer terminal and the power of the inverter. This has nothing to do with the solar panel, which is just
Responsible for charging your battery, it does not store electricity, solar energy is responsible for charging the battery, and the battery discharging the electrical equipment. This is
A charging and discharging process.
Question 3: Can solar panels be used on cloudy days?
A3: It depends on the intensity of the light in cloudy/rainy days. If the light is strong, there will be weak current and voltage, which can generate about 10% of the electricity.
force. But this is several times or even hundreds of times worse than that under bright sunlight on a sunny day! In short, the stronger the light, the better the power generation effect.
The weaker the line, the worse the effect.
Question 4: Can solar panels work without a controller?
A4: It is best to use a controller, or it is necessary to use a controller. The function of the controller is to control the
To protect the battery from over-discharge, short-circuit protection, etc. If the controller is not used, the solar panel will be
At the same time, the voltage rise and fall are different, thus affecting the charging voltage and current of the battery. Even charge the battery!
Question 5: How to maintain the battery?
A5: When the battery has not been charged and discharged for a long time, the user needs to charge and discharge once every 3-4 months, and the charging time shall not be allowed each time.
Less than 12 hours, the battery needs to dissipate heat during operation, so it should be placed in a cool and non-humid place.
