Can the inverter be used 24 hours and 7 days?
Can the inverter be used 24 hours and 7 days?
The answer is no.
Many people will ask why not, and the following will be explained from the perspective of solar panels, batteries, loads, and use environment.
Firstly, the role and position of inverter in solar energy system are briefly introduced. In the off-grid solar system, the components are: solar panel - controller - battery - inverter - load. The inverter is in 4 positions. The use of inverters is affected by other components.
About solar panel, it converts solar energy into electricity under the condition of light, and the load is powered by the solar charge and discharge controller, while the battery is charged.
If you want to convert electricity from solar panels, you need to consider several questions:
1. What is the local solar radiation?
2. What is the load power of the system?
3. What is the output voltage of the system, DC or AC?
4. How many hours does the system need to work every day?
Select the right solar panels to maximize efficiency. Also, the time and intensity of light can affect efficiency. If it is cloudy and rainy, the inverter is mainly powered by batteries, so the battery is required to provide continuous power.
About solar charging controller, it is the brain of the off-grid photovoltaic system, and its function is to charge and discharge the battery. The controller protects the battery from overcharge or over discharge. Overcharging may cause the electrolyte in the battery to vaporize and cause faults, while ove rdischarging may cause premature battery failure. The overcharge and over discharge of batteries may damage the load. Therefore, although the controller will not directly affect the use of the inverter, but will affect the battery and indirectly affect the inverter.
About battery,it supplies power to the inverter. The inverter can work only when the battery has energy. Before use, it is necessary to confirm the capacity, voltage, type, and use status of the battery, and select the appropriate battery to connect with the inverter. It is also necessary to check the status of the battery. Long used batteries and damaged batteries will also affect the efficiency of the inverter.
About load, the load of inverter connection can be divided into resistive load and inductive load. Resistive loads such as light bulbs, TVS, etc. Inductive load is a kind of high-power electrical product made by applying the principle of electromagnetic induction, such as motor, compressor, relay, fluorescent lamp, etc.When the inductive load is switched on or off, the power generated will be 5-7 times larger than the rated power and exceed the rated voltage of the inverter. To ensure the continuous use of the off-grid system, the appropriate inverter should be selected according to the used load and power.
Whether the inverter can be used for 24 hours and 7 days will be affected by the solar panel, controller, battery and load. If you want to use the inverter continuously, you need to choose the right solar system components. If in doubt, you can find the relevant engineer to solve.
