Products
How does your solar power station work?
It’s very simple. This is a complete solar power system, through solar panels to absorb sunlight and transfer sunlight energy into electricity, stored electricity in batteries, and through the inverter to transfer DC to AC 220V/110V. People could easily plug home appliance to start use, such as loading air condition, refrigerator, TV and other appliances.
How long does your solar street light work per day?
Usually 12hrs, some could work 3 days even in rainy days.
Do you have half-cut technology solar panel?
Yes sure. Most of our solar panels are made by half-cut technology. We are leader of solar industry and always keep our products upgrade, we hope to try our best to make our quality and service better, to improve your company reputation more greatly.
If the battery is low, will it damage?
If the battery is low, should charge it first. Such as mobile phone, when the phone power is low, people will stop using and charging it first.
What is the difference between MPPT controller and PWM controller?
The MPPT controller has Max.PV open circuit voltage reach 150VDC, charging efficiency 30% higher than PWM, automatically match various voltage of 12V/24V/48V.
The PWM controller is weight light, intelligent and economic, automatically match various voltage of 12V/24V.
What is the difference between hybrid inverter type and other inverter types?
Hybrid inverter is built-in MPPT controller, the other inverter types are not build-in controller, could purchase controller separately.
What is the cycles times of your battery?
For solar lithium battery is 6000-8000 cycle times.
What is the difference between high frequency inverter and low frequency inverter?
High frequency means from about 300Hz down to 50Hz, low frequency is from 0Hz up to 50Hz.
Low frequency inverter comes with large power transformer, stronger and good for loading those home appliances which build-in motor, such as refrigerators, air conditioners, water pumps, etc. High frequency inverter has a small volume, light weight, economic and high efficiency.
Do you do on-grid?
Yes sure. We have been done many government projects such as 1MW, 2MW, 10MW and larger on grid systems. And we could customized solar solution according your requirements.
What is the difference between on grid and off grid?
On grid PV station connects to public grid, it relies on country grid system to work and load household appliances. For the rest power will return to public grid and sell to electric power company. The main accessories are solar panels and solar inverter, no batteries.
Off-grid system is an independent power station, it loads home appliances by solar, and store energy by solar batteries. It’s not restricted by the grid, so it’s ideal for remote areas without grid such as isolated islands and areas that often lack of electricity.
Do you have AGM battery?
Yes sure, the hot selling models are 12v 100ah, 12v 200ah.
What is the difference between gel battery and lead acid battery?
Gel and lead acid are different materials, gel material is more durable and longer lifespan which reach 5-6 years, lead acid battery is 3-5 years.
What is the difference between solar lead acid battery and LifePO4 solar lithium battery?
- Lead acid and LifePO4 are different materials.
- Different lifespan, lead acid battery is 3-5 years and lifePO4 solar lithium battery is 10 years.
- Lead acid battery has excellent performance at both low and high temperatures, and lifePO4 solar lithium battery has high temperature resistance.
- Different warranty, lead acid battery is 12 months and lifePO4 solar lithium battery is 36 months.
- LifePO4 solar lithium battery’s weight is light than lead acid battery.
- Lead acid battery is 85% efficiency and lifePO4 solar lithium battery are 100% discharge.
- Different production technology and internal structures.
