About our Products
Solar energy is a clean energy, green and environmental protecting, it makes efficient use of limited resources and reduce CO2 emissions.
The energy conservation and emissions reduction consciousness and demand is growing in the society.
It is the time of well storage and smart usage of household electricity.
POWEROAK household solar power station is not only a simple electricity storage system, but also the combination of electricity system and solar power system, which realized the life of ICT new electricity power.
In the daytime using the electricity charged by AC grid at the night, energy and bill saving.
Charge the solar power storage system at night when less electricity consumption, and in the daytime use the electricity that stored in the night, contribute to restrain power waste.
Connected to solar power generation system, it can supply power directly to household appliances like led lighting ,TV, fridge, air conditioner and so on. or charge the power storage system with the redundant power, to reduce the use of electricity from Grid system.
When there is a power failure, the stored electricity can be used as backup power, the product has the function of UPS.
When there is a power failure, the product act as an emergency power supply for LCD TV and LED lighting, and other important electric application, to ensure continuous output power.
Remote monitoring support
The solar back up energy battery system utilization can be showed on LCD screen, automatic management and alarm. Or you can use portable terminal and realize remote monitor through the internet, safe use.
