Product Introduction:
The household energy storage system adopts a DC coupling mode, ingeniously integrating photovoltaic power generation with energy storage. It can effectively store the excess electricity generated by the photovoltaic system, significantly increase the self-consumption rate of electricity, and notably reduce the reliance on the power grid.
The photovoltaic storage system fully exploits the price difference between peak and off-peak hours to carry out arbitrage operations, selling electricity during peak hours and storing it during off-peak hours, maximizing economic benefits. Not only that, but users can also help share the grid load with the help of this system, and at the same time enjoy policy subsidies related to grid support activities, obtaining considerable economic returns, achieving a good balance between energy conservation and emission reduction and economic benefits.
Product advantages:
· Plug-and-play installation, quick and convenient;
· High protection grade for the entire machine, fearlessly withstands harsh environments;
· Dual-stage lightning protection design for AC and DC, avoiding losses caused by lightning strikes;
· Maximum efficiency of 97.6%.
· Ultra-low start-up voltage, ultra-wide voltage range;
· Multi-channel MPPT design, compatible with high-power mainstream components;
· Supports wireless communication, flexible monitoring methods;
