New On-grid Photovoltaic Energy Storage System
In countries and regions with relatively expensive power, more and more people select photovoltaic energy storage system. In the system, battery is fully charged when the inverter detects photovoltaic power is higher than load power; battery discharges when load power is detected as higher than photovoltaic power generation. The system can set discharging time to ensure energy is stored in lithium battery and will be discharged in peak period to save power charge to the maximum extent.
Expanded On-grid Photovoltaic Energy Storage System
Since follow-up grid-connected power generation cannot bring more benefit, it will be an ideal choice to improve the self-use rate of photovoltaic energy. The system is compatible with modification of any existing photovoltaic system and upgrades it to photovoltaic energy storage system.
Off-grid Photovoltaic Energy Storage System
Under the circumstance, the system supplies all power for household appliances and is applicable for regions without power or with extremely unstable power. All or most power is from the photovoltaic system. Output power of the photovoltaic system first meets application requirements of household appliances and extra energy is stored in the battery system. The battery system supplies energy in case of nighttime or insufficient photovoltaic power generation system.
Back-up Energy Storage System
With some regions unstable power supply, easy to suffer power interruption, household appliances cannot be unable to operate normally. For instance, a refrigerator cannot keep food fresh after its power outage, causing food spoil. The photovoltaic system cannot be placed around houses. The system can charge the battery system through commercial power and supply power to significant household appliances automatically in case of commercial power outage.
