Off-Grid Storage Solution

In this solution, PV, genset and grid as power source, and use all in one energy storage system for energy storage, dispatching and control, to provide stable and uninterrupted power for household appliances. At the same time, the rational use of this system can also effectively help users in areas with high electricity prices to improve self-consumption rate of PV to reduce electricity bills.

Application advantages

Provide basic power supply in areas without grid

The energy storage system serves as the main power supply. PV or diesel power charge the system at daytime and supply energy to home or outdoor equipment at night when needed.

Provide emergency power supply in areas with unstable grid

The energy storage system works as backup power source, at daytime, PV and grid charge the battery and keep a certain safe power level, supply power to loads such as household appliances and small equipment when grid is gone.

Improve PV self-consumption rate in areas where PV power can’t be output to grid

The energy storage system is used as a dispatching system. During the peak time of PV power generation, it uses the remaining PV power to charge the battery after supplying the load, making full use of PV power, reducing the use of grid power and electricity bills.

In the area with different electricity price at peak and valley time, realize off-peak grid electricity consumption to reduce electricity bills

As a regulating system, the energy storage system makes full use of the grid electricity price rules to reduce household electricity bills. Recharge when electricity price is low, and discharge to supply loads when electricity price is high. Thereby, reduce household electricity bills. In this scenario, with the use of the PV system, which can maximize the use ratio of PV system and optimize household energy structure further.
