Scenario

Where does AC coupled unit works?

With Existing On Grid Solar System

By adding the AC coupled storage solution into your exsiting on-grid system, you can store extra solar power from your home system into batteries during the day and use it later when necessary. In this way you can use your solar energy more effectively and save your monthly electricity bill. The system will supply energy to you even the grid is cut off.

Pure Energy Storage without Solar

If there is a big difference between peak-valley price of electricity supply, you can save money or even make arbitrage by using an energy storage system.Simply charge the battery on valley price period and discharge on peak price period.

How AC Coupled System Works

AC coupled storage system is adding the battery storage system to a existing solar on-grid system. A solar on-grid system is generating electricity from the form of DC to AC via solar on-grid inverter. When an AC coupled inverter connects to the same network via AC then it converts the spare energy back into DC and stores in the battery.One of biggest advantages of AC coupled storage is that it turns ANY new or existing solar system a true “battery ready” system. The other main advantage is that for existing solar systems, the investment already made does not need to be wasted by removing the on-grid inverter and replacing it with a hybrid one.

Mode I

During the daytime, the electricity generated by the on-grid system is preferentially supplied to the local home consumption and when there is more electricity produced, it will be charged by the energy storage ystem, if still there is electricity left, the remaining energy will go into the grid.

Mode II

During the daytime, the electricity generated by the on-grid system is preferentially supplied to the local home consumption. If the energy produced is not sufficient, the energy storage system will preferentially release the stored energy and supply to load. And if the power is still not enough, the load will use electricity from grid.

Mode III

During the night, the on-grid system stops working and the energy storage system releases stored energy and supply the home consumption, if the energy is not sufficient, it will be provided from the grid.

Mode IV

In the event of grid breakdown, the on-grid system will stop working due to anti-islanding protection. The energy storage system will supply energy via emergency interface to load.

Mode V

The energy storage system can use the

grid to charge the battery. If the local peak and valley electricity price mode is

adopted, the user can choose to charge

the battery when the electricity price is

low.
