⌈Why I recommend you to use on/off grid energy storage inverters?⌋

Reason 1: Peak clipping and valley filling to help you earning revenue

During the valley period (when the electricity price is low), the grid electricity charge the battery through the inverter. During the peak period (when the electricity price is high), the inverter send full power to the grid electricity. Under the condition of satisfying the load demand, the battery power is also fed to the grid electricity, to achieve the purpose of selling electricity to grid. By using the on/off grid inverter,it is not only reduce the pressure of electricity, but also obtain the economic benefits of peak valley difference in electricity charges.

Peak and valley time periods can be set up by users.

Reason 2: Off-grid power generation, which can be used as a backup power source when the grid electricity is cut off

In the event of a grid electricity failure, the grid-tied mode of the inverter stops working, and switch to off-grid mode automatically, solar power continues to be generated to provide uninterrupted power to the loads, and the remaining photovoltaic energy is stored in batteries

Reason 3: Photovoltaic energy is fully utilized

The system uses PV energy as priority at any working modes,when the energy of PV is not enough, it can be supplemented by grid electricity or batteries. When the PV energy is surplus, the battery is stored or send to the grid, to achieve the purpose of self-use and extra power send to the grid, realize the full use of PV power generation

Reason 4: Both PV/grid electricity can charge the batteries

This inverter is compatible with lead-acid battery, lithium ion and other battery types. Both PV/grid electricity can charge the batteries with 3 section/2 section charging mode, it can prolong the battery service life.

Reason 5: Auto power on, convenient for unattended operation

In the state of grid electricity power supply and photovoltaic power supply, the inverter automatically starts up to facilitate the power management in the case of unattended.

Reason 6: High inverter efficiency, Innovative technology

There is no loss when grid electricity supply power to the loads through inverter. When photovoltaic and battery supply power to loads, the inverter loss is less than 10%, leading among peers.

⌈Inverter How to Use⌋

 

Here I introduce how to use the inverter:

Main working modes shown as below according to different status and condition. AC/DC switching key (the key is at the back of the inverter). If you select AC, the priority mode will be the grid electricity supply ; If you select DC, the priority mode will be the battery supply.

1)  AC mode

1 When the grid electricity is normal and the current solar power generation is bigger than the load power, solar power will feed the load completely and the surplus solar power will feed the battery and transmit to the grid.

2 When grid electricity is normal and the solar power is smaller than the load power, the insufficient part is supplemented by the grid electricity; The solar and the grid electricity feed the load together.

3 When grid electricity is abnormal, the inverter changes to independent invert mode. When the solar power is bigger than the load power, the solar power will feed the load completely, and the surplus part will charge the battery. When the solar power is smaller than the load power, the insufficient part is supplemented by the battery; the batteries and the solar feed the load together.

4 When solar has no generating power, the grid electricity will charge and store energy to the battery through the inverter.

5 When grid electricity is abnormal and there is no solar, batteries will feed the load.

2) Battery mode

1 When the grid electricity is normal and the current solar power generation is bigger than the load power, solar power will feed the load completely and the surplus solar power will feed the battery and transmit to the grid.

2 When the solar power is smaller than the load power, the insufficient part is supplemented by the battery. The solar and the battery will feed the load together.

3 When solar power runs out or very little and the battery is placed to below 48 volt/96 volt/192 volt/240 volt (Depends on different solar system voltage), the discharge power of the battery will be linearly reduced. The insufficient part will be supplemented by grid electricity. And when it reaches the low-voltage protection of the battery, the load will be completely feed by the grid electricity.

4 When grid electricity is abnormal, the inverter will work in the independent invert mode. The solar power will feed the load. And if the solar power is insufficient, it is supplemented by the battery.

Note: under the BATT mode, if there is no solar, grid electricity won’t charge the battery.

3) Peak-cutting and Valley-filling of power-using Mode (This mode needs to work in battery priority mode)

This mode is suitable for the areas which have peak and valley electricity price. According to the electricity price in different periods, the corresponding time can be set to charge and discharge from the grid.

1 When the electricity price is low, grid electricity charges the batteries;

2 When the electricity price is high, the batteries feed the loads.
