System Application Introduction

This product is a household energy storage battery pack. The system is matched with a 5kWh 51.2V 100Ah lithium iron phosphate battery pack.This product can be used in conjunction with electricity so that electricity consumption can be adjusted.This product supports a variety of application modes, such as spontaneous and self-use residual power surfing, peak clipping and valley filling, standby power supply, etc. The specific operation logic is as follows.

PV Self-use Surplus Power to Grid

Under the condition of good illumination in the daytime, the DC power from PV panel is changed into AC through an inverter to supply power for the household load. If the household load cannot run out of photovoltaic power, the remaining power will be stored in the battery.
If the battery is Full charged, photovoltaic power will be supplied to the grid. In the night or rainy days, photovoltaic cannot generate electricity. The battery supplies power to the home load through an inverter. If the battery SOC is low, the household load will take power from the grid.

Peak Shaving and Valley Filling

In some countries and regions where TOU price is implemented, if the difference between peak price and low price is large, the application mode of peak shaving and valley filling can be adopted in energy storage system. In the low electricity price period, the energy storage system is charged; in the peak period of electricity price, the energy storage system supplies power to the household load. It can avoid users using too much power grid when the electricity price is high, and save energy expenditure.

Standby Power Supply

In some extreme weather (such as tornadoes, typhoons, hail), or substation operation failure, power supply will be interrupted. If the energy storage system is installed, the user can still enjoy sufficient power guarantee under this situation.

Abnormal Situation Addressing

1. What if the battery pack does not work properly after power on?

2. A: The most direct way is to connect to the upper computer, through the upper computer to find the fault phenomenon, causes can be roughly analyzed from the upper computer interface prompt alarm, protection, fault and other information, it can also provide necessary reference for further testing.

3. Under what circumstances will RS232 communication fail?
   A: The following steps can be taken to eliminate the problem:

4. Confirm that at least one of the indicator lights of the battery pack is on or flashing, that is, the battery pack is in normal working condition;

5. Confirm that the host computer software selects correct COM port (view device manager);

6. Confirm whether the RS232 communication line is fully inserted into the corresponding communication interface of the battery pack.

7. Under what circumstances will RS485 fail to paralleling batteries communication?

8. A: The possibility of failure of parallel batteries communication is as follows: first ensure whether the parallel RS485 communication port has been connected, and then make sure that the address dialing position of the battery pack is correct, and make sure that the RS485 terminal Plug-in in the right place.

9. What is the fault alarm mechanism?
   A: battery pack has fault alarm function, can be checked through upper computer software. Failure includes:

10. Sampling failure: analog front-end and main control chip communication failure. When the fault occurs, the charge and discharge function is turned off, and the fault alarm can be automatically cleared after the fault is cleared.

11. Temperature NTC failure: mainly detects whether the temperature NTC is short-circuited or disconnected. When the fault occurs, the charge and discharge function is turned off, and the fault alarm can be automatically cleared after the fault is cleared.

12. Cell failure: the voltage diference of the cell exceeds 1V, or the diference between the total voltage detection voltage and the sum of single cell voltage is more than 5V, or the minimum voltage is less than 0.5V. The voltage sampling line disconnect also reports the same fault. When the fault is cleared, the fault alarm can be automatically cleared.

After the battery is connected to the system and shows over-current protection or short circuit protection. This is not a problem with the battery pack, but the capacity load of the electrical equipment is too large. Charging can remove the alarm, or extend the battery pack precharge circuit delay time.
