6.4 Protective Earth Connection

If the PV inverter in the system is transformerless and the system is connected to the grid without an isolation transformer, the positive and negative poles of the PV string must not be grounded, otherwise the system will not operate normally.
Before connecting the PV string, PV inverter, battery and communication, please make a protective ground connection.
In the PV power generation system, all non-current-carrying metal parts and equipment enclosures need to be grounded. The PE cables of the converter and the PV inverter and the metal frame of the PV array need to be connected to the same ground to achieve equipotential connection. 14

According to the relevant provisions of IEC61643-32, it is necessary to ensure the implementation of lightning protection measure for PV systems
1. Generally, it is recommended to install lightning protection devices (such as lightning rods/ lightning strips and down conductors) to prevent lightning from directly hitting the PV array. 2. Lightning protection devices and down conductors should maintain a safe distance from the related equipment in the photovoltaic system (including PV strings, converters, inverters, cables, and power distribution equipment). 2.1 The recommended value of S: According to the roof of a general 5-story building (approximately 15m), 2.5m is sufficient for S. This distance can be simplified and calculated according to the inverse relationship between the height of the floor. 2.1.1 When the safety distance S is met: As shown in the picture, positions 1 and 3 should be equipped with lightning protection modules. Normally, it is recommended that position 1 pretend to be type II, and position 3 pretend to be TYPE1; 2.1.2 When the safety distance S is not met: In addition to position 3, type I lightning protection modules should be installed in picture 1, 2, and 4;
15

3. The lightning down conductor and the equipment grounding wire eventually converge at a general grounding point, but the two cannot share wires. That is, the equipment grounding wire should be pulled separately, and the wire diameter requirement is> 6mm2 under the condition of meeting the safety spacing distance S;

Lightning protection measures for PV systems should be implemented in accordance with the corresponding national standards and IEC standards, otherwise it may cause cumulative damage to PV devices such as components, converters, inverters, and power distribution facilities. In this case, the company does not carry out quality assurance and assumes any responsibility.

Inspection Item The converter is installed correctly and firmly Ground wire, PV input wire, PV output wire, battery power wire are all connected correctly and firmly Battery communication cable, WIFI connection is correct The waterproof head and waterproof cover are installed correctly and firmly Cable arrangement is reasonable and protected, no mechanical damage No debris scattered in the installation space, enough space for heat dissipation

7.2 Working Mode Introduction
7.2.1 Standby Mode
In this mode, the machine will not run and is in a waiting state. At this time, the converter will continue to accept instructions or detect system parameters, and when conditions permit or settings are changed, the system will try to enter the working mode state.
7.2.2 Default Operating Mode
The default operating mode of LSP100K is as follows: 1. The PVout output terminal outputs to the photovoltaic inverter according to the default 12 channels of 100kW, and the PVin input terminal performs MPPT tracking on the input photovoltaic string and tracks the maximum photovoltaic power generation energy sent to the battery. 2. When the PV input energy is greater than 100kW (the default output power of PVout), the excess energy will be stored in the battery, and the battery capacity will increase.
3. When the energy input by PV is less than 100kW (the default output power of PVout), the excess energy will be discharged from the battery, and the capacity of the battery will decrease. 4. As in article 2 above, if it continues until the battery is fully charged, the system will automatically reduce the PVin input power to a basic equilibrium state with the PVout output power, and maintain a power output of 100kW.
5. As in article 3 above, if it continues until the battery discharges, the system will automatically reduce the PVout output power to slightly less than the PVin input power to keep the battery from entering a powerdeficient shutdown state
7.2.3 fault Mode
Converter’s intelligent control system will continuously monitor and adjust the state of the system. When the converter detects any failure, the alarm or failure LED indicator lights up or flashes red, and the corresponding failure information display can be viewed on the LCD.
