Note: The home storage system can be connected to the router via Wi-Fi or an Ethernet cable.

Install the PV input cable, as shown in Figure 2.6-6

Note:

• Before connecting to the inverter, ensure that the open-circuit voltage of the PV array is within the inverter’s specified limits.
• Before connecting, ensure that the polarity of the PV array output voltage matches the “DC+” and “DC-” symbols.
• Use approved PV system DC cables.

Select a suitable DC cable and strip the wires out by 7±0.5mm. Please refer to the table below for specific specifications.

	Cable Type	Cross-Section (mm2)
		Range	Recommended Value
	Industry-standard Photovoltaic Cable	4.0-6.0(12-10AWG)	4.0（12AWG）

• Retrieve the DC terminals from the accessory pack. Unscrew the nuts to disassemble them and remove the waterproof collar.
• Pass the stripped DC cable through the nut and the waterproof collar.

• Connect the wire part of the DC cable to the metal DC terminal and crimp it with a special DC terminal crimping tool.

• Insert the crimped DC cable into the DC terminal firmly, then insert the waterproof rubber ring into the DC terminal and tighten the nut.

• Measure PV voltage of DC input with multimeter, verify DC input cable polarity.

As shown, Connect the wired DC terminal to the inverter as shown in the figure, and a slight “click” is heard to prove the connection is correct.

Notes:
If DC inputs are accidentally reversely connected or inverter is faulty or not working properly, it is NOT allowed to turn off the DC switch. Otherwise it may cause DC arc and damage the inverter or even lead to a fire disaster.

The correct actions are:

•  Use a clip-on ammeter to measure the DC string current.
• If it is above 0.5A, please wait for the solar irradiance reduces until the current decreases to below 0.5A.
•  Only after the current is below 0.5A, you are allowed to turn off the DC switches and disconnect the PV strings.
• In order to completely eliminate the possibility of failure, please disconnect the PV strings after turning off the DC switch to avoid secondary failures due to continuous PV energy on the next day.

Please note that any damages due to wrong operations are not covered in the device warranty.
