Step 1: Cut off the distribution circuit breaker at the DC side, and ensure that no
voltage on the wire at DC side.
Step 2: Confirm the battery positive and negative voltage within range with a
multimeter.
Step 3: Confirm the negative and positive pole with a multimeter
Step 4 Peel the insulation layer of cable
Step5: fix cable lug
1. Place the stripped copper core into the crimping holes of the cable lug
2. Press the cable lug with the terminal crimping machine. The number of crimps
should be more than two
Step 6: fix heat shrinking tube
1. choose heat shrink tube according to cable size, and cut aboug 5cm
2. fix the tube to cable, cover the lug hole
3. use air heater to blow the tube and make it shrink
Step 7: Connect the “Bat+” end of the energy storage controller to the positive
terminal of the battery pack with a cable.
1. Pass the cable through the PG waterproof connector.
2. Secure the copper noses at the ends of the wiring to the “Bat+” end of the energy
storage controller and the positive terminal of the battery pack.
3. Fasten the bolt with a screwdriver or wrench
Step 8: Connect the "Bat -" end of the energy storage controller to the negative
terminal of the battery pack by cable according to the method of step 7.
Step 9: Connect the "PV+" end of the energy storage controller to the positive pole of
the battery board by cable according to the method of step 7.
Step 10: Connect the "PV-" end of the energy storage controller to the negative pole
of the battery board by cable according to the method of step 7.
Step 11: Make sure the wiring is secure; tighten the PG waterproof connector
CAUTION!
Caution, risk of danger
When connecting the AC grid, cut off the circuit breaker at the AC side
to ensure that the AC wire connecting to terminals has no electricity.
4.6.4 AC side wiring
Connect AC grid:
1) Cut off the circuit breaker at AC side, to ensure that the AC wire connecting to
terminals has no electricity. Confirm it with a multimeter.
2)confirm the phase sequence of grid
3)peel the insulation layer of cable
4)fix cable lug
5) fix heat shrink tube
1. choose heat shrink tube according to cable size, and cut aboug 5cm
2. fix the tube to cable, cover the lug hole
3. use air heater to blow the tube and make it shrink
6)
1.Connect the L marked at "Grid" of HPS with "L" of the grid .
2.Connect the N marked at "Grid" of HPS with "N" of the grid.
7) same with step 6, connect load cable L and N to the "L" and "N" port of HPS Load.
