Step 1.
Prepare battery cables and accessories, and route the battery power cable through the
battery cover. Use accessories box accessories, battery power cable 50~70mm².
Step 2.
Make battery terminals
,
Strip cable coat, revealing 10mm length of metal core.Use special
crimper to compress battery terminal tightly.

Step 3.
Connect the battery terminal to the inverter. Ensure that the battery polarity is connected
correctly.

4.3 On-Grid & Back-Up Connection
An external AC breaker is needed for on-grid connection to isolate from grid when necessary.
The requirements of on-grid AC breaker are shown as below.

·
The absence of AC breaker on back-up side will lead to inverter damage if an
electrical short circuit happens on back-up side.
NOTE
1.On the AC side, the individual breaker should be connected between inverter and Grid but
before loads.See Figure 4.3-2.
