5.4.3 Connection of battery terminal
Similar to the traditional inverter connecting, the input of battery can be realized by
using MC4 terminal, the detail steps are as follows:
Step 1: Turn off battery switch.
Step 2: Insert battery panel positive and negative cables into MC4 terminal
，
then
connect positive pole(+) of connection cable to positive pole(+) of battery input
connector, connect negative pole(-) of connection cable to negative pole(-)of battery
input connector.
Please pay attention to battery input voltage and current within permission Limit:
Ø
Max battery voltage: 550V
Ø
Max battery input current: 25A
Ø
Max battery input power : 10000W
Remark:
We suggest you use the cable
≥
4mm2/10 AWG to connect.
Note:
We suggest the distance between battery and SPA no longer than 5m, and The power
line area must be larger than 10AWG.
