Notice:
1.If you want to use on gird only, please refer to chart 5.15. connect with AC grid and
float EPS OUTPUT.
2.If you want to use both on gird power and back up power ,please refer to chart
5.16. connect with AC grid and EPS OUTPUT like the chart show.
3.On grid terminal and off grid terminal can't directly connect together, if directly
connected together, it will cause damage to inverter!
4.Off Grid terminal can't connect to grid. If there is grid power, it will cause damage
to inverter!
