Growatt SPH4000 Installation Manual

Notice:
1. If you want to use on gird only, please refer to chart 5.17 connect with AC grid and float EPS OUTPUT.
2. If you have no battery now, you can also float BAT terminal, and this hybrid inverter will only work like a
PV inverter.
3. If you want to use both on gird power and backup power, please refer to chart 5.15 and 5.16 connect
with AC grid and EPS OUTPUT like the chart show.
4. On grid terminal and off grid terminal can’t directly connect together.
5. Off Grid terminal can’t connect to grid.
6. If you want to use on gird and off grid, you can use ATS (automatic transfer switch) like chart 5.15 and
5.16 before or ask Growatt for help to connect them.
7. The first start of system needs Grid power.
5.4.3 Connection of battery terminal
