Note:
This diagram is an example for customer who only wants to use the off grid storage
system.
1. If you want to use on gird only, please refer to chart 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 uninterrupted power, please refer to chart
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 (transfer switch single
phase) like chart before or ask Growatt for help to connect them. ATS is using to switch
when SPH is not working or in fault mode. For example: if SPH is in fault mode but
there is Grid power. ATS will turn to Gird to keep Critical load having power.
7. Max EPS load should be less than 3600W.
8. The first start of system needs Grid power.
