Notice:
1.If you want to use on gird only, please refer to chart 5.24 connect with AC grid and
float UPS 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 5.22 and 5.23 connect with AC grid and UPS 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 TSSP (transfer switch single
phase) like chart 5.22 and 5.23 before or ask Growatt for help to connect them. TSSP
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. Turn the TSSP to Gird to keep UPS load having
power.
7.Max UPS load should be less than 3680W.
8.The first start of system needs Grid power.

Install battery steps are as follows:
1.Unscrew the swivel nut from the cable gland.
2.Thread the swivel nut over the battery cable.
3.Press the cable support sleeve out of the cable gland.
4.Remove the filler plug from the cable support sleeve.
5.Route the network cable through an opening in the cable support sleeve.
6.Thread the network cable through the cable gland.
7.Thread cables into connection terminal, then press the terminal by relevant tools
and make sure battery cables are firmly (Growatt lithium battery contains a battery
cable in the original packing).
8.Connect positive pole (+) of battery cable to battery positive terminal (+) of the
inverter, connect negative pole (-) of battery cable to battery negative terminal (-).
9.Continue to install other cables.
