6 Commissioning

6.1 Commissioning the SPH

Upon completion of installation and electrical connection, power on the SPH system in the

following steps:

Ø Connect the PV side

Ø Finally, turn on the PV side

Ø Turn on the battery

Ø Turn on the AC breaker

Ø Connect the AC side

Ø Connect the battery side

When the SPH is operating normally, the screen displays "Normal" and the LED indicator

would be green.

In case that the SPH fails to work in the normal mode and the indicator turns red, please

check the following items:

Ø Ensure that the battery is on.

Ø All cables are properly connected.

Ø Refer to Part 9.1 for correction

Ø The inverter's built-in switch is on.

Ø All external switches are on.

For details about setting the working mode, please refer to Section 6.4.4.

6.2 Operation modes

6.2.1 Normal mode

In normal mode, the SPH can operate in the on-grid mode, or supply backup power

during a grid outage.

Users are allowed to configure the time periods to operate the SPH in the on-grid mode.

On the LCD screen, you can set only one period; while on the Growatt Server website, you

can set up to three periods to specify the working mode. For details, please see Section

6.4.4.

Battery first: In this mode, the power is prioritized towards charging the battery. It is

recommended to select this mode during low electricity price periods. You need to set the

ON and OFF time of each period, the charge cutoff SOC and the charge power, which

should not be greater than the battery maximum input power. If the AC Charging (charge

from grid) function is disabled, the SPH will charge the battery with solar power as a

priority. If enabled, the SPH will charge the battery will both the solar power and the

power drawn from the grid.

Load first: the default mode. In this mode, the solar power is prioritized to power the

loads. When the solar power is insufficient, the battery will discharge to support the

loads. If the solar power is sufficient, the surplus power will be directed to the battery. If

no battery is connected or the battery has been fully charged, any further surplus energy

will be fed to the grid (expect that the export limitation is enabled).

Grid first: In this mode, the solar power and the battery energy will be fed to the grid first.

You are advised to choose this mode during high electricity price periods. You need to set

the ON and OFF time of each period, the discharge cutoff SOC and the discharge power,

which should not be greater than the battery maximum output power.

Ÿ On-grid mode

Ÿ Backup mode

If you want to charge battery from grid, you need to enter the password on the LCD screen

and set AC CHG to "Enable".

In the event of a grid anomaly or grid outage, the inverter will switch to the backup mode,

supplying power to critical loads with the battery and PV energy via the EPS output. You

can disable the backup function following instructions in Section 6.4.4. If the PV power or

the battery energy is loss, the other energy source should supply power. Please note that

the maximum output power of the SPH in backup mode is 10000 W. Therefore, the load

power connected to the EPS output port should be less than 10000 W.

Users can set only one period for Battery first or Grid first working mode on the LCD

screen. To configure more periods, you can log into the Growatt Server webpage.

Note:

6.2.2 Fault mode

The SPH's smart management system monitors the system in real time. In case that any

exception is detected, such as a system fault or an inverter fault, the LCD screen will

display the fault information with the LED indicator turning red.

Note:

Ø For detailed fault description, please refer to Section 9.1.

6.2.3 Programming mode

In the Programming mode, the SPH is updating and it is not allowed to cut out the power

during the update process. The SPH will switch to the normal mode once the upgrade is

complete.

6.2.4 Checking mode

Before the SPH enters the normal mode, the inverter will perform self-check. Once all tests

are passed, the system will enter the normal mode; otherwise, it will enter the fault mode.

6.2.5 Standby mode

The SPH enters the standby mode when no fault has been detected while the operating

requirements are not met.

When the other inverter (excluding the SPH) is present, the inverter output and the

battery energy are prioritized to support the loads. The excess power will be fed to the

grid.

When no other inverter is installed or the solar energy is insufficient, the battery will

discharge to support the loads and the excess power will be fed to the grid.

Ÿ Bypass mode

When the SPH is only connected on the AC side with no connection to the battery and the

PV panel, the SPH can be powered on and it will enter the Bypass mode.
