Commissioning

6.1 Commissioning of SPH
Electrify SPH after all installation of Part5 be finished, here are the steps:
1.Connect PV
2.Connect AC
3.Connect battery
4.Turn on PV first
5.Then turn on Grid
6.Last turn on battery
If PV Grid and battery are available, system would work on the "normal" mode.
When the SPH on the normal mode, the screen showing "Normal", LED is green. If
SPH not enter normal mode successful, especially the LCD is red, you need to check
below:
1.Make sure all the connection is correct.
2.All the external switches are on.
3.Inverter built -in switch is on.
4.Make sure the lithium battery is on.
5.Refer to Part 9.1 for correction.
You can refer to Part 6.3.4 for work mode setting, then configure monitor, finish
commissioning lastly.
The SPH inverter will be set to the appropriate model according to the standards of
different countries or regions before leaving the factory. For example, the inverter
shipped to Australia are configured as Australian model in the factory.
Note: The inverter is configured for Australia at the factory.

6.2 Operation modes

6.2.1 Normal mode

Normal mode is working state which including online mode and backup mode.
Online mode
User can set an appropriate priority mode according to request when SPH working
on the online mode. If customer use the LCD and key settings, you can only set one
period, but if you use website settings, you can set up to three periods of the
priority mode. .
(refer to 6.3.4)
1.Load first: Load first is the default mode, when it's working in this mode, PV
energy would offer to load and battery prior; when PV is Insufficient, battery
would discharge; when PV is sufficient for load ,the excess energy would feed to
battery. If there is no battery or battery is full ,the excess energy would feed to
Grid(except anti -reflux ).

2.Battery first: When SPH working in this mode, battery would be charged first, it's
suitable working on the period when the electric charge is low. User need to set
the mode ON and OFF time, and the end time of battery SOC. User can set power
rate which less than the battery maximum output power. If the customer don't
enable the AC CHG (AC grid charging function). Inverter will charge battery by PV
power as large as it can do. If the customer enable the AC CHG (AC grid charging
function). Inverter will charge battery by PV power and AC power from grid as
large as it can do.
3.Grid-first : When SPH working in Grid-first mode, the PV energy would feed to
Grid first. User can choose the period when electric charge is high. User need to set
the mode ON and OFF time, and the end time of battery SOC. User can set power
rate which less than the battery maximum output power.
Backup mode
If Grid lost, system would turn to backup mode (user can disable it, refer to 6.3.4)
and UPS OUTPUT will keep powering the load, all the energy from PV and battery, if
the PV also lost, then only battery discharge. Mind you, SPH maximum output
power is 3600W in this mode, the load which connect with UPS LOAD should less
than 3600W.
Notice:
1. User only can set one period for battery first and Grid first on the LCD,if user
need set more please login shineserver.
2.If user need Grid charge battery, user need input password on the SC surface and
set the AC CHG to enable .

6.2.2 Bypass mode

The SPH's intelligent control system could monitor and adjustment system's status
continuously, when SPH inverter monitoring anything unexpected happen, such as
NO PV and NO battery ,the LCD will display the bypass information, in bypass
mode, the Red LED light will be Blinking. Grid will supply the power to UPS load.
Notice:
If there are some fault in bypass mode. LCD will display error also.
