Commissioning 6
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 AC first
5.Then turn on battery
6.Last turn on PV
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.
6.2 Operation modes
6.2.1 Normal mode
Normal mode is working state which including online mode and backup 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 ).
Online mode
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.
When all the communication lines are installed, push the waterproof cover into the
bottom, lock the screws fixed to the frame, and finally lock the waterproof cap.
5.5.11 Tighten the waterproof cover
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.
