6 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 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.
Online mode
User can set an appropriate priority mode according to request when SPH working on the online mode. If customer
uses 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.
Users can set power rate which less than the battery maximum output power. If the customer doesn’t enable the
AC CHG (AC grid charging functions). Inverter will charge battery by PV power as large as it can do. If the customer
enables the AC CHG (AC grid charging functions). 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.
