6.1 Commissioning of SPH
Electrify SPH after all installation of Part5 be finished, here are the steps:
Ø
Connect PV
Ø
Connect AC
Ø
Connect battery
Ø
Turn on AC first
Ø
Then turn on battery
Ø
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:
Ø
Make sure all the connection is correct.
Ø
All the external switches are on.
Ø
Inverter built -in switch is on.
Ø
Make sure the lithium battery is on.
Ø
Refer to Part 9.1 for correction.
You can refer to Part 6.3.4 for work mode setting, then configure monitor, finish
commissioning.
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 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)
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 ).
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.
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.
Online mode
Backup mode
If Grid lost, system would turn to backup mode (user can disable it, refer to 6.3.4) and AC
output from EPS LOAD port, all the energy from PV and battery, if the PV also lost, then
only battery discharge. Mind you, SPH maximum output power is 6000W in this mode,
the load which connect with EPS LOAD should less than 6000W.
NOTICE:
User only can set one period for battery first and Grid first on the LCD, if user need set
more pleases login shineserver.
If user needs Grid charge battery, user need input password on the SC surface and set the
AC CHG to enable.
6.2.2 Fault mode
The SPH's intelligent control system could monitor and adjustment system's status
continuously, when SPH inverter monitoring anything unexpected happen, such as
system fault or machine fault ,the LCD will display the fault information, in fault mode,
the LED light will be lighten.
NOTICE:
Ø
The detail's fault information please refer to 9.1
Ø
Some fault information is in order to remind users that might have some faults
occurred in inverter side.
6.2.3 Programming mode
Programming mode indicates the SPH is updating, don't cut out power when it's
updating until the processing is finish, SPH inverter would log out automatically when
the updating finish and turn to other mode.
6.2.4 Checking mode
Before SPH work in normal mode, it will go to self-check mode. If all are ok, system will
go to normal mode, otherwise, it will go to fault mode.
6.2.5 Standby mode
If the system hasn't faults while the condition is not qualified, SPH would stay at standby
mode.
