6.1 Commissioning of SPA
6.2 Operation modes
6.2.1 Normal mode
1)Electrify SPA series after all installation of Part5 be finished,here are the steps
：
Turn on AC first
•Then turn on battery
•If Grid and battery are available, the SPA would work on the “normal”mode. When the
SPA work under the normal mode ,the screen showing “normal ”and the LED is green.
2)If SPA do not enter normal mode successfully, especially the LCD is red
，
you need to
check below
：
•Make sure all the connection is correct.
•All the external switches are on.
•Make sure the lithium battery is on.
•Refer to Part 9.1 for correction.
You can refer to 6.4.4 for work mode setting, then configure monitor,finish commissio-
ing lastly.
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 SPA 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. Please refer to 6.4.4 for
details.
Load first:
Load first is the default mode.
•
optimize load, then charge battery,
exceed power export to the grid.
With inverter, energy from inverter
•
inverter is weak, the battery will discharge
for load firstly and the grid will supply the
power when the battery power is not
enough.
Without inverter or the energy from
Battery First:
When SPA series working under 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.
•
charge battery, then load and the grid
will supply the power when the inverter
power is not enough.
With inverter, energy from inverter
•
inverter is weak, the grid will charge
the battery and load.
Without inverter or the energy from
Grid first:
When SPA series working under Grid-first mode, the battery 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.
•
load. If the sum of inverter power
and battery power is greater than the
load, excess power flows to the grid.
With inverter, battery discharge to
•
inverter is weak, battery discharge to
load and excess power flows to the grid.
