When the inverter is powered on,the five indicators will be lighted at once.

5.3 Power OFF
Step 1: Turn off the AC breaker or AC disconnect switch to disable AC power to the inverter.
Step 2: Turn off the DC switch of the inverter.
Step 3: Turn off the battery breaker.
Step 4: Use a multimeter to verify that the battery and AC voltages are 0V.

5.4 Log in the APP via Bluetooth
Step 1: Connect with Bluetooth.
Turn on Bluetooth switch on your mobile phone and then open the Soliscloud APP.
Click “More Tools”->”Local Operation”->”Connect with Bluetooth”

Step 2: Select the Bluetooth signal from the inverter. (Bluetooth Name: Inverter SN)
Step 3: Login account.
If you are the installer, please select the account type as Installer. If you are the plant owner, please select the account type as owner. Then set your own initial password for control verification. (The first log-in must be finished by installer in order to do the initial set up)

5.5 Initial set up
If this is the first time the inverter has been commissioned, you will need to first go through the Quick Settings.Once this has been done,these settings can be changed later.
Inverter Time -> Battery Model -> Meter Setting -> Grid Code -> Work mode A. Inverter Time: Set the Inverter Time and Date. It may be easier to tap the slider next to “Follow Phone Time”.Then tap Next in the top right corner. This will set the inverter to
match your phone.

B. Battery Model: Now select the battery model connected to the inverter. This choice must be based on the battery model that is actually connected to the inverter. If there is no battery connected for the moment, select”No Battery”to avoid potential alarms codes.

C. Meter Setting: Set both the Meter Type and the Meter Location. It is suggested to install the meter at the system grid connection point and select “Meter in Grid”.If there is no meter connected for the moment, please select”No Meter” to avoid alarms.

D. Grid Code: Please select the grid code based on the local grid network requirements.

E. Work Mode: This is the energy storage operating mode. ALL modes first priority is to use the available PV power to support the home loads. The different modes determine what the second priority, or use of the excess PV power, will be. Select the desired mode,  then tap the slider switch to turn the mode on. The switch will appear orange if it is enabled.

Self-Use Mode stores the excess PV power into the battery. If the battery is charged, or there is no battery, the excess PV power will be exported(sold)back to the utility company. If the system is set to not export any power, then the inverter will curtail the PV power(derate the inverter output power).
Feed in Priority Mode will ensure that the system exports any excess PV power after the home loads are supplied. If the export power quota has been met, then the remaining PV power will be stored in the battery. This mode should not be used if export power is going to be set to zero.
Off-Grid Mode is only to be used by systems that are not electrically connected to the grid at all. This mode is like Self-Use Mode, but the PV power will be curtailed if the battery is charged and the home load demand is lower than the amount of available PV power.
Backup Mod e can be opened in the Self-Use or Feed in Priority Mode. What this mode does is ensure that the battery does not drain past the Reserve SOC (state-of-charge) percentage. The battery will cycle between 100% and the Reserve SOC, so if grid power is lost, the battery will have the Reserve SOC at the very least to carry the home through the outage.
Time of Use Switch is for customizing when the battery is allowed to charge and discharge power and at what rate, established by a current(amperage)setting.If this slider switch is turned on, the inverter will only use this schedule to determine when to charge and discharge the battery. If Allow Grid Charging is turned on, the inverter will use grid power to charge the battery only under two circumstances:(1) the battery drains to the Force Charge SOC. (2)Time of Use is enabled and there is not enough available PV power during the charge window to meet the current rate that is established.
Time of Use is for manual control of the battery charging/discharging.If Time of Use is turned off, charging/discharging is automatically regulated by the inverter.

GEN Information: generator power, today and total generator yield, and warning information.
Parallel Information : information includes inverter, battery, grid and load.
Battery: battery model and status, battery voltage and current.
Grid: power imported an exported, AC grid voltage, frequency, and amperage.
Load: power being consumed by the home loads and backup loads.

5.6.4 Alarm
The alarm page can display the current alarm and the historical alarm.

5.6.5 Settings
Mode Setting
The interface can display the current work mode, Self-Use/Feed in Priority /Off-Grid.
Please refer to page xxx for specific introduction.
Battery Setting
Battery Model: select the battery model to be connected.
Peak-shaving setting: If the switch is enable, the power of force charging will be dynamically adjusted.
Few samples to be clear: (Forcecharge Limited Power Setting=4kW)
If the load=3kW,PV=0kW,P_forcecharge=PGrid(4kW)-P Load(3kW)=1kW.
If the load=10kW,PV=0kW,P_forcecharge=0kW,P_Grid=P_Load=10kW.
ECO Function: If PV power is lower than 100W and SOC falls below overdischarge SOC, the inverter will turn off the grid relays and IGBT switching. If forcecharge SOC is reached, it will connect back to grid and charge battery back to overdischarge SOC, then turn off again.
Battery wake up : After Battery wake up command, the inverter powers the DC battery port using Battery Wakeup Voltage and low AMP till BMS communication of battery will be restored and within awaken time.
Over-discharge SOC: When the battery is discharged to the over-discharge soc, the battery will nor discharge actively.(Due to the internal current, conduction, there is a small selfconsumption power, if not charged for a long time, the SOC will slowly continue
to decline.)
Force-charge SOC: Due to the battery power consumption, when the over- discharge SOC drops to the force-charge SOC, the inverter will directly charge the battery according to the maximum battery charging current until the battery SOC reaches the over-discharge SOC. (The charging power is nor limited to sources, which may be from PV or from the grid. If “Charging from grid”is set to “Not Allow”,the charging logic may not be implemented.)
It is not recommended to set the over-discharge&force-charge SOC to the same value, which may cause frequent charging and discharging.

GEN_Start_SOC/Volt: If SOC/Volt reaches GEN_Start_SOC/Volt, the generator can be started.
GEN_Exit_SOC/Vot: If SOC/Volt reaches GEN_Exit_SOC/Volt, the generator can be stopped.

Meter/CT Setting
You can select meter or CT for system measurement.
Meter Type : Please select a correct type. The wrong option may cause the meter RS485 communication Failed. If the battery and meter are not connected, please select the “NO Meter” to shield the alarm of meter communication fault.
CT Reverse: If the direction is wrong, the sampling current of CT will be reversed when calculating the power.
CT Ratio: CT ratio is adjustable.

Grid Power Setting
System Export Power/Current: This is the amount of power/current the inverter is permitted to export(or sell) back to the utility company. If you do not want the system exporting power, this setting must be configured.
Failsafe Switch: Enabling the Failsafe switch will mean that the inverter will not produce any P power if the inverter loses communication with the meter.

Backup Setting
Backup Voltage Setting: This is the voltage designated to the backup loads in the event of a grid power loss.

Generator Setting
With Generator : Please turn it on if the generator is ready to work.
GEN Power Setting: GEN Rated Power/GEN Max.Charge Power.
Generator Position: Grid Port/GEN Port.
Grid Port Powered By: If the generator is connected in Grid Port and the generator works , please select “Generator”.
GEN Signal: If the generator can automatic start-stop,turn on the switch, once the generator start condition is reached,the inverter will start the generator automatically.
GEN Force: If GEN_Start_SOC<SOC<GEN_Exit_SOC/GEN_Start_Volt<Volt<GEN_Exit_Volt, the generator can be forced to start.
GEN Stop: If GEN_Start_SOC<SOC<GEN_Exit_SOC/GEN_Start_Volt<Volt<GEN_Exit_Volt, the generator can be forced to stop.

Parallel Setting
Parallel Mode: Single/Parallel
Address ID: 1 to 6
Manual Set Master/Slave: Address ID 1 is Master, the others is Slave.
Inverter Connected Phase Setting: Single Phase(single phase system)/ Phase A(Three Phase)/Phase B(Three Phase)/Phase C(Three Phase)
Total number of hybrid inverters connected: 0-6
Parallel Sync: The parameters of the master will be synchronized to the slaves, and some parameters of the slave cannot be set.

The inverter commissioning process has now been completed. It is recommended to monitor the system closely over the next week to ensure that everything is working as it should. Please refer to the Solis data logger manual for assistance with registering a new plant on SolisCloud.

NOTE:
A full factory reset can be done, if needed. This function can be found in the Special Setting Function menu within the Settings tab.

Solis S6 Series inverter does not require any regular maintenance. However, cleaning the heatsink will help the inverter dissipate heat and increase the lifetime of inverter. The dirt on the inverter can be cleaned with a soft brush.
CAUTION:
Do not touch the surface when the inverter is operating. Some parts may be hot and could cause burns. Turn OFF the inverter and let it cool down before you do any maintenance or cleaning of inverter.

The Screen and the LED status indicator lights can be cleaned with cloth if they are too dirty to be read.

Frequently Asked Questions

Q4:Why the power values on the screen are fluctuating very fast?

A: If your loads are changing drastically, the inverter will adjust its power accordingly. If you confirm the loads are stable while the inverter power is changing very fast, please double check your meter CT's direction and make sure the arrow is towards grid.

A: OV-ILLC indicates there is an overcurrent issue on the internal LLC circuit. It could be transient status during extreme condition such as overload. If it happens constantly or too frequent and the extreme conditions have been excluded, please contact Solis service team.

A: OV-BATT-H indicates over voltage issue on the hardware of battery circuit. It could be caused by high battery voltage at full SOC, battery suddenly switching off, etc. If it happens constantly or too frequent and the extreme conditions have been excluded, please contact Solis service team.
