1. Introduction
The access of Diesel Generator is in the off-grid scenario.
The system stores PV energy in batteries during daytime, provided that there is energy
surplus and supplies power to loads when the PV energy is insufficient or there is no PV
energy at night.
When the battery power drops to a certain value, and a power outage occurs in the grid,
the system will start the generator to power the load and charge the battery.
Generator’s work logic is as follows:
(i)when the grid is not available and the battery is discharged to GEN_Start_SOC, the
generator starts to power the load and charges the battery to GEN_Exit_SOC, then the
generator stops.
(ii)If the load power＞the generator rated power in (i), the battery will be discharged to
power the load until Overdischarge_SOC, then generator may shutdown due to
overload and the load will be powered off.
(iii)If the generator fail to start in (i), the battery will be discharge to Overdischarge_SOC,
then the load power off.
(iv)If the system goes into the end of (iii), the battery will not discharge before it is
charged to Overdischarge_SOC+ Overdischarge_Hysteresis_SOC (set by user).

NOTE:
In single system, a diesel generator can be connected via both AC-Gen port
and ATS. If via AC-Gen port, it will only supply power to the backup load ;
if it is necessary to supply power to the grid side, it is recommended that the
generator be connected through ATS.
In parallel-system scenarios, connecting a diesel generator via ATS is
recommended.
When the system is connected to the generator, it cannot be connected to a
grid-tied inverter, because of a risk of damaging the generator.
It is recommended that the generator power be greater than the backup load
power.
If the generator is connected through an ATS on the grid side, then CT or
smart meter is required.
CAUTION:
When the generator is connected, it is essential to correctly select the
generator position on the APP, otherwise it may cause system failure or
damage to the generator.

Third-party grid-tied inverter can be connected via AC-Gen port.
With third-party grid-tied inverter connected to the system, it is recommended that:
Grid-tied inverter power＜ rated AC power of S6 inverter.
In on-grid scenario, when the third-party grid-tied inverter is connected, the system
cannot control the output power of the third-party grid-tied inverter, so Feed-in limitation
cannot be realized.
In off-grid scenario, the third-party grid-tied inverter must be configured with the correct
grid code and equipped with over-frequency load shedding and under-frequency load
rising functionalities. These features allow the system to dynamically adjust the frequency,
effectively controlling the output power of the grid-tied inverter.
The Gen port has extended power, which can be used as Smart load output.
You can use the smartload function to connect critical loads to the backup port and
non-critical loads to the Gen port. This allows you to manage the power supply of
different loads when off-grid.
When the battery SOC/Volt reach the ON set value, the smart port will supply power to
the load. When the battery SOC/Volt drops to OFF SOC/Volt, it will cut off the power of
the load.

CAUTION:
If DC inputs are accidently reversely connected or inverter is faulty or not
working properly, it is NOT allowed to turn off the DC switch. Otherwise it
may cause DC arc and damage the inverter or even lead to a fire disaster.
The correct actions are:
*Use a clip-on ammeter to measure the DC string current.
*If it is above 0.5A, please wait for the solar irradiance reduces until the
current decreases to below 0.5A.
*Only after the current is below 0.5A, you are allowed to turn off the DC
switches and disconnect the PV strings.
* In order to completely eliminate the possibility of failure, please disconnect
the PV strings after turning off the DC switch to aviod secondary failures due
to continuous PV energy on the next day.
Please note that any damages due to wrong operations are not covered in
the device warranty.

If the system is set to not export any power, then the inverter will curtail
the PV power (derate the inverter output power).
PV power flow priority sequence: loads ＞ grid ＞ battery.
In this mode, the system exports any excess PV power after the loads
are supplied. If the export power quota has been met, then the remaining
PV power will be stored in the battery.
Notice: This mode should not be used if export power set to zero.

The battery section of the app offers numerous options to customize the interaction
between the inverter and the battery. Here, we provide explanations for the functions
and features available in this section, allowing users to tailor the inverter's behavior to
their specific preferences and requirements.
Battery Type: Please select the correct Type of the battery. Lead-acid battery and lithium
battery.
Battery Mode: Please select the correct model of the battery. If you don't have a battery,
choose "No battery" to ensure accurate configuration.
Max Charging/Discharching Current: Choose the maximum charge/discharge current
that you wish to. This selection allows you to customize the charging and discharging
parameters based on your preferences and requirements.
Overdischarge SOC: The Overdischarge SOC (State of Charge) is the minimum battery
charge level to which the inverter will discharge. It acts as a safeguard to prevent the
battery from discharging beyond this specified threshold, ensuring its longevity and health.
Recovery: The battery can discharge when the SOC/Voltage reaches the set value.
Forcecharge: The Forcecharge SOC for the battery is the minimum state of charge(SOC)
at which the inverter initiates charging the battery from the grid. It specifies the threshold
below which the inverter actively engages in recharging the battery to maintain optimal
performance.
Battery saving: Reduce battery loss. The necessary power for the operation of the inverter
preferentially obtains from the grid, not from the battery.
Max charge SOC: The maximum SOC/Voltage that the battery can be charged to.

The wake up current depends on the battery, up to 6A.
Battery Healing Switch: When the lithium battery maintains low power for a long time,
the battery SOC measurement is not accurate，It is necessary to charge the battery to
100 % from low power level to ensure the healthy and stable operation of the battery.
Working logic: PV+grid charge the battery from Forcecharge SOC to overdischarge SOC ,
then grid stops charging, PV gives priority to charging the battery to Battery Healing SOC.
And the battery does not discharge before reaching the set Battery Healing SOC.
Battery Peak shaving: In this function, the force charge power will be dynamically
adjusted and not exceed the set value minus the load power when force charging.

With an existing PV plant connected to the system, it is recommended that:
Grid-tied inverter power＜ rated AC power of S6 inverter.
In an on-grid scenario, when the third-party grid-connected inverter is connected, the
system cannot control the output power of the third-party grid-tied inverter, so feed-in
limitation cannot be achieved;
When connected in off-grid scenario, the third-party grid-tied inverter needs to set the
correct grid code, and has the function of over-frequency load shedding & under-frequency
load rising, so that the system can adjust the frequency to control the output power of the
grid-tied inverter.
When the system is connected to the generator, it cannot be connected to the grid-tied
inverter, as there’s a risk of damaging the generator.
A. Select the AC couple input.
B. Set the Max frequency according to the specification of the PV inverter.
The hybrid uses Freq-Watt to control the output of the PV inverter. Please consult with the
PV inverter’s manufacturer to confirm the correct setting procedures of its Freq-Watt

5.14 Only PV power load function
1. Function Definition
For PV generation is not stable, the default setting of S6 energy storage machine don’t
support only PV power the load.
But for meeting the some customers’ special requirements, we develop the Only PV Power
Load function, when the PV power > the load power, you can use this function.
Because the PV power is not stable and the load is also not always stable, it is possible to
happen that PV power < load power, when it occurred, the load will shut down and after 3
minutes, the inverter tries to restart the load for the first time, after 5 minutes, the second
time, and after 10 minutes, the third time. If the third attempt to restart the load is still not
successful, the inverter will not try to restart, and it needs to be manually reset and restarted.
NOTE:
1. Only PV Power Load function is closed by default. If you need to use it,
you need to open it by yourself.
2. Software: Ensure that the current DSP and HMI software is the latest

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 Mode 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.
Peak-shaving Mode: Peak-shaving function is possible to set the maximum power (Pmax)
that the system obtains from the main grid. The power of the main grid charges batteries and
supplies power to the load, which is within (Pmax). When the load power exceeds the set
maximum power (Pmax), the insufficient part is provided by the battery. At the same time,
users can set the Peak SOC and charge the battery to this SOC as far as possible under the
premise of satisfying Pmeter.
(Tips: Only the lithium battery with CAN connection support the peak-shaving mode)

AC Coupling Scheme
Customers can integrate a new energy storage inverter (S6 Hybrid) to an existed Grid - tied
inverter system. Users can select two ways of AC Coupling connection modes. One is connect
the Grid –tied inverter to S6 inverter Gen port and another is on the backup Port.
(Tips: When the total system is at on-grid status, the grid-tied PV inverter MUST be connected
to the backup port of hybrid inverter. )
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.

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=P_Grid(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 self-
consumption power, if not charged for a long time, the SOC will slowly continue to decline.)

User Manual
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.

Battery Discharge Hysteresis SOC
When the Force-charge SOC is reached, the battery will be force-charged to the Overdischarge
SOC + Overdischarge Hysteresis SOC. Overdischarge Hysteresis SOC range from 1% to 20%,
Overdischarge Hysteresis SOC default value is 1%.
For example: If customer set the Overdischarge SOC is 20%, Overdischarge Hysteresis SOC
is 5%.When the battery SOC is discharged to 10%( Forcecharge SOC set as 10%), Then the
lithium SOC will be forcecharged to 25%.
Battery Healing function
When the lithium battery is kept at low SOC for a long time, the measurement of lithium battery
SOC is not accurate. The Battery Healing function will allow the system to charge the battery to
the set Battery Healing SOC when the battery reaches the discharged SOC, so as to ensure the
healthy and stable operation of the lithium battery.
The Battery Equalization function of lead-acid battery
Pre-condition: When the days since last battery balancing exceed battery balancing Interval
days already set.Then the inverter will not enter the floating charge mode when the lead-acid
battery floating charge judgment is met for the first time on the same day when pre-condition
occur. But force charge battery at a balanced voltage on a constant voltage state, the charging
time is the time of balance, after finishing it, battery enter into float-charging state.

The Second backup load and smart load
Second backup load: The GEN port can be set as the second Backup port(The setting name
on App: Gen Port Load Open), The Gen port has extended power, which can be used as a
second Backup port to pick up loads when the generator is not connected, thus expanding
backup capacity. In addition, in off-grid mode, the customer can remotely control, shut down
this port, so that some non-essential loads stop running, while keeping the necessary loads,
to achieve the purpose of energy saving.
Smart load: The smart load function means there is a load connected to GEN port can start
or stop smartly. When the PV energy and battery SOC/Volt meet the set value, the relay at the
generator port closes and outputs energy. When the PV energy is less than the set value or the
battery SOC/Volt drops to OFF SOC/Volt, the relay disconnects and stops supplying power to
the smart load.
Example: Set Start_Power=500W, Smart Load_ON_SOC=100%, Smart Load_OFF _SOC=95%.
When PV≥500W and SOC reaches 100%, Gen port supplies power to smart Load. If PV < 500W
or SOC≤95%, the relay is disconnected and power supply is stopped.

Frequently Asked Questions
Q2: Why I have "BATName-Fail" Alarm on the inverter ?
A: Please check in the "Battery Setting->Battery Model" setting and confirm you selected the
correct battery option as the nameplate of your battery module.
Q3:Why I have "MET-SLT-Fail" Alarm on the inverter?
A: Please check in the "Meter Setting->Meter Type" setting and confirm you selected the
correct meter option corresponding to your smart meter.
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.
Q1: Why I have "CAN Fail" Alarm on the inverter?
A:"CAN Fail" indicates the CAN communication between inverter and battery is lost.
Please double check if your CAN cable is correctly connected and if your battery is power on.
Q5: Why I have "OV-ILLC" Alarm on the inverter ?
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.
Q6: Why I have "OV-BATT-H" Alarm on the inverter ?
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.
Q7: Why I have "No-Battery" Alarm on the inverter?
A: Please double check if the battery power cables have been correctly connected and the
battery breaker (on battery or external) has been turn on. If you don't want to connect the
battery for now, please select the "No battery" option in "Battery Setting->Battery Model"
to prevent the alarm to show up.
