Introduction

The inverter is a hybrid or bidirectional solar inverter, suitable for solar systems involving PV, batteries, loads, and grid systems for energy management. Inverter should not be applicable to multiple phase combinations. The energy generated by the photovoltaic system can be used to optimize household electricity consumption; the excess energy is used to charge the battery, and the remaining energy is exported to the grid. When the photovoltaic energy is not enough to meet the self-use demand, the battery should be discharged to support the load. If the battery is low, the load will be powered by the grid.

Battery Protection
Battery charging and discharging are limited to protect the battery in the following cases: ·Battery SOC is lower than -DOD (Depth of Discharge). ·The battery voltage is lower than the discharge voltage. ·Battery overheating protection is activated. ·Abnormal communication with the lithium battery. ·Lithium battery BMS limit is reached.
When the current limit protection occurs:
·Under on-grid mode, battery charging and discharging operations may be abnormal. ·Under off-grid mode, the inverter will not supply power to the backup terminal.
Note: ·Off-grid cut-off SOC is %. Batteries discharged to % under off-grid conditions cannot be further
discharged. They must be charged to a level of %, at which point only charging is allowed. Once the battery SOC exceeds %, the batteries can be discharged again.
·On-grid cut-off SOC is %. In grid-connected conditions, when the battery is discharged to %, it must be charged back to %, at which point only charging is allowed. Once the battery SOC exceeds %, the batteries can be discharged again.
·Setting the battery DOD prevents the battery from being fully drained. Once the DOD set point is reached, the load will only be powered by the PV or grid. If the battery has received little or no charge for several days, it may continue to drain to maintain communication with the inverter. Batteries from different manufacturers have different behaviours, but if the SOC of the battery reaches a certain level, the inverter will charge the battery slightly to maintain the SOC. This protection mechanism prevents the battery SOC from dropping to %.

The Inverter Side

Declarations for The Back-up Function
The backup output of the hybrid inverters has overload capability. The inverter also has self-protection derating at high ambient temperatures.
. For standard photovoltaic installations of the energy storage inverters, it is usually necessary to connect the inverter to photovoltaic panels and batteries. Any consequences resulting from non-compliance with this requirement are excluded from the manufacturer’s warranty and liability.
. In general, the off-grid switching time is less than ms (considering the minimum conditions of EPS). However, external factors may prevent the system from starting off-grid mode. Therefore, we recommend users to be fully informed and follow the instructions below:
· Do not use this function if the load requires a stable power supply for reliable operation. · Do not connect loads that may exceed the maximum off- grid capacity. · Avoid loads that may generate high starting current surges, such as high-power pumps. · The battery current may be limited by factors including, but not limited to, temperature and weather
conditions.

Acceptable Loads
The back-up side of the K inverter can provide a continuous output of VA for the load. The inverter also includes a self-protection mechanism that derates output at high ambient temperatures. ·Inductive Load: Maximum KVA for single inductive load, maximum .KVA for total inductive load power. ·Capacitive Load: Maximum .KVA for total power of capacitive loads (e.g. computers, switching power
supplies, etc.). (Do not connect any load with high inrush current at startup)
Note: To facilitate maintenance, use an SPT switch on both the off-grid and on-grid sides. After installing the SPT switch, the load power supply mode can be changed by adjusting the circuit breaker switch. The options include maintaining the default state, grid power supply, and off-grid power supply.

. Settings
The following settings with ” ” can only be viewed but not changed. If you need to change them, please contact your installer or HINEN. * The following is an example of a user version that can only read view fields/commands. The user will not be able to click on any of the locked fields / commands after the system has been commissioned.

.. Common Settings
Click “Device” to enter the following interface, click “Remote Control”.

Remote Power Control
You can find the “Remote Power Control” function in the “Batch Commands”, which is a setting to control fast charging and discharging.
·Setting fast charging and discharging enable: Enable/Disable for Enable Setting, Disable Setting.
· Setting fast charging and discharging time: from “:” to “:”, which means that it can only be charged and discharged in the set time.
Note: under normal circumstances, the battery stops charging when it is charged to %, and stops discharging when it is discharged to %. The start and stop SOC of the battery when it is charging or discharging can be set using “Load First Settings”.
· Setting fast charging and discharging power: the range is from “- to ” %, from “- to ” % fordischarge power, from ” to ” % for charging power.
·In the charge and discharge setting, if the set time is “:”, that is, charge and discharge all the time, without limiting the time, stop charging when the power reaches %, and stop discharging when the power reaches %. The start and stop SOC of the battery when it is charging or discharging can be set using “Load First Settings”. If the inverter is suddenly disconnected, that is, the grid and the battery are all disconnected, the set charge/discharge settings will become invalid.
·After the Settings are completed, you need to click the “Setup” button to send instructions.

Period Time
There are priority periods in the APP, and each period has three setting options
·Period N Start time: The value ranges from : to :.
·Period N End time: The value ranges from : to :.
·Period N charge and discharge power rate: The range from “- to ” %. When a negative value between – and is set, it indicates that the system is discharging at that power; when a positive value between and is set, it indicates that the system is charging at that power.
·Period N stop SOC : The cut-off SOC for charging and discharging.
. If you set multiple priority periods, the number of effective depends on the set “number of priority periods”. . At the same time, in the effective priority period, not in accordance with the set priority period serial number < such as from – to run in sequence >, but in accordance with the set time period to charge and discharge.

Open Settings
Charge time is hours
Charge at % charging power

Open Settings
If you do not set a specific time, the default is always
charge and discharge, here is always discharge
Discharge at % power

Note: If you set fast charge and discharge, the priority period will be invalid. The priority of the fast charge and discharge setting is higher than that of the later priority period setting.When the preset period of fast charge and discharge coincides with a preset priority period, the preset period of fast charge and discharge is activated preferentially.

Start charging at :
Stop charging at :
Charge at % charging power
Charging cut-off SOC is %

Start discharging at :
Stop discharging at :
Discharge at % discharge power
Disharging cut-off SOC is %

Note: After setting the priority period, you need to set the number of charge and discharge periods immediately to activate the preset priority period. At the same timeyou cannot set two overlapping periods. For example,if you set the time ranges from : to : and from : to :, and the time ranges from : to : coincide with each other, you need to set the priority time ranges from : to : and from : to :. When the inverter suddenly loses power, that is,when the grid and battery are all disconnected, the set prioritry periods are automatically saved.

Number Time Periods
After setting all the charging and discharging periods, we can set the”Number Time periods”to activate the set charging and discharging periods. For example, a total of charge and discharge periods are set, but the number “” is entered in “Number Time Periods”, then the first two of the priority periods are activated. Generally, priority periods are set from period in numerical order (For example, period , period , period …). The charging and discharging periods is also activated in sequence (For example, time period , time period , time period , time period , time period is set, but the charging and discharging period is set to , then the time period and are activated) After the setup is complete, you need to click the “Send Command” button to activate the instruction.
Entering “” indicates that the first six periods are activated

Prioritization Mode
In the actual use of the inverter, it usually involves the setting of the priority level, and there are generally three priority setting methods: “Load Priority”, “Battery Priority” and “Grid Priority”.
Types Of Prioritization Models
·Load Priority Mode: The inverter system is turned on to prioritize power to the loads, which can draw power from the grid, PV, or batteries. If the”Period Time”setting is not enabled, the system defaults to Load Priority Mode.
·Battery Priority Mode: Excess power exists after the inverter system is turned on to satisfy the load, charging the battery is prioritized. In the “Period Time” setting, if the charging power is between % and %, the system is set to Battery Priority Mode.
·Grid Priority Mode: Excess electricity that exists after the inverter system is turned on to satisfy the load is prioritized to be discharged to the grid. In the “Period Time” setting, if the discharged power is between -% and %, the system is set to Grid Priority Mode.
View Priority Mode Status Click on the inverter you want to view, then click on the “Device Parameters” button and locate “Control” in this screen to display the relevant priority information.

NOTE: When the”Number Time Periods”is entered as””and activated, the preset priority periods will be cleared and need to be reset.

Set ON/OFF Enable
This is the device start switch. After plugging in the device, the device will enter standby mode and the device will run when the switch is turned on. Click “Single Command” “Select Command” “Command Name” select “Set ON/OFF Enable” function , click “Confirm”, and click “On/Off” to open or close the inverter. After the setup is complete, you need to click the “Send Command” button to activate the instruction.
CT Mode
Please select METER/CT Mode according to the actual condition of your equipment.
NOTE: While installing CT, paying special attention to the direction. After opening the ring buckle of CT, there will be an arrow, and the CT will be connected to the live line of the power grid interface of the inverter, and the arrow points in the direction that should follow the current, and then the CT will be connected to the end of the CT to the “METER” of the inverter.

Anti-Backflow
The main function of the anti-reverse current is to limit the current output from the inverter to the grid and thus limit the power output from the inverter to the grid. In some situations , this function is also referred to as Export limitation or Zero export. The anti-reverse current function is a soft limit. When the output power exceeds the soft limit value, the inverter output power is reduced such that the export limit is reached within seconds.

• The inverter has generation control function , which monitors the response of the inverter combination to soft limit and hard limit. But this feature is monitored internally by Hinen’s software team. Note: To use this function, please connect a smart meter or CT. In the Batch Command, Anti-Reverse Current function is divided intosuch as “Read/Set Local Anti-Backflow Enable”, “Read/Set Backflow Meter Power Limit”, and “Read/Set backflow Fault Power Rate”.
  ·Anti-Backflow Enabl: select”Anti Backflow Enable”to limiting the power supplied by the whole system to the power grid. If your equipment is a three- phase inverter, you can select”Three-phase Independent Back Prevention Enable”.

·Anti-Backflow Limit Rate It is mainly to control the grid-connected power of the whole system. “%” means that the whole system does not supply power to the grid, and “%” means that the whole system supplies power to the grid with the maximum power.
After turning on the anti-backflow enable switch, we need to input %-% to limit the grid-connected power. Taking the kw single-phase inverter as an example, inputting % means that the grid-connected power of the whole system is W.
·Anti-Backflow Fail Rate: In the event of a meter failure or damage that causes the anti-backflow function fail, this setting can control the output power of the entire system (including the on-grid and off-grid ends).
The range can be set from -%. Take a KW single-phase inverter as an example, setting % means that the output power of the entire inverter is .KW, which can be used when the meter fails.

·Anti-Backflow Fail time If the meter is faulty or damaged, the anti-backflow function will fail. However, the anti-backflow failure time can be set in advance to make the device automatically start the anti-backflow function after the meter failure. For example, set the S failure time, that is, from the moment the meter fails, after S, the device will automatically turn on the anti-backflow function.
NOTE: set “Anti-Backflow Fail time” and “Anti-Backflow Fail Rate” only after the anti-backflow current function is enabled.

Checks At Startup and Turning On AC Power
Battery Settings, BMS Communication and On Line LimitOff Grid Settings. After connecting the data collector, check the APP”Battery Type” to make sure that the battery type is the same as was installed. Also check that the “On Line Limit” setting and “Off Grid Settings” setting are correct. If it is not correct, please set it correctly in “Setup”.
Note: For compatible lithium batteries, the BMS status will display “Normal” after selecting the correct battery company.

Problems During Operation
. The inverter did not start up with PV only. () Make sure the PV voltage is greater than V. () Make sure that, for the connection between the inverter and PV panels, the polarities (+/-) are not
reversed.
. Hybrid inverter does not discharge or output when off-grid or no PV or PV power is less than the load power. () Check whether the communications between the inverter and Smart Meter are OK. () Make sure the load power is greater than W.
a. The battery will not discharge continuously unless the load power is greater than W. b. If the battery does not discharge when the Meter power is greater than W, please check the
Smart Meter & CT connections and directions.
() Ensure that SOC (discharge status) is greater than -DOD (discharge depth). Alternatively, if the battery discharges below -DOD, the battery will only discharge again when the SOC is charged to a level greater than (%+-DOD/).
() Check on the APP whether the charge time has already been set because during the charge time, the battery will not discharge (battery will charge in priority during times of concurrent charge/discharge).
. The battery does not charge when the PV power is greater than the load power. () Check if charge voltage on APP (in “Battery Type”) is properly set (for lead-acid battery), as battery cannot charge if battery voltage reaches charge voltage. () Check the discharge time setting on APP. () Check if battery is fully charged or not, or if battery voltage reaches “charge voltage” or not.
. High power fluctuations during battery charge or discharge. () Check if there are fluctuations in load power. () Check if there are fluctuations in PV power.
. Battery does not charge. () Make sure that BMS communications are OK on the APP. () Check if the CT is connected at the right position and is connected in the right direction per the User Manual. () Check if the total load power is significantly higher than the PV power.

Questions & Answers (Q & A)
About the WIFI Configuration
. Why can’t I find the WIFI signal on mobile devices? Normally the WIFI signal can be seen immediately after inverter has powered up. However, the WIFI signal will disappear when the inverter connects to the internet. If settings need to be changed, please connect the router. If you cannot find the WIFI signal or connect to the router, please try to reload the WIFI.
. Why can’t I connect to the WIFI signal on my phone? The WIFI module can only connect to one device at a time. If the signal is already connected to another device, you will not be able to connect to the signal.
. Why does the WIFI module fail to connect to network after I choose the right router hotspot and enter the right passwords?
It’s possible that there are special characters not supported by module in the hotspot passwords. Please modify the password to consist of only Arabic numerals or uppercase / lowercase letters.
About Battery Operation . Why does the battery not discharge when the grid is not available but it discharges normally when the grid is available?
On the APP, the off-grid output and backup function should be turned on to force the battery to discharge under off-grid mode. . Why is there no output on the backup side? For backup supply, “Backup Supply” on the APP must be turned on. In off-grid mode or when the grid power is disconnected, the “Off- Grid Output Switch” function must be turned on as well.
Note: When turning the “Off-Grid Output Switch” on, do not restart the inverter or battery. Otherwise, the function will be switched off automatically.
. Why does the battery SOC suddenly jump to %? This normally happens when BMS communications fail when using lithium batteries. If the batteries enter float charge mode, the SOC is automatically reset to %.
. The battery cannot be fully charged to %? The battery will stop charging when the battery voltage reaches the charge voltage set in the APP.
About APP Operation And Monitoring
. Why can’t I save settings on the APP? This could be caused by losing the connection to WIFI.
· Make sure you have already connected to WIFI (make sure that no other devices are connected) or to the router (if WIFI is connected to the router). The APP homepage shows the connections.
· Make sure you restart the inverter mins after you have changed any settings because the inverter will save the settings every mins while operating in normal mode. We recommend that parameter settings be changed when the inverter is in wait mode.

. Why are the data displayed on the homepage different from the param page, like charge/ discharge, PV value, load value, or grid value?
The data refresh frequency is different, so there will be data discrepancies between different pages on the APP as well as between these shown on the portal and APP. . Some columns show NA, like battery SOH, etc. Why does that happen? NA means that the APP has not received data from the inverter or server because of communication problems, such as battery communications and the communications between inverter and the APP.
About the CT and Power Limit Function
. How to activate the output power limit function? This function can be activated by following these steps: · Make sure the Smart Meter/CT connections and communications are functioning correctly. · Enable the anti-reverse current function on the APP, and set the maximum allowable reverse current power to the grid on the APP.
Note: Even if the output power limit is set to W, there might still be a deviation of a maximum of W when exporting to the grid.
. Why is there still power exporting to the grid after I have set the power limit to W? The export limit could theoretically be W but there will be a deviation of around W.
. Can I use other meter brands to take over from the Smart Meter in the system or to change settings in Smart Meter?
No, because the communication protocol is integrated into the inverter and Smart Meter, other meter brands cannot communicate. Also, any change to the manual settings could cause a meter communication failure. . What is the maximum current allowed to pass through the CT ? The maximum current for the CT is A.
Other Questions
. Is there a quick way to make the system work? Please refer to this user manual.
. What kind of load can I use to connect to the backup side? It can be connected to critical loads in the home, such as refrigerators, computers, lights, etc. Please note that the load power cannot exceed the specification.
. Will the warranty of the inverter still be valid if, for some special conditions, we cannot follow % of the User Manual instructions for installation or operation?
Normally we still provide technical support for problems caused by not following the instructions in the User Manual. However we cannot guarantee any replacements or returns. So, if there are any special conditions for which you cannot follow the instructions %, please contact the after-sales department for suggestions.

The following error messages can be viewed through APP when a failure occurs.

Error Message

Explanation

Reason

Solution

Grid Loss

Public grid power is not available (power lost or on-grid connection fails)

Inverter does not detect the connection of grid

. Check (use multi-meter) if AC side has voltage. Make sure grid power is available. . Make sure AC cables are connected tightly and well. . If all is well, please try to turn off AC breaker and turn on again in mins.

VAC Failure

Grid voltage is not within permissible range

Inverter detects that AC voltage is beyond the normal range requiredby the safety country

. Make sure safety country of the inverter is set right. . Check (use multi- meter) if the AC voltage (Between L & N) is within a normal range (also on AC breaker side)
a. If the AC voltage is high, then make sure the AC cable complies with that required on user manual and the AC cable is not too long. b. If the voltage is low, make sure the AC cable is connected well and the jacket of the AC cable is not compressed into the AC terminal.
. Make sure the grid voltage of your area is stable and within normal range.

FAC Failure

Grid frequency is not within permissible range

Inverter detects that the grid frequency is beyond the normal range required by the safety requirement

. Make sure the safety country of the inverter is set right. . If safety country is right, then please check on the inverter display if AC frequency (Fac) is within a normal range. . If FAC failure only appears a few times and is resolved soon, it should be caused by occasional grid frequency unstability.

Over Temperature

Temperature inside of the inverter is too high

The inverter’s working temperature is too high.

. Try to decrease surrounding temperature. . Make sure the installation complies with the instruction on inverter user manual. . Try to close the inverter for mins, then start up again.

Error Message

Explanation

Reason

Solution

Isolation Failure

Isolation failure could be caused by multiple reasons like that the PV panels are not grounded well, DC cable is broken, PV panels are aged or surrounding humidity is comparatively heavy, etc.

Isolation failure could be caused by multiple reasons like that the PV panels are not grounded well, DC cable is broken, PV panels are aged or surrounding humidity is comparatively heavy, etc.

. Use multi-meter to check if the resistance between earth & inverter frame is close to zero. If it’s not, please ensure that the connection is well. . If the humidity is too high, isolation failure may occur. . Check the resistance between PV+/PV+/V+/PV/+BAT+/PV- to earth. If theresistance is lower than the minimum isolation resistance shown in the table( chapter .. ) , check the system wiring connection. . Try to restart the inverter. Check if the fault still occurs. If not, it means it is caused by an occasional situation, or contact after-sales.

Ground Failure

Ground leakage current is too high

Ground failure could be caused by multiple reasons like that the neutral cable on the AC side is not connected well or the surrounding humidity is comparatively heavy, etc.

Check (use multi-meter) if there is voltage (normally should be close to V) between earth & inverter frame. If there is a voltage, it means the neutral & ground cables are not connected well on the AC side. If it happens only in the early morning/ dawn /rainy days with higher air humidity and is recovered soon, it should be normal.

DC Bus High

BUS voltage is over-high
