01 Introduction

The ES series, also called hybird or bidirectional solar inverters, apply to soalr system with partcipation of PV, battery, loads and grid system for energy management. The energy produced by PV system shall be used to optimize household, excess power charges battery and the rest power could be exported to the grid. Testing to AS/NZS 4777.2:2020 for multiple phase combinations has not been conducted

The battery shall discharge to support loads when PV power is insucient to meet selfconsumption needs. If battery power is not sucient, the system will take power from the utility

grid to support loads.

The preceding introduction describes the general operation

of the ES system. The operation mode can be changed

with the PV Master app based on the system layout. The

possible operation modes for the ES system are shown

below.

1.1 Operation Modes Introduction

ES system normally has the following operation modes based on your conguration and layout

conditions.

Mode I

The energy produced by the PV system is used to optimize self-consumption needs. The excess energy is used to recharge the batteries, any remaining excess is then exported to the grid.

Mode III

When the grid fails, the system will automatically switch to back-up mode. The back-up loads can be supplied by both PV and battery energy.

Mode II

When there is no PV, and the battery is

sucient, it can supply the load together

with grid power.

Mode IV

Battery could be charged by grid, and charge time/power could be set to various options on the PV Master App.

Safety Warnings

Any installation or operations on the inverter must be performed by qualied electricians

in compliance with standards, wiring rules and the requirements of local grid authorities or companies (such as AS 4777 and AS/NZS 3000 in Australia).

Before any wiring connection or electrical operation on inverter, all battery and AC power must be disconnected from inverter for at least 5 minutes to make sure inverter is totally isolated to avoid electric shock.

The temperature of inverter surface might exceed 60℃ during operation, so please make

sure it has cooled down before touching it, and make sure the inverter is out of reach of children.

Do not open the inverter's cover or change any components without manufacturer's authorization, otherwise the warranty commitment for the inverter will be invalid.

Usage and operation of the inverter must follow instructions in this user manual, otherwise the protection design might be impared and warranty commitment for the inverter will be invalid.

Appropriate methods must be adopted to protect inverter from static damage. Any damage caused by static is not warranted by manufacturer.

PV negative (PV-) and battery negative (BAT-) on inverter side is not grounded as default design. Connecting PV- to EARTH are strictly forbidden.

PV modules used on the inverter must have an IEC61730 class A rating, and the total opencircuit voltage of PV string/array is lower than the maximum rated DC input voltage of the inverter. Any damage caused by PV over-voltage is beyond warranty.

The inverter, with built-in RCMU, will exclude possibility of DC residual current to 6mA, thus in the system an external RCD (type A) can be used(≥30mA).

In Australia, the inverter internal switching does not maintain neutral integrity, which must be addressed by external connection arrangements like in the system connection diagram for Australia.

In Australia, output of back-up side in switchbox should be labeled on "Main Switch UPS Supply".The output of normal load side in switch box should be labeled "Main Switch Inverter Supply".

Battery Protection

Battery will act as a protective charge/discharge current limitation under any condition as below:

• Battery SOC is lower than I-DOD (Depth of discharge).

Page 15

User Manual V1.1-2022-01-05 02 Installation Instructions

• Battery voltage is lower than discharge voltage.

• Battery over heating protection.

• Battery communication is abnormal for lithium battery.

• BMS limitation for lithium battery. When charge/discharge current limitation protection happens:

• Under on-grid mode, battery charge/discharge operation could be abnormal.

• Under o-grid mode, Back-Up supply will shut down.

Note:

• Under o-grid mode, if Back-Up supply shuts o because of battery, low battery SOC or voltage, PV power will all be used to charge battery till battery SOC reaches 40% +(1-DOD)/2, then Back-Up supply

will be activated.

• Under on-grid mode & o-grid mode, battery is protected from over discharge by DOD and discharge

voltage.

• The DOD setting of a battery prevents the inverter from discharging battery reserve power. As soon as the DOD is reached the load of building will only be supported by either PV power or the grid. If

there are continuous days when little or no battery charging occurs, the battery may continue to self-

consume energy to support communications with the inverter. This behavior is dierent between battery manufactures products, however, if the SOC of the battery reaches a certain level, the inverter will boost the SOC back up. This protection mechanism safeguards the battery from falling to 0% SOC.

2.4.4 On-Grid&Back-up Connection

An external AC breaker is needed for on-grid connection to isolate the inverter from the utility grid when necessary.

The requirements for the on-grid AC breaker are shown below.

Inverter Model AC Breaker Specication

GW3648D-ES 32A / 230V (e.g. DZ47-60 C32)

GW5048D-ES 40A / 230V (e.g. DZ47-60 C40)

Note: The absence of AC breaker will lead to inverter damage if an electrical short circuit happens on grid side.

1. Use separate AC breakers for individual inverters.

2. On the AC side, an individual breaker should be connected between the inverter and grid but before any loads.

Declarations For The Backup Function

The back-up output of ES hybrid inverters have over load ability. For details please refer to the technical parameters of ES series inverter section (Page 31). And the inverter has self-protection derating at high ambient temperature. The below statement lays out general policies governing the energy storage inverters of the series EH, EM, ES, ET, BH, BT and SBP.

1. For Hybrid inverters (Series EH, EM, ES and ET), the standard PV installation typically consists of the connection of the inverter with both panels and batteries. In the case where the system is not connected to the batteries, the back-up function is strongly not advised for use. Manufacturer shall not cover the standard warranty and be liable for any consequences arising from users not following this instruction.

2. Under normal circumstances, the back-up switching time is less than 10 ms (the minimal condition to be considered as the UPS level). However, some external factors may cause the system failing on back-up mode. As such, we recommend the users to be aware of conditions and follow the instructions as below:

• Do not connect loads when they are dependent on a stable energy supply for a reliable operation.

• Do not connect the loads which may in total exceed the maximum back-up capacity.

• Try to avoid those loads which may create very high start-up current surges such as inverter air-conditioner, high-power pump etc.

• Due to the condition of the battery itself, battery current might be limited by some factors including but not limited to the temperature, weather etc.

Acceptable Loads Are As Below:

ES series inverter is able to supply a continuous 4600VA output or maintain a 6900VA output for less than 10 seconds on back-up side to support loads. The inverter also has self-protection against derating at high ambient temperature.

• Inductive Load: Maximum 1.5KVA for single inductive load, maximum 2.5KVA for total inductive load power.

• Capacitive Load: Total capacitive load (like computer, switch power etc.)power ≤3.0KVA. (Any load with high inrush current at start-up is not accepted)

Problems During Operation

The inverter does not start up with battery only Solution:

Make sure that the battery voltage is greater than 48V. Otherwise, the battery cannot start the inverter.

The inverter did not start up with PV only Solution:

1. Make sure the PV voltage is greater than 125V.

2. Make sure that, for the connection between the inverter and PV panels, the polarities are (+/-) not reversed.

The hybrid inverter does not discharge or output without the PV or when the PV power is less than the load power Solution:

1. Check whether the communications between the inverter and Smart Meter are OK.

2. Make sure the load power is greater than 150W. a. The battery will not discharge continuously unless the load power is greater than 150W. b. If the battery does not discharge when the Meter power is greater than 150W, please check the Smart Meter & CT connections and directions.

3. Make sure the SOC (State of discharge) is greater than 1-DOD (Depth of discharge). Or, if the battery is discharged to below 1-DOD, the battery will only discharge again when SOC is charged to (20%+1-DOD/2 (if battery discharge is needed immediately, the user should restart the battery).

4. 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 Solution:

1. Check if charge voltage on App(in "param")is properly set(for lead-acid battery), as battery cannot charge if battery voltage reaches charge voltage.

2. Check the discharge time setting on App.

3. Check if battery is fully charged or not, or if battery voltage reaches "charge voltage" or not.

Questions & Answers (Q & A)

About the Wi-Fi Conguration

Q: Why can't I nd the Solar-Wi-Fi* signal on mobile devices?

A: Normally the Solar-Wi-Fi* signal can be seen immediately after inverter has powered up. However, the Solar-Wi-Fi signal will disappear when the inverter connects to the internet. If

changes to the settings are required to connect to the router for changes. If you cannot nd the

Wi-Fi signal or connect to the router, please try to reload the Wi-Fi.

Q: Why can't I connect to the Solar-Wi-Fi* signal on my phone?

A: The Wi-Fi module can only connect to one device at a time. If the signal is already connected to another device at the same time, you will not be able to connect to the signal.

Q: Why does the Wi-Fi module fail to connect to network after I choose the right router hotspot

and enter the right passwords?

A: 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

Q: Why does the battery not discharge when the grid is not available but it discharges normally

when the grid is available? A: On the APP, the o-grid output and backup function should be turned on to force the battery

to discharge under o-grid mode.

Q: Why is there no output on the backup side? A: For backup supply, "Backup Supply" on the PV Master App must be turned on. In o-grid mode or when the grid power is disconnected, the "O-Grid Output Switch" function must be

turned on as well.

Note: When turning the "O-Grid Output Switch" on, do not restart the inverter or battery. Otherwise, the function will be switched o automatically.

Q: Why does the battery SOC suddenly jump to 95% on the Portal?

A: This normally happens when BMS communications fail when using lithium batteries. If the

batteries enter oat charge mode, the SOC is automatically reset to 95%.

Q: The battery cannot be fully charged to 100%?

A: The battery will stop charging when the battery voltage reaches the charge voltage set in the PV Master App.

Page 32

User Manual V1.1-2022-01-05 04 OTHER

Q: Why does the battery switch always trip when it starts up (lithium battery)?

A: The switch of the lithium battery trips because of following reasons:

1. BMS communication fails.

2. The battery SOC is too low and the battery trips to protect itself.

3. An electrical short-circuit has occurred on the battery connection side. Alternatively, for other reasons, Please contact the after-sales department.

Q: Which battery should I use for the inverter?

A: For the inverter, it can connect to lithium batteries which have compatibility with inverters with nominal voltages from 180 V to 600 V. For compatible lithium batteries, please refer to the battery list in the PV Master App.

About PV Master Operation And Monitoring

Q: Why can't I save settings on the PV Master App?

A: This could be caused by losing the connection to Solar-Wi-Fi *.

1. Make sure you have already connected to Solar-Wi-Fi* (make sure that no other devices are connected) or to the router (if Solar-Wi-Fi* is connected to the router). The APP homepage shows the connections.

2. Make sure you restart the inverter 10 mins after you have changed any settings because the inverter will save the settings every 10 mins while operating in normal mode. We recommend that parameter settings be changed when the inverter is in wait mode.

Q: Why are the data displayed on the homepage dierent from the param page, like charge/ discharge, PV value, load value, or grid value?

A: The data refresh frequency is dierent, so there will be data discrepancies between dierent

pages on the APP as well as between these shown on the portal and APP.

Q: Some columns show NA, like battery SOH, etc. Why does that happen?

A: 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 Smart Meter And Power Limit Function

Q: How to activate the output power limit function?

A: This function can be activated by following these steps:

1. Make sure the Smart Meter connections and communications are functioning correctly.

2. Turn on the export power limit function and set the maximum output power to the grid on the APP. Note: Even if the output power limit is set to 0W, there might still be a deviation of a maximum of 100 W when exporting to the grid.

Q: Why is there still power exporting to the grid after I have set the power limit to 0 W?

A: The export limit could theoretically be 0W but there will be a deviation of around 50–100 W.

Q: Can I use other meter brands to take over from the Smart Meter in the system or to change

settings in Smart Meter?

A: 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.

Q: What is the maximum current allowed to pass through the CT on the Smart Meter?

Page 33

04 OTHER User Manual V1.1-2022-01-05

A: The maximum current for the CT is 120A.
