1.1 Operation Modes Introduction
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 insucient to meet self-
consumption needs. If battery power is not sucient, 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.
ES system normally has the following operation modes based on your conguration 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
sucient, 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.

01 Introduction User Manual V1.1-2022-01-05
Any installation or operations on the inverter must be performed by qualied 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 open-
circuit 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).
12
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 dierent 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 Specication
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.
Requirement of AC cable connected to On-Grid and Back-Up side.
Make sure the inverter is totally isolated from any DC or AC power before connecting the
AC cable.
Note:
1. Neutral cable shall be blue, line cable shall be black or brown (preferred) and protective earth cable
shall be yellow-green.
2. For AC cables, PE cable shall be longer than N&L cables, so in case that the AC cable slips or is taken
out, the protecting earth conductor will be the last to take the strain.

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)
15
02 Installation Instructions User Manual V1.1-2022-01-05
Note:
For convenient maintenance, please install a SP3T switch on back-up and on-grid side. Then it is
adjustable to support load by back-up or by grid or default settings.
1. Back-up load is supplied from back-up side.
2. Back-up load is isolated.
3. Back-up load is supplied from grid side.
Declarations For Backup Overload Protection

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 Conguration
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.
User Manual V1.1-2022-01-05 04 OTHER
29
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 dierent from the param page, like charge/
discharge, PV value, load value, or grid value?
A: The data refresh frequency is dierent, so there will be data discrepancies between dierent
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?
04 OTHER User Manual V1.1-2022-01-05
30
A: The maximum current for the CT is 120A.
Other Questions
