WARNING: Lethal voltage
• Review the system conguration to identify all possible sources of energy.
Ensure ALL sources of power are disconnected before performing any
installation or maintenance on this equipment. Conrm that the terminals are
de-energized using a validated voltmeter (rated for a minimum 10oo VAC and
1000 VDC) to verify the de-energized condition.
• Do not perform any servicing other than that specied in the installation
instructions unless qualied to do so, or have been instructed to do so by

User Manual V1.4-2022-06-30
Safety Precautions
• To avoid electric shock, disconnect the DC input and AC input of the inverter at
least 5 minutes before performing any installation or maintenance.
• Completely disconnect all sources of power before proceeding with any
maintenance. Do not open the upper Inverter compartment of the system!
• Do not tighten the AC and DC terminals or pull on the AC and DC wiring when
the inverter is running.
CAUTION: Equipment damage
• When connecting cables from the inverter to the battery terminals, ensure the
proper polarity is observed. Connecting the cables incorrectly can damage or
destroy the equipment and void the product warranty.
• Thoroughly inspect the equipment prior to energizing. Verify that no tools or
equipment have been inadvertently left behind.
• Ensure clearance requirements are strictly enforced. Keep all vents clear of
obstructions that can prevent proper air ow around, or through, the unit.
• Sensitive electronics inside the equipment can be destroyed by static electricity.
Be sure to discharge any static electricity before touching the equipment and
wear appropriate protective gear.
CAUTION: Equipment damage
• Do not open the upper front cover of the inverter. Apart from performing work
at the wiring terminals (as instructed in this manual), touching or changing
components without authorization may cause injury to people, damage to the
inverter and annulment of the warranty.
• Static electricity may damage electronic components. Take appropriate steps to
prevent such damage to the inverter; otherwise the warranty may be annulled.
• Ensure the output voltage of the proposed solar array is lower than the
maximum rated input voltage of the inverter; otherwise the Inverter may be
damaged and the warranty annulled.
• Solar modules should have an IEC61730 Class A rating.
WARNING: Burn hazard
• External and internal parts can become hot during operation. Do not remove
the cover during operation or touch any internal parts. Be sure to allow
sucient time for internal parts to cool down before attempting to perform any
maintenance.
WARNING: Fire hazard
• Do not keep combustible or ammable materials in the same room as the
equipment. The GoodWe Smart Hybrid contains relays and switches which are
not ignition protected.
• Ensure AC, DC and ground cable sizes conform to local codes. See product
manuals for minimum size requirements. Ensure all conductors are in good
condition. Do not operate the unit with damaged or substandard cabling.

WARNING: Explosion, electrocution or re hazard.
• Ensure that all cables are properly sized.
• Ensure clearance requirements are strictly enforced around the batteries.
• Ensure the area around the batteries is well ventilated and clean of debris.
• Never smoke, or allow a spark or ame near the batteries.
• Always use insulated tools. Avoid dropping tools onto batteries or other
electrical parts.
• Never charge a frozen battery.
• If a battery must be removed, always remove the grounded terminal from the
battery rst. Make sure all devices are de-energized or disconnected to avoid
causing a spark.
Battery Safety
IMPORTANT
• Use the battery types recommended by GoodWe. Follow the battery
manufacturer's recommendations for installation and maintenance.
• Insulate batteries appropriately against freezing temperatures. A discharged
battery will freeze more easily than a charged one.
• If a remote or automatic generator control system is used, disable the
starting circuit and/or disconnect the generator from its starting battery while
performing maintenance to prevent accidental starting.

1.1 Functions
1.2 Features
1.3 Battery Selection
01 Introduction
The GoodWe Smart Hybrid Inverter enables the connection of two solar arrays, a battery bank,
and utility grid and provides backup power for AC loads. The energy produced by the solar
array is automatically directed to the battery, utility grid and/or the AC loads depending on
operating conditions for the highest performance and best economic return. The system’s goal
is to maximize the use of the solar energy generated while minimising the amount of energy
consumed from the utility. The back-up functionality enables users to have continued supply of
electricity in the event of a utility power outage. The GoodWe Smart Hybrid Inverter includes all
of the following functions, components and features in a single easy-to-install product.
• High eciency grid-tie utility interactive inverter
• Utility grid energy metering system
• Powerful backup inverter for AC loads
• Utility powered battery charger
• Dual Maximum Power Point Tracking (MPPT)
• Battery charge control
• Solar array ground fault and insulation monitoring protection
• Programmable GoodWe Smart Hybrid system controller
• Performance monitoring with WiFi and web interface
• Utility grid overcurrent protection and disconnect
• Battery overcurrent protection and disconnect
• AC backup loads overcurrent protection and disconnect
• AC backup loads manual bypass switch
• Weatherproof enclosure, can be installed outdoors (IP65)
Note: The GoodWe GW5048-ESA is a transformerless inverter, all other components of the solar system
must be compatible with this type of inverter architecture.
IMPORTANT
Battery charger settings need to be correct for the intended battery type.
Always follow relevant standards and battery manufacturer recommendations.
When planing a battery bank, consider the following:
• The GW5048-ESA is designed to work with lithium-ion batteries only.
• The GW5048-ESA is designed to work with a nominal 48-Volt battery bank. The actual voltage
of battery can vary during operation from 40 to 60 VDC depending on the battery type and
number of cells in series.
• A vented enclosure for the battery bank may be required by standards. This is recommended
in most cases for safety reasons and to prevent unauthorised access.
• The GW5048-ESA should be connected to a grid or microgrid when installed, and remain
on-grid at least 80% of its life and operation. Prolonged use of the GW5048-ESA o-grid may
result in decreased life of the batteries installed with the system.

2.1 Backup AC Loads
2.2 Inverter Operating Modes
02 Planning
The GoodWe Smart Hybrid Inverter can provide up to 5000 Watts of continuous AC power for
AC loads, which are connected to the backup loads. The system can provide a maximum of 6900
watts of AC power for up to 10 seconds to start loads, which require a higher amount of power
initially. The output of the inverter is reduced if the ambient temperature exceeds 45℃ and the
system will shut o if the ambient temperature exceeds 60℃.
Note: The backup circuit shares the neutral line with the grid and hence MEN integrity is maintained in
all modes of the inverter's operations.
Examples of ACCEPTABLE AC loads to connect to
the back-up AC load circuit:
• Small plug-in appliance such as cookers,
microwaves, TV, radios, computers
• Lighting (compact uorescent or LED
recommended)
• Refrigerators and freezers
Examples of UNACCEPTABLE AC loads not to
connect to the backup AC load Circuit:
• Water heaters
• Air-conditioners
• Electric cooktop ranges or ovens
• Spa/saunas
• Water pumps
Figure 3: Examples of acceptable backup AC loads
Figure 4: Examples of unacceptable backup AC loads
Note: These examples of dierent operating modes are simplied and do not include the small amount
of losses involved in the energy conversion process. They should not be considered as representative of
real world system performance.
There are four working modes for the inverter: general mode (default), o-grid mode, standby
mode and economic mode, which can be set by the PV Master app or port.
2.2.1 General Mode
General mode: In this mode, the power generated by photovoltaic gives priority to the load
power supply, the remaining power charges the battery, if the power is still remaining, then
selectively grid-connected.

O grid mode: Photovoltaic and battery constitute a pure o-grid system, suitable for non-grid
areas.
Standby mode: Battery discharges only in abnormal condition of grid, similar to uninterrupted
power supply. When the grid is normal, the battery does not discharge, only charges until the
battery is full, when the grid is cut o, and the battery can supply power to the load.
Economic mode: charging at valley price, discharging at peak price, charging/discharging time
and power can be set by the PV Master app.
