Symbol Usage
Danger to life from electric shock
• Before performing any work on the inverter, disconnect all DC and AC power
from inverter and wait for at least 10 minutes. Hazardous voltage will exist
for up to 10 minutes after disconnection from power supply.
• Never insert or remove the AC or DC connections when the inverter is
running.
• Any live parts connected to battery ports cannot be touched before removing
all the power from inverter for 10 minutes because there is still danger to life
even battery voltage is lower than 60 V.
• Do not touch DC conductors or any non-isolated cable ends.
• The mounting location must be inaccessible to children.
• Never touch either the positive or negative pole of PV connecting device.
Strictly prohibit touching both at the same time.
WARNING
Risk of burns from hot surfaces
• The surface of the inverter might exceed 60℃, and touching the surface may
result in burns.
• Do not touch hot surfaces before the inverter cools down.

WARNING
• Only authorized service personnel are allowed to install the inverter or
perform servicing and maintenance.
• All powers, both AC and DC, should be disconnected from inverter before
attempting any maintenance, cleaning or working on any circuits connected
to inverter.
• Attempting to service the inverter yourself may result in a risk of electric
shock or fire and will void your warranty.
• Keep away from flammable and explosive materials to avoid fire disaster.
• The installation place should be away from humid or corrosive substances.
• The unit contains capacitors that remain charged to a potentially lethal
voltage after the mains, battery and PV supply have been disconnected.
• When accessing the internal circuit of inverter, wait for at least 10 minutes
after disconnecting the power.
• The inverter has a transformer-less design on PV side. Neither positive nor
negative terminals of PV panels should be grounded.
• The frames of PV panels should be grounded for safety reasons.
• Ensure that existing wiring is in good condition and no wire is undersized.
• Do not disassemble any parts of inverter which are not mentioned in
installation.
• Authorized service personnel must use insulated tools when installing or
working with this equipment.
• PV modules shall have an IEC 61730 class A rating.
• The minimum rated temperature of the wire used is 90℃ (194℉).
• All electrical connections must be in accordance with local and national
standards.
• Only with permission of the local utility grid company, the inverter can be
connected to the utility grid.
• Do not open the inverter cover or change any components without
authorization, otherwise the warranty commitment for the inverter will be
invalid.
• Appropriate methods must be adopted to protect inverter from electrostatic
discharge; any damage caused by ESD is not warranted by the manufacturer.
• Prior to the application, please read this section carefully to ensure the
correct and safe application. Please keep the user manual properly.
• The manual contains no instructions for user-serviceable parts. See Warranty
for instructions on obtaining service.
• If an error occurs, refer to troubleshooting or contact your local distributor or

2.2 Operating Modes
Main Operation Modes
The following operation modes are applicable for the HYT series inverter, and are also applicable for the
HAT series inverter which is connected to the PV inverter through the GEN port.
Self-consumption
Mode
In the daytime, solar energy is
used to power the loads first,
and surplus energy is stored in
the battery. After the battery has
been fully charged or reaches
its maximum charge power, the
excess solar energy is fed into the
grid (or limited if necessary).
At night, the battery discharges
for the loads first, and once the
battery power is insufficient, the
grid supplies power to the loads.
In this mode, battery cannot be
recharged from grid at night.
00:00 24:00
Power flow of self-consumption mode
Economic Mode
In this mode, the time of battery
charge and discharge needs to be
set. Meanwhile, the battery can
be forced to charge from the grid
during the preset charge time.
For instance, the battery could be
charged or discharged according
to valley or peak electricity price.

battery always has enough energy
to handle critical loads.

2.3 System Diagram
The HYT-HV series inverter can be connected to a battery and PV panels to form a PV Energy Storage
System (ESS). In the event of a grid outage, it can be used as an emergency power supply (EPS) through the
self-consumption of solar energy. It can either form a DC-coupled system for a new installation or an AC-
coupled system to retrofit existing installations.
• This diagram is a simplified system sketch that is only intended to explain
system architecture.
• Please refer to https://www.hoymiles.com for compatible battery list,
and the user should first contact Hoymiles for technical consultation and
obtain official confirmation prior to installing any battery not included in

The HAT-HV series inverter can be connected to a battery and any grid-connectd PV inverters to form a PV
Energy Storage System (ESS). In the event of a grid outage, it can be used as an emergency power supply

3.3 Mounting
3.3.1 Selecting the Mounting Location
• Make sure there is no electrical connection before installation.
• In order to avoid electric shock or other injuries, make sure that holes are
not be drilled over any electrical parts or plumbing installations.
WARNING
• Make sure the inverter is correctly installed according to the following list.
Any incorrect installation would require a risk assessment.
• In order to prevent inverter damage and personal injury, make sure the
inverter is carefully moved.
• The inverter can not be vertically placed on the ground, since the terminals
and ports at the bottom of the inverter can not bear the weight of inverter.
Such protection materials as foam and paper can be used to protect the
enclosure if it is placed on the ground.
NOTICE
Check List
1. The inverter installation should be protected by shelter from direct sunlight or bad weather such as
snow, rain or lightning.
2. The inverter should be installed on a solid surface which is suitable for the inverter’s dimensions and
weight.
3. The inverter should be installed vertically or at a maximum back tilt of 15°. Leave enough space around
the inverter according to the figure below.
4. The inverter should be installed in an environment with good ventilation and heat dissipation
conditions.
5. The ambient temperature should be between -25°C and 45°C. High ambient temperatures will cause
power derating of the inverter.
6. The relative humidity should be less than 95%, without condensing.
7. The inverter should be installed at eye level for convenient maintenance.
8. The product label on the inverter should be clearly visible after installation.
9. The inverter should be installed far from flammable materials.

Before connecting the grid, please make sure all requirements listed below are
followed.
• Use the grid connector from the accessory box. Damage to the device due
to the use of incompatible connector shall not be covered by the warranty.
• An independent three or four-pole circuit breaker must be installed on the
output side of the inverter to ensure safe disconnection from the grid.
• Multiple inverters cannot share one circuit breaker.
• Never connect a load between the inverter and the circuit breaker.
• Do not connect the AC circuit breaker until all inverter electrical connections
are completed.
Procedure
