•This document is subject to update from time to time due to product version upgrading or
other reasons. Unless otherwise specified, the contents of this document cannot replace the
safety instructions provided in the product label or user manual.All descriptions provided
herein are intended as use guidance only.
•Read this document carefully to understand the products and precautions before installing
the inverter.
•All operations of the inverter must be conducted by professional and qualified technicians
who are familiar with the relevant local standards and safety regulations at the place where
the invert is installed.
•When the inverter is operated, it is necessary to use insulating tools and wear personal
protective equipment to ensure personal safety. Wear anti-static gloves, anti-static bracelet
and anti-static clothing, etc. when touching electronic devices, to protect the inverter against
static.

Contact the supplier for this document.
2.2 Safety of photovoltaic module
DANGER
Please connect the DC cable of the inverter by using DC wiring terminal supplied with the
product.
Using other DC wiring terminals may lead to serious consequences, and the equipment
damage caused therefore is not the equipment manufacturer’s responsibility.

~ 3 ~
WARNING
•Make sure to properly earth the component frame and the support system.
•After the DC cable is connected, make sure that the cable is tightly connected without
looseness.
•Measure the positive and negative poles of DC cable by a multimeter to ensure that the
positive and negative poles are connected correctly and without reverse connection, and
the voltage is within the allowable range.
•Do not connect the same PV string to multiple inverters in series; otherwise the inverter
may be damaged.
•The photovoltaic module used with the inverter must comply with ClassA standard of
IEC61730.

approved batteries is available from the official website.
•Before installing the inverter, please carefully read the user manual of the battery to understand
the product and precautions, and strictly follow the operation requirements provided in the user
manual of the battery.
•If the battery has been completely discharged, charge the battery in strict accordance with the
user manual of the battery.
•The battery current may be affected by some factors, such as temperature, humidity and
weather conditions, etc., which may cause battery current limit and affect carrying capacity.
•If the battery does not work, please contact the after-sales service center as soon as possible.
Otherwise, the battery may be permanently damaged.
•Measure the positive and negative poles of DC cable by a multimeter to ensure that the positive
and negative poles are connected correctly, and the voltage is within the allowable range.
•Do not connect a single battery pack to more than one inverter; otherwise the inverter may be
damaged.

~ 5 ~
2.5 Personnel requirements

Chapter 3 Product Description
3.1 Product description
EAHI-3000~6000-SLinverter is used to control and optimize the energy flow in the photovoltaic
system through an integrated energy management system. With the inverter, the power energy
generated in the photovoltaic system can be supplied for the load, stored in the battery, and
outputted to the grid. The inverter integrates with power supply, battery and Internet for
connection with grid, photovoltaic panels and the Internet of things to supply the power for
families, small supermarkets, farms and other places.
Product features:
Graphic LCD and key design, user-friendly interface
One-key remote control and OTA upgrade function accessible to digital power station
maintenance
24-hour intelligent energy management to understand the status of photovoltaic power
station in real time
Charging and discharging time and power settable flexibly for peak load shifting
Uninterruptible power supply, switchable within 20ms
Continuous off-grid power supply capacity up to 6KW
High charging and discharging efficiency to improve the economic benefits of system
Intelligent BMS function to improve battery reliability
Compatible with lead-acid and lithium batteries, which can match economic solutions of
different markets
High frequency isolation technology used to provide higher system safety and long service
life
3.2 Application scenarios
WARNING
•The photovoltaic system is not suitable for connection with the devices requiring stable
power supply, such as life-sustaining medical devices. Make sure that no personal injury is
caused in case of system failure.
•If the photovoltaic system is not equipped with a battery, it is not recommended to use the

~ 7 ~
BACK-UP function. The power consumption risk of the system caused therefore is excluded
from the warranty of the equipment manufacturer.
•The battery current may be affected by some factors, such as temperature, humidity,
weather conditions, etc., which may cause battery current limit and affect carrying capacity.
•If overload protection is triggered on the inverter for single time, the inverter can be restarted
automatically; if overload protection is repeated, the restarting time of the inverter will be
prolonged. If it is required to restart the inverter as soon as possible, the inverter may be
restarted immediately by App.
•If, during grid failure, load capacity is more than the rated power of the inverter, the off-grid
function of the inverter will be disenabled automatically; when the inverter is restarted, close
large load to ensure that the load power is less than the rated power of the inverter.
•The inverter has overload capacity and EPS function at the BACK-UP output port (switching
time <20ms), and may supply the power for normal use in ordinary domestic load in case of
grid failure. To ensure EPS switchover and power supply stability of the load, do not use the
loads requiring high starting current as much as possible, such as high-power water pumps.
The supported load sizes are as follows:
Total power of inductive load and capacitive load ≤ 1 x rated output power of inverter
