1.2 Operation Modes:
There are three basic modes that end users can choose via inverter screen/APP.
03 04
• BAT PRIORITY: Under this mode, the battery is only used as a backup power supply when
the grid fails and as long as the grid works, the batteries won’t be used to power the loads.
The battery will get charged with the power generated by the PV system or from the grid.
• PEAK SHIFT: This mode is designed for time-use mode customer. The customer is able to
set up the charging/discharging time & power via inverter screen or APP.
• SELF CONSUME: The energy generated by the solar panels will be used in the following
order: Feed the home loads; Charge the battery and then, feed into the grid.When the sun is
off, the load will be supported by battery to enhance self consumption. If the power supply
from the batteries is not sufficient, the grid will support the load demand.

1.3.2 Operator Requirements
The operators should get a professional qualification, or be trained.
The operators should be familiar with the whole storage system, including compositions and
working principles of the system.
The operators should be familiar with the Product Instruction.
While maintaining, the maintainer is not allowed to operate any equipment until all the
equipment has been turned off and fully discharged.
The warning signs contain important information for the system to operate safely, and it is
strictly prohibited to tear or damage them. Ensure that the warning signs are always well-
functioned and correctly placed. The signs must be replaced immediately when damaged.
1.3.3 Protection of Warning Sign
1.3.1 Manual Keeping
This manual contains important information about operating the system. Before operating,
please read it very carefully.
The system should be operated in strict accordance with the instructions in the
manual,otherwise it can cause damages or loss to equipment, personnel and property.
This manual should be kept carefully for maintenance.

User Manual User Manual
1.4.1 Hazard Information
1.3.4.Setting of Warning Sign for Safety
This sign indicates a hazardous situation which, if not avoided,
could result in death or serious injury!
This sign shows danger of hot surface!
Refer to the operating instructions.
The E8KT/E10KT/E12KT must not be touched or put into service until
5 minutes after it has been switched off or disconnected to prevent an
electric shock or injury.
During instruction, maintenance and repair, follow the instructions below to prevent
non-specialist personnel from causing misuse or accident:
Obvious signs should be placed at front switch and rear switch to prevent accidents caused
by false switching.
Warning signs should be set near operating areas.
The system must be reinstalled after maintenance or operation.
To ensure the electrical parameters to match requirements, related measuring equipment are
required when the system is being connected or tested.
Ensure that the connection and use matched specification to prevent electric arcs or shocks.
It is very likely that moisture may cause damages to the system. Repair or maintaining
activities in wet weather should be avoided or limited.
The battery system is part of the energy storage system which stores life-threatening high
voltage even when the DC side is switched off. Touching the battery outlets is strictly
prohibited. The inverter can keep a life-threatening voltage even after disconnecting it from the
DC and / or AC side. Therefore, for safety reasons, it must be tested with a properly calibrated
voltage tester before an installer works on the equipment.
Exempt from classification according to Australian WHS regulations.
Classification of the hazardous chemical
Other hazards
This product is a Lithium Iron Phosphate Battery with certified compliance under the UN
Recommendations on Transport of Dangerous Goods, Manual of Tests and Criteria, Part III,
subsection 38.3. For the battery cell, chemical materials are stored in a hermetically sealed
metal case, designed to withstand temperatures and pressures encountered during normal
use. As a result, during normal use, there is no physical danger of ignition or explosion and
chemical danger of hazardous materials' leakage. However, if the product is exposed to a fire,
added mechanical shocks, decomposed, added electric stress by misuse, the gas release
vent will be operated. The battery cell case will be breached at the extreme. Hazardous
materials may be released. Moreover, if heated strongly by the surrounding fire, acrid or
harmful fume may be emitted.

1.3.8. Information on environmental conservation and recycling
This Symbol indicates that the marked device must not be disposed of as normal
household waste. It must be disposed of at a collection center for the recycling of
electric and electronic equipment.
CAUTION:
Risk of injury through lifting or dropping the system. The inverter and battery are
heavy. There is risk of injury if the inverter or battery is lifted incorrectly or dropped
during transport or when attaching to or removing from the wall.
Lifting and transporting the inverter and battery must be carried out by more
than 2 people.
WARNING
Do not install the system in any environment of temperature below -25°C or over
60°C and in which humidity is over 95%.
Do not touch the system with wet hands.
Do not put any heavy objects on top of the system.
Do not damage the system with sharp objects.
Do not install or operate the system in potentially explosive atmospheres or
areas of high humidity.
Do not mount the inverter and the battery pack in areas containing highly
flammable materials or gases.
If moisture has penetrated the system (e.g. due to a damaged enclosure), do not
install or operate the system.
Do not move the system when it is already connected with battery modules.
Secure the system to prevent tipping with restraining straps in your vehicle.
A certified ABC fire extinguisher with minimum capacity of 2kg must be carried
along when transporting.
It is totally prohibited to smoke in the vehicle as well as close to the vehicle when
loading and unloading.
For the exchange of a battery module, please request for new hazardous goods
packaging if needed, pack it and let it be picked up by the suppliers.
In case of contact with electrolyte, rinse the affected areas immediately with
water and consult a doctor without delay.
Inverter
Risk of chemical burns from electrolyte or toxic gases. During standard operation, no
electrolyte shall leak from the battery pack and no toxic gases shall form. Despite careful
construction, if the Battery Pack is damaged or a fault occurs, it is possible that electrolyte
may be leaked or toxic gases formed.
Check the following parts list to ensure it is complete.

The transportation of E8KT/E10KT/E12KT must be made by the manufacturer or
an instructed . These instructions shall be recorded and repeated. personnel
DANGER
Do not touch uninsulated cable ends.
Do not touch the DC conductors.
Do not open the inverter and battery.
Do not wipe the system with damp cloth.
Have the system installed and commissioned by qualified with the personnel
appropriate skills only.
Prior to performing any work on the inverter or the battery pack, disconnect the
inverter from all voltage sources as described in this document.
Danger to life due to high voltages of the PV array, battery and electric shock. When exposed
to sunlight, the PV array generates dangerous DC voltage which will be present in the DC
conductors and the live components of the inverter. Touching the DC conductors or the live
components can lead to lethal electric shocks. If you disconnect the DC connectors from the
system under load, an electric arc may occur leading to electric shock and burns.
