2.1 Important Safety Instructions
Danger! Electric shock and high voltage. Do not expose the storage unit to temperatures in excess of 45°C. Do not subject the storage unit to any strong force. Do not touch uninsulated cable termination. Do not soak the storage unit in water or expose it to moisture
environment. Do not touch the case of the storage unit when it is wet in case of
electric shock. Do not dispose of batteries in fire. The batteries may explode! Do not place the storage unit near a heat source, such as direct
sunlight, a fireplace. Keep inflammable and explosive dangerous items or flames away
from the storage unit. Do not charge or discharge damaged storage unit. Before performing any work on the storage unit, please disconnect
the storage unit from all voltage sources as described in this document. Warning! Installation, repair, recycling, and disposal of storage unit must be performed by qualified personnel in accordance with national and local standards and regulations. Risks of chemical burn electrolyte or toxic gases. Do not place heavy objects on the top of the system. Do not connect any un- dedicated battery pack to TSUN storage unit. If the moisture penetrates the system (e.g., due to casing damage), please do not install or operate the system. Do not use wet hands to touch the system. Any behavior to change the functionality of the product without permission will cause fatal injury to the operator, third parties, and equipment. TSUNESS is not responsible for these losses and warranty claims. To ensure property and personal safety, the batteries and inverter shall be well grounded.
5

Caution! Do not modify or tamper with storage unit and other components of
the system. Risk of injury by hoisting or falling system Inverters and batteries are heavy and personal injury can be
caused if the inverter or battery is improperly lifted or dropped during transport or improper operation when attached or removed from walls. Lifting and moved the products shall be conducted by more than one person. Note Do not extend other brands of batteries at the battery port. Storage unit outputs AC power directly to the utility grid and the backup loads. Do not reverse output of these two AC terminals of the inverter.
2.2 Explanation of Symbols
This section explains all the symbols shown on the inverter and on the type label.
CE mark. The inverter complies with the requirements of the applicable CE guild lines.
Dangerous electrical voltage The device is directly connected to public grid, thus all work to the battery shall only be carried out by qualified personnel. Do not touch any internal parts of the inverter being disconnected from the mains, battery and PV input for 5 minutes. Danger of hot surface The components inside the device will release a lot of heat during operation. Do not touch metal plate housing of the inverter during operating.
Danger. Risk of electric shock!

Recyclable
2.3 Emergency situation
Despite of its careful and professional protection design against any hazard results, damage of the battery may still occur. If a small amount of battery electrolyte is released due to a serious damage of the outer casing; or if the battery explodes due to not being treated timely after a fire breaks out nearby, and leaks out poisonous gases such as carbon monoxide, carbon dioxide etc., the following actions are recommended: 1) Eye contact: Rinse eyes with a large amount of running water and seek
medical advice 2) Contact with skin: Wash the contacted area with soap thoroughly and
seek medical advice 3) Inhalation: If you feel discomfort, dizziness or vomiting, seek medical
advice immediately. 4) Use a FM-200 or Carbon Dioxide (CO2) fire extinguishers to extinguish
the fire if there is a fire in the area where the battery pack is installed. Wear a gas mask and avoid inhaling toxic gases and harmful substances produced by the fire. 5) Use an ABC fire extinguisher, if the fire is not caused by battery and not spread to it yet. 6) PV modules should have an IEC61730 class A rating. 7) The applicable grid types for the TSOL series are TN-S, TN-C, TN-C-S and TT. When applied to the TT grid, the voltage of N to PE suggests less than 30V.
7

Warning! If a fire has just occurred, try to disconnect the battery circuit breaker and
cut off the power supply first, but only if you can do so without endangering yourself. If the battery is on fire, do not attempt to extinguish the fire and evacuate the crowd immediately.
Potential danger of damaged battery:
Chemical Hazard: Despite of its careful and professional protection design against any hazard results, rupture of battery shall still occur due to mechanical damage, internal pressure etc., and may result in a leakage of battery electrolyte. The electrolyte is corrosive and flammable. When there is fire, the toxic gases produced will cause skin and eyes irritation, and discomfort after inhalation. Therefore: 1) Do not open damaged batteries. 2) Do not damage the battery again (shock, fall, trample, etc.). 3) Keep damaged batteries away from water (except to prevent an energy
storage system from catching fire). 4) Do not expose the damaged battery to the sun to prevent internal
heating of the battery.
Electrical hazard: The reason of fire and explosion accidents in lithium batteries is battery explosion. Here are the main factors of battery explosion: 1) Short circuit of battery. Short circuit will generate high heat inside
battery, resulting in partial electrolyte gasification, which will stretch the battery shell. The temperature reaching ignition point of internal material will lead to explosive combustion. 2) Overcharge of battery. Overcharge of battery may precipitate lithium metal. If the shell is broken, it will come into direct contact with the air, resulting in combustion. The electrolyte will be ignited at the same time, resulting in strong flame, rapid expansion of gas and explosion.

Introduction

3.1 Scope of application
TSUN provide two kinds of storage unit product, AC Coupled Unit and Hybrid Storage Unit. AC Coupled Unit doesn’t have PV inputs and is used in energy storage retrofits.
Hybrid Storage Unit has two PV inputs and is used in new installation systems.
In daytime, solar power supports the loads first while the surplus power will be stored by storage unit, to improve self-consumption rate. In peak power price hours, power from storage unit supports the loads; while in valley power price hours, storage unit is charged by the grid. Finally, a balance could be realized.
9

In case of grid fault, storage unit will make sure no outage in the loads, achieving UPS function.
Storage unit has two parts, inverter and battery. Storage unit can have a capacity expansion according to user demands and the modular design of the slave device makes it easy to install wiring.
