1. Introduction
Thank you for choosing ViTech Power energy storage system.
The energy storage module comprises of lithium ion rechargeable batteries with 5.12 kWh capacity, and
the controller enables a central of multiple modules.
This manual provides information regarding safety precautions to prevent possible accidents and how
to use the product.
Please read this manual carefully before use for safety and keep this manual handy for reference.
1.1. Main Features
Some main features of this product are:
nLong Life Span
The battery can be expected to remain serviceable for more than 10 years, considering that it is charged
and discharged once in a day at room temperature (25 °C).
nLong Life Span
Olivine-type lithium iron phosphate batteries with excellent thermal stability and storage characteristics
are used in this product. The module also incorporates a self-monitoring function for the detection of any
abnormalities in energy storage.
nCompact Design
The height is nicely designed in 3U, in favor of standard industrial applications.
nHigh Scalability
Multiple energy storage modules can be connected in parallel, and the capacity can be customized
according to the intended use.
1.2. Safety Precautions
ViTech Power products are designed with full consideration of safety. However, all electrical
appliances can be dangerous if used inappropriately; it can cause a fire or electric shock that leads to

2. Do not install upside down or sideways. The set may drop and cause injury.
nInstruction
Use the designated packaging materials for transportation. If you do not use the designated packaging
materials, the packaging material may be damaged by vibration during transportation and it may cause
injury.
nInstruction
Install based on the designated way of installation. If you do not follow the designated way of installation,
the set may drop due to the strength poverty and can cause injury.
nInstruction
If you ignore any of the following instructions, it can cause injury or damage to nearby
products.
