Introduction
The Centauri Energy Server is the first comprehensive, stand-alone, fully integrated power electronics
hardware + software platform that delivers utility grade power from any combination of DC or AC
generation sources and storage. The Centauri replaces integrated systems comprised of multiple
components (PV inverter + charge controller + battery inverter + communication software and
hardware + safety devices etc.) and can be deployed in any location, to service any kind of load profile
(from kW to MW), with or without grid access or generator availability.
The Centauri Energy Server is equipped with high speed digital DSP core control devices, advanced
high-speed IBGT, MOSFET and other power devices, combined with disturbance type (SVPWM) MPPT
control technology with pulse width modulation and double transformation system so that it can
quickly track the polar plate for the control system of high power, load change and high efficient
multiple levels under the control of the high speed DSP system to provide the load with high quality
power supply featuring stable voltage and frequency even in the cases of a sudden change of AC input
voltage and AC frequency, over/under voltage.

1Safety Precautions:
Please comply with the following precautions for safe use:
•Installation and maintenance must be done only by authorized technicians.
•During the installation of this product, the distance between the Energy Server and the wall
should be more than 1000 mm to ensure ventilation and heat dissipation of the Energy Server.
•The temperature of the surface of the cabinet may rise when the product is in normal operation.
•Since the battery packs of all series Energy Severs are external, the product should be equipped
with the battery packs which should meet the requirements of the rated voltage of the
equipment when in operation.
•Do not open the cabinet of the Energy Sever, otherwise it may cause an electric shock.
•The internal inspection and maintenance should be conducted only by the authorized technical
personnel.
•After the Energy Server is turned OFF, its voltage may be still high for a long time, please do not
open the cabinet because it may cause an electric shock.
•The “Manual Bypass” switch is used for maintenance and repair of the product; therefore,
authorized technical personnel should open it.
•This system is provided with multiple PV inputs; therefore, it should be connected with the
independent loop, without the electrode grounded.
•The “EPO”button on the panel is used for the emergency stop power supply (power off) of the
Energy Server, please pay attention to its operation.
•The internal short circuit of the Energy Server will lead to the risk of an electric shock or a fire,
therefore under no circumstances should liquids be placed on it in order to avoid electric shock
or other hazards.
•Please use the dry powder fire extinguishers in the event of a fire, because the use of the liquid
fire extinguisher may cause an electric shock.
•Please install the external power switch near the Energy Server so that the power supply can be
cut OFF in the event of emergency.
•Do not store or install the Energy Server:
→Outdoors
→In locations without cross ventilation.
→In locations near or where there is combustible gas, corrosive substances or dust.

→In locations with unusually high or low temperatures (above 40oC or below 0oC) or high
humidity (90%).
Warning!
1. The Energy Server must be reliably grounded.
2. The loss caused by the improper operation may be huge, please operate
the equipment by following the requirements of specifications.
