Anti-interference property from internal components.
Anti-interference property from outside.
Electromagnetic emission impact on the environment
Inverter may generate some noise and electromagnetic radiation during
operation. According to EMC emission and noise level, inverter should be used in
industrial environments. Hence, all personnel should not stay long near the
2.7 . Important note
Information
Item 1: Static electricity can cause damage to the inverter
Electrostatic discharge may cause unrecoverable damage to inverter internal
components!
When operating the inverter, operator must comply with anti-static protection
norms!
Item 2: Restriction
The inverter cannot be directly used to connect the life support equipment
and medical equipment!
Item 3: Precautions
Make sure installation tools or other unnecessary items are not left inside the
inverter before starting up.
Item 4: Maintenance notice
Maintenance can only be carried out after the inverter totally discharged.
Product description 3
ATESS HPS50 bidirectional battery inverter is designed for energy storage
system, it converts DC current generated by battery bank into AC current and feed
it into the load/grid, also it can take power from solar inverter or grid to charge
3.1 Energy Storage system
Structure of a typical energy storage system is shown as below
Figure 3- 1 Grid-connected energy storage system
ATESS HPS50 bidirectional battery inverter converts DC current generated by
battery into AC current. Then the AC current is filtered into sine wave electricity
and fed into the grid through a isolating transformer. It can also converts grid
power to DC to charge battery. The circuit diagram is as below:
