System overview
There are different system configurations possible depending on the
user
's
requirements, existing electrical infrastructure and local
regulations. The distribution box must be configured to comply to the
grid operator requirements.
The inverter has an integrated AC relay to disconnect all phases and
Neutral from the grid in case of grid fault or grid outage.
The inverter's generation and feed-in limitation functions require the
use of an external measurement device to obtain grid information.
There are 3 system configurations:
System A: direct measurement of energy with CTs (up to 300 A)
System B: measurement of energy with energy meter + CTs
System C: measurement of energy with energy meter (up to 80 A)
NOTE
•
For System B, customers can choose different CTs based
on the installation. The secondary current must be 5 A.
CAUTION
•
In the following three situations, the system must be
connected to the fuse first and then to the machine's input
terminal:
•
Lead-acid battery
•
Lithium battery without BMS
•
Multiple lithium batteries connected to one input
