4.3.2 Grid and load connection
Only qualified AC transmission cables under the local electrical safety laws and
regulations and comply with the technical parameters of this manual are allowed to
connect to the energy storage integrated machines.
Please install an AC breaker between the battery and the energy storage integrated machine (250 A-30
A recommend).
Recommended wire specifications for safe system operation are as shown in the following table.
• Before connecting the AC power grid cable to the energy storage integrated machine, the lightning
protection and short circuit protection measures must be taken in accordance with the local
electrical safety regulations. The PE cable (grounding cable) of the machine must be reliably
grounded.
Connect the three wires L, N, and PE of the single-phase public power grid to the corresponding
