Only qualified cables under the local electrical safety laws and
regulations and comply with the technical parameters of this manual are
allowed to connect to the inverter.
Only with the permission of the local electric power company can the
inverter be connected to the utility grid.
Need to install an AC breaker between the grid and the energy storage inverter (recommend
250V/30A).For safe system operation, the recommended wire sizes are as follows:
Wire specification
Please follow the steps below to install the grid and load wiring:
(1) Before connecting the AC power grid cable to the energy storage inverter, 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 inverter must be reliably
grounded.
(2) Connect the three wires of the single-phase public power grid L, N, and PE to the AC terminal
and lock them according to Figure 5.2. The crimping torque is 1.2N·m. Ensure that the wire
conductor is crimped firmly and not exposed, then connect the AC terminal to the AC port of the
energy storage inverter. Turn the connector cover until you hear the sound ‘click’.
(3) Connect the three wires of the load L, N, and PE to the quick-connect terminal and lock them
as shown in Figure 5.2. The crimping torque is 1.2N·m, ensuring that the wire conductor is not
exposed and crimped firmly, then connect quick-connect terminal to the Load port of the energy
storage inverter. Turn the connector cover until you hear the sound ‘click’.
