6. Electrical Installation
Caution
1) Electrical risks must be prevented during installation, distribution,
generation, and maintenance of PV module.
2) During installation of PV module, system voltage should not exceed
[IEC1000V].
3) When installing the system, use same rate of model [If you use a
electrically and physically different type of module, output capacity or
system performance may be reduced due to fire].
4) When wiring, you should connect polarity appropriately, and if not, it can
cause abnormal generation performance and PV module degradation by
fire.
5) For the reverse current value, refer the Fuse rating value specified in “9.
Detailed module specification’. If exceed its value, connect the rated
overcurrent protective device(permitted by local regulation) to the
module string in series wiring.
6) Junction box is in the rear surface of the module. This box is an important
device for the module generation, and never unpack it in any
circumstance in the field.
[Once the junction box is opened, warranty will be invalidated. ]
7) If the PV module have any electrical problem, you should inspect the
module according to the warranty term provided by S-Energy, and return
it to S-Energy for repair and replacement.
Material :
All the wire for the PV module connection should be configured with PV cable only
.
[Cable for PV : double insulation, UV resistance, temperature resistant for more than minimum 90
℃
] Use copper
wire for all wiring.
Diameter: At least larger than minimum 12AWG [4
㎟
]
[wiring diameter should confirm the local regulation, and S-Energy Co., Ltd. recommends the customer use wires
with a diameter larger than the above number at minimum.]

| Series Wiring|
- Wires may be connected in series to generate the required voltage output.
- Series wiring should be configured at the same rate(current)
| Parallel Wiring |
- Wires may be connected in parallel to generate the required current output.
- Even when wires are connected in parallel, the intensity of voltage in inverter should
be considered.
- Before connected to other modules, all modules should be wired with a fuse. For the
number of additional fuses and maximum number of module should refer and follow
the related local regulations.
