user’s manual inverter SE2.8i - SE3.8i - SE4i - SE5i
The following three sections describe the wiring for the AC, DC, and communication ports. The wiring shall be done in the wiring box for the
SE 2.8i, SE 3.8i, SE 4i, and SE 5i. There is one (1) AC terminal block, a pair of DC terminal blocks and two (2) RJ-45 connectors in the wiring
box as shown in the figure 2.3.5. The AC terminal block is used to connect to the utility grid through a circuit breaker and distribution panel
according to national and local requirements. The DC terminal blocks are used to connect up to 4 PV strings in parallel in the wiring box. The
RJ-45 connectors are used for external communication to a remote computer or terminal.

WARNING!
All electrical work shall be implemented in accordance the relevant electrical installations
stipulated by local distribution network operator (DNO) and follow the important safety
instructions in this manual.
WARNING!
Under the DNO’s inspection authority a dedicated circuit breaker must be installed at the
connection to the AC mains.
WARNING!
Make sure the suitable connecting cables are used for both the AC and DC wirings. The
cable must be taken into consideration for its ampacity and weatherproof like temperature
fluctuation and UV radiation, etc. Use #10 AWG to #6 AWG, 90°C (194°F) copper wire for
all AC and DC wiring connections to the SE inverter.
WARNING!
PV arrays will be energized when exposed to light. Cover the arrays with opaque (dark)
material during installation and wiring.
