Procedure
Sofar 30~40KTL is a three-phase output inverter, strictly comply with local grid-connection
requirements and safety standards.
Step 1
Open the cover
.
Figure4-5 Open the cover schematic diagram
Step 2
Remove the insulation layer of an appropriate length according to figure 4-6, then
insert the AC output cable though the PG waterproof cable gland.
Figure4-6 AC Output Cable schematic diagram
Context
All the AC output cables used for the inverters are outdoor five-core cables. To facilitate the
installation, use flexible cables . Table 4-1 lists the recommended specifications for the cables
and the breakers.
4.3 Connecting AC Output Power Cables
Connect the Sofar 30~40KTL to the AC power distribution frame (PDF) or electrical grid using
AC output power cables
.
The cross-section of the AC line conductor must be sized in order
to prevent unwanted disconnections of the inverter from the grid
due to high impedance of the line that connects the inverter to
the power supply point; In fact, if the impedance is too high, it
causes an increase in the AC voltage that, on reaching the limit set
by the country of installation, causes the inverter to switch off
Table4-2.

Caution
It is not allowed for several inverters to use the same circuit breaker.
It is not allowed to connect loads between inverter and circuit breaker.
Table4-1
Note: For the sake of safety, please make sure to use correctly sized cables, otherwise the current makes the cable overheat or
overload, even cause a fire.
Step 3
Connecting the AC output power cable: The AC output cable(R,S,T,N and PE) is
connected to the terminal block, as shown in figure 4-7
