Outlines of this chapter

This topic describes the DASS TECH inverter electrical connections. Read this part carefully

before connecting cables.

NOTE:

Before performing electrical connections, ensure that the DC switch is OFF.Since the stored

electrical charge remains in a capacitor long after the DC switch is turned OFF. So it's

necessary to wait for at least 5 minutes for the capacitor to be electrically discharged.

Installation and maintenance of inverter, must be operated by professional

electrical engineer.

Attention

PV modules generate electric energy before exposed to sunlight and can create

an electrical shock hazard. Therefore, before connecting DC input power cable,

cover PV modules using opaque cloth.

Danger

DASS TECH inverter has 2 MPP trackers, all PV modules connected to the same

MPPT should have similar rated electrical characteristics (including Isc, Voc, Im,

Vm, Pm and temperature coefficients), have the same number of series

connected PV modules and be all in the same orientation (azimuth and tilt

angle).

Note

4.1 Electrical connection

This topic describes the electrical connection process.

4.2 Connecting PGND Cables

Connect inverter to the grounding electrode using protection ground (PGND) cables for

grounding purposes.

4.3 Connecting AC Output Power Cables

Connect inverter to the AC power distribution frame (PDF) or electrical grid using AC output

power cables after obtaining approval from local electrical grid operator.

4.4 Connecting Communication Cables

This topic describes the functions of WIFI and RS485 ports and the method of connecting

WIFI and RS485 communication cables.

4.5 Connecting DC Input Power Cables

Connect inverter to PV arrays using DC input power cables.

4.6 Safety check

Before start the inverter, comply with the safety precautions and check AC、DC connections.
