5.1. AC connection
The Autarco inverter is equipped with an integrated Residual Current Protective Device (RCPD) and Residual
Current Operated Monitor (RCOM). The RCOM will detect the volume of the leakage current and compare it with
the expected value, if the leakage current exceeds the permitted range, the RCPD will disconnect the inverter
from the AC load.
If regulations in the country of installation stipulate an external residual current device, you must use a device
with a tripping threshold of 100 mA or more.
The AC cable used must be dimensioned in accordance with any local and national directives on cable dimensions
which specify requirements for the minimum conductor cross-section. Cable dimensioning factors are e.g.: nominal
AC current, type of cable, type of routing, cable bundling, ambient temperature and maximum specified line losses.
We recommend 4mm 105 ℃cable with resistance lower than 1.5 ohm.
Step 1: Slide the cable glad cap, cable gland body and adapter to the cable’
This inverter will be connected to a high voltage DC power generator and AC grid. The
installation must be performed by qualified personnel and in compliance with national and local
standards and regulations.
The AC connection to the electrical distribution grid must be performed only after receiving
authorization from the utility that operates the grid.
