Installing and selecting an external RCD circuit breaker
Residual current device (RCD)
• Installations where local electrical codes require an RCD circuit breaker with a
lower leakage current rating may result in the external RCD circuit breaker being
accidentally tripped due to the discharge current. The following steps are
recommended to avoid unwanted tripping of the external RCD circuit breaker:

1. Selecting a suitable RCD circuit breaker is important for the correct operation
of the system. An RCD circuit breaker rated at 30mA
can trigger with a leakage current of 15mA (according to IEC 61008).
• In some countries an external RCD circuit breaker is required. The installer must

• All a-TroniX inverters are equipped with a certified internal residual current

2.3 Surge protection devices
(SPDs) for PV installation
WARNING!
Induced surges are the most likely cause of lightning damage in the majority of installations,
particularly in rural areas where power is typically supplied via long overhead power lines.
Surges can affect both the PV generator line and the AC cables leading to the building.
Lightning protection professionals should be consulted for final application. With suitable
external lightning protection, the impact of a direct lightning strike on a building can be
weakened in a controlled manner and the lightning current can be diverted into the ground.
The installation of SPDs to protect the inverter from mechanical damage and excessive
stress includes a surge arrester in the case of a building with an external lightning protection
system (LPS) when a separation distance is maintained. To protect the DC system, a surge
protection device (SPD Type2) should be installed at the end of the DC wiring of the inverter
and on the array between the inverter and the PV generator when the voltage protection
level (VP) of the surge arresters is greater than 1100V, an additional SPD type 3 is required
for overvoltage protection for electrical devices.
The formation of loops in the system must be avoided. This short routing and bundling
requirement includes all associated ground bundling conductors.
To protect the AC system, surge protective devices (SPD Type2) should be installed at the
main input point of the AC supply (at the load cutout), which is located between the inverter
and the meter/distribution system; SPD (test pulse D1) for signal line according to EN
61632-1. All DC lines should be laid as short as possible; plus and minus lines of the string or
the main DC supply should be bundled.
When installing the PV system, surge protection with surge arresters should be
provided. The grid-connected inverter is not equipped with SPDs on either the PV input side
or the grid side.
Spark gap devices are not suitable for use in DC circuits once they are conductive; they only
stop conducting when the voltage across their terminals is typically below 30 volts.
Lightning causes damage either from a direct strike or from surges due to a nearby strike.

alternating current and store energy in the battery. The inverter can be used to
optimize self-consumption, to store in the battery for later use or to feed into the
public grid. The working mode depends on the PV energy and user's preferences.

Working mode
3.2 Dimensions
If there is no PV feed-in, the battery first discharges for local
loads. The battery is charged when an excess of electricity
from other generation sources is detected.
Priority: Load > Battery >
Grid The energy generated by the PV system is used to
optimize self-consumption. The excess energy is used to
charge the batteries and then exported to the grid.
Working mode description
When the grid is off, the system supplies emergency power from
the PV system or battery to power the loads in the house (the
battery is required in EPS mode).
Priority: Load > Grid > Battery
In the case of the external generator, the electricity generated is
first used to supply local consumers and then fed into the public
grid. The battery is charged with the redundant current.

modules:
Please ensure that they are of the same type, have the same performance and
specifications, are oriented identically and are tilted at the same angle. To save cables
and reduce DC losses, we recommend installing the inverter as close to the PV
modules as possible.
Please choose a suitable external DC switch if the inverter does not have a built-in
DC switch.
• The voltage of the PV modules is very high and is in a dangerous voltage range.
Please observe the electrical safety rules when connecting.
• Please do not connect PV positive or negative to ground!

Step 1: PV string connection
The AX 1ph series inverters can be connected to 2 strings of PV
modules. Please choose suitable PV modules with high reliability
and quality. The open circuit voltage of the connected module array
should be less than 600V, and the operating voltage should be
within the MPPT voltage range.
