3 Description
3.1 Identication
The inverter can be identied on the basis of the information provided on the nameplate
(see Section 3.5).
3.2 Functionality
Inverter operation is completely automatic and depends on the available output of the PV
generator. If there is enough power, the inverter starts mains operation and feeds into
the power grid. If there is not enough power available from the PV generator, the inverter
disconnects from the grid and shuts down.
The graphics display with three function keys allows convenient inverter operation and
reading of all important operating data. The graphics display is only switched on when the
DC input voltage is high enough.
The inverter has congurable functions for grid monitoring, limitation of output and reactive power control.
For the purpose of monitoring the PV power plant remotely, the inverter can be connected
directly to the Internet via Ethernet.
With the optional I/O module, the inverter can be remotely switched off and its output
controlled.
3.3 Safety installations
Overvoltage protection
P series SolarMax inverters feature integrated surge arrestors (varistors) at both input
and output. Each DC input (plus and minus connection) is tted with a surge arrester. The
surge arresters have a common gas discharge tube to ground. On the AC side a surge
arrester is installed between the phase and neutral. A second surge arrester with gas
discharge tube is tted between neutral and ground (for details regarding the tted surge
arresters see section 11).
When designing the PV system, it may be necessary to provide additional external lightning protection. The optional I/O module can be used to monitor external lightning protection modules.
Fault current monitoring
The inverters in the SolarMax P series have an integrated AC/DC-sensitive fault current
sensor. This sensor can distinguish between the operational capacitive stray currents
72
(caused by capacities of the PV modules to ground) and leakage currents (caused by
touching a pole of the PV generator). If the inverter detects an excess in the permissible
leakage or stray currents, it will disconnect from the grid.
Functions for current and power limitation
The inverters of the P series limit the DC feed-in current, the output power and the AC
output current.
Temperature limitation
At ambient temperatures of more than 45 °C the equipment temperature may reach more
than 80 °C. In such cases, the maximum in-feed power is temporarily reduced. When the
equipment temperature rises to over 85 °C, the inverter disconnects from the grid.

6.3 Auto-test
The auto-test (only available in the "Italy" country setting) checks the grid monitoring
of the inverter. The auto-test consists of 7 test steps in which the triggering behavior is
checked in the case that the voltage and frequency limits are exceeded.
In the auto-test, the respective limit value is successively changed until it reaches the
triggering threshold (i.e. the current reading). If the grid monitoring function is working,
the inverter triggers the grid monitoring. For each step of the test, the graphics display
shows the current reading, the trigger value, the trip time and the set limit. During the test
of the frequency limits, the activation status of the limit value is also displayed.

Temperature dependent output reduction
The inverter can feed 100 % of its rated output for an unlimited time up to an ambient
temperature of 45 °C. When operating in ambient temperatures in excess of 45 °C it is
possible that the yield is reduced. For this reason excessive ambient temperature should
be avoided. In the specied ambient temperature range the power output of the SM2000P
will be consistent.
