2 Safety

2�1 Intended useThe SolarMax P series inverters are designed exclusively to convert the direct current generated by PV modules into alternating current which conforms to the parameters of the public grid. Any other use, in particular the conversion of direct current from batteries or other storage elements into alternating current is not permissible.

The inverters of the P series may only be connected to Class II PV generators.

2�2 Safety instructions

DANGER!Fatal electric shock hazard!In daylight the PV generator supplies the inverter with a dangerously high DC voltage.

■■ Make sure that all electrical feed-in lines to the inverter are de-energized before starting any work on the inverter or the feed-in lines.

DANGER!Fatal electric shock hazard!Components within the inverter are charged with a high voltage.

■■ Never open the inverter while it is in operation.

WARNING!Risk of injury from electric arc!Removing the DC connector when live can lead to dangerous electric arcs.

■■ Switch off the DC disconnector at the inverter before removing the DC connectors.

8

WARNING!A fire risk can result from inappropriate repair!

3 Description

3�1 IdentificationThe inverter can be identified on the basis of the information provided on the nameplate (see Section 3.5).

3�2 FunctionalityInverter 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 configurable functions for grid monitoring, limitation of output and reac-tive power control.

For the purpose of monitoring the PV power plant remotely, the inverter can be connected directly to the Internet via Ethernet.

The optional I/O module includes configurable interfaces for monitoring, remote control and the control of self-consumption of the inverter.

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 fitted 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 fitted between neutral and ground (for details regarding the fitted surge arresters see section 11).

When designing the PV system, it may be necessary to provide additional external light-ning protection. The optional I/O module can be used to monitor external lightning protec-tion modules.

10

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 (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.

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 specified ambient temperature range the power output of the SM2000P will be consistent.
