GLOSSARY

Bluetooth*

Bluetooth

to communicate with each other. For Bluetooth communication, the Bluetooth devices do not need to be within sight of each other.

Electronic Solar Switch (ESS)

The Electronic Solar Switch is an optional available DC disconnection unit. If the inverter is equipped with an Electronic Solar Switch, the ESS must be securely inserted into the bottom of the inverter. The Electronic Solar Switch may only be removed by electrically qualified persons.

Energy

Energy is the power which a system can supply or consume within a certain time unit. Energy is measured in Wh

(watt hours). If, for instance, your inverter feeds in for half an hour at 3 000W and half an hour at 2 000W, it will have fed a total of 2 500Wh into the electricity grid.

Multi-function relay

The multi-function relay is an optional interface for managing a fault indicator or another external load. Depending on the parameters and measured values, the inverter determines when the connected load is switched on and off.

Power

Power is the product of voltage and electrical current strength. Power is measured in W (watts). The power shown in the display is an instantaneous value. It indicates the power your inverter is currently feeding into the electricity grid.

Danger to life due to high voltages in the inverter

Even when no external voltage is connected, there may still be high voltages present in the inverter.

• Do not open the inverter.

• Electrical installation, repair and retrofitting may only be carried out by a skilled person.

Risk of burns due to hot enclosure parts

• During operation, only touch the lower enclosure lid and the display.

Yield loss due to poor heat dissipation

• Do not place any objects on the enclosure.

CLEANING THE INVERTER

Damage to the display by use of cleaning agents

• If the inverter is dirty, clean the enclosure lid, the display and the LEDs using only clean water and a cloth.

DISPLAY

The display updates the measured values of your PV plant every five seconds.

You can operate the display by tapping it:

Single tap: to activate the backlight, to scroll to the next text line, to switch

between the power graph of the past 16 feed-in hours and the energy

yields of the past 16 days.

Double tap: the display alternates automatically between the firmware

version, the serial number of the inverter, the Bluetooth NetID, the

configured country data set and display language.

POWER AND YIELD CURVE

The power and energy of the inverter are displayed as diagrams. The daily power graph is displayed by default. The right-hand flashing bar of the diagram

represents the current hour. If the inverter does not feed any power to the electricity grid over a longer period of time (e.g. during the hours of darkness or if the PV modules are covered with snow), a gap is inserted into the chart. The bar for the current hour is updated automatically every five seconds.

After four seconds, the bar disappears for one second and then displays the current value.

By tapping on the enclosure lid, you can alternate between displays, and the graph will switch to show the energy yields of the last 16 days.

POWER DISPLAY

The power and energy of the inverter are displayed in the three fields: "Power", "Day" and "Total". The display is updated every five seconds.

The power that the inverter is currently feeding into the electricity grid.

The energy fed into the electricity grid on this particular day. This equals the energy generated from the inverter's start-up in the morning to the current time.

The total energy that the inverter has fed into the electricity grid during its entire operating time.

MEASUREMENT ACCURACY

The display values may deviate from the actual values and must not be used as a basis for invoicing. The inverter's measured values are required for the operational control and to control the current to be fed into the electricity grid.
