3.1 Identication

The Compact Station can be identied on the basis of the information provided on the type plate (see Section 3.4).

3.2 Safety installations

Overvoltage protection

The DC inputs of the inverters are tted with overvoltage protection type 2. We recommend an additional type 1 lightning protector for the PV generator (available as an option for single-tracking compact stations).

Over-current protection

The AC and DC circuit breakers of the inverters are equipped with thermo-magnetic overcurrent triggers.

Temperature limitation

For safety reasons the heat sink temperature of the inverters is limited to 85°C. At high ambient temperatures, the heat sink temperature may reach 80°C. In such cases, the maximum infeed power is temporarily reduced. The graphics display shows the corresponding status message. When the temperature rises to 85°C the corresponding power unit shuts down.

No. Description 1 Cable 2 Shrink sleeve 3 Cover spigot (part of system cover) 4 Clamping nut (part of system cover)

Note

 Any cable pass-through elements not used can be used as pressure-proof

reserve pass-through elements.

 Any cable pass-through elements that have been opened and are used as

reserve elements must always be tted with new covers (HSI 90-D).

 Any dismantled or damaged covers must not be re-used!

Procedure

1. Clean the sealing surfaces with a clean cloth.

2. Insert the system cover into the bayonet opening of the sealing gland and turn the system cover until it stops.

– If correctly tted, the marks should match up.

3. Tighten the red clamping nut up to the stop, either manually or using a exible socket-wrench.

4. Clean the cables and cover spigot with KR 60 cable cleaner (not included in the delivery package).

ATTENTION!

 Do not use any cleansing agent that contains solvent!

5. Slide the shrink sleeves on to the cables.

6. Pull the clean cables through the cable pass-through element and further to the connection points.

7. Connect the cables as described in Sections 5.2, 5.3, 5.5 and 5.6 (the cables must be fully installed and clamped for strain relief).

8. Use a centering aid (e.g. cloth or rubber strip) to hold the cable in the center of the cover spigot.

9. Slide the shrink sleeve on to the cover spigot.

10. Start the shrinking process at the cover spigot using a gas burner and low ame (shrink temperature approx. 20 ... 140°C).

– In the rst step, the shrink sleeve is pre-shrunk on to the cover spigot. This process

is completed when the hotmelt adhesive comes out.

11. Now let the shrink sleeve cool down for 10 ... 15 minutes.

12. Now proceed with the shrinking process on the cable. – The shrinking process is complete when the shrink sleeve makes close contact

with the cover spigot, without folds, and the hotmelt adhesive comes out all round.

The "Failure", "Error", and "Blocked" status messages, and the warnings, usually require certain measures to be taken by the qualied electrician in charge (see Section 8).

7.6.1 Booting

Status LED: ashes green

Status message Description

Irradiance too low The solar irradiation or rather the available output is too low for

mains operation.

Startup… Before connecting to the mains network, the Compact Station will

check the internal hardware and software components.

Restart delay The Compact Station has disconnected from the mains and is

delaying re-connection to the mains.

Idle The Compact Station does not start because at least one power

unit is unavailable for the MCU.

7.6. 2 Mains operation

Status LED: green

Status message Description

Mains operation The Compact Station has connected to the mains and is feeding in

to the mains.

Maximum power The Compact Station limits the fed output to the maximum

permissible output. Limitation of the output can occur when the PV generator has been over-sized or in the event of high irradiation.

Idc limitation The Compact Station limits the DC input current to the maximum

permissible value. This can occur where the design of the PV generator allows for the current in the MPP to be greater than the maximum permissible DC current of the system.

Iac limitation The Compact Station limits the in-fed mains current to the

maximum permissible value. This can occur in response to major uctuations in irradiation, low mains voltage, or due to an oversized PV generator.

Restart limitation The Compact Station increases the active power with a dened

progression (Pac progression and/or soft start) following completion of an external limitation.

Frequency limitation The Compact Station limits the fed-in active power owing to an

active frequency-dependent power reduction. External limitation The fed-in active power is limited via remote control. Remote control The Compact Station is remotely controlled by the solar plant

controller or a radio ripple control receiver.
