Introduction

WARNING

DC Switch

The DC Switch is both the main power switch and a protective component which is used to safely disconnect DC power between the PV array and the PV Inverter whenever necessary to do so.

The PV Inverter operates automatically (without the need of switching On or Off) when DC input and AC output requirements are continuously met. Turn the DC switch to the Off position only to stop PV Inverter operation when a ground fault condition is detected or when there is a non-ground fault condition to stop inverter operation such as maintenance and servicing.

ELECTRIC SHOCK HAZARD

• Do not perform maintenance and servicing without totally disconnecting

the DC source from the inverter. The DC switch does not de-energize the DC fuse circuits. The fuse circuits remain live even if the DC switch is turned to the Off position.

• To remove power to the inverter, disconnect power from the PV disconnect

device. See “Single Line Diagram for CL-60” on page xi.

• Alternatively, to remove power to the inverter, open all MC4 type connectors

using a special tool for disconnection.

Failure to follow these instructions can result in death or serious injury.

NOTE: For CL-60A, the DC switch is provided with a lockable twisting knob to

meet the NFPA 70E standard.

975-0768-01-01 Revision B 1–9

Introduction

Communication Interface Features a standard RS-485 port which can be connected with a monitoring device such as a power meter,

Protection Features The unit is equipped with the following features for preventing inverter damage, other equipment damage, and personal injury hazards.

• Short-circuit protection

• Ground insulation resistance detection

• Inverter output voltage monitoring

• Inverter output frequency detection

• Residual current protection

• DC injection of AC output current surveillance

• Anti-islanding protection

• Ambient temperature monitoring

• DC over-voltage protection

• Over-current protection

• Power module over-temperature protection

• Fan failure protection

• Arc fault detection and protection (for CL-60A)

Derating Feature

Output derating is a way to protect the inverter from overload or potential fault detections. These situations prompt the PV Inverter to initiate power derating:

• Altitude higher than 3000 meters

• Internal temperature is too high (including ambient temperature and internal components temperature)

NOTE: For example, installing the inverter in an enclosed space may hasten derating.

• Grid voltage is too low

• External power class adjustment

• Grid frequency is too high (see NOTE)

NOTE: Valid only when the country selected is DE or IT.

• High grid voltage with a simultaneous low PV voltage.

Power Limit Setting Inverter output power can be adjusted via the LCD Display or a remote grid dispatch from the utility company. The corresponding operating state will be displayed on the LCD screen.

Over-temperature Derating High ambient temperature, a blocked fan, or poor ventilation will initiate inverter power derating.

When the temperature inside the unit exceeds the upper limit, the inverter will derate its power output until the internal temperature drops within the allowable range.

Figure 1-9 Over-Temperature Derating

Grid Under-voltage Derating When grid voltage is low, the inverter will derate

the output power to make sure the output current is within the allowable range. Once the grid voltage is within Vmin (215V), the inverter will derate its output power.

Introduction

Output voltage max when PV voltage < 860

Output voltage max when PV voltage < 890

Output voltage max when PV voltage < 950

PV Over-voltage Derating The inverter regularly scans the PV voltage every 25 minutes and forces the PV to derate to test whether the maximum power point is less than 860 volts.

At 66 KVA, if the maximum power point is higher than 860 volts, then the inverter will return to the higher voltage limit before it starts derating.

Suppose that the lowest temperature is -25 °C, the open-circuit voltage of PV cells is

Grounding the Inverter

WARNING

ELECTRIC SHOCK HAZARD

Do not ground either DC positive or negative poles of the PV string. The Conext CL-60 PV Inverter does not isolate the PV from the grid.

Failure to follow these instructions can result in death or serious injury.

Grounding System Overview

In this PV system, all non-current carrying metal parts and device enclosure should be grounded (such as the PV array frame and the inverter enclosure).

When there is only one inverter in the PV system, the PE cable must be grounded.

When there are multiple inverters in the PV system, they can be grounded at multiple points. Connect the PE cables of all the inverters and the mounting metal frames of the PV array to the equipotential cable (depends on the situation at the site) in order to establish an equipotential connection.

Reactive Power Regulation

Pf Mode

Inverter provides reactive power regulation function. Use the Q-Var switch parameter to activate this function and select proper regulation mode.

Tab l e 5 -4 Explanation of Reactive Power Regulation Switch

Regulation Mode Explanation

The reactive power can be

regulated by the parameter PF (Power Factor).

The reactive power can be

regulated by the parameter Q-Var limits (in %).

The PF is limited to +1.000, and

Off

the “Q-Var limits” is limited to

0.0%.

Q(P)

Q(U)

The PF changes with the output power of the inverter.

The reactive power changes with the grid voltage.

The reactive power can be regulated by the parameter PF on the Run-param screen.
