With Entec Solar’s goal of creating hardware tools

to facilitate people’s work, the E-1000 curve tracer

has been developed. The E-1000 I-V curve tracer

has been developed in collaboration with QPV

(www.qpv.es), a company specialized in audits and

quality control of large photovoltaic plants, which

has exposed the current needs in the measurement

of I-V curves in the eld. The union of Entec’s

hardware development experience and QPV’s I-V

curve measurement expertise has resulted in the

fastest and most innovative I-V curve tracer on the

market, all with an umatched measurement precision.

This high precision instrument allows the

measurement of up to 200 I-V curves per working

hour, either of photovoltaic modules or strings of

up to 1000V and 20A. It also incorporates several

new elements such as: a barcode reader for the

automatic identication of the module under test

and its position in the installation, an automatic

report generation tool to reduce processing time,

an automatic measurement option for hands-free

panel measurement, a wireless sensor (E-Sens)

with a communication range of up to 2km to

measure irradiance and temperature conditions, an

application for a mobile phone to control the device

remotely , and many more options that will change

the way you carry out your I-V curve measurements.

In addition, through a WiFi connection, the E-1000

is synchronized with the PVET® servers (www.pvet.

es), facilitating the post-processing of measurement

campaigns, storing all historical measurements, and

allowing intercomparisons and data cross-checking

for optimum fault diagnosis in your plants.

Thank you for purchasing the

E-1000 I-V tracer

1. Warnings

The E-1000 is an I-V curve tracer designed to work

with voltages of up to 1,000 VDC, which can be

hazardous to humans. That is why the E-1000 and its

accessories should only be used with the components

supplied by Entec Solar. Before using the E-1000, read

this manual in its entirety and pay special attention to

the points related to electrical safety and the points

highlighted by the warning and risk of electric shock

symbols (see section 1.2).

The use of unapproved accessories can affect the

safety of this device and can cause considerable

damage to equipment or people. The E-1000 should

be used only by personnel trained in low voltage

electrical installations and preferably with specic

trainingin photovoltaicsolarenergyinstallations.Entec

Solar will not assume any responsibility for damages

caused due to misuse of the device or its associated

components. The E-1000 and its components must

not be manipulated, modied, opened, or repaired by

any personnel other than those of Entec Solar. Any

tempering of the device by third-party personnel

may result in loss of equipment warranty. In case

the E-1000 or any of its associated accessories or

components need repair or re-calibration, please

contact Entec Solar or any of its distributors.

1.1 Symbols

• Continuous or reinforced double insulation

(protection class II)

• Danger warning! Consult documentation! Appears

in front of important instructions to prevent harming

people and equipment.

• Refer to the documentation that comes with the

device.

• Warning, high voltage, high fatality risk.

• The measurement devices should not be disposed

of in the domestic trash bins.

1.2 Device safety

The E-1000 has been designed and manufactured

following the regulation EN61010-1:2011: “Safety

regulations for electrical devices for measurement,

control and laboratory use.” Under these standards,

the E-1000 has been certied by an independent

laboratory and has been approved as insulated

reinforced CAT II 1000V DC device.

To ensure the security with which the device

has been designed, the following rules must be

scrupulously observed:

- Before using the device, read the entire manual

carefully and pay special attention to the points

related to electrical safety.

- Use the device only for measurements in

photovoltaic installations. Other sources of

current or voltage that are not of photovoltaic

origin can damage or destroy the instrument.

- Disconnect the PV circuit under test from any

other circuit to which it is connected to during

normal operation (i.e. inverter, charge controller,

battery, etc.)

- Before carrying out the measurements, make

sure that they do not exceed the operating limits

of the device: 1,000V and 20A. Exceeding these

limits could cause irreparable damage.

- The device must be used only by personnel

trained in low voltage electrical installations and

must have been previously trained for the use of

this specic device.

- During measurements, use the recommended

personal protective equipment (PPE): insulating

gloves, safety boots, face shield, etc.

- Never disconnect the device cables while a

measurement is being made. This could cause an

electric arc and cause damage to the device and

people.

- Avoid contact with the photovoltaic circuit

under test and with any other metallic object in

the vicinity.

- Avoid exposing the device to direct sunlight.

- Do not carry out measurements in humid

environments or in the event of rain and make

sure that no liquid enters the device.

- Do not carry out measurements in environments

with presence of gas or explosive, combustible

materials or in dusty environments.

- Use only the original Entec Solar accessories.
