INTRODUCTION
The Solar Utility Pro is a battery powered multi-function solar photovoltaic installation test instrument
capable of performing open circuit and short circuit tests required by IEC 62446 including:
Open circuit module string or array voltage
Voltage polarity
Short circuit module string or array current
1. USER NOTES
This instrument and its operating instructions are intended or use by adequately trained personnel.
Appropriate PPE should be worn at all times when using the Solar Utility Pro. Electrically insulated
gloves should be used when per orming tasks on live circuits above 50V. Arc- lash PPE selection should
be based on an incident energy analysis.
The following symbols are used in these operating instructions and on the Solar Utility Pro.
Warning o electrical danger!
Indicates instructions must be followed to avoid danger to persons.
Important, ollow the documentation!
This symbol indicates that the operating instructions must be adhered to in
order to avoid danger.
2. Sa ety Notes
In order to ensure safe operation of this instrument all notes and warnings in these instructions
must be observed at all times.
All test leads must be securely attached to the PV system under test. Always use the solar PV
connectors supplied or alligator clips to connect test leads to the PV system under test. Test
probes must not be used without alligator clips.
Never disconnect the test leads whilst any measurement is active. This may result in electrical
arcing and may damage the Solar Utility Pro.
Do not attempt to turn off the Solar Utility Pro while tests are active.
The Solar Utility Pro is intended for use in a dry environment only.
The PV test terminals maximum rating: 1500V DC open circuit voltage 40A short circuit current
45kW DC power. Do not exceed this rating. The DC supply must be isolated from earth/ground
during testing. See section 8.3 or maximum power ratings.
Never use a sharp tool in order to remove the batteries from the instrument always use the
supplied ribbon. Damaged batteries may lead to the battery becoming hazardous which may
cause a risk of fire.

SEAWARD SOLAR UTILITY PRO USER MANUAL
TESTED. TRUSTED… WORLD WIDE Page 5 of 19
Check the Solar Utility Pro and all associated cables and leads before operating the equipment.
Do not use if there are signs of damage. Only use the test leads supplied with the Solar Utility Pro.
Do not touch any exposed metal parts of the solar PV installation during testing.
Always ensure that the circuit under test is electrically isolated from all other external influences
such as the dc invertor before attempting a measurement.
Do not leave the Solar Utility Pro permanently connected to a PV installation. Always disconnect
all test leads immediately after use.
Before removing the Solar Utility Pro battery cover ensure that all test leads have been
disconnected from the instrument. Electric shock danger!
Do not operate the Solar Utility Pro without the battery cover securely in place.
Where safe operation of the Solar Utility Pro is no longer possible it should be immediately shut down and
secured to prevent accidental operation. It must be assumed that safe operation is no longer possible:
if the instrument or leads show visible signs of damage or
the instrument does not function or
onscreen messages warn against further use or
after long periods of storage under adverse environmental conditions.
If the Solar Utility Pro is being used to determine the presence or absence of hazardous voltages
always prove the operation of voltage measurement function before and after use by means of a
known voltage source or proving unit.
The Solar Utility Pro is not intended for continuous use. When the Solar Utility Pro is not being
used disconnect it from the system under test.
If the Solar Utility Pro is used in a manner not specified by this document then the protection
provided by the equipment may be impaired.
Do not open the instrument no user serviceable parts (apart from the batteries).
The lead sets supplied with the Solar Utility Pro can be used on 1500V systems that are isolated
from earth. Always ensure that the appropriate PPE is used when connecting and disconnecting
the lead sets.
Always use PROTECTED 18650 Li-ion batteries. Using UNPROTECTED 18650 Li-ion batteries could
lead to damaged batteries or damage within the Solar Utility Pro.

5.4 Voltage and Current Measurement
All test leads must be securely attached to the PV system under test. Always use the solar PV
connectors supplied or alligator clips to connect test leads to the PV system under test. In order
to reduce the risk of electrical arcing test probes without alligator clips should not be used. Only
use true MC4 connectors.
Never disconnect the test leads whilst any measurement is active. This may result in electrical
arcing and may damage the Solar Utility Pro
Always ensure that the circuit under test is electrically isolated from any mains supply.
Do not attempt to turn off the Solar Utility Pro while tests are active.
Connect the Solar Utility Pro securely to the PV module(s) or system as shown using the supplied test
leads.
The Solar Utility Pro will automatically detect any DC voltage connected to the PV test socket inputs and
display the measured voltage.
If the PV voltage polarity is reversed the polarity indicator will flash a cross next to the voltage icon.
If the incoming voltage is >30v then the shock hazard icon will flash.
Press the button and the Solar Utility Pro will automatically measure the short circuit current.
The measurement results will remain on the LCD for 20 seconds or until a key is pressed.
Note: If the DC vo tage po arity is incorrect or the vo tage is <5V or >1500V the Test key wi be disab ed unti
the prob em is corrected.

6. Use with the Solar Survey 200R
6.1 Pairing with the Survey 200R
Make sure there are no other units operating nearby.
Turn off both the Solar Utility Pro and Survey 200R unit.
On the Survey 200R press and hold the ON/OFF keys keep both keys pressed.
On the Solar Utility Pro press and hold the and keep both buttons pressed.
The Survey 200R will now send its “Pairing” signal. When the Solar Utility Pro detects this signal it will
remember the serial number of the Survey 200R and will look for that particular serial number in all
future communications.
When the Solar Utility Pro has successfully paired it will beep and display “connected”. This should
normally happen within a couple of seconds.
Note: The top ine of the So ar Uti ity Pro disp ay wi now show the W/m2 icon.
6.2 Put the Survey 200R into Transmit Mode
The Survey 200R can be put in and out of transmit mode by pressing and holding the temperature key
and then momentarily pressing the OK (Hold) key.
When in transmit mode there will be a flashing icon above the temperature key.
Note: When in transmit mode the auto shut down feature is disab ed. You must remember to turn the
Survey 200R off in order to save battery power.
6.3 Un-Pairing rom the Survey 200R
Make sure there are no other units operating nearby.
Turn the Solar Utility Pro off.
On the Solar Utility Pro press and hold the and keys keep both buttons pressed for about 10
seconds. The Solar Utility Pro will then beep and clear its screen. The unit is now no longer paired to any
Survey 200R. Note that the W/m2 on the top line of the LCD will display will no longer be displayed.

6.4 Normal Operation
When the Solar Utility Pro has been paired with a Survey 200R the top line of the display is used to show
the irradiance value measured by the Survey 200R.
The Survey 200R must be put into transmit mode as described above.
When the Solar Utility Pro is in range of the Survey 200R it will display the Survey 200R irradiance value
and display it on the top line of the LCD.
When an Auto test is performed the Solar Utility Pro captures the irradiance ambient temperature and
module temperature measurements from the Survey 200R. Press Save and all these values will be stored
along with any measurements made using by the Solar Utility Pro.
7. Trans erring Data to a PC
Connect the Solar Utility Pro to PC using the USB cable. (This will create a COM port on the PC).
Run the Seaward Solar Datalogger application on the PC. Select the correct COM port. (Use the Help
menu – Trouble shooting guide to help finding the correct COM port).
Press and hold the key on the Solar Utility Pro. After a few seconds the Solar Utility Pro will transfer all
its stored data to the PC.
By default the Datalogger application will save the data in CSV format. This can be opened using Microsoft
Excel. Note that each row of data will have the readings from the Survey 200R where applicable.
