5 Using the Solar Installation PV150
5.1 Power On Solar PV150
To turn the PV150 on, press and hold the Rpe and uto buttons simultaneously.
5.2 Battery ondition heck
The PV150 automatically performs battery condition checks whilst idle and during
measurements. When the battery level is low, the battery symbol icon will appear on
the PV150 display. The PV150 will continue to function, however the batteries should
be replaced.
Note: When the battery symbol icon is flashing all tests will be inhibited and the
batteries must be replaced immediately as described in section 8.4.
5.3 Protective Earth Resistance (Rpe) Function
lways ensure that the circuit under test is electrically isolated.
If the test probes are connected to a voltage >5V, the measured voltage
will be displayed on the LCD. If the voltage exceeds 30V the Rpe
measurement function is inhibited.
5.3.1 Test lead resistance null
The PV150 can automatically compensate for the resistance of
the test leads using the following proceedure:
1. Hold the tips of the test probes firmly together as
shown, ensure a good electrical connection.
2. Press and hold the Rpe Null key (4).
3. The measured resistance of the test leads is shown in
the primary display until a beep is heard.
4. The Rpe display will now 0.00 and the Null icon is
illuminated
5. ll subsequent measurements will take into account
the test lead resistance compensation until the
function is disabled by pressing the Rpe Null key (4)
again.
Note: A maximum test lead resistance of 10 Ω
ΩΩ
Ω
ohms can be ta en into account. If the test
lead resistance is greater than 10 Ω
ΩΩ
Ω an error
beep will indicate that the lead Zero
function has failed.
Note: For ease of use, the PV150 will store the lead
compensation when switched off and recall
this value when next switched on. The stored
value is only applicable to the test leads used
when the compensation measurement was
made. If the test leads are replaced the Rpe
null function should be repeated using the
replacement test leads.

3. The resistance between the test probes is
displayed.
4. Press the Rpe key to terminate the continuous
measurement mode.
Note: Do not connect the PV150 to a voltage
source while performing the resistance
measurement as this will blow the fuse
located in the battery compartment.

5.4 Auto Sequence Measurement
Due to the high input impedance of the red 4mm test terminal, voltage
caused by leakage currents may be measured prior to starting a test.
Table 1
Viso
Pass / Fail Limit
250v 0.5 M ohms
500v 1.0 M ohms
1000v 1.0 M ohms
Note: During the insulation test, the PV150 applies a short circuit across the PV
string. The insulation test voltage is then applied between the RED 4mm
test lead and the two PV test terminals.
Note: If the DC voltage polarity is incorrect or the voltage is <5V or >1000V the
Auto Test will be disabled until the problem is corrected.
lways ensure that the circuit under test is electrically isolated from the
mains supply.
1. Connect the PV150 to the PV module as shown,
using the supplied test lead adaptors.
2. The red test probe should be connected to earth.
Where the structure/frame is bonded to earth, the
earth connection maybe to any suitable earth or to
the array frame.
3. Where the array frame is not bonded to earth, a
commissioning engineer may choose to do two
tests:
I. Between array cables and earth
II. Between array cables and frame
4. The PV150 will automatically detect any DC
voltage connected to the PV test socket inputs 8
and 9 and display the measured voltage.
5. If the PV voltage polarity is reversed, the polarity
indicator will flash a cross next to the voltage icon.
6. If the incoming voltage is >30v then the shock
hazard icon will flash.
7. Use the Viso button to select either the 250V, 500V
or 1000V insulation test voltage, please refer to
relevant standards for testing requirements.
8. Press the uto button and the Solar PV150 will
automatically perform the following tests:
Open Circuit Voltage
Short Circuit Current
Insulation Resistance
9. The measurement results will remain on the LCD
for 20 seconds or until a key is pressed.
10. tick or cross will be displayed next to the
insulation resistance measurement indicating
whether the result is above or below the threshold
values shown in Table 1.

5.5 Memory Store
The Solar PV150 can store up to 200 complete sets of measurements.
Press the Memory Store button to store all measured values on the display.
If there is sufficient memory space to store a set of readings, then the Store icon will
appear, and the readings will be stored in the next available memory location. If there is
insufficient memory space then the buzzer will sound. If there are no valid readings on
the display then nothing will be stored.
5.6 Memory Recall
Each press of the Recall button will increment the user memory location indicator and
display the measured values stored in that memory location. The location number is
shown on the bottom of the LCD display. fter the first press of Recall, the Store
button can be used to decrement the user memory location indicator to recall previous
memory location.
Press and hold the Recall button to download data to a PC via the USB port.
5% Variation warning.
If the recall data has a Voc or Isc reading, then the average of all the stored readings is
calculated. If the current recalled reading is more than 5% different from the average,
then the 5% warning icon will flash.
Average value
Keep pressing the Memory Recall button until the location number is 0. The display
now shows the average Voc and Isc. of all stored results.

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 PV150 and Survey 200R unit.
On the Survey 200R, press and hold the On/Off keys, keep both keys pressed.
On the PV150, press and hold the Rpe and uto keys, keep both buttons pressed.
The Survey 200R will now send its “Pairing” signal. When the PV150 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 PV150 has successfully paired, it will beep and display the serial number of
the Survey 200R. This should normally happen within a couple of seconds.
Note: The top line of the PV150 display will now show the W/m2 icon.
6.2 Un-Pairing from the Survey 200R
Make sure there are no other units operating nearby.
Turn the PV150 off.
On the PV150, press and hold the Rpe and uto keys, keep both buttons pressed for
about 10 seconds. The PV150 will then beep and clear its screen. The unit is now no
longer paired to any Survey 200R. Note that the top line of the LCD will display Rpe
ohms.
6.3 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 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 disabled. You must
remember to turn the Survey 200R off in order to save battery power.
6.4 Normal operation
When the PV150 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 PV150 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.

Solar Installation PV150 Operating Instructions
- 17 -
When an uto test is performed, the PV150 captures the irradiance, ambient
temperature and module temperature measurements from the Survey 200R. Press
Store and all these values will be stored along with any measurements made using by
the PV150.
6.5 Downloading data to P
Connect the PV150 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)
Click the Download button, and then press and hold the Recall key (6) on the PV150.
fter a few seconds the PV150 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 possible.
