Battery Precautions
CAUTION The PVA-1500xx contains a small lithium battery and should not be disposed of with
general refuse. Dispose of the battery in accordance with all local codes and regulations
for products containing lithium batteries. Contact your local environmental control or
disposal agency for further details.
WARNING Only use the battery charger supplied by Solmetric.
Measuring High-Efficiency PV Modules
High-efficiency PV modules produce a short but intense inrush current at the start of the
I-V measurement. In extreme cases this inrush current can trigger the I-V Measurement
Unit's over-current protection circuit, causing the I-V Unit to internally disconnect from
the PV source circuit and temporarily enter the over-current "Disabled" mode. Also, the
I-V Unit can be damaged by severe overcurrent.
PVA-1000S Precautions
Using PV Connector Saver Jumpers
PV connectors, regardless of manufacturer, are not designed for large numbers of
connection/disconnection cycles. For this reason, the PVA-1000S is shipped with
connector-saver jumpers attached to its own PV connectors. The connector-saver jumpers
are intended to take wear and tear, greatly extending the life of the PV connectors on the
test leads and the PVA-1000S itself. Leave the connector-saver jumpers connected to the
PVA-100S’s primary PV leads at all times. Make all your PV circuit and test lead
connections/disconnections to the connector-saver jumpers, not to the PVA-1000S’s PV
connectors.
CAUTION When the lifetime of the connector-save jumpers has been reached (typically 100
connection/disconnection cycles), remove them, cut them in half to prevent further use,
and recycle them. Replace them with fresh connector-saver jumpers, which can be
ordered from Solmetric.
Using the connector-saver jumpers as described here will extend the life of the PVA-
1000S PV connectors by 100 times.
