8 Installation
Only skilled professionals with experience installing electrical systems should perform
installation of the SPOT. Persons installing the SPOT should be able to lift 50 lbs. without
assistance. At least 2 persons are required to install the SPOT.
Installation instructions should be followed exactly; improper installation of the
SPOT could void the warranty of the SPOT and any or all its component parts.
Thoroughly read any project specific setup or commissioning instructions from
Alencon Systems before beginning the installation.
If any instructions are unclear, or any additional information is required during the process,
please contact Alencon Systems LLC for assistance (see Appendix C).
8.1 Installation Criteria – PV
The following information should be considered when selecting the topology and the locations
for installation within the PV array.
PV strings exposed to sunlight represent a shock hazard at the wires and exposed
terminals. Disconnect PV strings while performing the installation to reduce the
risk of shock during the process. Test any wire or terminal for presence of high
voltage before touching them.
8.1.1 Voltage and Current Requirements
The string voltage at the power optimizer must never exceed its rated input voltage,
(i.e., 1000V for the SPOT 1000). Exposure to voltage higher than that may cause
damage to the SPOT and will void the warranty.
The SPOT will not deliver any power if the input voltage is below minimum specified input
voltage.
The short circuit current rating of the PV string must not exceed the rating of each input. Two
PV strings may be connected to a single SPOT input if the sum of currents from both PV strings
does not exceed the rating of each input.
The minimum voltage, maximum voltage and maximum current input ratings can be found on
the SPOT serial number label (see section 8.3).
