SPS Annual Inspection checklist

Check condition of environment, and remove or create action to remove hazardous materials if any exist

Check condition of battery inverter including: secure termination of battery and AC cabling N / A / E; comms cabling; two wire auto start; glands secured so no points of entry for vermin or insects;

Check voltage of battery supply at battery inverter and at battery bank

Check DC wiring from Battery inverter, through DC isolator, to battery bank. Including terminals, general condition, entry points, mechanically secured

Update Firmware - battery inverter

Update Firmware - battery BMS

Check the fallback function, turn on the PV supplies. Unplug the RS485 lead (RJ45) in the SP PRO.<br>Check that each of the connected grid inverter’s output drops to zero after 10 seconds.

Confirm signage in place compliant with AS5139 / AS4509 / AS4777 including - ES, Isc (sum if multiple parallel banks), Voltage, Danger, relevant hazard signs, DC isolator, “battery” for cabling, shutdown procedure (adjacent to PCE), system location noted at Switchboard.

Confirm compliance with AS5139 checklist and note any exceptions

Site: clean, no debris on or under array

PV modules: DC isolators have good integrity; integrity of glands for isolator; no fractures, browning corrosion of panels; no moisture penetration of panels; Conduit has good mechanical integrity and fixings; integrity of glands for isolators

Wiring: good mechanical integrity; integrity of penetrations; integrity of earthing system; wiring secured to frame system and not lying on roof.

System tests results: Voltage Open Circuit; Isolation device operates correctly; Power production matches array size, orientation, tilt, weather and age of system;

Check mounting system: feet secure; rails secure; panels secure; wiring secured to array mounting structure where necessary.

Clean solar panels and remove any debris

Check Generating set operation (including automatic start and remote start and remote stop)

Check wiring and conduit and fixings to Generating set

Written notification to customer to have Generating set maintenance done by a qualified mechanic for oil, filter, operational parameters completed at least annually or after manufacturer specified running hours
