4. System Operation

Following the installation of all equipment and confirmation of all connections and terminations, system
commissioning should commence.

Initial Commissioning Procedure

 Turn OFF and lock out AC source to AC Combiner
 Turn OFF and lock out battery source
 Turn OFF all three of the XGI-1500 red on/off switches on the right side of the inverter
 Turn the disconnect handle on the AC combiner to the OFF position
 Remove DC De-Combiner cover and verify absence of voltage from all sources
 Verify all cabling in the DC De-Combiner is installed correctly and torqued appropriately
 Replace DC De-Combiner cover
 Remove AC Combiner cover and verify absence of voltage from all sources
 Verify all cabling in the AC Combiner is installed correctly and torqued appropriately
 Replace AC Combiner cover
 Open all three inverter covers, one by one
 Check for moisture on all internal surfaces. If moisture is found, remove all standing water and
condensation where accessible.
 Leave covers off and allow all condensation to be dried by the environment. Once fully dried,
wait at least an additional 1/2hr before re-installing covers.
 Close all three inverter covers
 Turn ON source of power to the AC combiner
 Turn the disconnect handle on the AC combiner to the ON position
 Turn ON all three of the XGI-1500 red on/off switches on the right side of the inverter, in any
order.
 Energize the battery, according to its instructions
 Using a laptop, log on to the network and confirm network access to inverters and PMC
controller. Please consult the PMC's manual on how to perform this step.
 Conduct a test run (charge/discharge) of the battery system
