The ACS-500 system is a redundant, modular energy storage solution that can be AC coupled with other generators, such as PV or wind. The ACS-500 system comes mounted on a rack and pre-wired from the factory. The ACS-500 can input or output 500kW and absorb or supply 300kVAr in up to 40C ambient temperature, controlled through the pre-programmed Plant Master Controller.

PMC draws its supply power from a 346V/120V single phase transformer and is protected by a UPS, to be able to communicate with the ACS-500 system and the battery in case of a power outage. For more information consult the Heila Edge PMC manual and the Chapter on Communications.
RMA number from Yaskawa Solectria Solar and instructions for returning the unit. Placement and Anchoring To anchor the ACS-500 to a concrete pad, secure anchor bolts at the four anchoring provisions located at the ends of the horizontal support bars. These anchor points have an internal diameter opening of 1”...
Confirm that the AC switch on the XGI 1500 inverters (on the rack with other equipment in the ACS-500 AC-Coupled Storage system) are in the OFF position (Fig 4.1). Confirm there is no voltage at the terminals for the XGI 1500 inverters’ AC output conductors in the ACC1500-500 AC Combiner.

Aluminum oxidizes quickly when exposed to the atmosphere. An oxidized layer is a poor conductor that could lead to thermal issues, production loss, or damage to the De-Combiner. When using aluminum conductors on the AC or DC side of the ACS-500, follow these steps to prepare the conductors.
2. Use an appropriately rated sealant and seal the conduits fully to prevent the exchange of air between the conduit and the enclosure. Sealing the conduit will help prevent condensation in the enclosure. Yaskawa Solectria Solar DOCR-071070 Page 20 of 30...
Heila control cabinet. Install two separate Cat 6 Ethernet cables to the network switch inside this cabinet, one with access to the internet, one connecting to the battery management system. If the customer is providing their own PMC, call Yaskawa Solectria Solar for correct installation.
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 Yaskawa Solectria Solar DOCR-071070 Page 22 of 30...
System OFF Procedure To turn off the ACS-500, the following turn-off sequence is recommended, to avoid unnecessary wear of the components: Turn OFF all three of the XGI-1500 red on/off switches on the right side of an inverter, in any order.
