Problem: Fragmented visibility
Every OEM has its own portal, so no one sees the whole portfolio.
PowerTrack: One system of record
See every site and device in one OEM-agnostic platform.
PowerTrack
PowerTrack unifies data, intelligent controls, and real-time insights in one integrated, edge-to-cloud solution. Backed by Stem’s end-to-end engineering expertise, it simplifies operations, maximizes asset performance, and drives greater value across solar, storage, and hybrid portfolios. You get cleaner data, faster commissioning, and full control of your portfolio.
The solution stack
Products are only part of the story. PowerTrack combines field-proven edge controls, cloud software, and Stem’s engineering and support teams into one solution, so each piece works better because it was built to work with the rest.

Signal in, insight out. Data comes directly off the device, is harmonized at the edge, and reaches the cloud ready for analysis.
Stem is agnostic at the SCADA layer. Depending on your requirements, Stem deploys its own SCADA or resells and implements a third-party platform.

Solution architecture
PowerTrack EMS sits at the center of every energy storage and hybrid site, connecting field equipment, the PPC, dispatch, and PowerTrack Cloud into one system. Select a site type to see how it fits together.


On solar-only sites, PowerTrack PPC and SCADA handle plant control. PowerTrack EMS can be added when storage comes later.

Portfolio dashboards, real-time PV, battery, and hybrid monitoring, remote configuration, lifetime analytics, and market dispatch automation.
Scheduling entity and edge market interfaces
Receives dispatch from the utility, ISO, TSO, or optimizer and returns unit telemetry.
PowerTrack EMS
Prioritizes setpoints and control modes and sends power commands to the PPC.
Closed-loop control at the point of interconnection.
EMS UI
On-site visualization, scheduling, and tuning.
Stores high-resolution site data on site.
Ignition-based SCADA for utilities or owners that require it.
Field equipment
PV modules and inverters, PCS, BESS, met station, and meters, plus the Stem Unit Controller, which passes PPC commands to the PCS and returns DC block and PCS telemetry.
Redundancy built in
Hot-standby EMS/PPC redundancy with automatic failover is available for every configuration.
SCADA, PPC, and EMS run real-time control that operators and lenders trust.
Built and tested by Stem before it reaches your site.
PowerTrack Sage
PowerTrack Sage turns PowerTrack data into plain-language answers and summaries, so your team spends less time digging through dashboards and more time fixing what matters.
“Site 14 underperformed by 30% yesterday. Inverters 3 and 7 faulted overnight and haven’t recovered. Replacement parts are in stock. Because the daily loss is larger than the cost of a visit, I recommend dispatching a technician today.”
Sage becomes more useful with every data type PowerTrack brings in, from telemetry today to contracts, maintenance records, and financial data over time.
