Operating Strategies
How the system earns its value.
Each strategy addresses a specific cost driver or reliability requirement. Most C&I sites benefit from combining two or more strategies within a single system.
Peak-Valley Arbitrage
Charge during low-tariff periods and discharge during peak-tariff hours. Reduces electricity purchase cost on time-of-use tariff structures. Requires tariff schedule data and metering integration.
All platforms
Demand Management
Limit peak demand drawn from the grid to reduce demand charges and protect transformer capacity. Particularly effective for sites with short but high load spikes. Requires real-time load monitoring.
All platforms
PV Self-Use Maximization
Store excess solar generation and consume it when PV output falls below site load. Reduces export to the grid and increases renewable self-consumption ratio. Requires PV-ESS platform or upstream PV integration.
PV-ESS platforms
Export Limitation
Prevent reverse power flow to the grid where grid codes or utility agreements restrict export. Storage absorbs excess PV generation that would otherwise be curtailed. Requires accurate metering at the grid connection point.
PV-ESS platforms
Transformer Protection
Limit current draw to protect an undersized or aging transformer from overload. Extends transformer life and defers capital expenditure on grid infrastructure upgrades. Requires transformer rating data and real-time monitoring.
All platforms
Backup-Enabled Configuration
Maintain power to critical loads during grid outages. Requires STS or equivalent switching capability -- confirm availability on selected platform. Off-grid or islanding operation requires additional engineering review.

Case Evidence
A C&I deployment from problem to result.
01 -- Load Problem
A mid-size manufacturing facility in Southeast Asia faced escalating demand charges due to compressed shift patterns creating sharp morning and afternoon load peaks. The site transformer was operating near capacity during peak periods, limiting production flexibility and creating grid stability concerns.
02 -- Selection Rationale
The 241 kWh air-cooled on-grid platform was selected for its capacity to address peak demand within the existing site footprint. Air cooling aligned with the covered installation environment. The 105 kW AC power output matched the calculated peak shaving requirement without oversizing.
03 -- System Configuration
One 241 kWh cabinet deployed behind the main transformer. BMS connected to site EMS for real-time load monitoring. Operating strategy: demand management with peak-valley arbitrage on time-of-use tariff. No PV input required at this stage.
04 -- Delivery
Cabinet delivered and commissioned within the agreed project timeline. Civil foundation and AC switchgear were prepared by the site EPC contractor in advance. Commissioning included BMS-EMS integration testing and operating strategy verification.
05 -- Operating Result
Peak demand drawn from the grid reduced within the first billing cycle. Demand charges decreased materially. Transformer loading remained within safe limits during all production shifts. The site operator confirmed the system performance aligned with the pre-project energy model.
