Is DYNVOLT a BESS EMS?+
Yes — DYNVOLT is the EMS (energy management system) for utility-scale battery storage, and it is also the optimization and trading layer that most standalone EMS products are missing. It sits exactly where every BESS needs an EMS: above the PCS, below the trading desk. It owns the dispatch decision, writes the active and reactive setpoints to the PCS over Modbus TCP / IEC 61850 / OPC-UA, enforces the warranty envelope, routes ancillary-service bids to the TSO platform, and never overrides the BMS safety layer. The difference from a generic EMS is co-optimization: DYNVOLT solves day-ahead arbitrage, intraday, aFRR, FCR, imbalance, and PV co-location in one model rather than as separate rules-based loops.
What is BESS optimization?+
BESS optimization is the dispatch software layer that decides — every minute, against live prices, forecasts, and constraints — which revenue stream a utility-scale battery should serve right now: day-ahead arbitrage, intraday, balancing reserves (aFRR / FCR / mFRR), imbalance settlement, or capacity markets. A serious optimizer co-optimizes across all of these simultaneously rather than running each as a separate rules-based loop, and prices every cycle against augmentation, calendar aging, and the warranty envelope so the engine never burns lifetime on a negative-margin trade.
What revenue streams does DYNVOLT optimize?+
Energy arbitrage (day-ahead and intraday continuous), FCR, aFRR, mFRR, capacity markets, imbalance settlement, and behind-the-meter peak shaving — co-optimized in a single dispatch model that respects state-of-charge, cycle budget, thermal envelope, and grid-code limits.
Is the optimizer cycle-cost aware?+
Yes. Augmentation cost, calendar aging, and the warranty envelope (cycle, thermal, and depth-of-discharge limits) feed into every dispatch decision so the optimizer never schedules a trade whose price spread fails to beat the cycle cost.
How is DYNVOLT different from a generic EMS or an arbitrage-only optimizer?+
A generic EMS dispatches against rules — it doesn't see prices or forecasts. An arbitrage-only optimizer captures day-ahead spreads but ignores balancing reserves, imbalance, and co-located solar. DYNVOLT solves the full revenue-stacking problem in one mixed-integer optimization, which is where the +30% revenue uplift versus arbitrage-only comes from.
Can it co-optimize with co-located solar?+
Yes — PV+BESS co-optimization is a first-class feature. Clipping recovery, ramp-rate compliance, curtailment hedging, and self-consumption are dispatched against a single envelope across PV and storage rather than as separate workflows.
Which BMS / EMS / PCS systems are supported?+
Sungrow, BYD, CATL, Tesla Megapack, Fluence, Wärtsilä, Powin, and Sineng natively. For anything else: IEC 61850 (MMS / GOOSE), OPC-UA, Modbus TCP, and Sunspec. The platform writes setpoints to the PCS — it does not replace the BMS.
How fast is the aFRR signal response?+
Bidirectional under 50 ms, with 99.2% availability on production deployments. The fast-loop control runs at the edge so the PCS receives setpoints on the millisecond cadence ENTSO-E requires for activated aFRR capacity.
Do you provide an audit trail for dispatch decisions?+
Every dispatch decision is logged with the price forecast, production forecast, state-of-charge, cycle-cost estimate, and grid-code constraints that drove it. Compliance teams, lenders, and warranty insurers can reconstruct any cycle on demand.
