# An EMS that runs at the edge, and thinks above it. > Myto EMS: edge control on a one-second cycle for solar, BESS, load, grid and EV charging — peak shaving, export limits, shadow-mode dispatch, audited control. Source: https://myto.energy/ems The Myto EMS reads every asset on site each second, keeps the site inside its limits, and executes the schedule the intelligence layer proposes. If the cloud link drops, the site keeps running safely on its own. 1-second control cycleVendor-neutralShadow mode by defaultAudited control What it controls ## Control modes, stated honestly. Each mode runs on the edge controller. The status next to it is the state it is in today, not the state we hope it will reach. AvailableBy design ModeWhat it doesStatus Peak shavingDischarges storage to hold site demand under a threshold, so the intervals that set the demand charge are covered.Available Self-consumption balancingKeeps solar serving site load first and uses storage to absorb and return the difference.Available Export limitHolds export at the point of interconnection inside the contracted or technical limit.Available Charging windowsDelayed and grid-optimised charging, so storage fills in cheap or surplus hours.Available Power and discharge limitsFixed active-power setpoints and total-discharge limits for commissioning, testing and contractual caps.Available Follow scheduleExecutes a schedule produced in the cloud, block by block, inside the local safety envelope.Available EV surplus chargingSteers charger power toward solar surplus through supported charger interfaces.Available Demand responseOpenADR 2.0b virtual end node, receiving demand-response signals.Available Hybrid plant controllerPoint-of-interconnection envelope for solar-plus-storage plants. First implementation; not certified for grid-code ride-through.By design Frequency and reserve servicesFirst-cut frequency response, secondary and tertiary reserve behaviours. Not NLDC-prequalified.By design Generator (DG) controlCoordinating diesel starts with storage and solar.By design Real-time operations ## The site, as the controller sees it. A conceptual single-line of one site through a simulated day. The controller's job is visible in the flows: solar to load first, surplus into storage, export held at the limit, storage released into the evening peak. A conceptual single-line diagram of solar, storage, grid, load and EV charging on one site bus. Simulated values · illustrative C&I site: 10 MWp solar, 4 MW / 16 MWh storage, 3 MW export limit · not a live dashboard Safe by construction ## Nothing moves until someone arms it. Optimisation that can write straight to a power conversion system is a liability. The EMS puts a gate between the decision and the plant. Available ### Shadow mode by default Schedules and setpoints are computed and recorded, but no physical write reaches the PCS until live control is explicitly armed. Available ### Audited arming Arming, disarming and every control action are written to an audit log with the user or process that issued them. Available ### Select-before-operate An optional two-step command pattern for sites that require it on manual control. Available ### Local fallback If the cloud schedule goes stale, the edge falls back to a local mode such as peak shaving or balancing, and buffers telemetry until the link returns.

Available ### Alarms and fault rules Rule-based fault detection at the edge, raised as alarms with the channel and threshold that tripped. Available ### Tariffs and billing Time-of-use tariffs, energy and billing aggregates by site, meter and category. Available ### Carbon accounting Carbon aggregates alongside energy and cost, from the same metered data. Available ### Schedule compliance pack 96-block state of charge and scheduled versus actual, exported as CSV or PDF. By design ### Learned anomaly detection Models that flag drift before a rule would. Rule-based detection ships today. By design ## See the EMS against your own site.
