What we build

Platform capabilities

The operator surfaces we build for storage and PV: energy flow, SOC/SOH, string diagnostics and alarms. The dashboard below is a deterministic simulator, not a live plant.

Real-time energy flow

Live single-line diagram showing power on every branch — PV array → inverters → AC bus → grid / load. Animation direction follows actual energy direction.

SOC / SOH analytics

Per-bank state of charge and state of health tracking. Battery cycle counts, thermal events and performance degradation trends surfaced in the dashboard.

String-level diagnostics

Performance ratio and health score for every DC string. Soiling, shading, connector faults and PID show up here long before they affect monthly yield.

Rule-based alarms

Configurable alarm rules over inverter, storage bank and POI telemetry. Critical / warning / info severity, time-stamped and source-attributed.

Protocol integration

Modbus TCP, IEC 61850, SunSpec and MQTT — direct polling or broker-based ingestion. Adapters for new inverter models added without core changes.

SCADA dashboard

Control-room view over battery storage banks, PV inverters and DC strings. Designed for operators managing multiple sites from one screen.

Live demo

Interactive BESS dashboard

A simulated hybrid plant: 11 MWh of storage across three banks, 18 PV inverters rated 100–125 kW and 90 DC strings. The simulated clock runs 120× faster than real time.

Interactive demo. Values come from a deterministic plant simulator, not from a live installation.

FAQ

BESS monitoring, in practice

Modbus TCP, IEC 61850, SunSpec and MQTT — polled or broker-ingested. New inverter adapters are added without changing the core platform.
Energy-flow topology across storage banks, PV inverters and DC strings, plus SOC/SOH analytics, string diagnostics, alarms and 24-hour power charts. An interactive demo runs on this site.
Yes. We typically sit beside the SCADA already in the control room and feed it, rather than replacing it. Alarms keep source attribution so operators know which device raised them.
Send inverter models, bank layout and the telemetry you already have. We return a 24h estimate within one business day.
