Why Integrations Matter

No Two BESS Sites
Are Identical

A grid-scale project in Rajasthan uses multiple cell manufacturers cells with Sungrow inverters and communicates with the SLDC over DNP3. A data center in Hyderabad runs BYD modules with SMA PCS and connects to the building management system over OPC-UA. A microgrid in the Northeast uses custom Indian BMS over CAN Bus with satellite backhaul over MQTT.

The EMS that runs all three sites must speak every protocol, understand every register map, and normalize every data format into a single coherent picture. That is what Ingro's integration layer does, it is the universal translator that lets Cloud EMS, Battery AI, and Battery Passport work with any hardware ecosystem.

The Problem

Vendor Lock-In Is
the #1 Risk in BESS

When your EMS only works with one BMS brand, one inverter model, or one communication protocol, you are trapped. Costs go up, options go down, and your BESS cannot evolve.

Hardware Tied to Software

Most EMS platforms only work with their own brand of BMS or inverter. When you need to expand capacity or replace failed modules, you are forced to buy from the same vendor, regardless of price or quality.

Proprietary Protocols

Closed communication protocols mean your BESS data is trapped in a single vendor's ecosystem. You cannot integrate with third-party analytics, trading platforms, or fleet management tools.

Upgrade Paralysis

When better, cheaper hardware becomes available, new LFP cells, more efficient PCS, smarter meters, a locked-in system cannot adopt it. Your BESS is frozen in time while the industry advances.

Ingro's Answer: Hardware Freedom

Our integration layer decouples your software from your hardware. Choose best-in-class components from any manufacturer, swap hardware when better options emerge, and future-proof your BESS investment. When you upgrade inverters or add new battery modules, the software adapts automatically.

Protocol Support

Seven Protocols.
Every Device.

From legacy serial Modbus to modern cloud APIs, Ingro speaks the language of every device in your BESS ecosystem.

Modbus TCP/RTU

The Workhorse

Connects to 90% of BMS, inverter, and meter hardware in the field. Ingro maintains custom register maps for every major manufacturer, so integration is plug-and-play rather than weeks of manual configuration.

  • TCP and RTU (serial RS-485) support
  • Pre-built register maps for All BESS manufacturers
  • Custom register mapping tool for proprietary BMS firmware
  • Multi-drop support for daisy-chained devices on a single bus

IEC 61850

Utility-Grade

The gold standard for grid-connected BESS. Required by most SLDCs and RLDCs for substation-level integration. Ingro supports MMS, GOOSE, and Sampled Values for full SCADA interoperability.

  • MMS (Manufacturing Message Specification) for SCADA data exchange
  • GOOSE messaging for sub-4ms protection signaling
  • Sampled Values (SV) for high-resolution waveform capture
  • ICD/SCD file generation for SLDC onboarding

DNP3

Distribution Automation

The protocol of choice for SLDC/RLDC communication across Indian distribution networks. Ingro supports Level 2 and Level 3 compliance for both outstation and master station roles.

  • Level 2 and Level 3 outstation compliance
  • Unsolicited response mode for real-time event reporting
  • Secure authentication (SA v5) for tamper-proof communication
  • Tested and certified with major Indian SLDC systems

OPC-UA

Modern Industrial IoT

The next-generation industrial protocol, secure, scalable, and firewall-friendly. Ideal for brownfield integration where the BESS sits alongside existing factory automation or building management systems.

  • Client and server mode for bidirectional data exchange
  • Built-in security: X.509 certificates, encrypted channels
  • Information modeling for structured, self-describing data
  • Firewall-friendly, works over standard HTTPS ports

REST / GraphQL APIs

Cloud-to-Cloud

For integration with the broader energy ecosystem, CPO platforms, energy trading systems, weather services, and third-party analytics dashboards. Webhooks for real-time event push.

  • RESTful endpoints for CRUD operations and telemetry queries
  • GraphQL for flexible, client-driven data fetching
  • Webhook subscriptions for real-time alarm and event notifications
  • OAuth 2.0 and API key authentication

MQTT

Lightweight IoT

Purpose-built for edge devices and remote microgrids with limited or intermittent connectivity. QoS levels ensure data delivery even over unreliable satellite or cellular links.

  • QoS 0/1/2 for guaranteed message delivery
  • Last Will and Testament for device disconnect detection
  • Retained messages for instant state sync on reconnect
  • TLS-encrypted broker connections with certificate pinning

CAN Bus

Cell-Level Access

Direct communication with battery management systems at the cell level. Bypasses high-level abstractions to extract raw voltage, temperature, and impedance data from individual cells.

  • CAN 2.0B and CAN FD support for high-throughput data
  • DBC file parsing for manufacturer-specific message decoding
  • Cell-level voltage and temperature at 1-second resolution
  • Critical for Battery AI health analytics and Battery Passport data

Architecture

Edge Intelligence. Cloud Scale.
Zero Gaps.

A four-layer architecture that collects data locally, abstracts hardware differences, enables hot-swappable drivers, and enforces defense-in-depth security.

Layer 1

Edge Gateway

An industrial-grade on-site PC running Ingro's edge software. It collects data from every field device, executes critical control loops with sub-second latency, and syncs with the cloud over encrypted channels.

  • Sub-100ms local control loop for safety-critical operations
  • Local data buffering, no data loss during connectivity drops
  • Automatic failover: edge takes full control if cloud is unreachable
  • Remote firmware updates with rollback capability
Layer 2

Protocol Abstraction Layer

Hardware-specific register maps, message formats, and data types are abstracted into a unified data model. Cloud EMS and Battery AI see the same clean data structure regardless of whether the source is any PCS over Modbus.

  • Unified data model: same API whether BMS is any global manufacturer or custom
  • Automatic unit conversion and scaling across manufacturers
  • Timestamp synchronization across devices with different clocks
  • Data quality scoring, flag stale, out-of-range, or missing values
Layer 3

Hot-Swappable Drivers

Adding support for new hardware does not require firmware updates or site visits. Load a driver configuration file, map registers to the unified model, and the new device is online in minutes.

  • JSON/YAML driver configuration, no compiled code changes
  • Live reload: new drivers activate without restarting the edge gateway
  • Driver versioning and rollback for safe updates
  • Community driver library growing with every deployment
Layer 4

Cybersecurity

Energy infrastructure demands defense-in-depth. Ingro's integration layer enforces strict security boundaries between IT and OT networks, with encryption, authentication, and access control at every layer.

  • TLS 1.3 encryption for all data in transit
  • X.509 certificate-based device authentication
  • Role-based access control (RBAC) for every API and command
  • Network segmentation between IT (cloud) and OT (field devices)
