## Applications

Energy Monitoring, IoT Energy Meter deployment, Energy Audit, EV Charging Metering, Solar & DER Monitoring, Energy Efficiency.

## Architecture

Titan sits between any electrical circuit and any data destination — cloud, BMS, or analytics platform. Inputs: distribution board, HVAC, EV charger, solar, BESS, pumps/compressors, specialised machinery. Outputs: Tech OVN Energy Intelligence Platform, Titan App, BMS/SCADA, third-party analytics.

## How Titan Compares

Built-in WiFi (typical: requires external gateway). Built-in Ethernet (typical: premium models only). Class 0.5S across the range (typical: 0.5S premium, 1.0 standard). MQTT native (typical: rarely). Harmonics to 31st per phase (typical: limited to 15th). Mobile commissioning via phone app (typical: laptop + proprietary software).

## https://www.techovn.com/products/titan-audit — Titan Audit Energy Logger

# Titan Audit — AC Current Logger, Voltage & Current Data Logger

Rapid-deployment energy logger with split-core CTs. Install in 2 minutes, no shutdown required. Same Class 0.5S metrology as Titan (IEC 62053-22).

## Two modes

Mode 1 — Full Energy Metering: Connect voltage leads to the load + clamp split-core CTs around phase cables. Measures V, I, P, energy, PF, harmonics — full parameter set.

Mode 2 — Current Logger (socket powered): Plug meter into any standard socket for auxiliary power; clamp CTs around cables you want to monitor. Measures current, calculates amperage profiles, tracks on/off cycles. Ideal for equipment runtime audits without voltage sensing.

## Nomenclature

Different teams call it different things — all describe the same hardware:
- Current logger / Current data logger
- AC current logger
- Voltage and current logger / Voltage and current data logger
- Electrical data logger
- Energy logger

Titan Audit is all of them.

## Install steps

1. Clamp split-core CTs around the conductors — no disconnection required.
2. Connect voltage leads to the load, or plug the meter into a nearby socket.
3. Open the Titan App on your smartphone and connect over WiFi.
4. The meter starts logging immediately — view live data from a safe distance.
5. When the audit is done, generate a PDF report from the app — or leave installed for continuous monitoring.

## Who it's for

- ESCOs & Energy Auditors — multi-site deployment, client-ready PDF reports, audit-to-M&V transition
- Facility Managers — in-house energy-waste identification
- Sustainability & ESG Teams — on-device CO₂ calculation for Scope 2
- Maintenance Technicians — 7-day equipment health checks

## Compliance

BEE PAT (India), ASHRAE Level 2/3 (US), ISO 50001 initial energy reviews, post-retrofit M&V.

## vs portable power loggers

Same deployment speed. Titan Audit stays installed for years; portable loggers are removed after the audit window. Same class 0.5S accuracy. Titan Audit has WiFi cloud connectivity + phone app PDF reports; portable loggers dump to SD card for desktop processing.

## https://www.techovn.com/products/titan-plus-btu — Titan Plus BTU

# Titan Plus BTU — Combined Electrical + Thermal Meter

Class 0.5S electrical meter + EN 1434 Class 2 BTU meter in a single DIN-rail device. Synchronous measurement on the same timebase — so chiller COP computed from the data is defensible.

## Why combined

COP = cooling kW (thermal) ÷ electrical kW. For the ratio to mean anything, both measurements must share a timebase. Separate meters from separate vendors with different clocks produce noisy, unreliable COP numbers. Titan Plus BTU timestamps both on the same chip.

## Integration

Flow sensor (ultrasonic for DN50+, electromagnetic for <DN50). Matched Pt500 temperature probes on supply and return. Electrical CTs on compressor + auxiliaries.

## Applications

- District cooling plants (tenant BTU billing + plant COP)
- Commercial chiller plants (continuous efficiency monitoring)
- Heat recovery systems
- Boiler efficiency

## https://www.techovn.com/solutions/energy-monitoring — Energy Monitoring System

Industrial energy monitoring system combining Titan smart meters with the Energy Intelligence Platform. Real-time circuit-level monitoring, consumption analytics, multi-site visibility, alerting, cost allocation, and CO₂ ESG reporting. Electricity tracking for factories & commercial buildings at circuit level.

## https://www.techovn.com/solutions/iot-energy-meter — IoT Energy Meter Solution

IoT energy meter with built-in WiFi and Ethernet — no gateway needed. Class 0.5S accuracy, MQTT + Modbus. Real-time remote energy monitoring for factories, buildings, and OEM integration. Replaces the traditional meter+gateway stack with a single connected device per measurement point.

## https://www.techovn.com/solutions/solar-monitoring — Solar Monitoring System

For net metering compliance, PPA verification, multi-site EPC portfolio management, BESS sizing from real data, solar+BESS efficiency tracking.

Why inverter portals aren't enough: inverters see DC input and AC output only. They miss grid import, DG runtime, and true self-consumption. Titan measures every source with utility-grade accuracy.

The Energy Intelligence Platform's renewable comparison engine produces: source-wise kWh/cost, blended cost of energy, self-consumption %, grid dependency %, DG runtime + fuel cost, source-mix charts, and BESS feasibility analysis.

## https://www.techovn.com/solutions/energy-efficiency — Energy Efficiency System

Reduce factory electricity cost. Six levers: demand management (peak shedding, load-slab alerts), power factor correction (per-circuit PF trending), phantom load elimination, schedule optimisation, motor/compressor degradation detection (harmonics + PF trending), post-retrofit M&V.
