Bankable intelligence
for every solar asset.

The ACE DLG80 is a high-performance multichannel data logger and IoT gateway engineered for the rigorous demands of solar resource and environmental monitoring. With 8 single-ended / 4 differential analog input channels and a 24-bit ADC, it connects seamlessly to irradiance sensors, temperature probes, wind instruments, and energy meters via 4–20 mA, 0–1 V, or resistive (PT100/PT1000) outputs.

Dual RS485 Modbus RTU ports allow simultaneous Master and Slave operation — polling inverters and MFM meters while forwarding aggregated data to local SCADA networks. The integrated LTE modem streams high-resolution data to Aeron's Live3 cloud platform for real-time PR and CUF analytics.

GPS time synchronization ensures every data point is precisely timestamped — essential for IEC 61724-1:2021 Class A compliance and bankable performance reporting.

Acquire

8 single-ended / 4 differential analog inputs at 24-bit resolution — GHI, module temp, ambient T+RH, wind speed and direction, soiling index, energy metering.

Process

GPS-synchronized timestamps, Modbus RTU master polling, and 1-minute averaging — all computed at the edge before transmission.

Store

8 GB micro-SD with over 5 years capacity at 1-minute intervals — local backup survives any LTE outage with zero data loss.

Output

Dual-stream: Modbus Slave to local SCADA + LTE to Aeron Live3 cloud — both outputs simultaneously, in real time.

Real-time solar intelligence

Multi-sensor analog input

Eight single-ended / four differential channels accept 4–20 mA, 0–1 V, PT100, and PT1000 inputs — all resolved at 24-bit precision.

GPS-synced edge processing

Built-in GPS receiver stamps every reading to UTC — ensuring IEC 61724-1:2021 Class A timestamp compliance with no NTP dependency.

Dual-stream output

RS485 Modbus Slave to SCADA and 4G LTE to Live3 run simultaneously — your local plant network and your cloud dashboard stay in sync.

Aeron Live3 — your solar plant's command centre.

The ACE DLG80 transmits encrypted data over 4G LTE directly to the Aeron Live3 cloud platform. Every parameter — GHI, module temperature, performance ratio, wind speed, CUF — is available in real time, from anywhere.

Historical datasets stored on the 8 GB micro-SD serve as local backup while the cloud aggregates multi-site data for portfolio-level analytics, alarm management, and compliance reporting.

IEC 61724-1:2021 Class A Compliance

Meets every requirement of IEC 61724-1:2021 Class A — the global benchmark for bankable solar energy monitoring data accepted by lenders and auditors.

24-bit ADC Resolution

24-bit ADC delivers 0.001 resolution and ±0.1% of full-scale accuracy — eliminating quantization error on all analog channels.

Advanced System Integration

Dual RS485 Modbus RTU (Master + Slave, isolated) — poll inverters and meters while simultaneously serving data to local SCADA and the Aeron Live3 cloud via 4G LTE.

Broad Sensor Compatibility

Accepts 4–20 mA, 0–1 V, 0–500 mV, PT100, and PT1000 inputs — compatible with virtually every pyranometer, temperature sensor, and environmental probe on the market.

GPS Time Synchronization

Onboard GPS receiver provides hardware-level UTC time sync — independent of internet connectivity, ensuring IEC-compliant timestamps even at off-grid sites.

Flexible Data Storage & Access

8 GB micro-SD stores 5+ years of 1-minute data. USB pen drive enables on-site retrieval — no network required.

Rugged IP65 Enclosure

PC/ABS UV-resistant housing rated IP65 — protects all electronics from dust, water, and UV exposure in outdoor installations.

Wide-Range Power Input

9–28 V DC input with reverse and over-voltage protection — runs directly from a solar panel and battery without AC supply.
