Future-Proof Commercial Solar Monitoring with Open, Revenue-Grade Data
Partner Overview
Mana Monitoring specializes in integrated energy monitoring for both solar generation and electrical load consumption across commercial and industrial (C&I) portfolios. Serving both new construction and retrofit projects, Mana delivers open, flexible monitoring architectures that give asset owners full data ownership, redundancy, and long-term scalability.

The Challenge
Commercial solar owners increasingly need revenue-grade accuracy, diagnostic insight, and regulatory-ready reporting, but traditional Data Acquisition Systems (DAS) often come with:
- $8,000–$12,000 in upfront hardware plus ongoing fees
- Vendor lock-in and limited future expandability
- Single points of failure
- Complex wiring and long installation timelines
Inverter-native platforms can be cost-effective, but they lack independent verification and financial-grade totals required for compliance, SREC reporting, and long-term asset management.
Mana Monitoring needed a solution that could deliver:
- Revenue-grade monitoring with redundancy
- Open data architecture
- Lower capital and operational costs
- Flexibility to scale into batteries, electrical load consumption, and future technologies
Why eGauge
Mana Monitoring selected eGauge Systems as the cornerstone of its hybrid monitoring architecture based on several key differentiators:
- Open data architecture supporting long-term flexibility
- Revenue-grade accuracy suitable for compliance and SREC reporting
- Ability to monitor solar production and electrical consumption in a single device
- Remote access and Modbus expandability
- Ease of installation and long-term value
- Responsive, knowledgeable technical support
The Solution: Hybrid API + Revenue-Grade Metering
Sonic Rooftop Solar Project Example
System Size: 750 kW DC / 561 kW AC
Inverters: 17 SolarEdge inverters
Modules: LG
Metering: eGauge Smart Meter
For the Sonic Rooftop commercial installation, Mana Monitoring implemented a hybrid monitoring architecture:
- SolarEdge inverter data is pulled directly via secure, real-time API—no additional hardware required
- An eGauge independently meters AC output at revenue-grade accuracy
- Both data streams are unified side-by-side in Mana’s monitoring platform
This approach delivers inverter-level diagnostics alongside financially auditable production totals—allowing instant cross-checks, validation, and outage detection.


Implementation & Adoption
Installation required:
- A single eGauge meter
- Zero Modbus wiring
- Minimal on-site labor
Mana’s team reported a smooth deployment supported by fast, responsive eGauge technical assistance. Internal teams were able to learn the system quickly and handle training in-house.
Primary users include:
- Asset managers
- Property managers

Results & Benefits
Since deploying eGauge-powered hybrid monitoring, Mana Monitoring and its clients have achieved:
- $8,000–$12,000 saved per project by reducing traditional, up-front DAS hardware fees and eliminating ongoing data access subscriptions
- Reduced ongoing capital and operational costs
- Faster identification of solar outages and underperformance
- Improved equipment maintenance through granular production data
- Dual-source reliability, eliminating single points of failure
- Full data ownership, free from vendor or manufacturer lock-in
- SREC and compliance reporting using the revenue-grade meter
Most importantly, operators can quickly identify underperforming assets and respond before issues impact revenue.
Future-Proof by Design
The hybrid architecture enabled by eGauge allows Mana Monitoring to seamlessly expand monitoring to:
- Battery Energy Storage Systems (BESS)
- Additional PV capacity
- Electrical load consumption via submetering
All without replacing existing infrastructure.
Partner Perspective
“eGauge has been excellent—we can faster identify solar outages and solar underperformance.”
Zoltan Milaskey, Mana Monitoring CEO
Conclusion
By combining eGauge’s revenue-grade, open monitoring platform with Mana Monitoring’s innovative API-driven architecture, commercial solar owners gain C&I-grade reliability at residential-level cost—without sacrificing data ownership, compliance, or future flexibility.
This partnership demonstrates how open systems and smart metering can redefine what’s possible in modern commercial energy monitoring.
