AlsoEnergy vs Solar-Log: Commercial Fleet Visibility
The Problem: Asset managers overseeing gigawatts of commercial and industrial (C&I) solar assets face a massive data aggregation problem. Inverters from SMA, Fronius, and Solectria speak different digital languages. The bottleneck is identifying a single underperforming string across a portfolio of 500 diverse rooftops without manually logging into 15 different OEM portals.
For enterprise-grade C&I portfolios, AlsoEnergy (now part of Stem) is the gold standard for hardware-agnostic fleet management. Its ability to ingest SCADA data, edge-device telemetry, and weather station feeds into a single 'PowerTrack' platform provides asset managers with the ultimate single pane of glass.

Lumen's Take
Scaling an O&M business requires eliminating the 'OEM Portal Tax'—the time your analysts spend jumping between SolarEdge, SMA, and Enphase portals. Solar-Log is a fantastic, highly reliable hardware datalogger with a solid portal, but AlsoEnergy's PowerTrack software is the de facto operating system for utility-scale and large C&I portfolios. You pay a premium for AlsoEnergy, but it's the only way to reliably manage a truly heterogeneous multi-megawatt fleet.
