Nnergix Sentinel Solar review
Solar-focused PV monitoring with free access and paid plans from €540 per year.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Nnergix Sentinel Solar is a cloud platform for photovoltaic installers, engineering firms, electrical companies, and operators managing solar self-consumption systems. It gathers and standardizes data from inverter, battery, and meter manufacturers without requiring new hardware. Monitoring, reporting, alerts, and incident tracking make it relevant to teams that need operational visibility across PV systems, while its solar focus makes it less suited to buyers seeking broad grid or market analytics.
The published plans show a free Open option for monitoring up to 10 PV systems and a separate Open offer with a free 30-day trial for five systems, including alerts, reporting, and one user. Installers costs €540 per year and covers 20 systems, up to five integrations, alerts, reporting, and email support. Utility is €2,800 per year for 100 systems, unlimited integrations, phone support, and API access, alongside alerts and reporting. The different Open descriptions distinguish ongoing free access from a time-limited trial. Buyers should compare system limits and integrations against their portfolio before choosing a tier.
Sentinel Solar combines real-time and historical analysis with performance calculations, tariff-based savings estimates, customizable reporting, and production forecasts up to five days ahead using weather conditions. It can flag anomalous performance or zero generation and track incidents. Integrations include Fronius, SMA, Enphase, Huawei, SolarEdge, and others; web, iOS, Android, and API access support different operating contexts. Energy-community management and user roles extend its scope beyond single-system monitoring. Choose it for solar portfolio monitoring and reporting; teams needing broad grid or market analysis should look elsewhere.
