Rooftop solar monitoring
Monitor output and meet EVN grid rules — store data on-site, push on schedule.
Common challenges
Large grid-connected rooftop solar systems must send operating data to EVN and store it on-site for at least 7 days (Decision 378/EVN). When an inverter faults, the system looks 'fine' while the bill quietly rises. Logtek monitors output, current and voltage, alerts on yield drops, and meets the storage and data-push requirements.
- Inverter faults or silent yield drops the owner never notices
- EVN rules require ≥7 days on-site storage and periodic data push
- Per-brand inverter portals depend on the cloud, unreliable on weak networks
How Logtek helps
- Catch inverter faults and yield drops early to avoid losses
- On-site storage ≥7 days, ready to meet regulations
- Independent monitoring, not tied to the inverter vendor's app
- Instant alerts even when internet is intermittent
