Fronius monitoring, alongside the rest of your fleet.

Sol AI reads Fronius International systems and puts them in one list with every other brand you run, ranked by what each problem is costing. Solar.web gives installers a real fleet view of their Fronius systems. Sol AI is for the fleet where Fronius sits next to other brands: one list across all of them, each site checked nightly against its weather, each problem priced, and each case closed only when production proves the fix.

What Sol AI adds

  • Fronius sites in the same list as every other brand you run — 18 brands supported
  • Every night, each site checked against what it should have made in that day's weather — down to each string where the inverter reports them
  • Each problem priced in dollars a day, most expensive first
  • Each case kept open after the repair until the site's own production shows the fix worked
  • Owners' questions answered on WhatsApp from live plant data

Sol AI reads each system through the manufacturer's own cloud, with read-only access granted by the account holder. Nothing is installed on site, nothing is written back to the equipment, and the maker's own app keeps working exactly as before.

AI agents on your team

Four AI agents watching your Fronius sites — and the rest.

Onboarding agent

Starts watching a new site the day it's switched on.

The day a site comes online, the Onboarding agent starts reading it. By the end of the first week it knows what that site should make in its own weather.

Baseline ready — week one

Performance agent

Every night, checks every site and string against what it should have made.

Every night it compares every site against what it should have produced that day — down to each string (a row of panels wired together) where the inverter reports them. It prices each problem — “losing $28 a day” — and puts the most expensive first.

Losing $28 a day

Case agent

Owns each problem until the site proves it's producing again.

Each problem gets a case, and the Case agent keeps it open after the repair visit. It closes only when the site's own production shows the fix worked — “Fixed ✓ verified”.

Fixed ✓ verified

Customer agent

Answers the plant owner's questions on WhatsApp, 24/7.

It answers the owner's questions about their own system on WhatsApp, any hour, from live plant data, and sends alerts and reports on the same thread. Like an engineer on call for every plant, all day, every day.
