Your inverter tells you it is running.
Sol AI tells you what it is losing.
Sol AI connects to the inverters you already own, over their manufacturer APIs, and watches production at both site and string level. When something drops, it names the string, explains why, and puts a monthly cost on it. No gateway, no data logger, no site visit.
The problem with "everything looks fine"
Inverter apps are built to tell you the inverter is alive. They are not built to tell you the array is underperforming. Those are different questions, and only one of them costs you money quietly.
A green dashboard is not a healthy system
One string disconnects on a 29 kW residential system. The inverter is still running, so the app still shows green. The system is quietly 54 kWh a day short, and nobody finds out until the bill arrives.
Faults hide inside averages
At site level, a single failed string looks like a slightly cloudy week. Sol AI reads at string level, so the shape of the loss is visible instead of being averaged away.
A diagnosis you can act on
Every fault is classified with the money attached and written in a form the system owner can read, not just an error code for an engineer to interpret.
How it works
Four steps, none of which involve anyone visiting your roof.
You connect your existing inverter account
Sol AI authenticates against your manufacturer's cloud API using the account you already have. Nothing is installed on site.
It reads production roughly every 11 minutes
Each system is polled on a cadence set by what the manufacturer's API allows. Across the fleet the median gap between readings is about 11 minutes.
Actual output is compared against expected output
Production is assessed at plant and string level against what the system should be generating, so a shortfall shows up as a shortfall rather than as weather.
You get a diagnosis with a number on it
Not "fault detected" but which string, what is wrong with it, and what it is costing per month — in a form you can hand to whoever fixes it.

Questions
Does Sol AI need extra hardware installed on my site?
No. Sol AI connects to your inverter manufacturer's cloud API using your existing account. There is no gateway, no data logger and no site visit. If your inverter already reports to its own app, Sol AI can read it.
Which inverter brands does Sol AI support?
Sol AI supports 18 inverter brands, including SolarEdge, SMA, Fronius, CPS, GoodWe, Sungrow, Huawei, Fox, Solis, Growatt, SolaX, Solarman, SAJ and MaxPower.
How often does Sol AI read my system?
Roughly every 11 minutes. That is the median gap measured across 55,268 readings in the live fleet, and each system is read as often as its manufacturer's API allows.
My inverter app already shows everything is fine. What does Sol AI add?
Manufacturer apps generally report whether the inverter is running, not whether it is producing what it should. A single disconnected string on a 29 kW system can cost 54 kWh a day while the app still shows green. Sol AI compares actual output against what the system should be producing and flags the gap.
How much does Sol AI cost?
Sol AI is priced at $1.50–3 per home per month. That price point is what allows installers to build $15 to $25 monthly care plans on top of it. Larger fleets are quoted against the portfolio.
Can Sol AI monitor a utility-scale plant over Modbus or SCADA?
Sol AI reads each plant through its manufacturer's cloud, the same way it reads the rest of the fleet, with no equipment on site. If your plant needs a direct Modbus or SCADA connection, tell us about the site and we will talk it through.
Can Sol AI change settings on my inverter?
Sol AI only reads. Your inverter settings and controls stay exactly as they are.
