This article covers the first three. Fields marked **\*** are required, and nothing is committed until you press **Save**. ## General — identity and location ### Identity & Location - **System Code** — assigned by the portal, read-only. - **Display Name \*** — the name used everywhere. Keep a naming convention; this is what your team searches on. - **Location \*** — a place search. Choosing a place fills the coordinates. - **Timezone** — drives daily boundaries and alert windows. - **Coordinates** — latitude, longitude. These feed the weather and irradiance services, so precision matters for expected values. ### System Configuration - **Installed Capacity DC \*** and **Installed Capacity AC** — the DC array and the AC limit. The pair is what makes clipping visible, and DC capacity is what inverter comparisons are normalised by. - **Vendor \*** — the monitoring platform the data comes from. - **Type** — Residential, commercial and so on; used for grouping and benchmarking. - **Installation Date** — the anchor for degradation. - **Warranty Expires On**. - **System Reference ID** — the identifier on the vendor side, used to match the site to its source. - **Utility Contract / GATS System ID** — the identifier used for utility or certificate registries. ![System Settings — General](https://cdn-assets.productfruits.com/cb5e6c57-1ec3-4fae-a4c4-fa2cfa6741cf) ## Advanced — behaviour and data sources ### Behaviour - **Automated Cleaning System** — the site has robotic cleaning; also shown as an icon on the fleet list. - **Suspend Alerts** — stop alerting for this site. The right switch during a long outage or construction; remember to switch it back. - **Zero Export** — the site is not allowed to export, so export readings are treated accordingly. - **Allow Negative Power** — permit negative values instead of clamping them, which some meters need at night. - **Exclude from Benchmark** — keep an atypical site out of peer comparisons so it does not distort its neighbours. - **Exclude from SumSCADAInverters Job** — do not build the site total by summing inverters. - **Basic Revenue Calculation** — use the simple income-per-kWh calculation rather than the full financial model. ### Sensors & Data Sources - **On-site irradiance sensor (POA)** — the site has its own plane-of-array sensor. This is the preferred input for weather-adjusted expectations. - **Temperature External Service** — take temperature from a weather service rather than the site. - **External weather data** — *Off*, *Full Weather Data* or *GHI + Solar Radiation*. The on-screen note is the important part: *Full Weather Data overrides the on-site sensor POA with weather-service data. GHI + Solar Radiation keeps the on-site POA.* Choose Full Weather Data only when you do not trust the sensor. - **Weather Forecast** — enable forecast data for the site. ### Alert Settings - **Start Alerting At** / **Stop Alerting At** — the daily window in which alerts may fire. Defaults follow daylight; widen them for a site with unusual hours. - **Alerts Validation Window** — how long a condition must persist before it becomes an alert (for example one hour). Raising it is the standard cure for flapping alerts. - **Production Source** — *Inverter Production* or meter energy. This single setting decides which figure the Production column, the reports and the invoices use. ![System Settings — Advanced](https://cdn-assets.productfruits.com/e0ddc7f1-57c4-4b08-a029-527890ede3f4) ## Performance — what "expected" means ### P-50 Monthly Plan The twelve-month production plan. Enter the **Annual P-50 (kWh/kWp/year)** or the monthly production and PR figures; the page totals them and shows the system total and PR beneath. This plan is what every *Expected Production* and *Actual vs. Expected* number in the portal is measured against — including the weather-adjusted metrics, which take their monthly coefficient from here. ### Degradation **Yearly Degradation (%)**, **Second Year Degradation (%)** and the resulting **Degradation Adjusted** value. Together with the installation date they age the plan, so a ten-year-old site is not judged against its first-year expectation. ### Performance Parameters The physical model of the site, used for loss analysis and PR: **Inverters Capacity DC/AC**, **Panel Model**, **Tilt**, **Azimuth**, **Site Area**, and the loss factors — **Natural Soiling**, **Module Mismatch**, **Wiring Mismatch**, **String Mismatch**, **Module Quality Loss**, **LID**, **Inverter Efficiency**, **Inverter Auxiliaries**, **Inverter AC Ohmic**, **Inverter External XFM** and **Power Factor**. You do not need every field to get value from the portal — but the more of the model you complete, the more the loss waterfall and PR figures can attribute a shortfall to a cause rather than just reporting it. ![System Settings — Performance](https://cdn-assets.productfruits.com/0601a130-15a0-43ff-ab29-89e7948a31d5) ## Common tasks **Stop alert noise from a site under construction.** Advanced → *Suspend Alerts* on. Add a reminder to turn it off. **Switch billing to the new meter.** Advanced → *Production Source* → meter energy. For many sites at once, use the bulk action on the fleet list. **Fix expectations that are obviously wrong.** Performance → check the twelve monthly values and the units, save, then run *Recalculate Weather Adjusted* from the site's ⋮ menu. **Tame a flapping alert.** Advanced → raise *Alerts Validation Window* instead of switching the rule off. ## Common questions **Which setting should I check first when numbers look wrong?** Production Source, then the P-50 plan, then timezone and coordinates. Those four explain most surprises. **Will Full Weather Data improve my expected values?** Only if the on-site sensor is unreliable. It overrides the sensor entirely, which is a downgrade when the sensor is good. **I changed the plan but the site still shows the old expectation.** Save, then recalculate the weather-adjusted figures from the fleet list's row menu; historical values are not rebuilt automatically.
