# Adding, importing and merging systems

How sites get into the portal — vendor integrations, virtual systems, spreadsheet imports — and how to fix a site that arrived split or duplicated.

*Monitoring & Control → Fleet Management → PV Sites*

## Three ways a site gets into the portal

1.  **From a vendor integration.** Once your monitoring account is connected, its sites appear on their own and keep updating. This is the normal path and needs nothing on this page.
2.  **As a virtual system.** A site you maintain by hand, with no live feed — a legacy plant, a site whose portal has no API, or a placeholder for something under construction.
3.  **By import.** Readings brought in from a spreadsheet, either to backfill history or to keep a manually-read site current.

## Add Virtual System

The **+** button on the PV Sites toolbar opens the full system editor with the same seven tabs as System Settings. Only a few fields are required to save: **Display Name**, **Location**, **Installed Capacity DC** and **Vendor**. The *System Code* is generated for you.

It is worth completing more than the minimum before you leave:

-   **General** — timezone and coordinates, so daily boundaries and weather are right.
-   **Performance** — the twelve-month P-50 plan, otherwise the site has no expectation to be measured against and will never show a meaningful deviation.
-   **Financials** — income per kWh or a full model, otherwise the site contributes zero revenue.
-   **Alerts Management** — a virtual system with no live feed should usually have communication alerts left off.

Virtual systems can be hidden from the fleet list with Filter → General → *Hide Virtuals*, which is useful when you want to look only at metered reality.

## Importing data

The upload icon on the toolbar opens **Import systems data** for a bulk file; a single site can also be loaded from its own ⋮ menu with **Import Data**. Every import is recorded — **View Import History** on the same menu shows what was loaded and when, which is how you unpick a double-loaded month.

Before importing, check that the site's timezone is correct: timestamps are interpreted in the site's timezone, so an import into the wrong timezone lands production on the wrong days.

## Getting fresh data on demand

Three row actions cover the "this site looks stale" case:

-   **Sync System** — re-read the site from its vendor now.
-   **Sync Table Data** — refresh the values behind the list.
-   **Fetch History** — pull a longer historical window, used after a connection has been down or a site has just been connected.

All three are available in bulk from **Multiple Selection**, along with **Fetch Weather** and **Trigger weather-adjusted**.

## Merging and splitting

Vendors sometimes report one physical site as several systems, or a single system that is really two arrays under separate contracts. **Merge** in the row menu joins systems so the portal reports the physical site; splitting is handled by enSights support because it affects history.

The filter panel's General section exposes the results so you always know what you are looking at: *Include Splitted Systems*, *Include Merged Systems*, *Only Show Splitted Systems* and *Show Systems with Parent System*.

## Deleting and restoring

**Delete** removes a system from the fleet. Deleted systems can be brought back into view with Filter → General → *Show deleted systems*, but treat deletion as permanent and prefer *Suspend Alerts* or a tag for sites that are merely dormant.

## Common tasks

**Add a site that has no monitoring feed.** + → complete General, then Performance (P-50 plan) and Financials → Save. Import its monthly readings from the ⋮ menu.

**Backfill history for a newly connected site.** Row menu → *Fetch History*, then check the Analysis tab for gaps.

**Fix a site that appears twice.** Confirm both are the same physical site, then Merge. Check Import History first if one of them was created by an import.

## Common questions

**My new site shows no expected production.**  
The P-50 monthly plan is empty. Add it in System Settings → Performance.

**Can I undo an import?**  
Use *View Import History* to see what was loaded and contact support to reverse it. Do not re-import to "overwrite" without checking, as it can double the totals.

**Should a construction site be virtual?**  
A placeholder virtual system is fine, but suspend its alerts so it does not report communication faults for a site that is not built yet.
