DER fleet tally calculator
Add up a mixed fleet three ways: every rating, export-capable AC at the connection, and flexible load.
Read this first. The loaded values are invented placeholders, not real sites. Export assumes full PV output and full battery discharge at the same time, so it is an upper bound. Flexible load assumes chargers and loads are running and can be cut to zero. The 100 kW line is a test value, not a rule for any market. Numbers use a dot for decimals. A comma followed by exactly three digits is a thousands separator ("1,234" is 1234); any other comma is a decimal comma ("7,4" is 7.4).
Result
| Type | Sites | Every rating added (kW) | Export-capable (kW) | Flexible load (kW) | Export alone at or above the line? |
|---|---|---|---|---|---|
| Fleet | - | - | - | - | - |
Method per site: every rating added = PV kWp + battery kW + charger kW + controllable load kW. Export-capable = inverter AC kW, plus battery kW if the battery has its own inverter (AC-coupled), then capped at the export limit if one is set (0 means no limit). Flexible load = charger kW + controllable load kW. Fleet values are site values times the number of sites. Illustrative; not a design, a utility study or a market rule.
