Remote dispatch lets an outside controller, such as monitoring or SCADA software, set an inverter's active power, reactive power or power factor instead of using locally stored values. On CPS inverters, a control mode parameter picks between disabled dispatch, remote dispatch and local control. This applies to active power and to reactive power. On older CPS 100kW units, ActivePower and PowerFactor can be set from the LCD for local dispatch or through remote monitoring software for remote dispatch. Tesla's SCADA design manual uses cellular as the standard connection for diagnostics and dispatch, with VPN or jump server remote login as the alternative.

Claims

default_value

c1 drafted · lead nominal 0 UNITLESS

Scope: products CPS SCH350KTL-DO/US-800

Conditions: RemoteControlEn parameter, same default under the IEEE 1547-2018, Rule 21 and ISO-NE grid codes; 0 means dispatch mode disabled

review note: possible conflict with c9 (same source; check the conditions)

c3 drafted · lead nominal 0 UNITLESS

Scope: products Solectria PVI 50-60TL

Conditions: CTRMODE active power control mode (0 disable dispatch, 1 remote dispatch, 2 local control)

review note: support check: partial - Evidence shows CTRMODE default 0 but columns are unlabeled and the product/grid-code context is not explicit; the 0/1/2 meanings are stated.

c6 drafted · lead nominal 110 PERCENT

Scope: products CPS SCH350KTL-DO/US-800

Conditions: PSet remote electric dispatch active power setpoint, same under IEEE 1547-2018, Rule 21 and ISO-NE

review note: possible conflict with c8 (same source; check the conditions)

c2 drafted · lead 0–1 UNITLESS

Scope: products CPS SCH350KTL-DO/US-800

Conditions: RemoteControlEn parameter under the IEEE 1547-2018, Rule 21 and ISO-NE grid codes

c4 drafted · lead 0–2 UNITLESS

Scope: products Solectria PVI 50-60TL

Conditions: CTRMODE active power control mode (0 disable dispatch, 1 remote dispatch, 2 local control)

review note: support check: partial - Range 0 to 2 appears with the mode meanings, but the columns are unlabeled, so the min/max assignment is implied rather than stated.

requires

c10 drafted · lead Cellular data

Tesla SCADA design manual lists cellular as the standard remote connection for diagnostics and dispatch; VPN or jump server login is the alternative

review note: support check: partial - Cellular is listed as the standard connection for diagnostics and dispatch, but VPN or jump server is an alternative, so cellular is not strictly required.; review: partial - The passages list cellular as the standard connection for diagnostics and dispatch with VPN/jump server as an alternative, so 'requires' overstates it, though the note correctly mentions the alternative.

c11 drafted · lead Modbus

CPS inverters expose the remote dispatch enable and setpoints as Modbus registers

review note: support check: partial - Modbus-style registers exist for RemoteDispatchEn and setpoints, but the passages never name the Modbus protocol or say dispatch requires it.
