# Returns a system's last reported PV Power, Consumption Power, Battery Power and EVSE Power in Watts. Return’s operational mode for Battery, HP, and EVSE

`GET /api/v4/systems/{system_id}/latest_telemetry`

## Request

- Base URL: `https://api-qa2.enphaseenergy.com`
- URL: `https://api-qa2.enphaseenergy.com/api/v4/systems/{system_id}/latest_telemetry`
- Auth: none declared
- TypeScript: <https://skmtc.dev/enphase/apis/monitoring-api/docs/api/v4/systems/:system_id/latest_telemetry/get.ts> (a function with typed inputs; its response is checked against the schema)

Returns a system's last reported PV Power, Consumption Power, Storage meter Power, Battery Power and EVSE Power in Watts. Return's operational mode for Battery, HP, and EVSE. If the last_report_at is older than 7 days for a specific device, "last_report_at", "power" and "operational_mode" parameters will be returned in the response with the value as null.

PV + Storage sites will always be configured in Net Config. PV only sites can configured either as Net or Total config.

For PV only sites configured as Net config (load with solar), consumption power is calculated as: production + grid.

For PV only sites configured as Total config, consumption power provided as raw value measured by consumption CT (e.g. the home load).

For PV + Storage sites in Net config, consumption power is calculated as production + grid.
It does not include battery.

Consumption - battery = home load (e.g. fixed load)

battery is not considered fixed load, but can contribute to supplying the fixed load.

The consumption meter config is available in the /api/v4/system/{system_id}/devices endpoint. Refer to 'config_type' parameter.

HP Modes:

Mode_1 - Blocked Operation
Mode_2 - Normal Operation
Mode_3 - Power Consumption Recommended
Mode_4 - Power Consumption Enforced

EVSE Modes:

PLUGGED_OUT - EV Charger is not plugged in
IDLE - EV Charger is plugged in but, EV is not charging
CHARGING - EV Charger is plugged in and EV is charging
FAULTED - The EV Charger connector is faulted
SUSPENDED_EV - The charging session was suspended by the EV
SUSPENDED_EVSE - The charging session was suspended by the EV charger
UNAVAILABLE - EV charger is plugged in, but not authorized

## Path parameters
