# Retrieves daily time-series telemetry data of the HP

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

## Request

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

Retrieves daily time-series telemetry data of the HP. The number of data points returned in the response corresponds to days spanned between the start_date and end_date parameter mentioned in the request.

## Path parameters

- `system_id` integer, required

## Query parameters

- `start_date` string
- `end_date` string

## Response `200`

Telemetry for the hp_lifetime

- object
  - `system_id` integer: The unique numeric ID of the system
  - `start_date` string: Start Date of the daily time-series data series
  - `end_date` string: End Date of the daily time-series data series
  - `consumption` integer[]: Energy units consumed per day (positive will correspond to energy consumption, negative will correspond to zero consumption). The time series includes one entry for each day from the start_date to the end_date with no gaps in the time series. If the response contains trailing zeroes, such as [909, 4970, 0, 0, 0], then there is no consumption by the HP
