Solar-inverter clouds as a third data source — charging sessions reconstructed from the home PV system, even without a smart wallbox.
Wallbox-capable inverters are detected automatically — the driver simply enters their manufacturer API credentials in the driver portal. First charging sessions appear in the Fleet API within 60 minutes.
id_tag = pv-<brand>reason = pv-native | pv-reconstructed
OCPP SetChargingProfilePipelet pulls charging data from three sources: OCPP wallboxes, OEM CarData (BMW · Tesla · Volvo · Audi · Ford), and since May 2026 also from the cloud APIs of solar-inverter manufacturers.
In practice: if a driver has an integrated wallbox attached to their own PV system (Enphase IQ EV Charger, Huawei Smart Charger, EcoFlow Power Charger, Sungrow iEnergyCharger), all that's needed is a sign-in at the manufacturer — a simple OAuth login for Enphase, an API key for the others. New since June 2026: native session import for the Enphase IQ EV Charger — Pipelet reads the charger's own pre-segmented charging history straight from the Enphase API (minute-accurate start/end times, energy from the charger meter, full history included on first import). For manufacturers without a session API, the reconstructor detects charges from the lifetime energy counter. Either way, a complete charging session lands in ``op_charging_sessions`` with markers ``id_tag = 'pv-<brand>'``, ``reason = 'pv-native'`` or ``'pv-reconstructed'`` and ``station_id = wallbox-serial``. Fleet managers and reimbursement workflows can recognise the PV source, reimburse it separately, or report it as the "solar share". Since June 2026, "PV Inverter" is selectable in the driver portal as the third data-source tile next to Wallbox and Digital Home Charging.
As of June 2026: nine manufacturers live (~68% market coverage) — Enphase, Solarwatt, SolarEdge, Fronius, SMA, Victron, Huawei FusionSolar, Sungrow iSolarCloud and EcoFlow PowerOcean. The reconstructor is brand-agnostic: a new manufacturer is three short files (adapter + worker branch + extractor). Solax and GoodWe (Phase 2) plus Kostal local (Phase 3) are on the roadmap.
The charger reports its own charging history: minute-accurate sessions straight from the Enphase API, full history included on first import. Validated in production — 45 historical sessions of a pilot customer ingested in a single pass.
Drivers pick "PV Inverter" as a peer of Wallbox and Digital Home Charging. The choice auto-enables the PV module and leads straight to coupling — Enphase via OAuth sign-in, seven more manufacturers via API key.
Enphase, Solarwatt, SolarEdge, Fronius, SMA, Victron, Huawei FusionSolar, Sungrow iSolarCloud, EcoFlow PowerOcean. The reconstructor state machine is the same for every brand — adding a new manufacturer is about one workday.
Every PV session carries ``id_tag = pv-<brand>``, ``reason = pv-reconstructed``, ``station_id = wallbox-serial``. Partner portals tell wallbox vs. solar at a glance — and which brand.
Enphase free tier (1000 calls/month) and Huawei Northbound (login throttle) are respected. Configurable per brand — paid tiers can poll denser.
Synthetic ``transaction_id`` is deterministic from ``(brand, system, start-edge-second)``. Reconstructor re-runs update the same session row instead of duplicating.
Driver picks their manufacturer in the driver portal, enters OAuth code (Enphase) or service credentials (Huawei, Sungrow, EcoFlow). No operator-side intervention needed.
Three files per brand (adapter, worker branch, extractor). Fully documented at dev.pipelet.com — brand X takes one workday to add.
A driver charges at home on their own PV system with an Enphase IQ EVSE — no OCPP wallbox. Pipelet polls the EVSE every 30 min, recognises sessions and feeds them into the reimbursement workflow.
Fleet manager sees per driver: 320 kWh OCPP wallbox + 142 kWh PV wallbox + 89 kWh public charging. The solar share can be reimbursed, subsidised or reported separately.
Instead of licensing an external aggregator, Pipelet talks to the manufacturer cloud directly. Aggregation value-add stays with the operator — no monthly per-driver fees to a third party.
A new manufacturer lands on the roadmap. Three files (adapter / worker branch / extractor) + i18n strings — done. State machine, UI badge, Fleet API surface come for free.
Wallbox-capable inverters are detected automatically — the driver simply enters their manufacturer API credentials in the driver portal. First charging sessions appear in the Fleet API within 60 minutes.
Home charging with three data sources — wallbox, CarData and PV inverter —, charging history and reimbursement: the EV-driver UI of the Pipelet suite.
Fleet management, driver management, RFID and billing for commercial EV fleets.
The new operator UI: sites, charger commands, vouchers, OCPI, billing.
