Deye SUN-29.9-50K-SG01HP3-EU

Commercial hybrid PV inverter

Deye publishes RS485, RS232 and CAN alongside optional monitoring modules, battery BMS links, generator support and parallel operation. The retained sources do not establish a firmware-matched third-party read-only endpoint and map. Compatibility remains unverified.

Commercial hybrid PV inverter

Compatibility

Direct Edge integration not yet verified

The exact-family manual and datasheet document several communication ports used by batteries, meters, parallel inverters and monitoring modules, but no complete third-party read contract for the installed firmware.

SUN-29.9K, 30K, 35K, 40K or 50K-SG01HP3-EU-BM3/BM4 only. Record firmware, battery BMS, meter, generator, parallel and monitoring-module roles before requesting the matching telemetry specification.

ModelsInterfaceRoute into Edge
SUN-29.9/30/35K-SG01HP3-EU-BM3Three MPPTs and two high-voltage battery inputsKeep battery BMS and inverter telemetry roles distinct.
SUN-40/50K-SG01HP3-EU-BM4Four MPPTs and two high-voltage battery inputsRecord grid, load, generator and battery topology.

Specifications

The BM3 models use three MPPTs and the BM4 models use four. All combine conversion, battery charging, grid and load operation, so source identity must accompany every value.12

Model range
29.9, 30, 35, 40 and 50 kW three-phase variants12
PV inputs
Three MPPTs on BM3; four MPPTs on BM412
Published interfaces
RS485, RS232 and CAN; optional GPRS, Wi-Fi, Bluetooth, 4G or LAN monitoring12
Installation limits
IP65; -40 to +60 °C with derating above 45 °C12

Interface

Documented measurements and integration boundaries for SUN-29.9-50K-SG01HP3-EU.

  • Potential identity, production, state and alarm points require the exact firmware-matched manufacturer map before publication.
  • Every value must retain its source device and measurement boundary; inverter, meter, logger and controller values are not interchangeable.
  • No export-control, power-command, battery, generator, protection or grid-setting write is approved by this guide.

Assessment

SUN-29.9K, 30K, 35K, 40K or 50K-SG01HP3-EU-BM3/BM4 only. Record firmware, battery BMS, meter, generator, parallel and monitoring-module roles before requesting the matching telemetry specification.

InteroperabilityLimited
Published interfaces exist, but the retained exact-family sources do not provide a complete third-party read contract.12
AccuracyNot yet assessed
No firmware-matched public map establishes the exact readable measurements, data types, scaling and unavailable-value behavior.12
SecurityNot yet assessed
The retained sources do not establish authentication, encryption or read-only privilege separation for a third-party client.12
ReliabilityLimited
Electrical and environmental limits are published, while communication recovery, stale data and concurrent-client behavior remain unverified.12
RuggednessSupported with conditions
The manufacturer publishes enclosure and operating limits; the installation must still meet those limits.12
ScalabilityLimited
The vendor documents multi-device or plant operation, but third-party polling limits and coexistence behavior are not established.12
LifecycleSupported with conditions
Current exact-family documentation is available, but project delivery still needs the installed firmware and matching interface document.12

Setup

  1. Record the complete identity

    Photograph the nameplate and record the exact model, serial number, installed firmware and communication accessories. Do not select a point map from the family name alone.

  2. Map the commissioned topology

    Identify every inverter, logger, meter, protection relay and plant controller. Record the owner and physical source of each value before proposing integration.

  3. Obtain the missing interface contract

    Retain the firmware-matched manufacturer protocol document. Require the endpoint role, address model, data types, units, scaling, unavailable values and read permissions.

  4. Keep control outside this guide

    Do not propose active-power, reactive-power, export-limit, battery, generator, protection or grid-setting writes. Those functions need a separate engineered control and safety case.

Common questions

Does a published RS485 or Ethernet interface prove direct Edge compatibility?
No. A connector or protocol label does not establish the server role, firmware map, readable points, permissions or client coexistence rules.12
Can inverter values replace the point-of-connection meter?
No. Inverter telemetry describes conversion equipment. PCC control, protection, billing and settlement require their commissioned independent measurements.12
Does this guide support plant control?
No. It publishes no Edge write path. Export, active-power, reactive-power, battery, generator and protection functions remain with the commissioned control system.12
