Growatt MOD 3-10KTL3-XH

Residential hybrid PV inverter

Growatt VPP V2.03 explicitly lists MOD 3-10KTL3-XH in Annex 3-1 with equipment type 5400. It provides read-only identity, signed active power and grid frequency registers. Combine this public starting map with the exact-family port roles below and a local value comparison. Direct Edge installation remains untested.

Direct Edge integration not yet verified

The exact-family manual defines physical port roles; Growatt-authored VPP V2.03 defines Modbus RTU identity and telemetry for this model family. The actual endpoint and a local comparison remain installation tasks.

MOD 3-10KTL3-XH family only. Confirm the exact 3 to 10 kW rating, firmware, logger, meter, battery and regional grid settings before designing an integration. Do not transfer this claim to XH(BP) or XH2.

Specifications

The May 2024 manual covers MOD 3000 through 10KTL3-XH with two independent PV inputs. Battery-ready operation and export functions depend on the commissioned battery and meter arrangement.12

Interface

Documented measurements and integration boundaries for MOD 3-10KTL3-XH.

  • FC03 holding 30000: equipment type 5400; holding 30099: protocol version. FC04 input 31100/31101: signed active power at 0.1 W; input 31105: grid frequency at 0.01 Hz. Input 31000 supplies working state and 31005/31007 fault/alarm codes.
  • The COM connector has separate RS485A1/B1 parallel, A3/B3 meter, A2/B2 battery and A4/B4 SYN roles. Never treat the meter or battery pair as a general inverter telemetry bus.
  • Growatt's meter Modbus RTU description applies to its commissioned meter interface. Export limitation and storage operation depend on the meter and system configuration, not merely on an RS-485 connection.
  • No active-power, reactive-power, export-limit, battery-mode or grid-setting write is approved by this guide.

Assessment

MOD 3-10KTL3-XH with exact-family wiring and Growatt VPP V2.03 monitoring reads. Installed-site and native Edge acceptance have not been performed.

InteroperabilityLimited
The public VPP map names this family and documents Modbus RTU register functions, signed data types and scales; the actual shared-port topology remains site-specific.13
AccuracyNot yet assessed
VPP V2.03 defines active power, frequency, operating state and meter values with types and units. Compare inverter and grid-meter readings separately; site accuracy and freshness have not been measured.13
SecurityNot yet assessed
Client authentication, read-only privilege and network isolation are not specified for a third-party endpoint.1
ReliabilityNot yet assessed
The VPP map supplies working state and fault/alarm codes. Polling cadence, communication-loss detection and logger coexistence require the installed endpoint configuration.1
RuggednessSupported with conditions
The inverter is documented for installed residential PV use; site conditions and the exact unit still require review.12
ScalabilityNot yet assessed
Parallel operation is documented, but third-party poll capacity and multi-inverter client ownership are not.1
LifecycleSupported with conditions
An exact-family manual and product listing are available; any integration must still be checked against installed firmware and accessories.12

Setup

  1. Identify the installed variant

    Capture the complete XH nameplate, firmware, country setting and any battery, meter, logger or parallel-inverter hardware. XH(BP) and XH2 need their own evidence.

  2. Trace each communication role

    Map COM pins 3/4, 5/6, 7/8 and 17/18 to their commissioned parallel, meter, battery and SYN functions. Document the reserved logger port separately; do not move a lead to an apparently spare pair.

  3. Read identity, power and frequency

    Growatt VPP V2.03 (1 September 2025), Tables 2.1/2.2 and Annex 3-1, is the best-effort starting map. Use the installed serial address and baud rate with 8N1. FC03 holding address 30000 identifies the equipment type; 30099 identifies the protocol version (203 means V2.03). These are wire addresses: add one only if your client uses one-based register numbers. Read power with FC04 input address 31100, two words: PDU 04 79 7C 00 02, excluding slave address and CRC. Decode high-word-first signed INT32 and multiply by 0.1 W. Synthetic bytes 00 01 E2 40 give 12345.6 W; FF FF FF 9C give -10 W. The map defines positive active power as export and negative as import. Read frequency at input address 31105 as UINT16 × 0.01 Hz: 13 88 gives 50 Hz. Compare with simultaneous local monitoring before using the values.

  4. Keep control and measurement boundaries

    Use the commissioned meter for grid-point measurements and retain the existing protection and export-control design. Propose no third-party writes until a separate safety and controls review has been completed.

  5. Check the VPP endpoint configuration

    Use the commissioned inverter or logger endpoint. The protocol says VPP authority register 30100 must be enabled; have the installer confirm its existing configuration without exploratory writes. Keep occupied meter, battery, parallel and backup buses intact. This procedure supplies monitoring reads, not an Edge-tested import or permission to dispatch.

Common questions

Does the RS-485 COM socket mean Edge can read this inverter?
The published VPP map supplies a useful Modbus RTU starting point for this exact family. Use the visible read procedure and a commissioned endpoint; keep the separate meter, battery and backup pairs in their assigned roles. No Edge field-test result is claimed.13
Is the meter's Modbus RTU protocol an inverter register map?
No. The manual's Modbus RTU description is in the meter specifications. It cannot be reused to claim inverter telemetry or control addresses.1
Can this page be used to implement VPP export control?
No. This is an interface assessment with no approved Edge write path. Export limitation depends on a commissioned meter and engineered control configuration; flexibility dispatch also needs the plant's separate controls and market arrangements.1
