Supported Models and Sensor Availability¶

How Auto-Detection Works¶

When you add the integration, it attempts to identify your inverter automatically before asking you to choose a profile.

Auto-Detection Flow

Key points:

VPP-capable inverters (DTC present) are identified with high confidence
Legacy inverters (no DTC) use model name probing — works for MIN, MIC, SPH families
If auto-detection picks the wrong profile, delete and re-add the integration with manual selection
The Universal Register Scanner (Developer Tools → Actions) shows the detection reasoning in its output

VPP Protocol: Growatt's Virtual Power Plant Protocol (registers 30000+) enables advanced monitoring and control, and allows automatic model identification via Device Type Code. Models with "VPP + Legacy" fall back to the legacy register range (0–3999) if VPP registers don't respond.

Off-Grid Protocol: SPF inverters use registers 0–97 only. VPP registers are never attempted for these models.

Sensor Availability by Model¶

The MOD column below represents the MOD TL3-XH (hybrid, with battery). The grid-tied MOD TL3-X (no battery) is architecturally identical in the solar register range but its grid flow registers require a Growatt smart meter — see Smart Meter Requirement below.

Smart Meter Requirement¶

Several sensors only populate if a Growatt smart meter (GOSS-W or SPM-S CT clamp) is physically installed between the inverter and the grid connection. Without a meter the inverter has no way to measure AC import/export directly — the sensors appear in Home Assistant but always read zero.

Which sensors are affected¶

Sensor group	Without meter	With meter
Grid Export / Import Power	Always 0 W	Live reading
Power to Grid / Power to User (registers)	Always 0 W	Live reading
Energy to Grid Today / Total	Always 0 kWh	Accumulating
Load Energy Today / Total (register-based)	Always 0 kWh	Accumulating

house_consumption is never affected. It is a calculated sensor (solar_total_power + grid_import_power − grid_export_power) and always reflects actual consumption regardless of meter presence — it just falls back to being solar-only when grid readings are zero.

Which models are affected¶

Model	Meter required?
MOD 6000-15000TL3-X (grid-tied, no battery)	Yes — 3000+ register range returns all zeros without meter
MOD 6000-15000TL3-XH (hybrid)	Yes, for accurate grid registers; battery-side sensors unaffected
SPH-TL3, SPH, MIN TL-XH, WIT (hybrid)	Yes, for meter-based grid registers; calculated `house_consumption` always works
MIC, MIN TL-X, MID (grid-tied, no battery)	No — grid power is inferred from the inverter's own AC measurement
SPF (off-grid)	N/A — grid connection is AC input only, no export

What hardware to get¶

Growatt sell two compatible meters:

GOSS-W — DIN-rail energy meter with RS485, suited for residential panels
SPM-S — split-core CT clamp version, easier retrofitting without rewiring

The meter connects to the inverter's RS485 COM port (same bus as the Modbus adapter, or daisy-chained). Configuration is done via the Growatt inverter display or ShinePhone app — the integration does not configure the meter.

If you are unsure whether a meter is installed, check the Energy to Grid Today sensor at a time when you know the inverter is actively exporting. If it remains at 0 kWh while solar generation is high and house consumption is low, a meter is not present or not configured.

Power Flow Notes¶

Grid-Tied Models (MIC, MIN TL-X, MID)¶

No battery and no direct load measurement register. Power flow values are calculated:

house_consumption  = solar_total_power - grid_export_power + grid_import_power
self_consumption   = min(solar_total_power, house_consumption)
grid_export_power  = max(0,  power_to_grid)
grid_import_power  = max(0, -power_to_grid)

Hybrid Models (SPH, TL-XH, MOD, WIT)¶

Both calculated and register-based values are available. Register-based sensors (power_to_load, power_to_user, power_to_grid) are read directly from the inverter and are generally more accurate.

Battery power sign convention (all models):

Positive = Battery is charging
Negative = Battery is discharging

SPF off-grid inverters have hardware that reports the opposite polarity. The integration inverts this automatically — you always see the standard convention regardless of model.

Invert Grid Power¶

All models support an Invert Grid Power option to correct backwards CT clamp installations. When enabled, grid import and export values are swapped, and the sign of all grid power/energy sensors is flipped.

When to enable: If the Power Flow card shows export when you are actually importing, or vice versa.

How to enable: Integration → Configure → toggle Invert Grid Power.

Manual Model Selection Guide¶

If auto-detection fails (or you want to override), choose based on:

Phase: Single-phase or three-phase grid connection?
Battery: Do you have battery storage connected?
PV strings: How many separate solar array strings are connected?
Power range: Inverter nameplate rating

Hardware Connection¶

Adapter Options¶

Adapter	Interface	Settings
EW11	TCP/WiFi	TCP Server, 9600 baud, port 502
USR-W630	TCP/WiFi	Modbus TCP Gateway mode
USR-TCP232-410s	TCP	TCP Server, 9600 baud, port 502
Waveshare RS485-to-ETH	TCP	9600 8N1, port 502, RFC2217: On
Any RS485-to-USB	Serial	`/dev/ttyUSB0` or `COM3`, 9600 baud

Inverter Connector Pinout¶

Connector	RS485+ (A)	RS485− (B)
16-pin DRM/COM	Pin 3	Pin 4
4-pin COM	Pin 1	Pin 2
RJ45 (485-3)	Pin 5	Pin 1

If values look garbled or the connection is unstable, try swapping the A and B wires — adapter labelling is not always consistent with the inverter's convention.
