Growatt MAX 100-150KTL3-X2
Commercial PV inverter
Growatt publishes exact LV and MV ratings, eight MPPTs and RS485 or optional PLC hardware. The retained sources do not publish a firmware-matched third-party read map or establish the client/server role. Direct Edge compatibility remains unverified.

Compatibility
Direct Edge integration not yet verified
The exact-family manual and datasheets name RS485, USB and optional PLC or wireless accessories, but do not provide a firmware-matched third-party telemetry map and endpoint role.
MAX 100-125KTL3-X2 LV or MAX 124-150KTL3-X2 MV only. Record the full model, grid variant, firmware and communication accessory before requesting the matching interface specification.
Models
| Models | Interface | Route into Edge |
|---|---|---|
| MAX 100/110/120/125KTL3-X2 LV | 380 or 400 V class; eight MPPTs | Do not apply the 480 V MV electrical limits. |
| MAX 124/125/136/150KTL3-X2 MV | 480 V class; eight MPPTs | Record the exact rating and regional grid code. |
Specifications
The LV and MV groups use different AC voltage classes. The nameplate rating and suffix must be captured before applying electrical or monitoring assumptions.123
Interface
Documented measurements and integration boundaries for MAX 100-150KTL3-X2.
- 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
MAX 100-125KTL3-X2 LV or MAX 124-150KTL3-X2 MV only. Record the full model, grid variant, firmware and communication accessory before requesting the matching interface specification.
- InteroperabilityLimited
- Published interfaces exist, but the retained exact-family sources do not provide a complete third-party read contract.123
- AccuracyNot yet assessed
- No firmware-matched public map establishes the exact readable measurements, data types, scaling and unavailable-value behavior.123
- SecurityNot yet assessed
- The retained sources do not establish authentication, encryption or read-only privilege separation for a third-party client.123
- ReliabilityLimited
- Electrical and environmental limits are published, while communication recovery, stale data and concurrent-client behavior remain unverified.123
- RuggednessSupported with conditions
- The manufacturer publishes enclosure and operating limits; the installation must still meet those limits.123
Setup
-
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.
-
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.
-
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.
-
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.
