SolaX X3-MEGA G2 40/50/60 kW

Compatibility

Direct Edge integration not yet verified

The official manual documents RS485-1 inverter networking and an internal Modbus parallel arrangement. It also names a meter on separate RS485-2 pins. The retained sources do not include a firmware-matched external point map, permissions, polling limits or a validated Edge import; a Pocket LAN or DataHub accessory is not proof of direct Modbus TCP on the inverter.

Confirm the exact X3-MGA-40K/50K/60K-G2 nameplate, country code, firmware, installed SolaX meter and any DataHub or Pocket dongle. Obtain an authorised read-only interface contract for that topology. Leave export limiting, reactive power, RRCR/DRM, remote settings and VPP dispatch with the commissioned controls owner.

Models

Specifications

SolaX's V3.3 sheet covers exactly 40, 50 and 60 kW European-voltage models in this guide. It gives 4, 5 and 6 MPPTs respectively, 32 A maximum input current per MPPT, up to 150% recommended PV array power, IP66 and Type II AC/DC surge protection. Country code and current certificates determine whether a particular installation is approved.²

Interface

Documented measurements and integration boundaries for X3-MEGA G2 40/50/60 kW.

• The manual's communication connector assigns RS485-1 pins 1/2 as A/B in and 4/5 as A/B out for inverter networking or a data collector. RS485-2 pins 7/8 are the A/B meter connection. These roles are explicit; a meter port should not be described as a spare northbound monitoring port.
• SolaX documents a DataHub parallel design of up to 60 inverters and a separate Modbus inverter-master design of up to 10. The manual requires the same firmware on all parallel inverters and says the RS485 cable must be less than 200 m for the DataHub arrangement. These are plant-control design conditions, not an Edge fleet capacity claim.
• The Modbus parallel example gives slave addresses 2–11 and a meter address of 1 at 9600 baud. These addresses are example settings for SolaX's internal master/slave arrangement, not a published third-party register map or an instruction to change a commissioned plant.
• The datasheet advertises built-in export power control, remote setting and night-time reactive-power compensation. Those functions depend on a correctly installed grid-point meter, utility approval and a commissioned control owner. A protocol or DI/DO terminal does not authorise external writes.
• The manual names optional Pocket WiFi, LAN and 4G monitoring dongles, but its RS485 connector and dongle uplink are distinct. Verify which device actually offers a supported external read path, firmware and access policy before planning integration.

Setup

1. Identify the European-voltage model

   Record the full X3-MGA-40K/50K/60K-G2 code, country code, firmware, grid approval and exact installed meter. The same manual also covers low-voltage variants that are outside this guide.

2. Map the existing plant control design

   Trace whether the site uses a SolaX DataHub, Modbus inverter master or individual Pocket monitoring dongles. Do not add a second master or change addresses on an operating export-control bus.

3. Keep inverter and meter terminals distinct

   Verify the installed connector before using RS485-1 pins 1/2 and 4/5 for the inverter network or RS485-2 pins 7/8 for the meter. Record termination, baud and existing addresses with the installer.

4. Get the authorised telemetry contract

   Obtain the model, firmware and accessory-matched third-party point list and access rules. Confirm register offsets, function, decode, units, timestamps and polling limits. Compare one read with SolaX's own view before scaling.

5. Review flexibility and export separately

   Verify the connection-point meter sign, CT orientation and controls owner. Keep export limits, reactive settings and utility dispatch on the approved controller until a separate safe control design is accepted.

Common questions

Are the meter and data-collector connections the same RS485 port?

No. The Version 13.0 terminal table assigns RS485-1 pins 1/2 and 4/5 to the inverter network or data collector, while RS485-2 pins 7/8 connect the meter. Preserve the commissioned wiring and verify the installed connector.³

Does a Pocket LAN dongle provide direct Modbus TCP for Edge?

The manual lists optional Pocket WiFi, LAN and 4G monitoring accessories, but it does not define a firmware-matched third-party TCP point service for this inverter. Obtain the exact accessory's authorised interface document before selecting a connection.³

Can the inverter's remote setting be used for VPP dispatch?

A datasheet capability does not grant third-party control rights. Export or reactive-power commands need the utility-approved grid-point measurement, site controller, permissions, fail-safe behaviour and separately reviewed commissioning plan.^2, 3
