Description
Commissioning solar systems without hunting for home Wi-Fi passwords.
SAJ eManager-Promate is a plug-and-play smart communication gateway and data dongle featuring dual Wi-Fi and Bluetooth connectivity, engineered for rapid 3-minute mobile commissioning and 24/7 cloud telemetry on SAJ residential inverters.
Instant Tool-Free External Installation
Plugs directly into the inverter’s external communication port without opening electrical junction covers.
Dual Wi-Fi & Bluetooth (BLE) Modes
Bluetooth enables rapid local app commissioning without local Wi-Fi passwords, while Wi-Fi provides 24/7 cloud telemetry.
Automated Fault Alerts & Remote Firmware
Pushes real-time alerts to homeowners and allows installers to update firmware remotely from the office.
IP65 Heavy Weatherproof Enclosure
Matches the inverter’s outdoor protection rating, operating reliably across -30 °C to +60 °C temperatures.
More product details
Setting up Wi-Fi dongles on-site often fails due to weak router signals or customer password confusion. The eManager-Promate establishes an immediate local Bluetooth connection directly to the installer's phone.
- Direct Bluetooth Low Energy link allows configuring grid codes, battery types, and export limits in seconds.
- Eliminates on-site commissioning delays caused by poor residential Wi-Fi signal strength.
- Automatically scans for available 2.4 GHz domestic Wi-Fi networks for final cloud registration.

Continuous performance tracking with zero truck-roll firmware updates.
The gateway samples inverter metrics continuously, pushing generation and battery state-of-charge data to the eSolar cloud portal every few seconds. Real-time push notifications alert homeowners to utility grid outages or battery status changes. Enables remote installer parameter adjustment and batch firmware updates over-the-air (OTA). IP65 sealed enclosure certified for outdoor operation alongside wall-mounted hybrid inverters.
Pairs with host eManager communication hardware
The expansion brick works alongside host eManager controllers. Control signals integrate smoothly into the overarching energy management structure.
Includes project-specific engineering verification
Technical wiring documentation and terminal assignments are supplied with project quotations. System compatibility is confirmed before delivery.
Takes auxiliary sensing and plant control duties
Additional input and output channels link third-party hardware. Data routes directly through the primary management architecture.
Technical data
Seamless Wi-Fi and Bluetooth cloud connectivity engineered for SAJ residential solar and storage.
Plug-and-play communication gateway enabling 3-minute mobile commissioning.
Serving as the primary communication link for SAJ residential inverters (such as HS2 and H2 series), the eManager-Promate bridges inverter telemetry with the eSolar cloud platform. Its dual-mode Bluetooth and Wi-Fi architecture enables electricians to complete full on-site commissioning from a smartphone in under 3 minutes, followed by continuous 24/7 remote monitoring.

Does the eManager-Promate require an external power supply?
No. Powered directly from the inverter's internal DC bus. The dongle draws its low operating power (less than 2 W) directly through the inverter's external communication port, eliminating external 230 V power adapters or battery maintenance.
