Description
Eliminating Wi-Fi dropouts with hardwired Ethernet connectivity.
SAJ eSolar AIO3 is an All-in-One triple-link communication gateway combining Wi-Fi, hardwired RJ45 Ethernet LAN, and Bluetooth, engineered to eliminate telemetry dropouts and ensure rock-solid cloud connectivity for SAJ residential and commercial inverters.
Triple-Link Redundant Communication (Wi-Fi + LAN + BLE)
Supports wireless Wi-Fi, physical RJ45 Ethernet cable, and local Bluetooth for ultimate connection reliability.
Solves Weak Signal Basement Installs
Hardwired RJ45 port allows reliable Ethernet networking in concrete basements and metal outbuildings where Wi-Fi cannot penetrate.
Instant Bluetooth Mobile Commissioning
Connects directly to installer smartphones for rapid parameter setup without requiring on-site Wi-Fi credentials.
Tool-Free External IP65 Installation
Screws directly into the inverter's dedicated external communication port, maintaining full weather sealing.
More product details
Installing inverters in concrete basements or metal outbuildings often leads to frequent Wi-Fi disconnects and missing solar yield data. The eSolar AIO3 includes a dedicated RJ45 Ethernet port for physical cable runs.
- Fast Ethernet RJ45 port ensures 100% stable data transmission over long cable runs up to 100 meters.
- 2.4 GHz Wi-Fi provides flexible wireless connectivity when running Ethernet cables is impractical.
- Internal local data cache buffers telemetry during internet outages, uploading logs automatically upon reconnection.
Tool-free plug-in installation with rapid mobile app pairing.
The AIO3 screws directly into the bottom of SAJ inverters, drawing power internally from the DC bus and providing instant Bluetooth pairing. Direct Bluetooth Low Energy link allows configuring grid codes and battery profiles in under 3 minutes. Screws into the external aviation/USB port without removing inverter chassis covers. IP65 sealed enclosure certified for harsh outdoor environments (-30 to +60 °C).
Fits both residential and commercial inverter series
A single collector SKU covers single-phase, three-phase, and hybrid installations. Commercial C6 inverters share the same hardware as residential units.
Talks to elekeeper cloud servers and mobile apps
Telemetry updates stream generation curves and battery states in real time. Installers and plant owners monitor performance from any browser or phone.
Pairs Bluetooth for rapid inverter commissioning
Local setup runs over Bluetooth without connecting to the local router first. Network parameters and initial settings configure in minutes.
Technical data
Uninterrupted solar telemetry engineered for difficult concrete basements and high-security commercial networks.
Triple-link Wi-Fi, Ethernet, and Bluetooth data collector for seamless inverter connectivity.
Engineered to eliminate communication dropouts across difficult residential and commercial environments, the eSolar AIO3 combines 2.4 GHz Wi-Fi, a physical RJ45 Ethernet port, and local Bluetooth in a single compact plug-in module. It guarantees uninterrupted telemetry transmission between SAJ inverters and the eSolar cloud platform regardless of Wi-Fi interference or distance.

Why choose the eSolar AIO3 over a standard Wi-Fi-only dongle?
The AIO3 includes a physical RJ45 Ethernet port for rock-solid hardwired networking. While standard dongles rely entirely on 2.4 GHz Wi-Fi (which can drop out through thick basement walls), the AIO3 allows installers to plug in a standard Cat5e/Cat6 Ethernet cable, guaranteeing 100% reliable cloud monitoring.
