SAJ eSolar Wireless-pro Meter (dual-channel LoRa smart meter)

SAJ's wiring-free grid meter for the EK90 HS5 generation: a dual-channel smart meter that talks to the inverter over LoRa — no data cabling between the meter board and the inverter — enabling import/export sensing, export limiting and the AI energy-management features.

  • Wiring-free LoRa link to the EK90 inverter — optimal range 150 m, including through walls
  • Dual-channel sensing for grid import/export and load monitoring
  • One-Click Self-diagnosis with meter & CT phase auto-adjustment via the elekeeper App
Wireless connection to EK90; up to 150 m under the stated wall-penetration condition

Configuration 2

No — that is the point of this meter. It communicates with the EK90 inverter over LoRa with an optimal range of 150 m even through walls, so retrofitting a data run between a distant meter cabinet and the inverter location is unnecessary. If the site is beyond reliable radio reach (long distances, heavy shielding), the EK90 also supports wired meter connections over RS485 as the fallback — confirm the wired meter model with SAJ when quoting.

Real-time grid import/export sensing at the connection point. That is the input for self-consumption optimisation, load monitoring, the AI Saving energy management and — critically for German installs — export limitation / zero-export control, where the meter interacts with the inverter to keep feed-in within the permitted limit. Without a grid-point meter these functions cannot work.

Availability & compliance 2

SAJ's manual describes the EK90 system as 'providing' a dual-channel wireless meter, i.e. it is the system's default metering device. Scope of delivery can differ per market and configuration, so confirm whether your EK90 package includes the Wireless-pro meter or whether it must be added — we check this against the current SAJ order lists when you request a quote.

SAJ documents it as a control and monitoring meter for the storage system — measuring parameters and interacting with the inverter for energy management and zero-export control. SAJ does not state an MID billing approval for it in the published EK90 material, so do not use it as a substitute for the utility's billing meter; it sits alongside the DSO's meter. If a project needs certified sub-metering, ask us to confirm the applicable SAJ meter option.

Operation & warranty 1

Through the elekeeper App as part of the EK90's 3-step initialization: the One-Click Self-diagnosis function automatically verifies the installation and adjusts meter and CT phase assignment, which removes the classic swapped-CT commissioning error. Minor deviations can be calibrated remotely per SAJ's installation story.
