INTILION scalebloc energy (grid)
The INTILION scalebloc energy is a commercial AC-coupled lithium-ion battery storage system designed for peak shaving, self-consumption optimisation, and load management at commercial and industrial sites. This template reads grid parameters from the energy meter connected to the scalebloc: per-phase voltages (L1-N, L2-N, L3-N), per-phase currents (L1, L2, L3), and per-phase active and apparent power values at the grid connection point. All registers use Modbus TCP via the XF13 Ethernet port of the master unit, with a scaling resolution of 0.1. Connecting the ModbusCloud Gateway to the scalebloc's network gives installers and facility managers continuous visibility into three-phase grid behaviour without accessing the INTILION web interface.

Use cases
- Monitor per-phase voltages continuously to detect sustained voltage imbalance across L1, L2, and L3.
- Track per-phase active power to verify that grid import and export remain within contracted capacity limits.
- Alert on unexpected current spikes on any phase to catch wiring faults or load imbalances early.
- Compare phase currents over time to identify growing asymmetry in three-phase load distribution.
- Report apparent power per phase to building owners as evidence for demand-charge optimisation reviews.
Installation
Enable Modbus TCP on the INTILION scalebloc by confirming the XF13 Ethernet port is active and the unit has a static IP address assigned; verify that the connected energy meter is configured and recognised by the scalebloc's internal EMS.
Connect the ModbusCloud Gateway to the same LAN segment as the scalebloc's XF13 port, ensuring no firewall rules block TCP port 502 between the Gateway and the scalebloc.
In the ModbusCloud portal, add a new device, import the INTILION scalebloc energy (grid) template, and set the unit ID to match the Modbus slave address configured on the scalebloc (default is typically 1; confirm in the communication or Modbus section of the scalebloc interface).
Verify the connection by reading register 6000 (voltages_a) in the portal's live register view and confirming the returned value, divided by 10, matches the L1-N voltage shown on the scalebloc's web visualisation.
Things to watch for
All grid registers return zero. Why?
The 6000-series registers are only populated when a compatible energy meter is connected and recognised by the scalebloc's internal EMS. If the meter is not connected to the XF14 port, not assigned an IP address, or not yet commissioned, the scalebloc will return zero for all grid parameters. Confirm meter connectivity under the scalebloc's web visualisation.
Voltage readings look correct but power values seem wrong. What should I check?
All registers use a resolution of 0.1, meaning raw integer values must be divided by 10 to obtain the engineering value (e.g. a raw value of 2300 = 230.0 V, 250 = 25.0 kW). If your integration is displaying raw integers without scaling, the values will be ten times higher than the actual measurement. Apply the 0.1 scaling factor in your portal channel configuration.
The gateway connects but register reads time out intermittently.
The scalebloc's Modbus TCP server is on the XF13 port, which is also used for general Ethernet traffic. If multiple EMS clients or the INTILION cloud connection are polling simultaneously, TCP connection slots may be exhausted. Reduce poll frequency, ensure only one Modbus master polls the unit at a time, and check that no firewall or switch is dropping idle TCP sessions before the poll interval.
Current registers return negative values unexpectedly. Is this a fault?
Current registers (6006-6008) are signed 16-bit integers and can legitimately return negative values depending on power flow direction and energy meter wiring polarity. Negative current on a phase typically indicates reverse current flow. Verify the energy meter's CT orientation and installation direction match the scalebloc's commissioning documentation before treating the sign as an error.
