Why do power and SOC values appear as large unexpected integers?

The scalebloc transmits all values as integers scaled by a resolution factor documented in the Modbus interface specification. If your portal shows raw counts rather than engineering units, check the scaling factor for each register and apply the correct multiplier. The template sets types to int16 and uint16 respectively, matching the register definitions.

The gateway connects but both registers always return zero. What now?

Confirm the scalebloc is not in a booting or alarm state, as the system will not output valid data during startup or fault conditions. Also verify you are connecting to the XF13 port on the master unit, not a slave unit. Slave units do not expose the external Modbus TCP interface independently.

Register 5040 reads negative when the battery should be exporting. Is that correct?

Yes. According to the INTILION Modbus documentation, a negative value on the active power register means the battery is charging, while a positive value means the system is discharging to the grid or loads. Check whether your energy flow convention matches this sign definition before building alerts or dashboards.

Which Ethernet port on the scalebloc should I connect the Gateway to?

Use port XF13 on the master scalebloc only. Port XF14 is reserved for the energy meter connection or chaining to a preceding slave unit. If multiple scalebloc units are stacked, only the master exposes the external Modbus TCP/IP interface on XF13, which represents the combined system state.

Free Modbus template: INTILION scalebloc energy (battery)

The INTILION scalebloc energy is an AC-coupled lithium-ion battery storage system for commercial and industrial sites, deployed in a weatherproof IP55 outdoor cabinet. This ModbusCloud template reads the two core operational registers over Modbus TCP: active power at register 5040 (positive for discharge, negative for charge) and system state of charge at register 5002. With these values polled continuously, operators and energy management systems gain the live visibility needed to track dispatch behaviour and verify that the scalebloc is following its configured operating mode.
