Tepto Avocado Pro (grid)
The Tepto Avocado Pro is an all-in-one AC-coupled battery storage and inverter designed for balcony power plant installations. This ModbusCloud template covers the grid-side measurement registers: total active power, cumulative energy, and per-phase voltage and current for phases A, B, and C. Using Modbus TCP over the device's built-in LAN or Wi-Fi interface, the ModbusCloud Gateway polls these registers continuously, giving installers and building owners a live view of grid interaction and phase balance across the Avocado, MQ2200, ONE, and Avocado Pro variants.

If a device is not in the library yet, we build the template for free as soon as we have the register data.
Use cases
- Monitor total grid active power in real time to verify the storage system charges and discharges as expected.
- Track cumulative grid energy over time to calculate net import and export figures for billing reconciliation.
- Alert on per-phase voltage deviations on phases A, B, or C to detect grid quality issues early.
- Compare phase currents across A, B, and C to identify persistent imbalance that may indicate a wiring fault.
- Report daily grid power profiles to building owners to confirm self-consumption targets are being met.
Installation
Connect the Avocado Pro to your local network via the RJ45 Ethernet port or Wi-Fi, then note its IP address from your router's DHCP lease table.
In your router, assign a static DHCP reservation to the device's MAC address so the IP does not change between reboots.
In the ModbusCloud portal, add a new device, select the Tepto Avocado Pro (grid) template, enter the device IP address, port 502, and Unit-ID 1.
Trigger a manual poll in the portal and verify that the power and voltages_a registers return plausible values before enabling regular polling.
Things to watch for
Port 502 connects but all register reads return an error.
The device returns a Modbus exception code 1 (illegal function) if the register address falls outside the supported range or if function code 3 is used on an address that expects a different code. Confirm the addresses in the template exactly match the firmware version on your unit, as early Avocado Pro firmware revisions shipped with a slightly different register map.
The gateway connects but power and energy values read as zero.
The Avocado Pro reports grid power as a signed int32 spanning two consecutive 16-bit registers. If your polling tool reads only a single register, the result will be zero or garbage. Ensure the ModbusCloud Gateway uses the int32 type from the template and that byte order is big-endian, which is the standard for this device family.
Phase voltage registers return values that seem ten times too high or too low.
The voltages_a, voltages_b, and voltages_c registers use int16 and report voltage in a scaled integer format. If the displayed value appears off by a factor, check whether your portal is applying an additional scaling factor. Trust the raw register value and confirm against a known AC measurement at the installation site.
The device IP changes after a power cut and the gateway loses connection.
The Avocado Pro obtains its IP via DHCP and has no documented static-IP setting in its web interface. Set a DHCP reservation in your router using the device's MAC address, or place the ModbusCloud Gateway on the same subnet and update the device IP in the portal whenever it changes.
