FIMER TRIO-5.8/7.5/8.5-TL-OUTD (VSN300)
Three-phase PV inverter with AC, DC per MPPT input, energy, temperature and state values over Modbus TCP.
The FIMER TRIO-5.8, 7.5 and 8.5-TL-OUTD are three-phase string inverters for PV systems on homes and small businesses, read over the network through the VSN300 Wifi Logger Card. This Modbus TCP template reads AC power, lifetime energy, voltage and current per phase, DC power per MPPT input, temperatures and the inverter state in ModbusCloud.

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
- Show AC power and lifetime energy of the PV system on a ModbusCloud dashboard next to the energy meter of the grid connection.
- Get an email alert when the operating state of the inverter changes to fault.
- Compare the DC power of both MPPT inputs in the history to find a shaded or failing string.
- Follow the heat sink temperature through the summer to see whether the inverter throttles in the afternoon.
- Export a year of energy readings as CSV for a yield report.
Installation
Fit the VSN300 Wifi Logger Card in the inverter, connect it to the local WiFi network and give it a fixed IP address in the router.
In the VSN300 web interface, open the logger settings and enable Modbus TCP.
Connect the ModbusCloud Gateway to the same network with a network cable.
In ModbusCloud, add a Modbus TCP device with the IP address of the VSN300, port 502 and unit ID 2, then import this template.
Read the scale factors once, set the scale of the matching registers, and check that AC Power and Total Energy show plausible values.
Things to watch for
The Gateway gets no answer from the inverter. What should I check?
Check that Modbus TCP is enabled in the logger settings of the VSN300, that you use port 502, and that the VSN300 and the ModbusCloud Gateway are in the same network. If unit ID 2 does not answer, try 247; which one applies depends on how the card talks to the inverter. Give the VSN300 a fixed IP address so it does not change after a restart.
Why are current, voltage or temperature 10 or 100 times too high?
These values have a separate scale factor register, a power of ten such as -1 or -2. Read the scale factor, then edit the register in ModbusCloud and set its scale to 0.1 for -1 or 0.01 for -2. Check the scale factors again after a firmware update.
Why do some registers read 65535 or -32768?
That is how the inverter marks a value it does not provide. The total DC current and DC voltage can stay empty; use the values per MPPT input instead. On a TRIO with a single MPPT input, input 2 stays empty.
Why does the inverter not answer at night?
The VSN300 is powered by the inverter. When the inverter switches off after sunset, the card is off too and the Gateway gets no answer until the morning. Expect gaps in the history at night and keep this in mind when you set alarms on this inverter.
The AC values work, but the MPPT registers return an error. Why?
On the TRIO the MPPT block starts at address 122, and MPPT Model ID then reads 160. If that register reads something else or returns an error, the block sits elsewhere on this inverter or is missing. Remove the MPPT registers from the device; the AC values and the total DC values keep working.
