Bosswerk Micro inverter (pv)
The Bosswerk Micro inverter is a compact, WiFi-connected micro inverter designed for balcony and plug-in photovoltaic systems, converting DC from one or two solar panels into 230 V AC for direct household grid feed-in. This ModbusCloud template connects via Modbus TCP through the inverter's built-in Solarman logger, reading instantaneous AC output power and cumulative energy yield. With these two registers visible in your portal, you can track real-time generation and verify long-term production totals without relying on a third-party cloud service.

Use cases
- Monitor instantaneous AC output power to confirm the Bosswerk Micro inverter is producing during daylight hours.
- Track cumulative energy yield over weeks and months to verify expected annual production totals.
- Alert on zero power output during expected generation hours to detect panel or inverter faults quickly.
- Compare daily energy readings across multiple balcony installations on one ModbusCloud multi-site overview.
- Verify that power output drops to zero at night to confirm the inverter is shutting down correctly.
Installation
Connect the Bosswerk Micro inverter to your local WiFi network using the inverter's built-in access point and web interface at http://10.10.100.254, then confirm it receives a LAN IP address from your router.
Connect the ModbusCloud Gateway to the same LAN segment as the inverter, ensuring both devices are reachable on the local network via TCP port 8899.
In the ModbusCloud portal, add a new gateway, import the Bosswerk Micro inverter template, and set the target IP to the inverter's LAN address with the default Modbus unit ID of 1.
Verify the connection by checking live readings for the power register: a non-zero value during daylight confirms successful Modbus TCP communication.
Things to watch for
The gateway cannot connect to the inverter. What should I check?
Confirm the inverter has a stable LAN IP from your router and is not operating only in its own AP mode. The Solarman logger listens on TCP port 8899. Ensure no firewall or VLAN separation blocks that port between the ModbusCloud Gateway and the inverter's IP address.
Power reads zero even though panels are in full sunlight. Why?
The Bosswerk Micro inverter goes offline at night and may take a moment to respond after sunrise. If zero persists during strong daylight, confirm the unit ID is set to 1 and that you are polling the correct LAN IP. The inverter's logger can also time out if queried too frequently: a polling interval of 30 seconds or more is recommended.
The energy register value seems much larger than expected. Is it scaled?
On Deye-platform micro inverters, including Bosswerk models, the total energy register is commonly stored in units of 0.1 kWh. Apply a scaling factor of 0.1 in your portal channel configuration to display the value in kWh. Confirm against the inverter's own web interface to validate the scaling for your specific firmware version.
Readings appear intermittently and then disappear. What causes this?
The built-in WiFi logger has limited throughput. Community reports note that querying too many registers at once or at high frequency can cause the inverter to return short or empty Modbus frames. Reduce polling frequency and ensure only the required registers are being read in each request to improve response reliability.
