Fronius Mcp
Connects Claude to your Fronius solar inverter via the local Solar API v1, no cloud required. Exposes live power flow data (PV generation, grid exchange, battery state), smart meter readings per phase, battery diagnostics, and device topology. You configure the inverter IP once through conversation, then ask natural language questions about current output, self-sufficiency, or energy totals. Built for local network use with Fronius Symo GEN24 inverters and compatible hardware. Useful if you want conversational access to your solar system without opening the Fronius web interface or mobile app.

fronius-mcp
Real-time solar data from your Fronius inverter, directly in Claude.
Ask things like:
"How much solar power am I generating right now?"
"What's my battery charge level?"
"Am I currently importing or exporting to the grid?"
"How much energy did I produce this year?"
"What can you do with my solar system?"
"Analyse my photovoltaics for me."
Connects to the Fronius Solar API v1 directly on your local network — no cloud account, no subscription, no data leaving your home.
