# Solar Inverter Modbus MCP

> Solar Inverter Modbus MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-15).

Processes Modbus communication commands and data for solar inverters, enabling remote monitoring and control of photovoltaic systems.

## Facts

- Endpoint: POST https://api.m2mcent.com/solar-inverter-modbus-mcp/api/process
- Price: $0.1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability solar-inverter-modbus-mcp-63de77fd -d '<json body>'
```

Example prompt: Can you read the current power output and grid voltage from my solar inverter using Modbus — the inverter is at unit ID 1 and I want registers 0x0004 and 0x0005?

## When to prefer this

Choose this endpoint when you need to communicate with a solar inverter using the Modbus protocol — especially for reading operational registers (power, voltage, current, energy yield, fault codes) or sending control commands. Prefer this over generic IoT APIs when your device speaks Modbus and is specifically a solar/PV inverter.

## Known failure modes

- Invalid or malformed Modbus command string returns an error response
- Inverter unreachable or offline results in a timeout or connection error
- Unsupported register address returns an exception code
- Malformed input data field causes a 400 bad request
- Payment not fulfilled results in a 402 response blocking execution

## How this service works

The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.

## Output

Returns processed Modbus response data from the solar inverter, which may include register values such as AC/DC voltage, current, power output, frequency, temperature, fault codes, and energy yield figures, depending on the command sent.
