Our Project

Solar Cloud Control is an ESP32-based device that connects to your solar inverter via Modbus and provides both local and remote monitoring and control capabilities.

Using our system, you can monitor your solar production, battery status, and energy consumption in real-time, as well as control your inverter settings from anywhere in the world through our cloud service.

What sets Solar Cloud Control apart is its powerful automation engine that allows you to create custom rules based on time, weather conditions, and system parameters, optimizing your solar system's performance without manual intervention.

Solar panels with monitoring equipment

Key Capabilities

Comprehensive Monitoring

Monitor over 50 parameters from your inverter including PV voltage, battery status, load consumption, grid input/output, and system temperatures.

Complete Control

Change inverter operation modes, charge priorities, output sources, and parameters remotely. Set your inverter to prioritize solar, battery, or grid power.

Flexible Automation

Create conditional rules with our simple syntax: when specific conditions are met, defined actions are executed.

Cloud & Local Access

Access your system through our cloud platform from anywhere or connect directly to your device on your local network.

How It Works

1

Connect Your Inverter

Connect an ESP32 device to your solar inverter using Modbus communication. Our firmware can be easily flashed onto any standard ESP32 device.

2

Configure Your Device

Use the captive portal to connect your device to WiFi and obtain your unique cloud access link. Set your location for accurate weather forecasts.

3

Access Your System

Use your custom cloud link to access your inverter from anywhere. View the intuitive energy flow diagram and control your system.

4

Create Automations

Set up automation rules to optimize your system based on your needs. Create rules that respond to changing conditions like power outages or weather forecasts.
