Solis Cloud Control Integration

This is the Solis Cloud Control API integration for Home Assistant. It allows you to read and control various settings of your Solis inverter. See my blog post for inspiration how to use this integration: Home Assistant Solar Energy Management.

Note

If your primary goal is to monitor data from the Solis Cloud Monitoring API, you might want to explore the Solis Sensor Integration.
Both integrations are complementary and can be used together to enhance your Home Assistant setup.

Installation

After installation restart Home Assistant.

Configuration

or add integration manually:

1. Go to "Configuration" > "Integrations"
2. Click on the "+" button in the bottom right corner
3. Search for "Solis Cloud Control"
4. Click on "Solis Cloud Control" to add the integration

Follow the configuration steps:

1. Enter your Solis API key (KeyID) and token (KeySecret).
2. Select the inverter you want to control from the list. For parallel connected inverters, select master inverter.

After successful configuration, the integration creates a new entity for your inverter. This entity includes the model name, model identifier, firmware version, and serial number.

Supported data loggers

Data logger model	Model Id	Supported
S2-WL-ST	WL	✅
S3-WiFi-ST	WIFI	✅
DLS-W	❓	❌
DLS-L	❓	❌

Note

Please let me know if you have a different data logger model and it works with this integration.

Supported inverters

All Solis inverters should be supported, although the integration has been tested with the following models:

Model name	Model id	Type
S6-EH3P(8-15)K02-NV-YD-L	3331	hybrid
S6-EH3P(29.9-50)K-H	5305	hybrid
S6-EH3P(12-20)K-H	3315	hybrid
S6-EH3P(5-10)K-H	3306	hybrid
S5-EH1P(3-6)K-L	3101, 3102, 3105	hybrid
RHI-3P(3-10)K-HVES-5G	CA	hybrid
RHI-(3-6)K-48ES-5G	F4	hybrid
S6-GR1P(2.5-6)K	0200, 0205	string
S6-GR1P(0.7-3.6)K-M	0101, 0105	string
S5-GR3P(3-20)K	0504, 0507	string

Note

If your inverter is not listed above, please open a GitHub issue using the "New Solis Inverter Support Request" template. Include your inverter's model name, model identifier, and a downloaded diagnostics report.

Features

The integration provides a user-friendly interface to control your inverter settings. It allows you to:

• ⚡ Control storage modes: "Self-Use", "Feed-In Priority" and "Off-Grid" 🟢
• ⏱️ Schedule charge and discharge slots 🟢
• Switch the inverter on or off 🟢 ⚪️
• Toggle "Battery Reserve" 🟢
• Toggle "Allow Grid Charging" 🟢
• Toggle "Allow Export" (in "Self-Use" storage mode) 🟢
• Set maximum output power 🟢
• Set maximum export power 🟢
• Control various Battery State of Charge (SOC) levels 🟢
• Set power limit ⚪️

🟢 - Hybrid inverter
⚪️ - String inverter

It also provides sensors for battery maximum charge and discharge current:

Note

If the inverter doesn't support a specific feature, the integration don't create the corresponding control or sensor entities.

Non-functional features

The integration also meets several non-functional requirements:

• 📦 Batch reading of all inverter settings in a single request to fit within the Solis Cloud API limits.
• 🔄 Retry logic for API requests to mitigate API stability issues.
• ✅ After changing an inverter setting, the integration reads back the updated value from the inverter to verify that the change was applied successfully.
• 🏡 Follows Home Assistant best practices for integration development to ensure a seamless and reliable user experience.

Data updates

By default, the integration updates inverter settings every 5 minutes. This ensures that any changes made outside of Home Assistant—such as adjustments on the inverter itself or through the Solis app—are automatically reflected in Home Assistant.

If you only use Home Assistant to control your inverter, you can turn off this periodic polling. Disabling polling may help if you experience instability or unreliable readings in the official Solis app caused by frequent data requests.

To disable polling for changes:

1. Go to Settings > Devices & services, and select "Solis Cloud Control" integration.
2. On the integration entry, select the ⋮
3. Select "System options" and toggle the button to disable polling.

FAQ

What if the integration reports "B0115" error during initialization?

Most likely, your data logger is not supported by the integration, for example the "DLS-W" model. Replace your data logger with a supported model, such as "S2-WL-ST" or "S3-WiFi-ST", to use the integration.
