# Solis

Our EMS supports the hybrid energy storage inverters from Solis (Ginlong).

The S6 energy storage inverters combine PV and battery in a single unit. The inverter talks to the battery over CAN and exposes both on one register map, so our EMS manages the inverter as a hybrid inverter with its battery management system attached.

### Supported devices

* **S6-EH3P30K-H**: 30 kW hybrid energy storage inverter
* **S6-EH3P40K-H**: 40 kW hybrid energy storage inverter
* **S6-EH3P49K-H**: 49 kW hybrid energy storage inverter
* **S6-EH3P50K-H**: 50 kW hybrid energy storage inverter

The inverter is reached over **Modbus TCP** through a Solis datalogger (for example the S2-WL-ST), which acts as the gateway to the inverter's RS485 interface. The **battery capacity is entered during device setup**, it is not read from the inverter, so make sure it is configured correctly.

{% hint style="warning" %}
Configure the inverter for remote control before you add it: set it to self-use mode and allow charging from the grid. Without that, the inverter ignores the setpoints our EMS sends.
{% endhint %}

{% hint style="info" %}
Our EMS uses the volatile remote control registers of the inverter and refreshes them continuously. The stored storage mode and time-of-use schedules are never overwritten, so the settings you configured on the inverter stay intact.
{% endhint %}

{% hint style="info" %}
PV connected to the MPPT inputs of the inverter is not yet available as a separate PV device. The solar production is part of the readings of the hybrid inverter.
{% endhint %}

### EMS functionality

With the current integration, our EMS enables:

* Monitoring of battery status and performance
* Smart charging and discharging control
* Optimization of self-consumption
* Peak shaving and load balancing

Additional functionality may be added over time as integration capabilities evolve.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.voltmasters.io/device-integrations/battery-systems/solis.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
