Software release 5.8

The release in brief: 

Improvements of Modbus API 

In version 5.8 we have made it possible to set import/export thresholds via Modbus, which can be relevant, for example, when you want to prevent export when electricity prices are negative through external integrations. You can read about other changes below.

Modbus API

• Grid limit control added to API, enabling setting of import/export thresholds in the same manner as through the portal.
• Battery control reworked to have more intuitive usage with several batteries
• Battery control reworked to use same back-end configuration as portal
