Main Battery Function

Updated 24 August 2026 · View as Markdown · Automatically translated from German · View original

The main battery or primary battery function is a feature that sets one of Revotion's battery modules as the 'main battery'. This means that this module is used as the primary value and the values from other batteries are added to it. The advantage of this is that all currents can now be calculated together, allowing you to achieve more accurate results.

It doesn't matter how many battery modules you use; the only important thing is that these modules are installed in parallel from the battery onwards.

It also doesn't matter which battery is set as the main battery. Any of them can perform this function for a battery bank. The main battery is then the module that must be completely configured and calibrated, and it's the one from which the app retrieves the data to calculate the SoC (State of Charge).

The other modules then only act as current meters and send this data to the main battery. The channels still need to be configured individually for each NODE to display them correctly in the Energy Widget.

This way, the individual voltage and total consumption are still displayed on every screen of the individual batteries. Remaining time, charging time, and state of charge (SoC) are determined from all of them together and therefore apply equally to all.
