# Connecting inverters with NODE® Battery and NODE® Battery High Current

An inverter draws significantly more current than the NODE® Battery can measure. That's why it gets its own shunt: the NODE® Battery High Current. It's installed in addition to the NODE® Battery and handles the large consumers.

## Division of tasks

- **NODE® Battery:** It monitors the auxiliary battery and distributes five protected channels. Its positive side is protected according to the cable cross-section – maximum 200 A.
- **NODE® Battery High Current:** It's a shunt for large consumers and handles currents up to 500 A. Its positive side is also protected according to the cable cross-section – maximum 500 A.

The NODE® Battery is explained in detail in this [video](https://youtu.be/9YVJ2eSaL_I).

## Installation

- **NODE® Battery:** Connect directly to the auxiliary battery.
- **NODE® Battery High Current:** Connect directly to the battery. It belongs on the negative side – pay attention to the correct installation direction.
- **Inverter:** Connect according to the manufacturer's instructions to the NODE® Battery High Current.

**Note:** The adapter connector of the NODE® Battery High Current has an orange locking mechanism on the connector housing. To release the cable, press it down with a small flathead screwdriver and only then pull the cable straight out of the connector. If you pull the cable beforehand, you'll damage the locking mechanism and the cable.

## Configuration in the app

### 1. Open the NODE®

Open the side menu, tap **Configuration** and scroll to the **Your NODE settings** section at the bottom. There you'll find the NODE® Battery High Current (1) and your NODE® Battery (2) – you can tell which is which by the product image. Tap the NODE® Battery High Current.

### 2. Set channel to inverter

Scroll down in the dialog to the **Channels** section. The NODE® Battery High Current has exactly one channel. Open the selection behind **Channel 1** and select **Inverter** there.

### 3. Save

Check that **Inverter** (1) now appears behind **Channel 1**. Then scroll to the end of the dialog and tap **Save** (2) – only then will the setting be transferred to the NODE®.

### 4. Set main battery

Exactly one NODE® provides the battery values for all others. To do this, open your NODE® Battery and turn on **Synchronize all NODE® batteries** – this way you only enter the technology, voltage, and capacity once. Leave the same switch off on the NODE® Battery High Current. Save both NODEs at the end.

**Important:** If the switch is on on both NODEs, both will constantly show 100% charge level – calibration won't change that either.

**Note:** You can change the channel at any time, even with synchronization active – the channel selection is retained on each NODE®.

**From BRAIN® version 2.1.3:** **Inverter** is only available from this version onwards. Older BRAIN® firmware only offers Generator, Consumer, PV system, and Shore power.

## Multiple large consumers

If you want to supply multiple large consumers or rebuild your system, the appropriate distribution is described in the article "Battery system for high currents with Revotion" – it covers the setup with the TEXU distributors 200 A and 400 A.

We also show you the complete setup in this [video](https://www.youtube.com/watch?v=lsiP5n48Eq0).
