IonVolt Bridge

No cloud? No problem.

A Raspberry Pi at home talks to your Duracell or SolaX battery directly, and your phone talks to the Pi. Readings, changes and your automations keep working when the internet doesn't.

Why run IonVolt at home

Local

Straight to the house battery.

The Pi holds the inverter's own connection on your Wi-Fi. No maker's cloud in the middle, so changes land in seconds and every setting is available.

Resilient

Works without the internet.

Live readings, history and your automations run on the Pi. At home, your phone reads it directly over your own network.

Anywhere

And from anywhere.

When you're out, the Pi keeps IonVolt's server up to date, so the app works away from home too.

Ready in three steps. Nothing to type.

1

Write the card.

Download the IonVolt Bridge card from the IonVolt app and write it to a microSD card with Raspberry Pi Imager.

2

Start the Pi.

Card in, network cable or Wi-Fi, power on. In about three minutes it finds your inverter by itself.

3

Pair it.

In IonVolt: Connect your house battery › On your own network › Ready-made card › Find My Bridge, then Pair This Bridge.

Get IonVolt Bridge in the app

IonVolt Bridge is for IonVolt customers, so it comes from the IonVolt app rather than this page. Sign in, then go to Connect your house battery › On your own network (or Settings › Integrations › House battery › Local Hub).

  • Ready-made card: tap Download the Pi Card. The download link lasts 15 minutes; the app makes a new one whenever you need it.
  • Your own Pi: choose Command line and tap Install on Your Own Pi for a one-line command to paste into the Pi's terminal. It also lasts 15 minutes.
  • Updates: the ready-made card updates itself overnight, proving it's paired with your account. On your own Pi, the app shows the update command, or add --auto-update once.

Exploring the app's demo? Downloading the Bridge needs a free IonVolt account. Each download is linked to the account that asked for it, and the Bridge is licensed for personal use with IonVolt (see the terms).

What you need

  • A Raspberry Pi Zero 2 W, 3, 4 or 5, with its power supply.
  • A microSD card of 8 GB or more.
  • A Duracell inverter with its Wi-Fi dongle on the same network as the Pi, or a SolaX X1 or X3 Hybrid G4 or G4 Fit with a Pocket WiFi 3.0 dongle, or an RS485 adapter wired to the inverter (SolaX guide). Works with SolaX.

Good to know

  • It updates itself overnight.
  • Check on it from a computer on the same network at ionvolt-bridge.local. It shows no keys and can't change anything.
  • Already run a Pi? Install it yourself with one command: see the full guide.
