Neutral-Ground Bonding for Off-Grid and Mobile Systems

In this video, I’ll be providing a comprehensive guide on neutral-ground bonding, explaining how to check if your inverter, inverter/charger, or all-in-one system has this bond and how to create one if needed. This essential safety feature is often overlooked, but it plays a critical role in the proper functioning of your electrical system, especially in off-grid and mobile setups like RVs and boats. We’ll start by looking at what a neutral-ground connection is and why it’s so important. I'll also show you how to manually test for this bond, including the measurements you should expect to see with and without the bond in place. For example, with European inverters, you'll see readings like 230V between live and neutral, and I’ll walk you through similar readings for US systems as well. You’ll also learn how to use a jumper wire to create a neutral-ground bond if your system doesn’t have one. I’ll discuss the implications for off-grid systems, where a permanent neutral-ground bond is crucial, as this will likely be the only place where such a connection can be made. I’ll explain how to test if your system already has this bond, and if not, how to create it safely using your inverter, distribution panel, or other components in your setup. We’ll also explore special considerations for multiple inverters running in parallel, where only one inverter should create the bond to avoid grounding loops and system errors. From there, we’ll move on to mobile systems, which can get a bit more complicated, especially when you're dealing with shore power connections. Mobile setups like those in RVs and boats need to manage two operational modes: Inverter mode (Off-grid mode) Shore power mode (Connected to an external power source) In inverter mode, the neutral-ground bond works just like in a regular off-grid system. However, in shore power mode, things get tricky because shore power introduces an additional neutral-ground bond. I’ll explain why having two bonds is dangerous and how to disconnect the internal bond inside your inverter or inverter/charger to prevent grounding loops and electrical issues. To make things easier, I’ll break down three ways to manage the neutral-ground bond when connected to shore power: Manual bonding, which requires a switch to connect or disconnect the bond manually—though this method isn’t recommended due to potential safety risks. Using a battery charger without introducing any extra grounding into the system—ideal if you don’t need AC pass-through power. Automatic bonding via an inverter/charger or all-in-one system with a built-in grounding relay. I highly recommend this method for RVs and boats because it automates the process, ensuring the bond is managed properly without any manual intervention. I’ll also show a diagram from Victron to illustrate how the grounding relay works. This setup ensures that the bond is created or disconnected depending on whether you’re in inverter mode or shore power mode. For those of you using RVs or boats, an inverter/charger like the Victron MultiPlus 2 with a built-in grounding relay can make your system safer and easier to manage, so you don’t have to worry about accidental grounding loops.
