This Victron MultiPlus-II 2×120 wiring diagram guide explains how Victron’s split-phase inverter-charger fits into a 50A RV. The 2×120 accepts a split-phase 120/240V source (50A shore power) or a single 120V source, with up to 50A per leg. It’s one of the most popular upgrades in big-RV builds, and also one of the most misunderstood, […]
To connect a Victron MPPT to solar panels safely, you need to get two things right: the wiring order and the string voltage. Wire the battery first, then the panels, and make sure your array’s open-circuit voltage never exceeds the controller’s limit: 100V on a 100/30 or 100/50, and 150V on the 150-series (145V operating […]
What size Victron battery charger you need comes down to your battery’s amp-hour capacity, its chemistry and how fast you want it full. Victron’s Blue Smart chargers cover almost everything: the IP65 in 12V 4, 5, 7, 10, 15 and 25A (24V 5, 8 and 13A) and the IP22 in 12V 15, 20 and 30A […]
What size Victron MultiPlus you need depends on two jobs it does at once: inverting battery power to 120V AC, and charging the battery from shore power or a generator. A MultiPlus that’s too small trips under heavy loads; one that’s too big wastes money and idle power. Here’s how to choose using Victron’s own […]
What size Victron shunt you need depends on the highest current that will flow in or out of your battery. Victron sells the SmartShunt in IP21 and IP65 versions in 300A, 500A, 1000A and 2000A. Pick a shunt rated above your biggest continuous current, usually set by your inverter, and you’re done. What Size Victron […]
What size Victron MPPT do you need? Victron names every controller with two numbers, and once you know what they mean, sizing takes five minutes. A 100/30 accepts up to 100V of panel open-circuit voltage and delivers up to 30A of charge current. You need both numbers to fit your array: the voltage rating protects […]
What size Victron inverter you need comes down to three numbers on Victron’s datasheets: continuous watts, peak watts and the temperature the rating applies to. Victron’s names use VA, which confuses a lot of buyers. A “1200VA” or “3000VA” model does not deliver 1,200 or 3,000 watts continuously. This guide shows how to read the […]
A Victron camper van electrical system is the most copied van build on YouTube for a reason: the parts talk to each other, the VictronConnect app shows everything on your phone, and the components are easy to get. This guide walks through a typical build in the order you would plan and install it, from […]
A Victron off-grid system wiring diagram looks scary because of all the communication cables. Will Prowse makes this point at the start of his 1.4-million-view beginner video: pull out the comms cables and the power wiring is simple. This guide walks the diagram in the same order, battery outward, so you can read any Victron […]
A Victron RV electrical system replaces the RV’s stock converter and basic inverter with a set of parts that work together: a MultiPlus-II inverter-charger, a SmartSolar MPPT, a battery monitor and usually a Cerbo GX. This guide explains what each part does in an RV, using the MultiPlus-II 2×120 that full-time RVers like Changing Lanes […]
