We get a lot of questions from our customers about this, so we’ve made a short video with some basic tips on how to wire up the 120-volt AC terminals (AC input 1, AC output 1) on a Victron Energy MultiPlus II inverter/charger including using ferrules and to NOT use the release button when inserting the wires!
Ferrules are inexpensive and help out with most electrical installations. One great place to source them is Ferrules Direct. Here’s a link to the particular ferrules we recommend for the 6 AWG AC out 1 terminals. You would use the 10 AWG gauge version on the AC input terminals. We also have some other recommended tools and terminals you might need in this document.
