The Victron Autotransformer does three jobs: it steps voltage up, steps it down, and balances split-phase loads. The last one is what interests most RV, boat and off-grid owners. With a MultiPlus-II, it can also create 120/240V split-phase from a single 120V inverter, as the MultiPlus-II manual notes. Here’s how it works, using Victron’s own […]
The Victron Filax 2 and the VE Transfer Switch both switch your loads automatically between two AC sources, such as shore power and an inverter or a generator and an inverter. They’re built for different jobs, though. The Filax 2 is ultra-fast and made for sensitive electronics. The VE Transfer Switch handles more current and […]
The Victron EV Charging Station is a wall charger for electric vehicles that ties into a Victron energy system. Its big feature is solar integration: paired with a GX device, it can charge your car from surplus solar instead of the grid. Before you get excited in North America, check the plug and voltage. Here’s […]
Picking the right Victron products for boats comes down to three jobs: keep shore power safe, charge every battery bank, and know what’s happening on board. Victron started in marine power, and its range still shows it. Here are our picks for each job, with the official specs that matter. All facts come from Victron’s […]
The Victron galvanic isolator is a small, sealed box that protects your boat’s underwater metal from electrolytic corrosion. When you plug into shore power, the shore earth wire connects your boat to every other boat on the dock. Low-voltage DC currents can flow along that wire and eat away at your hull, propeller and shaft. […]
The Victron Battery Switch ON/OFF 275A is a manual disconnect for battery systems up to 48V. It’s the big red-and-black knob you turn to isolate a house bank for storage, service or an emergency. Victron’s version has a removable knob, flexible mounting and ignition protection for engine rooms. Here are the official ratings and how […]
A Victron energy meter measures AC power at a point in your system and sends it to a GX device. Most people need one for ESS (Energy Storage System), so the MultiPlus-II knows how much power the house is pulling from the grid and can cut grid import or export. Meters also measure a PV […]
The Victron Argodiode battery isolators let one alternator charge two or three batteries at once without connecting the batteries together. Drain your house battery flat and your starter battery stays full. It’s the old-school way to split charge, with no software and no settings. Here’s what Victron’s datasheet says about the range, and where a […]
A Victron isolation transformer is one of the most important safety parts on a boat that plugs into shore power. Victron’s datasheet says it eliminates any electrical continuity between shore power and the boat. That protects against galvanic corrosion and makes faults on board trip a breaker instead of energizing the water. Here’s how it […]
The Victron Battery Balancer solves a quiet problem in 24V and 48V lead-acid banks. When you wire 12V batteries in series, one battery with slightly higher internal leakage slowly drifts to a lower state of charge. Victron’s manual warns that this imbalance can substantially shorten the bank’s service life. The balancer is a small box […]
