Victron Cyrix vs Argo FET vs Orion is the standard choice for charging a house battery from an engine. All three keep the starter battery safe, but they work very differently. One is a relay, one is an isolator and one is a charger. Here’s how to choose, using Victron’s datasheets. Electrical work can be […]
A Victron MultiPlus well pump setup depends mostly on one detail: whether your pump runs on 120V or 240V. Most deep-well pumps in US homes are 240V, and that changes which Victron units can run them during an outage. Here’s how to work it out using Victron’s datasheets and manuals. Electrical work can be dangerous: […]
A Victron Quattro whole house system is possible, but in a typical US home it means at least two units in split phase, a big 48V battery bank and a plan for which loads stay off. This guide uses the Quattro 120V datasheet to show what a pair of 48/10000 units can carry, and where […]
Running a rooftop unit is the big question with a Victron MultiPlus air conditioner setup. The short answer: a MultiPlus-II 12/3000 can usually run one 13,500 BTU-class RV air conditioner on battery, often with a soft starter. The battery is what limits how long. Here’s the math, using Victron’s MultiPlus-II 120V datasheet. Electrical work can […]
A Victron inverter microwave setup works well as long as you size the inverter by the microwave’s input watts, not its cooking watts. A “1,000W” microwave usually draws far more from the outlet. Here’s how to check, using Victron’s MultiPlus-II and Phoenix datasheets. Electrical work can be dangerous: follow the manual, fuse and size every […]
A Victron mini split setup is one of the best off-grid and RV heating and cooling options. Most modern mini splits use inverter-driven compressors that ramp up slowly, so there’s no big startup surge. The questions are voltage (120V or 240V), continuous watts and battery energy. Here’s how to size it with Victron’s datasheets. Electrical […]
Charging a 300Ah lithium bank takes a long drive: this Orion XS charge time guide works through how many hours the Victron Orion XS 12/12-50A needs to fill one. The math uses the charger’s official 50A rating and the battery specs, and it explains why real drives often take longer. Orion XS Charge Time: The […]
The Victron MPPT 100/30 vs 100/50 choice comes down to one number: how many amps of solar charging you need. Both are SmartSolar controllers with the same 100V input limit, the same case and the same weight. Victron’s datasheet shows where they differ. Victron MPPT 100/30 vs 100/50 Specs Spec SmartSolar 100/30 SmartSolar 100/50 Battery […]
Here’s the Victron lithium Starlink runtime math for the most common van battery: the Victron Lithium Battery 12.8V 200Ah Smart. It stores 2,560Wh at 25°C, according to Victron’s datasheet. How long that lasts depends mostly on which Starlink you have and whether it runs on DC or through an inverter. The Inputs Item Figure Source […]
The Victron Orion XS fuse size and cable gauge both come straight from Victron’s Orion XS 12/12-50A manual. Getting them right matters more than with most chargers, because the XS cuts its charge current when its input voltage sags. Thin cable means less charging, not just more heat. Electrical work can be dangerous: follow the […]
