My 2021 Winnebago View 24D experienced a catastrophic Xantrex inverter failure - internal components are charred and the unit is completely inoperative. Rather than replace with another Xantrex unit, I'm considering upgrading to a Victron MultiPlus system.
The RV is equipped with dual 100Ah LiFePO4 batteries and 200W solar array. Current electrical configuration uses the standard Winnebago 12V DC system with 30A shore power connection. The failed Xantrex unit was a 2000W inverter/charger combo with remote panel monitoring.
Which specific Victron MultiPlus model would provide optimal performance for this application? Additionally, what connection modifications will be required, and can the existing Xantrex remote panel be eliminated in favor of app-based monitoring?
For your 2021 Winnebago View 24D, a Victron MultiPlus 12/2000/80 or 12/3000/120 would be excellent replacements for your fried Xantrex inverter. You'll need to rewire the connections and can ditch the old remote panel for Victron's VictronConnect app monitoring.
switching from your fried Xantrex to a Victron inverter in your 2021 Winnebago View 24D is absolutely the right call, and you'll be much happier with the upgrade. Based on your setup with dual 100Ah LiFePO4 batteries and 200W of solar, I'd recommend going with either the Victron MultiPlus 12/3000/120 or the MultiPlus 12/2000/80, depending on your power needs and budget. The 3000VA unit typically runs about $1,200-1,400 (prices vary by retailer and time) and gives you more headroom for running multiple appliances, while the 2000VA unit at around $900-1,100 will handle most typical RV loads just fine.
You're absolutely right about ditching the Xantrex remote panel - the Victron Connect app on your phone will give you far better monitoring and control capabilities than that old remote ever did. The really nice thing about making this switch is that Victron's build quality and reliability is leagues ahead of Xantrex, plus their customer support actually exists and responds when you need help. Your existing 200W solar setup will work perfectly with the new inverter, though you might want to consider adding a Victron SmartSolar MPPT charge controller if you don't already have one - it'll optimize your solar charging and integrate beautifully with the inverter through their VE.Smart networking.
That loud bang and smoke you witnessed tells the whole story about why your Xantrex failed so catastrophically. Xantrex inverters, particularly the ones that come factory-installed in RVs like your View, have notorious reliability issues with their power switching components and thermal management. The faint hissing you heard the night before was likely arcing or corona discharge from components already starting to fail - your instinct to shut it down probably prevented an even worse failure or potential fire.
The root cause of your battery drain issue was probably the inverter itself drawing excessive standby current or having a failing charging circuit that was actually working against your batteries instead of charging them. This is unfortunately common with aging Xantrex units, and the fact that yours failed completely while connected to shore power suggests the AC input circuitry was compromised. Here's what likely happened internally:
Victron inverters use much higher quality components, better thermal design, and more sophisticated protection circuits. Their MultiPlus series has separate AC input and inverter sections that can operate independently, so if one side has issues, it won't necessarily take down the other. They also have much more granular monitoring and protection features that would have caught and prevented the kind of failure you experienced.
Your 200W solar array is actually perfectly sized for your battery bank - it can theoretically generate about 800-1000 watt-hours per day in good conditions. Accounting for charging voltage (typically 14.2-14.6V) and system losses, this translates to roughly 55-70 amp-hours of actual battery charging, which is reasonable for maintaining two 100Ah LiFePO4 batteries during typical RV use. The issue wasn't your solar capacity, it was that failing inverter working against your charging system.
Before diving into the installation, you'll need to carefully assess your current wiring and decide exactly which Victron model fits your needs and space constraints. Start by measuring the physical dimensions where your old Xantrex was mounted - Victron units have different form factors, so you may need to modify the mounting or relocate entirely. The MultiPlus units are generally larger than most Xantrex inverters, so check clearances for ventilation and service access.
For your specific setup with 200Ah of LiFePO4 batteries, here's my recommendation breakdown:
You'll also want to consider adding these components for the optimal setup:
Before ordering anything, document your existing wiring thoroughly with photos and measurements. Note the wire gauges for your DC connections - cable size requirements depend on run length and voltage drop calculations. Consult Victron's installation manual for exact cable gauge requirements based on your specific installation distance and model. Also check what size AC breaker feeds your current inverter - you may need to upsize this depending on which Victron you choose.
WARNING: This installation involves high DC currents that can cause severe burns, fire, or explosion. Use proper safety equipment and ensure all connections are properly fused. Consult a qualified technician if unsure. The installation process is straightforward but requires careful attention to safety and proper connections. Start by completely disconnecting your coach batteries and turning off all AC power sources. Remove the old Xantrex completely, including all wiring connections, and clean up any damaged or charred wiring - don't reuse anything that shows heat damage.
Here's the step-by-step installation process:
The beauty of the Victron system is the initial setup and configuration. Download the VictronConnect app and connect to the inverter via Bluetooth. You'll be able to set up charging parameters specifically for your LiFePO4 batteries, configure AC input limits to prevent tripping campground breakers, and set up custom charging profiles. The app gives you real-time monitoring of battery voltage, current flow, power consumption, and charging status - far superior to any Xantrex remote display.
For your LiFePO4 batteries, configure these charging parameters in the app:
If you're adding a SmartSolar charge controller for your solar panels, the installation is equally straightforward. Mount it in a ventilated location, connect your solar panel wiring to the PV inputs, and run DC output cables to your battery bank with appropriate fusing per manufacturer specifications.ng. The SmartSolar controller will automatically detect your battery type and optimize charging accordingly.
Test everything thoroughly before putting the RV back into service. Check that shore power charges the batteries properly, inverter operation works under load, and all your existing 120V circuits function normally. The Victron app will show you detailed information about power flow, helping you verify everything is working correctly.
While this is definitely a project you can tackle yourself given your experience with RV maintenance and modifications, there are a few scenarios where bringing in professional help makes sense. If you discover extensive wiring damage beyond just the inverter connections, or if your electrical panel needs significant modifications to accommodate the new inverter's requirements, a qualified RV electrician can save you time and ensure code compliance.
The main areas where professional help is worth considering include:
However, given that your local RV shop quoted $400 over retail just for the inverter, I'd recommend finding a different service provider if you do need professional help. Look for marine electricians or RV specialists who work with Victron equipment - they'll be more familiar with proper installation practices and configuration. Many Victron dealers also offer installation services and can provide ongoing support for the system.
If you do hire someone, make sure they understand LiFePO4 battery charging requirements and have experience with Victron's VE.Bus communication protocol. The last thing you want is an installer who sets it up like a traditional lead-acid system, which won't optimize your expensive lithium batteries.
One final consideration is warranty coverage. Installing the Victron yourself won't void the warranty as long as you follow their installation guidelines and use proper wiring practices. Victron offers excellent technical support and comprehensive documentation, so you'll have resources available if you run into any issues during or after installation. Their online community and technical forums are also incredibly helpful for troubleshooting and optimization tips.
Bottom line, Steve - you're making a smart upgrade that will give you years of reliable service and much better insight into your RV's electrical system. The Victron ecosystem is designed for exactly the kind of owner who wants to understand and maintain their own equipment, and you'll appreciate the professional-grade monitoring and control capabilities.
