If you want to upgrade a small RV or trailer solar setup without rewiring everything, this MPPT controller adds smarter charging with built-in Bluetooth. Its 100V PV limit and 20A output fit matched arrays, so you can monitor charging in real time.
When a small RV or trailer array needs to pull more usable power from the same panels, controller efficiency starts to matter. This unit uses ultra-fast Maximum Power Point Tracking with Advanced Maximum Power Point Detection to stay on the strongest operating point in changing light and partial shade. With up to 98 percent efficiency and up to 30 percent higher yield compared to PWM charge controllers, it pulls more charging current from a modest array and you see steadier battery charging through the day.
A controller swap gets complicated fast when battery chemistry changes or charging behavior is hard to verify after install. Built-in Bluetooth Smart connectivity works with the VictronConnect app for wireless setup, monitoring, updates, and charging synchronization, and the controller supports lithium, AGM, gel, and flooded batteries with automatic voltage selection and dedicated charging profiles. Instead of guessing what the charger is doing, you can check settings, confirm battery type, and watch real-time performance without pulling the unit back out.
Small systems get into trouble when loads keep draining the battery after the sun drops or when charging never quite reaches full. This controller uses an intelligent load output with built in protection to disconnect loads at a preset voltage, and the BatteryLife algorithm adjusts load disconnect levels to ensure regular full recharging and extend battery life. In day-to-day use, that means lights, fans, or other small DC loads stop pulling the battery too far down and the bank spends more time returning to a healthy charge state.
Many upgrades fail because panel voltage, not panel wattage, ends up being the real limit. This controller accepts 12V, 24V, and 48V battery systems, with nominal PV power rated at 12V at 290 watts, 24V at 580 watts, and 48V at 1,160 watts, plus a maximum PV open circuit voltage of 100V. That gives a small-to-mid system more room than entry-level controllers, but still keeps array sizing honest so a correctly matched setup charges cleanly without running into avoidable overvoltage problems.
Controllers often end up buried in a cabinet or utility bay, which makes troubleshooting harder than it should be. This unit keeps the hardware compact and robust while adding a VE.Direct communication port for wired connection to GX devices, computers, and the VRM remote management platform, with remote monitoring and management available through the VRM portal when paired with a communication center. Once installed, you can keep tabs on charging performance, alerts, and system behavior without having to reach the controller every time something changes.

Hi, everybody. Andy here with etrailer. Let's take a quick look at this Victron SmartSolar MPPT Solar Charge Controller. Now the job of this controller is to take power from your solar panels and efficiently charge your battery bank. And what makes this one nice is it does use that MPPT technology, which means that it's constantly optimizing the solar input so you can get the most energy possible. This is gonna be especially helpful when sunlight changes due to clouds or shade.
And compared to more inexpensive controllers, you're gonna noticeably get better performance and faster charging with this unit. This is rated for 20 amps of charging current and it can handle up to 100 volts from your solar array, which is gonna give you the flexibility in how you wire your panels. It's gonna automatically work with 12, 24 or 48 volt battery system so you don't have to buy different controllers. If your system voltage changes later. In real world terms, that means that this is gonna be able to handle 290 watts on a 12 volt system, 580 watts on a 24 volt system and 1,160 watts on a 48 volt system.
Another big plus is this does have built-in Bluetooth, so you're gonna be able to monitor and configure right from your phone using Victron's app. No extra display or cables are gonna be needed. You're gonna be able to see the charging status, the battery voltage, historical data, and tweak those settings very easily in that app. And again, that app is gonna be a free download. This is gonna support multiple battery types, including lead acid and lithium, and has built in protection for overheating, short circuits, and reverse polarity.
So this is gonna be reliable. It's gonna be safe. Lemme see if I can give you some measurements here just so you have a good idea of its size. So looking at what I'm calling the width here, we're sitting pretty close to 5 1/4 inches wide. Overall height, about 3 and 15, 16 inches tall, almost 4 inches tall depending on the angle there.
And then the depth right at about 2 3/8 inches deep. So overall, this controller is going to be a great fit for off-grid setups for RVs, for boats, or small solar systems where efficiency, reliability, and ease of monitoring all are going to matter for you. If you have any other questions, whether it's about this or anything that we have here at etrailer, don't hesitate to reach out. 'cause ultimately we do wanna make sure that you're getting exactly what you need. Well again, my name is Andy. Thank you for joining me.
