Victron SmartSolar MPPT 250/70-MC4 VE.Can Bluetooth Solar Charge Controller

High-Performance MPPT Solar Charge Controller for 12V, 24V, and 48V Systems

The Victron SmartSolar MPPT 70A charge controller brings advanced Maximum Power Point Tracking (MPPT) technology to your off-grid, mobile, or backup power system. Designed to extract the maximum possible energy from your solar array, this controller uses ultra-fast MPPT tracking to adapt to changing light conditions—delivering up to 30% more energy than traditional PWM controllers and up to 10% more than slower MPPT units, especially under cloudy or partially shaded skies.

With a peak conversion efficiency of 99% and full rated output up to 40°C, this controller operates without a cooling fan, ensuring silent, reliable performance. The built-in Bluetooth Smart interface allows wireless setup, monitoring, and firmware updates via the free VictronConnect app, while the VE.Can port enables wired integration with GX devices and parallel synchronisation of multiple controllers for larger systems.

Ultra-Fast MPPT and Advanced Shading Response

In real-world conditions, clouds and partial shading can cause conventional MPPT controllers to lock onto a local power peak, missing the true maximum power point. The Victron SmartSolar algorithm continuously scans the full power-voltage curve to lock onto the optimal MPP, maximising energy harvest even when shadows fall across part of your array. This is especially valuable for installations on vehicles, boats, or rooftops where shading is unavoidable.

Flexible Charging for Any Battery Chemistry

The controller supports 12V, 24V, and 48V battery banks with automatic voltage detection (36V manual), and includes eight pre-programmed charge algorithms for lead-acid, AGM, gel, and lithium batteries. A fully user-definable charge profile is also available, giving you complete control over absorption, float, and equalisation voltages. Temperature compensation is built in, and optional external voltage and temperature sensing via a Smart Battery Sense or BMV-712 Smart Battery Monitor ensures precise charging even when the controller is mounted away from the battery.

Robust Protection and Reliable Operation

Engineered for demanding environments, the SmartSolar MPPT includes comprehensive electronic protection: PV reverse polarity, PV short circuit, over-temperature, and PV reverse current protection. The electronics are rated IP43, while the connection area is IP22, making it suitable for indoor, unconditioned spaces. With an operating range of -30°C to +60°C and an altitude rating of up to 5000 m, this controller is built to perform in Australia’s harshest climates.

Seamless System Integration

The SmartSolar MPPT is designed to work as part of a complete Victron energy system. Connect it to a Color Control GX or other GX device via VE.Can for centralised monitoring and control, or use Bluetooth to synchronise up to 10 controllers in parallel. For larger arrays, VE.Can allows up to 25 units to operate in synchronised parallel mode, sharing charge current evenly across multiple controllers.

The programmable relay can be configured to trigger on low battery voltage, high temperature, or other events, while the remote on/off input allows a BMS or other external device to disable charging when needed. With 46 days of historical data storage, you can review solar yield, battery voltage, and charge trends directly in the VictronConnect app.

Built for Australian Conditions

From the tropical north to the arid interior, Australian solar installations face extreme heat, dust, and humidity. The SmartSolar MPPT’s convection-cooled design eliminates fan failures, while the fully potted electronics resist moisture and corrosion. The controller derates power gracefully above 40°C, protecting itself and your batteries without sudden shutdowns.

Installation is straightforward with MC4 PV connectors for quick, weatherproof solar array connections and 35 mm² (AWG2) battery terminals that accept heavy-gauge cable for minimal voltage drop. The compact footprint (215 x 250 x 95 mm) and 3 kg weight make it easy to mount in tight spaces such as vehicle compartments or electrical cabinets.

Ready to Maximise Your Solar Harvest?

Whether you’re upgrading an existing off-grid system, building a new caravan setup, or expanding a commercial solar array, the Victron SmartSolar MPPT 70A controller delivers the efficiency, reliability, and control you need. Order yours today and experience the difference that ultra-fast MPPT tracking and intelligent charge management can make to your energy independence.

Versatile Room Divider With Easy Assembly and Strong Coverage
Size: 3 Panel 12FT W
I picked up this Siebwin 3-panel folding room divider mainly for privacy and room separation, and overall it works very well. Assembly is very straightforward, and the divider can be set up, taken apart, and stored without much effort. The fabric quality feels good, and the frame construction is stronger and more stable than expected. The support tubes especially feel well built and help keep the divider standing securely. One feature I really liked is the flexibility of the design. The panels can be used together as a complete divider or separated depending on the setup and available space. That makes it much more versatile for different room layouts or temporary privacy needs. The coverage is also very good, and the size matches the manufacturer’s description accurately. The fabric blocks light and background visibility well enough to provide solid privacy without feeling overly heavy. The wider feet also help improve stability compared to thinner folding dividers. Another positive detail is that everything arrived complete with no missing parts or damaged pieces, which made assembly much easier and faster. Compared to cheaper privacy screens, this one feels more durable and easier to customize depending on the situation. In terms of value for the money, it feels like a very practical and worthwhile purchase considering the size, flexibility, and build quality. Overall, a versatile and well-built room divider with easy assembly, strong privacy coverage, stable construction, complete included parts, flexible panel configuration, and excellent everyday functionality.

Stable, flexible in deployment configuration, creates true privacy and looks great.
Size: 3 Panel 12FT W
This is the second room divider panel I have installed, and there are several features about this one that I like much better than my older one. The fact that there are no gaps and that the material is thicker means you get more privacy or more hiding power, if you wish. My older divider has vertical spaces between each of the panels and the panels are half as wide as the Siebwin panels, so there are many vertical spaces. The Siebwin divider really creates privacy. Another feature that I really appreciate is that the legs are wider and stand off from the floor. On my older one the legs are flat and they're rather awkward to adjust because they create more drag on the floor. The feet on the older one also loosen if you turn them counter clockwise, so adjustments of configuration that require the feet to be moved are more complex. The older divider also must be deployed in a zig-zag fashion because he feet are not as wide, but this new one can be deployed and stable in a straight, an "N" shape or an arc. They are both the same length, but because the older one must be use in a zig-zag deployment it doesn't reach to the length of the new one. The Siebwin divider definitely costs more at $103.48, but it sports several features and advantages over the other brand, so it does a better job and is worth the extra cost.

Easy to assemble, does the job, material is shiny nylon and shows creases, minor defects, sloppy
Size: 3 Panel 12FT W, Size: 3 Panel 12FT W
The Siebwin room divider is a good idea, and for the price, it mostly delivers on the intended functionality. I ordered the 12 foot, 3-panel version mainly to hide an unfinished basement storage area that had become an eyesore. It works well for that purpose and gives the space a cleaner appearance without spending the kind of money that more decorative dividers or custom partitions cost. If you need something temporary, portable, or mainly functional, this is a viable option. There are a few limitations that became obvious during setup and use. The first thing I noticed was that the weld quality on some of the metal poles is fairly sloppy. Once the cover is installed, you do not really see it, but up close, it does not look especially refined or professional. The blackout material also is not a matte canvas style fabric as I expected. It has more of a shiny nylon appearance, and the creases are fairly visible. Being that it’s more of a nylon, I’d be hesitant to try steaming it to remove the creases. However, the creases do not matter if you are using it in a basement, dorm, or shared room, but for photography, video work, or a professional office setting, the appearance could be disappointing. The fabric is thick enough, though. It blocks visibility well enough, but strong light behind it still shows through to some extent, nothing deal-breaking. Also, my fabric appeared to be slightly defective. The hook and loop strip on one of the bottom sections was off-center and couldn't be totally attached because it was lined up with one of the legs. I originally hoped to use this as a video backdrop, but I will probably end up replacing the fabric with a proper green screen or canvas material while continuing to use the frame itself. For now, it does a good job of covering my basement junk. Assembly was actually easier than I expected and took roughly 15 to 20 minutes. The longer vertical poles are tethered together similarly to tent poles, which made setup straightforward and fairly intuitive. The shorter horizontal pieces slide and snap together to the top and bottom of the vertical assembly. After each section is assembled, the divider panels connect together with metal plates and two knurled screws (at the top and bottom), so no tools are really required. A few screws were difficult to start because paint had gotten into the threads, but once they caught, they tightened down normally. The feet install with similar knurled fasteners and help keep the divider reasonably stable. One thing to watch for during setup is the fabric orientation. There is one arrow indicator in the middle of the fabric to indicate up. However, if you need another indicator, the smaller hook and loop strip goes on the bottom while the longer strip goes on top. I realized mine was upside down right before finishing and had to redo it. I wasn't difficult to redo, despite the defect in mine. The overall design is practical and easy to move around. I do like that the panels can fold and bend into different shapes depending on the space. The widened feet help stability, although when trying to stretch the fabric tight, I noticed the poles sometimes wanted to overlap slightly at the joints. Tightening everything helped somewhat, but it still happened occasionally. The divider feels adequate for normal indoor use, though I would not expect premium durability or luxury-level fit and finish at this price point. The entire device can also be easily disabled and stored in a tote if you need it completely out of the way. It comes with assembly instructions, but even if you didn’t have them, it’s easy to build without them (save a mistake or two). In terms of value, I think the Siebwin divider mostly matches its price. Around $100 gets you a large freestanding partition with decent usability and easy assembly, but there are compromises in materials, appearance, and refinement. The defects are also off-putting, but hopefully you won't have them. Higher-end room dividers can easily cost two or three times more, so some of the tradeoffs are expected. I also noticed cheaper alternatives online, but based on the quality here, I suspect those would probably have even more issues. For practical home use, temporary privacy, hiding storage areas, or separating shared spaces, this is a good option as long as expectations stay realistic.

Works well but takes up more space than expected
Size: 2 Panel 8FT W, Size: 2 Panel 8FT W
This room divider does the job for creating a little extra privacy and was easy enough to set up. The panels feel decent quality and the wider feet help keep it more stable than some cheaper screens I’ve tried. My only issue is that it takes up a bit more room than I expected, especially with the feet sticking out. It’s still portable and folds away nicely, but definitely measure your space first. Overall it works well for separating a room or blocking off an area temporarily. i wish it came in other colors
