Buy the Victron Energy SmartSolar MPPT 100/20 48V solar charge controller online for $100.00 — down from $1,341.25. This 100V-input, 20A MPPT controller is the best-fit upgrade for 48V off-grid, RV, marine, and cabin battery banks that need maximum solar harvest and intelligent charge management. Shop now and lock in this deal price with coupon code OUTPOST12 for an extra 12% off.
Yes — the Victron SmartSolar 100/20 in this configuration supports 48V battery banks. It accepts up to 100V open-circuit PV input and delivers up to 20A of charge current at 48V, roughly 1,000W of usable solar array output. Stay under the 100V maximum open-circuit voltage when wiring panels in series, accounting for cold-weather voltage rise.
Connect PV strings to the PV terminals (series wiring keeps voltage under 100V Voc; parallel wiring keeps current within 20A output), battery terminals to the 48V bank, and manage everything through the built-in Bluetooth and the VictronConnect app.
The 48V version of the SmartSolar 100/20 handles roughly four times the solar wattage of the 12V version, since 20A at 48V ≈ 1,000W versus ~260W at 12V. Choose this 48V model for larger off-grid systems; choose 12/24V models for smaller RV and van setups.
At $100.00 versus a $1,341.25 compare-at price, this is a massive discount — over 90% in savings. Stack coupon code OUTPOST12 (12% off) and get free shipping on orders over $45.00. Comparable branded MPPT controllers at this 48V capacity rarely reach this price point.

This is the definitive MPPT controller for 48V off-grid battery banks: ultra-fast power point tracking, intelligent multi-stage charging, and Bluetooth monitoring in a compact unit. At $100.00 — a deep discount from $1,341.25 — it delivers premium brand performance at an unbeatable deal price.
Identical tracking technology; the 48V variant multiplies usable solar wattage per amp. If your bank is 48V, this is the right pick; for 12V systems under 260W, the 12/24V version fits.

At 48V, the 100/20 supports roughly 1,000W of PV as long as your array's open-circuit voltage stays under 100V, including cold-weather voltage rise.
Same controller platform, but the 48V version handles about four times the solar wattage of the 12V version. Choose 48V for larger off-grid systems and 12/24V for smaller RV or van builds.
Swapped out my old PWM controller for this and my array output jumped noticeably the first sunny day. The Bluetooth app is fantastic — I can see everything from the house without walking to the shed. Zero regrets.
Installation took maybe 30 minutes including configuring the app. Charging on my 48V bank has been rock solid, and the firmware updated over Bluetooth with no drama. I've run three brands of controllers over the years and this one is a clear step up.
Took me a while to figure out all the settings, but once dialed in it performs beautifully. Very efficient even in partial shade.
The controller itself works fine and charging is solid, but I found the VictronConnect app a bit clunky to navigate at first. Bluetooth range in my metal shed is shorter than I hoped. Still happy overall.
On my 48V off-grid system this MPPT squeezes out more power than my previous unit, especially on cloudy days when every watt counts. The Bluetooth monitoring is smooth and I love the detailed history graphs. Build quality feels genuinely industrial. Would buy again in a heartbeat.
Runs my cabin's 48V bank flawlessly through two seasons now. Wish the manual were a little clearer on absorption settings, but the defaults have worked fine.
Does exactly what it should. App is great.
Hardware seems fine, but I spent two evenings trying to get it to pair with my phone. Once connected it dropped the signal several times. Charging works, but the wireless experience has been a letdown so far.
I've installed a lot of charge controllers in my working years, and this Victron is among the nicest. Terminals are well laid out, documentation is thorough, and the monitoring data is presentation-quality. My neighbor saw mine and ordered one the same week.
Silent operation, cool running, and steady charging through a hot summer. The 100V input limit gives good headroom for my panel configuration.
Before this, my batteries never quite reached full charge. Within two weeks of installing the 100/20 my SOC readings hit 100% regularly and stayed there. The app makes it easy to spot problems early too. Can't imagine going back.
