Description
The Victron SmartSolar MPPT 100/30 is a solar charge controller that converts energy from your solar panels into the correct charging profile for your batteries. 100V max panel voltage, 30A max charge current, and built-in Bluetooth for monitoring via the VictronConnect app. Handles up to 440W of solar on 12V systems or 880W on 24V — the sweet spot for RV, marine, and small off-grid installs.
Key Features
- ✓ MPPT tracking — extracts up to 30% more energy from panels vs PWM controllers. Finds the maximum power point in any condition.
- ✓ 100V max PV input — supports high-voltage panel strings. Use fewer, larger panels with series wiring for lower current and thinner cables.
- ✓ 30A charge output — delivers up to 30A to your battery bank. Handles 440W on 12V or 880W on 24V systems.
- ✓ Built-in Bluetooth — real-time monitoring, configuration, and 30-day history via VictronConnect (iOS/Android).
- ✓ LiFePO4 profile — pre-configured for lithium batteries with proper absorption, float, and equalization settings.
- ✓ 12V/24V auto-detect — automatically configures for your system voltage. No manual selection needed.
- ✓ VE.Direct communication — connects to GX devices for remote monitoring and system integration.
- ✓ 5-year Victron warranty — proven reliability in the harshest environments worldwide.

Solar Panel Sizing
| 12V system — 1× 200W panel | ~30A charge, fills 100Ah in ~4 sun-hours |
|---|---|
| 12V system — 2× 200W panels (series) | ~30A charge (controller limited), faster in partial shade |
| 12V system — 2× 200W panels (parallel) | Exceeds 30A — use MPPT 100/50 instead |
| 24V system — 2× 200W panels (series) | ~15A charge at 24V, fills 100Ah in ~7 sun-hours |
| 24V system — 4× 200W panels (2S2P) | ~30A charge at 24V, fills 200Ah in ~7 sun-hours |
Rule of thumb: on 12V systems, this controller handles 1-2 panels (200-440W). For 3+ panels or 600W+, step up to the SmartSolar MPPT 100/50.
Applications
- RV roof solar — 1-2 panels on the roof, charge house battery while parked
- Marine solar — bimini-mounted panels, supplement shore charging while at anchor
- Van life — roof panels + this controller = free daily charging
- Off-grid cabin — primary charging source with battery bank
- Shed/workshop — ground-mounted panel charges tool batteries
Compatible Batteries
- Dakota Lithium 12V 100Ah — 200W panel fills it in 4-5 sun-hours
- Dakota Lithium DL+ 12V 135Ah — 200W panel fills in 5-6 sun-hours
- Dakota Lithium DL+ 12V 320Ah — use 400W+ panels for reasonable charge times
- Dakota Lithium 24V 60Ah — configure for 24V system, 400W array
- Any 12V or 24V LiFePO4 bank — configurable charge profile via Bluetooth
FAQ
What’s MPPT and why does it matter?
Maximum Power Point Tracking continuously adjusts the electrical operating point of your solar panels to extract maximum energy. On cloudy days, partial shade, or non-ideal angles, MPPT harvests 20-30% more energy than simpler PWM controllers. Over a year, that’s weeks of extra free charging.
Can I add more panels later?
Yes, up to the 100V/30A/440W limits. Start with one 200W panel, add a second in series later. If you outgrow 440W, upgrade to the MPPT 100/50 (same features, 50A output, handles 700W on 12V).
Does this work with the MultiPlus?
Yes. Via VE.Direct → GX device → VE.Bus, the system implements Solar & Wind Priority: solar charges first, battery powers loads second, shore/generator supplements only when needed. This minimizes shore power usage and maximizes free solar energy.
Is 30A enough for a 100Ah battery?
Yes — 30A is a 0.3C charge rate for 100Ah, which is optimal for LiFePO4 longevity. Full sun gives you 4-5 hours of 30A charging per day (120-150Ah), which easily fills a 100Ah battery daily. For larger banks (200Ah+), consider the MPPT 100/50.
