Description
The Victron SmartSolar MPPT 100 | 30 is one of the most versatile charge controllers in the SmartSolar family, ideal for mid-sized RV systems, overlanding rigs, van conversions, travel trailers, tiny homes, marine systems, and compact off-grid cabins.
With up to 100V PV input (Voc) and 30A of charging output, it supports 12V and 24V battery systems, including AGM, Gel, Flooded, and LiFePO₄.
Using Ultra-Fast Maximum Power Point Tracking, the controller continuously adjusts to find the true maximum power point—even during shading, cloud transitions, and temperature swings—providing significantly higher harvest than PWM or slower MPPT controllers.
The 100|30 includes integrated Bluetooth for setup and monitoring through the VictronConnect App, providing real-time solar data, history logs, battery status, and system diagnostics.
For wiring diagrams, battery settings, VE.Direct configuration, fuse sizing, and safety notes, refer to the SmartSolar MPPT user manual uploaded to your system.
☀️ SOLAR ARRAY CAPABILITY
This controller accepts PV strings up to 100V Voc, enabling flexible panel arrangements and simplified RV roof layouts.
Output current is limited to 30A, meaning total solar wattage scales with battery voltage.
Maximum Recommended Solar Array Size
| Battery Voltage | Max Charge Amps | Max Recommended Solar (W) |
|---|---|---|
| 12V system | 30A | ≈ 440W |
| 24V system | 30A | ≈ 880W |
Oversizing the array slightly is acceptable—controller will current-limit to 30A safely.
📐 Solar Engineering Table (Vmp / Imp / Series Limits)
| Panel Type | Typical Vmp | Typical Imp | Max Panels in Series (100V max) | Notes |
|---|---|---|---|---|
| 12V 100W panel | 18–19V | 5–6A | Up to 4S | Most common RV panels |
| 12V 200W panel | 18–20V | 9–10A | Up to 4S | May clip current at 12V |
| 24V 200–250W panel | 34–38V | 6–8A | 2S max | Ideal for small 24V systems |
| 24V 350–400W panel | 32–38V | 9–11A | 2S max | Best for high-efficiency arrays |
| 60-cell house panel | 30–33V | 8–9A | 3S (watch cold Voc) | Great for cabins / fixed installs |
Typical RV system examples:
- Two 200W panels (400W total) – ideal on 12V
- Three 150W panels (450W total) – maxing the controller on 12V
- Two 400W residential panels (800W total) – optimal for 24V
