Typical Solar Array Sizing
The SmartSolar 100/50 is a versatile choice for both compact solar installations and systems built around larger residential-format modules.
| Battery System | Typical Solar Array |
| 12V Battery Bank | Up to approximately 700W |
| 24V Battery Bank | Up to approximately 1400W |
These figures are provided as general sizing guidance only. The correct solar array depends on battery voltage, individual panel specifications, wiring configuration, installation location and minimum expected temperature. The array's cold-weather open-circuit voltage must remain safely below the controller's 100V maximum. Not sure whether your panels are a suitable match? Contact us for help and we will be happy to review your proposed configuration.
Battery Cable & Fuse Recommendations
Short, properly sized battery cables help reduce voltage drop, heat and charging losses. The SmartSolar 100/50 accepts battery conductors up to 16mm² (6 AWG), which is the maximum cable size that will physically fit its power terminals.
| Installation Component | Recommendation |
| Battery Cable | 16mm² (6 AWG) fine-stranded copper |
| Maximum Terminal Capacity | 16mm² (6 AWG) |
| Recommended Battery Fuse | 70A DC fuse |
The fuse must be selected to protect the battery cable as well as the equipment. The recommended 70A fuse assumes appropriately sized battery wiring and a short cable run installed according to applicable electrical requirements.

VE.Direct Connectivity
The integrated VE.Direct communication port allows the SmartSolar 100/50 to connect with compatible Victron monitoring equipment, including Cerbo GX systems, VE.Direct USB interfaces and other supported accessories.
This makes it easy to include the controller in a larger Victron installation with centralized system monitoring, historical data and remote access through compatible GX equipment.
Additional cables or communication accessories may be required depending on the equipment being connected. Planning a larger Victron system? Contact us for help confirming the components required for your installation.
Battery Charging
The SmartSolar 100/50 uses a multi-stage adaptive charging algorithm and can be configured for a wide range of battery systems. Charging parameters can be adjusted through VictronConnect, or one of the available pre-programmed charging profiles can be selected.
This flexibility makes the controller suitable for properly configured LiFePO₄, flooded lead-acid, AGM and gel battery systems. Always follow the charging recommendations provided by the battery manufacturer.
A compatible Victron Smart Battery Sense or BMV-712 Smart Battery Monitor can transmit battery voltage and temperature data to the controller through Victron's wireless network. This can improve charging accuracy when voltage drop or changing battery temperature is a concern.
Efficient, Fanless Operation
With a maximum conversion efficiency of up to 98%, the SmartSolar 100/50 converts available solar energy into battery charging power with minimal losses. Its fanless design also eliminates fan noise and reduces the number of moving parts in the installation.
The controller can provide its full rated output current at ambient temperatures up to 40°C. At higher temperatures, output may be reduced automatically to protect the controller.
Built-In Electronic Protection
The SmartSolar 100/50 includes extensive internal protection to help safeguard the controller during abnormal operating conditions.
- PV reverse-polarity protection
- PV short-circuit protection
- PV reverse-current protection
- Output short-circuit protection
- Over-temperature protection
- Automatic power reduction at high temperatures
- Internal temperature-compensated charging
- Recovery charging for deeply discharged batteries
Built-in controller protection does not replace properly selected external wiring, fuses, disconnects or overcurrent protection. Solar and battery circuits must remain within the controller's published voltage and current limits.

Frequently Asked Questions
Can I use residential solar panels with the SmartSolar 100/50?
Yes. Many modern residential-format solar panels can be used with the SmartSolar 100/50, provided the complete array remains within the controller's voltage and current limits.
The array's maximum cold-weather open-circuit voltage must remain below 100V, and its total short-circuit current must not exceed 60A. Panel specifications and local minimum temperatures must be considered before choosing a series or parallel configuration.
Can I connect more than 700W on 12V or 1400W on 24V?
Some array oversizing may be possible because the controller limits its charging output to 50A. However, the array must always remain within the 100V maximum open-circuit voltage and 60A maximum short-circuit current limits.
Oversizing should be evaluated using the actual panel specifications, expected operating conditions and minimum installation temperature.
Does the SmartSolar 100/50 work with LiFePO₄ batteries?
Yes. The charging settings can be configured for a compatible 12V or 24V LiFePO₄ battery through the VictronConnect app.
Use the charging voltages recommended by the battery manufacturer and confirm that any low-temperature charging protection required by the battery is provided by its BMS or another suitable control method.
Does Bluetooth require an internet connection?
No. Your phone or tablet connects directly to the controller through Bluetooth for local setup, monitoring and history review.
Internet access may be required to download or update the VictronConnect app, but it is not required for normal local Bluetooth communication.
Can I connect it to a Cerbo GX?
Yes. The SmartSolar 100/50 includes a VE.Direct port and can be connected to a Cerbo GX using an appropriate VE.Direct cable.
This allows the controller to become part of a larger Victron monitoring system and supports remote monitoring when the Cerbo GX is properly connected to the internet and configured with the VRM portal.
What size battery cable should I use?
For a typical full-output installation, we recommend short runs of 16mm² (6 AWG) fine-stranded copper cable. This is also the largest conductor size accepted by the controller's power terminals.
Cable requirements may vary with run length, installation method, conductor temperature rating and applicable electrical requirements.
What size fuse should I use?
A 70A DC fuse is a practical recommendation when the controller is connected with appropriately sized 16mm² (6 AWG) battery cable.
The fuse must be selected to protect the cable and should be installed close to the battery positive connection. Final sizing may depend on the wiring used and the requirements of the installation.
Will it charge a completely discharged battery?
The controller includes a deeply discharged battery recovery function and can begin charging from very low battery voltage when sufficient solar input is available.
It can also reconnect to some lithium batteries whose internal BMS has disconnected the cells. Recovery still depends on the battery design, BMS behaviour and the condition of the battery.
What warranty does the SmartSolar include?
The Victron SmartSolar MPPT 100/50 is backed by a 5-year manufacturer's warranty from Victron Energy, one of the industry's most respected names in off-grid and marine power systems.
If you ever have a warranty question or need assistance with troubleshooting, Sapphire Energy is here to help. We'll work with you throughout the warranty process to get your system back up and running as quickly as possible.
Can I install the controller outdoors?
The electronic components are rated IP43 and the connection area is rated IP22. This is not equivalent to a fully weatherproof outdoor enclosure.
Install the controller in a dry, ventilated location protected from direct rain, water spray, condensation and excessive heat.
Tell us what solar panels and battery you're using, and we'll help confirm compatibility, recommend the correct wiring and fuse protection, and answer any questions before you order. We're happy to review your system and make sure everything works together.
