Description
xVictron SmartSolar MPPT 100/20 Charge Controller (up to 48V)
The Victron SmartSolar MPPT 100/20 is a solar charge controller supporting 12V, 24V and 48V battery systems, with a maximum PV open-circuit voltage of 100V and a maximum charge current of 20A. It is aimed at professional installers and off-grid system builders who need a compact, reliable MPPT controller with built-in Bluetooth monitoring and full VictronConnect compatibility.
Key Features
- Maximum PV open-circuit voltage of 100V, suitable for series-connected panel strings.
- 20A maximum charge current, compatible with 12V, 24V and 48V battery banks.
- Built-in Bluetooth allows direct configuration and monitoring via the VictronConnect app on iOS and Android, with no additional dongle required.
- MPPT algorithm continuously tracks the maximum power point, maximising energy harvest across varying light and temperature conditions.
- Supports lithium (LiFePO4), AGM, gel, flooded and other battery chemistries via configurable charge profiles.
- Load output with programmable street lighting and timer functions.
- Optional VE.Direct communication port for integration with Victron GX devices, CCGX, Cerbo GX and Venus GX systems.
- Compact and lightweight at 0.74 kg, suitable for panel mounting or enclosure installation.
Product Overview
The SmartSolar MPPT 100/20 uses a multi-stage MPPT charging algorithm to extract the maximum available power from a connected PV array and deliver it to the battery at the correct charge voltage. Unlike PWM controllers, MPPT technology converts excess PV voltage into additional charge current, which is particularly beneficial in colder climates where panel voltages are elevated. At a 48V battery system, the 20A output represents up to 960W of charge power from a 100V-maximum input.
The integrated Bluetooth module means the controller can be configured and monitored directly from a smartphone without any additional hardware. VictronConnect provides access to charge settings, historical data, battery voltage trends and fault logs. For larger system installations, the VE.Direct port allows the unit to communicate with a Victron GX device, enabling full system monitoring via the VRM online portal. This makes the 100/20 a practical choice for both standalone off-grid installations and as part of a wider Victron ecosystem.
The load output supports programmable functions including dusk-to-dawn switching, timer-based control and a battery protection threshold, making it suitable for lighting circuits, remote sensors and small DC loads without requiring a separate load controller.

Installation Notes
Installation should be carried out by a qualified electrician or experienced solar installer. Ensure the PV array open-circuit voltage does not exceed 100V under any conditions, including cold temperatures, which raise panel Voc. Verify battery chemistry settings in VictronConnect before commissioning, particularly when connecting lithium batteries. For off-grid systems connected to a Victron GX device, a VE.Direct cable is required separately. This unit is not grid-tied and does not require G98 or G99 notification.
