Description
xVictron BlueSolar MPPT 150/35 Charge Controller
The Victron BlueSolar MPPT 150/35 is a solar charge controller designed for off-grid and battery-based solar systems. It accepts a maximum PV open-circuit voltage of 150V and delivers up to 35A of charge current, making it well suited to medium-sized 12V, 24V or 48V battery systems. It is aimed at professional installers, system integrators and technically capable off-grid users who need a reliable, standalone MPPT controller without Bluetooth built in.
Key Features
- Maximum PV open-circuit voltage of 150V, compatible with higher-voltage series-connected panel strings.
- 35A maximum charge current, suitable for 12V, 24V and 48V battery banks.
- Multi-stage adaptive battery charging algorithm covering bulk, absorption and float phases.
- Wide PV input voltage range allows the controller to continue operating even when battery voltage is low.
- Load output with low-voltage disconnect protects the battery from deep discharge.
- Streetlight function with programmable on/off times based on sunset and sunrise.
- Compatible with Victron VE.Direct communication port for monitoring via a GX device or MPPT Control display accessory.
- Compact and lightweight at 1.4 kg, suitable for panel, wall or enclosure mounting.
Product Overview
The BlueSolar MPPT 150/35 uses maximum power point tracking to extract the most available energy from a connected PV array. Unlike PWM controllers, an MPPT controller can accept a higher PV string voltage than the battery voltage and convert the excess voltage into additional charge current. In practice, this means more energy harvested from the same panels, particularly during low-light conditions and cooler temperatures when panel voltage is at its highest.
The 150V maximum input voltage allows the use of two or three panels in series depending on the panel's open-circuit voltage, which reduces wiring losses compared to parallel configurations. The controller automatically detects battery voltage at 12V, 24V or 48V on start-up, so no manual voltage selection is required. The adaptive charge algorithm adjusts absorption time based on the previous discharge, which reduces unnecessary gassing and extends battery life across lead-acid chemistries including flooded, AGM and gel. Lithium battery profiles are also supported with appropriate configuration.
The VE.Direct port allows connection to Victron GX devices (such as the Cerbo GX) or a dedicated MPPT Control display panel, enabling data logging, remote monitoring and integration into a wider Victron system. The BlueSolar range does not include built-in Bluetooth; installers who require wireless monitoring should consider the SmartSolar equivalent or add a VE.Direct Bluetooth Smart dongle.

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 150V under any temperature conditions, including cold-weather Voc peaks. The controller must be mounted in a well-ventilated location away from direct sunlight and moisture. For grid-connected or hybrid systems, additional equipment and compliance with G98 or G99 requirements will apply. A VE.Direct cable is required separately to connect to GX devices or the MPPT Control display; these are not included in the box.
