xVictron BlueSolar MPPT 150/70-MC4 Solar Charge Controller
The Victron BlueSolar MPPT 150/70-MC4 is a solar charge controller designed for professional off-grid and battery-based solar installations. It accepts a maximum PV open-circuit voltage of 150V and delivers up to 70A of charge current, with integrated MC4 connectors for direct panel string connection. Suited to installers working on larger residential, commercial or off-grid systems where a high-current MPPT controller is required.
Key Features
- Maximum PV input voltage of 150V, suitable for series-connected panel strings.
- 70A maximum charge current, supporting substantial battery bank charging from solar.
- Integrated MC4 connectors on the PV input, eliminating the need for separate MC4 adapters at the controller.
- Multi-stage adaptive charging algorithm supports lead-acid (AGM, gel, flooded) and lithium battery chemistries.
- Victron MPPT tracking algorithm responds rapidly to changing irradiance conditions, maximising energy harvest throughout the day.
- Compatible with Victron VE.Direct communications port for monitoring via the Victron Connect app or integration with a GX device.
- Built-in Bluetooth is not included on this model; a VE.Direct Bluetooth Smart dongle can be added separately for wireless monitoring.
Product Overview
The BlueSolar MPPT 150/70-MC4 sits within Victron's BlueSolar range, which does not include built-in Bluetooth (unlike the SmartSolar series). This makes it a cost-effective choice where monitoring is handled through a GX device such as a Cerbo GX, or where a wired VE.Direct connection to a display or data logger is preferred. The 150V maximum PV voltage allows for meaningful string lengths, reducing wiring runs and associated losses on larger arrays.
The 70A output is capable of charging 12V, 24V and 48V battery banks, with the controller automatically detecting the system voltage on first connection. At 48V, the 70A output equates to a maximum charge power of around 3,360W, making this unit appropriate for mid-to-large off-grid systems. The integrated MC4 connectors on the solar input are a practical feature on installations where the PV cabling terminates in MC4 plugs, as is standard with most modern solar panels.
Victron's MPPT algorithm continuously tracks the maximum power point of the connected array. In conditions of partial shading or fluctuating irradiance, this results in measurably better energy yield compared to PWM controllers. The multi-stage charging profile (bulk, absorption, float, and optional equalisation for lead-acid) is configurable via VE.Direct-connected tools, allowing the charge parameters to be matched to the specific battery chemistry and manufacturer recommendations.

- Remote commercial installations where wired monitoring via a GX device is already in place.
- Marine and vehicle applications requiring a high-current MPPT controller with a 150V PV input.
- Agricultural and rural off-grid setups with larger panel arrays connected via MC4 cabling.
- Backup power systems where solar charging is integrated into an existing Victron system.
What Is Included
- 1 x Victron BlueSolar MPPT 150/70-MC4 charge controller
Installation Notes
Installation should be carried out by a qualified electrician or accredited solar installer. The PV input can reach 150V open-circuit, which is a shock and arc-flash hazard and must be handled accordingly. Ensure the battery bank voltage is confirmed before connection, as the controller auto-detects system voltage on first use. For integration into a monitored Victron system, a VE.Direct cable or compatible GX device is required separately. Bluetooth monitoring requires the addition of a VE.Direct Bluetooth Smart dongle, which is not included. For any grid-connected elements of the wider system, G98 or G99 compliance requirements apply and should be confirmed with your DNO.
