Victron BlueSolar MPPT 150/70-MC4 Charge Controller | SCC010070300

The Victron BlueSolar MPPT 150/70-MC4 is a solar charge controller built for off-grid and battery-based installations that need a high-current MPPT. It takes a maximum PV open-circuit voltage of 150V and delivers up to 70A of charge current, with MC4 connectors built into the PV input for direct panel string connection.

Key features of the BlueSolar MPPT 150/70-MC4

• PV input, maximum voltage of 150V, suited to series-connected panel strings.
• Charge current, up to 70A for larger battery bank charging.
• PV connectors, MC4 integrated on the input, no separate adapters needed.
• Charging profile, multi-stage adaptive algorithm for lead-acid (AGM, gel, flooded) and lithium chemistries.
• Communications, VE.Direct port for the VictronConnect app or a GX device.
• Bluetooth, not built in on this model. A VE.Direct Bluetooth Smart dongle can be added separately.

Product overview

This unit sits in Victron's BlueSolar range, which skips the built-in Bluetooth of the SmartSolar series. That makes it a straightforward choice where monitoring already runs through a GX device such as a Cerbo GX, or where a wired VE.Direct connection to a display or logger is preferred. The 150V maximum PV voltage allows for longer panel strings, cutting down on wiring runs across larger arrays.

The controller auto-detects 12V, 24V and 48V battery banks on first connection. Its MPPT tracking follows the array's maximum power point as irradiance changes through the day, and the charging profile can be set for bulk, absorption, float and equalisation stages depending on battery chemistry.

Applications

Fits off-grid residential systems on 12V, 24V or 48V banks, remote commercial sites already using a GX device, marine and vehicle setups needing a 150V MPPT, and rural installations with larger MC4-terminated arrays.

What's included

• 1 x Victron BlueSolar MPPT 150/70-MC4 charge controller

Installation notes

Fitting should be done by a qualified electrician or accredited solar installer. The PV input can reach 150V open-circuit, a shock and arc-flash hazard that needs handling accordingly. Confirm the battery bank voltage before connecting, since the controller detects system voltage automatically on first use. A VE.Direct cable or GX device is needed separately for monitored Victron systems, and Bluetooth monitoring needs the separate VE.Direct Bluetooth Smart dongle. Unit weight is 3.88 kg.
