Victron - BlueSolar MPPT Charge Controller 150/45 [SCC115045222]

The full large-controller range — same charging as the SmartSolar, without built-in Bluetooth. The Victron BlueSolar MPPT 150/35 through 250/100 covers everything from a 35 A mid-range controller to the 100 A flagships, with 150 V or 250 V of PV input and full 12 / 24 / 36 / 48 V battery support. The charging hardware is identical to the SmartSolar range; Bluetooth simply isn't built in. Add a VE.Direct Bluetooth Smart dongle for wireless setup, or configure over VE.Direct with a GX device. Want Bluetooth out of the box? Choose a SmartSolar model.

Who the BlueSolar MPPT 150/35–250/100 is built for

• Larger off-grid homes and cabins — 48 V banks and multi-kW arrays, where 35–100 A of charge is needed.
• Bluewater and liveaboard yachts — big arch and bimini arrays that have outgrown the 100-series.
• Expedition vehicles and large RVs — rooftop arrays feeding a 24 V or 48 V house bank.
• Installers and GX-monitored systems — the VE.Can models daisy-chain into one synchronised system; if you run a GX device you monitor over VE.Direct anyway.

How to read the model number

• First number = max PV input voltage. 150 V or 250 V — the higher ceiling lets you run more panels in series.
• Second number = max charge current. 35, 45, 60, 70, or 100 A into the battery.

Combine those with the maximum PV wattage your system voltage supports to size the controller. Wesley walks through the full math in our MPPT sizing guide.

VE.Direct or VE.Can?

Every model here has a VE.Direct port. The 150/100, 250/70, and 250/100 add a VE.Can port, which lets you daisy-chain up to 25 controllers into one synchronised system — the right choice for large multi-controller arrays. The smaller VE.Direct-only models are ideal for single-controller systems. (A VE.Can bus needs a 120 Ω terminator at each end — see accessories.)

Tr or MC4 — which PV connection?

The 150/60 and 150/70 are offered in two versions: Tr (35 mm² / AWG 2 screw terminals — you bring your own PV wiring) or MC4 (two pairs of MC4 connectors built in). The other models use screw terminals.

12 / 24 / 48 V is auto-detected; 36 V is selected manually with the software tool. The 150-series runs at up to 98% efficiency, the 250-series up to 99%.

Why this range

• 35–100 A of charge. Covers mid-range arrays right up to multi-kW systems — up to 5,800 W of PV on a 48 V bank with the 100 A models.
• Ultrafast MPPT, up to 98–99% efficiency. The BlueSolar algorithm locks to the true power peak even under partial shading.
• VE.Can on the largest models. Daisy-chain up to 25 units for synchronised charging across a big array.
• Remote on/off + programmable relay on the 60 A and larger models — tie into a VE.Bus BMS and trip the relay on alarms or events.
• Add Bluetooth with a dongle. The VE.Direct Bluetooth Smart dongle gives the same VictronConnect experience as a SmartSolar.
• Multi-stage charging for every chemistry. Eight pre-programmed profiles plus a fully programmable mode; lithium must be set to the correct profile.
• 0 V recovery, passive cooling, 46-day trends. Starts a fully discharged bank, no fan, and stores a month and a half of history on the controller.
