Reading the specifications

Victron SmartSolar Charge Controller MPPT 150/35 & 150/45 is listed with 13 published specifications from Victron Energy, including system battery voltage of 12V, 24V, 36V, 48V, max VOC of 150V, MPPT trackers of 1 and connectivity of Bluetooth, VE.Direct. Those figures are what decide whether this unit fits your system, so read them against the equipment it will connect to before comparing price.

For a charge controller, the figures that matter most are type: MPPT or PWM, rated charge current in amps, which must exceed the array's short-circuit current with margin, maximum PV open-circuit voltage, the hard limit that must survive cold-morning Voc rise and supported battery voltages (12/24/36/48 V) and chemistries. In any system with a battery and a separate array, the controller is what protects the most expensive component and determines how much of the array's output actually reaches storage.

What to check before ordering

The checks below apply to any charge controller. Run them against the specification table above — most disappointing solar purchases are compatible-on-paper units that fail one of these in practice.

Check the maximum PV input voltage against the array's Voc at your coldest expected temperature, not at 25 °C — Voc rises as temperature falls, and exceeding the limit destroys the controller instantly.
Confirm the controller supports your battery chemistry with the right charge profile. Lithium, AGM, gel and flooded batteries need different absorption and float voltages.
Prefer a unit with temperature compensation or a battery temperature sensor if the bank lives somewhere that gets hot or cold.
Choose MPPT over PWM for anything beyond a very small array. An MPPT controller harvests roughly 20–30% more energy because it converts excess panel voltage into charge current instead of throwing it away.

What people get wrong

Sizing on rated array watts alone and ignoring the voltage ceiling, which is the most common way controllers are killed.
Using a PWM controller with a high-voltage grid-tie panel — the voltage mismatch wastes a large share of the panel's output.
Running the load output beyond its rating instead of wiring heavy loads directly to the battery through a fuse.

Price and availability in United Kingdom

Victron SmartSolar Charge Controller MPPT 150/35 & 150/45 is listed at £ 138 (GBP) for United Kingdom. Solar pricing moves with supply, import duties and exchange rates, and distributors set their own margins, so treat this as a comparison reference and confirm the current figure before you order.

SolarBazaar compares equipment rather than selling it. Shortlist here on specification and price, then buy from an authorised distributor or installer in United Kingdom: warranty cover on solar hardware is normally honoured through the channel you bought from, so confirm who supports Victron Energy locally before ordering.

Victron SmartSolar Charge Controller MPPT 150/35 & 150/45 — frequently asked questions

How much does Victron SmartSolar Charge Controller MPPT 150/35 & 150/45 cost?

Victron SmartSolar Charge Controller MPPT 150/35 & 150/45 is listed at £ 138 (GBP) for United Kingdom. The figure is indicative — solar prices move with supply, duties and exchange rates, and each distributor sets its own margin — so confirm the current price with a supplier before ordering.

What are the specifications of Victron SmartSolar Charge Controller MPPT 150/35 & 150/45?

We hold 13 published specifications for this charge controller, including system battery voltage 12V, 24V, 36V, 48V, max VOC 150V, MPPT trackers 1, connectivity Bluetooth, VE.Direct and connection Screw terminals. The full table is on this page, listed under model VSS-MPPT150/35.

Who makes Victron SmartSolar Charge Controller MPPT 150/35 & 150/45?

Victron SmartSolar Charge Controller MPPT 150/35 & 150/45 is a Victron Energy product, listed under charge controllers with model reference VSS-MPPT150/35. The Victron Energy brand page lists the rest of its range so you can compare across the catalogue.

Is Victron SmartSolar Charge Controller MPPT 150/35 & 150/45 right for my system?

That depends on what it has to connect to. For a charge controller, check type: MPPT or PWM, rated charge current in amps, which must exceed the array's short-circuit current with margin and maximum PV open-circuit voltage, the hard limit that must survive cold-morning Voc rise against the rest of your equipment before price enters the decision. Prefer a unit with temperature compensation or a battery temperature sensor if the bank lives somewhere that gets hot or cold.

Where can I buy Victron SmartSolar Charge Controller MPPT 150/35 & 150/45 in United Kingdom?

SolarBazaar lists and compares equipment rather than selling it. Use the specifications and price here to shortlist, then buy through an authorised distributor or installer in United Kingdom — buying in-channel is what keeps the manufacturer's warranty valid.
