Victron Energy SmartSolar MPPT 250/100-Tr Solar Charge Controller, 100A, 250V, VE.Can

Overview

The Victron Energy SCC125110412 is a SmartSolar MPPT 250/100-Tr VE.Can solar charge controller for 12 V, 24 V, and 48 V battery banks, with 36 V selection available manually. It delivers up to 100 A charging current and accepts high-voltage solar arrays with a 250 V absolute PV open-circuit limit under cold conditions.

On a boat, this unit fits larger house-bank solar systems where changing light is part of daily use. The MPPT tracking helps the controller keep harvesting when clouds pass, sails or other moving objects shade the panels, and the VE.Can connection lets multiple controllers work together in a larger Victron system.

Key features

• 100 A rated charge current for larger marine solar charging systems.
• Supports 12 V, 24 V, and 48 V battery banks with automatic voltage selection; 36 V systems can be set manually.
• Nominal PV power ratings of 1450 W at 12 V, 2900 W at 24 V, and 5800 W at 48 V.
• 250 V absolute maximum PV open-circuit voltage under cold conditions, with 245 V maximum for start-up and operation.
• Tr terminal version with 35 mm² / AWG 2 PV and battery terminals for hard-wired array and battery connections.
• VE.Can, VE.Direct, and built-in Bluetooth connections for setup, monitoring, and system integration.
• Parallel operation through VE.Can for synchronized charging across multiple controllers on larger installations.
• IP43-rated electronics with an IP22 connection area, suited to protected indoor marine electrical spaces.
• Protection against PV reverse polarity, output short circuit, and over-temperature conditions.
• Safety standards include EN/IEC 62109-1, UL 1741, and CSA C22.2.

Electrical and system integration

This controller fits Victron electrical systems where solar charging needs to be visible and coordinated from the central monitoring setup. VE.Can can daisy chain multiple MPPT controllers to a GX device, while VE.Direct and Bluetooth give local access for commissioning, charging profiles, and live performance checks.

Charge settings can be matched to common battery types such as lithium, AGM, gel, and flooded lead-acid. The unit uses a multi-stage adaptive charge algorithm with default absorption, float, and equalization set points that can be adjusted through the supported setup methods.

Installation and fit

The Tr version is the hard-wired terminal model, with 35 mm² / AWG 2 PV and battery terminals. It measures 216 x 295 x 103 mm and weighs 4.5 kg, so it belongs on a solid vertical panel or bulkhead with service access for cable bends, torque checks, and ventilation.

The enclosure rating makes it a protected-space component rather than a deck-mounted accessory. Install it in a dry electrical locker, machinery space, or electronics area away from direct spray and standing water, with disconnects and over-current protection selected for the vessel installation.

Use cases on board

This controller is a good match for cruising yachts, trawlers, workboats, and fishing vessels carrying larger solar arrays and house battery banks. It is especially useful where panel output changes during the day because of clouds, sail shade, or the boat’s angle to the sun.

Maintenance and care

Keep the connection area dry, secure cables so vibration does not load the terminals, and leave space around the housing for heat to dissipate. Periodic checks of terminal tightness, cable condition, and controller status are worthwhile in saltwater installations, especially after seasonal haul-out or major battery work.

Shipping
We ship worldwide from the United States. Rates are calculated at checkout based on destination and package weight. Some items include free shipping, which will show automatically. Not every product is eligible for international shipping; checkout will confirm eligibility. We do not ship to PO Boxes except through USPS, and not all packages qualify.

Processing and dispatch
Most orders are verified, packed, and handed to the carrier within 1 to 2 business days. Some products may need extra handling time or ship directly from the manufacturer. For certain international orders, inventory transfers between warehouses may add time. If any delay is expected, we will let you know the dispatch date.

Delivery and tracking
Deliveries are handled by trusted carriers such as USPS, UPS, FedEx, and DHL. Estimated arrival times appear at checkout and depend on your location and the service you choose. These are estimates and can be affected by customs or carrier disruptions. A shipping confirmation with a tracking link is emailed when your order ships, and tracking may take up to 24 hours to update. You can also view tracking in your account.

Duties, taxes, and support
International customers are responsible for any customs duties, taxes, and fees charged by the destination country. If these charges are refused and a shipment returns to us, the carrier’s return cost and any re-entry customs fees will be deducted from the refund. If your order is late or you need help, contact cs@qualityboatparts.com and we will assist you.

Quality Boat Parts is a reseller. Many items include a manufacturer’s warranty, and all warranty service is handled directly by the manufacturer. We do not manage or administer warranty claims on behalf of customers.

Warranty terms, coverage, and duration are set by each manufacturer. Issues involving defects, repairs, or replacements must be addressed with the manufacturer’s support team. When available, the warranty period is listed on the product page. If it is not shown, contact us or the manufacturer for details before purchasing.

To start a claim, the customer must contact the manufacturer and follow their process. Keep your proof of purchase and original packaging, and register the product if the manufacturer requires it, as these are often needed for warranty service.

We are happy to help you find the right contact or documentation, but we cannot decide outcomes or intervene in claim resolutions. For guidance, email cs@qualityboatparts.com.
