Overview
The Victron Energy BlueSolar PWM-Light Charge Controller is a 12/24V PWM solar charge controller for simple off-grid charging on boats, with automatic system voltage detection and rated charge current options from 5A to 30A. It suits protected onboard solar installations where a panel or small solar array is used to maintain or recharge a house, lighting, or auxiliary battery bank.
The controller uses three-stage charging with bulk, absorption, and float stages. It also includes a load output with low battery voltage disconnect, a single-timer lighting control function, and a two-digit seven-segment display for setting load behavior without adding a separate remote display.
For marine use, the IP20 enclosure should be mounted in a dry, protected location such as an electrical locker, cabin panel area, or sheltered console, not where it will see spray or washdown water. The unit supports a maximum solar voltage of 28V on 12V systems and 55V on 24V systems.
Key features
- 12/24V battery system support with automatic voltage detection after battery connection.
- PWM solar charging with bulk, absorption, and float stages for straightforward battery maintenance.
- Load output includes low voltage disconnect to help protect the battery from excessive discharge.
- Lighting control with one timer, plus day and night timing modes for simple onboard light circuits.
- Two-digit seven-segment display for setting and checking load output functions at the controller.
- Protection for battery reverse polarity by fuse, output short circuit, over temperature, and overload conditions.
- IP20 enclosure with 5 mm² or AWG10 terminals for protected indoor mounting.
- Operating temperature range of -20°C to +50°C at full load.
Variants
This BlueSolar PWM-Light controller range is offered in four amperage configurations for different solar array and load sizes.
The amperage rating changes by variant, while the 12/24V automatic voltage detection, PWM charging method, low voltage load disconnect, IP20 enclosure rating, terminal size, and 70 x 133 x 33.5 mm housing dimensions remain consistent across the range.
- SCC010010000, Amperage 10A. This version fits small onboard solar charging setups where the connected solar current stays within a 10A controller rating.
- SCC010030020, Amperage 30A. This version covers the highest current rating in the 12/24V PWM-Light range for larger protected solar installations.
- SCC010020020, Amperage 20A. This mid-range version gives more current capacity than the 10A model while keeping the same controller format and basic setup method.
- SCC010005000, Amperage 5A. This lower-current version suits compact solar maintenance or lighting-control circuits on small 12V or 24V systems.
Installation and setup
Connect the battery before connecting the solar array so the controller can recognize whether it is working on a 12V or 24V system. The display shows 12 or 24 when the battery voltage has been detected, which is a useful check during installation.
Use a 36-cell solar panel arrangement for a 12V battery system. For a 24V battery system, use a 72-cell solar array or two 36-cell panels in series. Solar and load ratings should not be exceeded, and the controller should be mounted vertically indoors with natural convection space around it.
Electrical and load behavior
Absorption charge voltage is 14.2V on 12V systems and 28.4V on 24V systems. Float voltage is 13.8V on 12V systems and 27.6V on 24V systems, with very low self-consumption of less than 10 mA.
The load output disconnects at 11.2V or 22.4V to reduce the chance of deep discharge. It can reconnect manually at 12.6V or 25.2V, or automatically at 13.1V or 26.2V after the battery has recovered.
Marine fit and mounting
This controller is a practical fit for boats that need simple solar charging without network integration or app-based configuration. Typical locations include a dry cabin electrical panel, a protected locker near the battery bank, or a helm console that is shielded from spray.
Because the enclosure is IP20, it should not be installed in an engine space with heavy moisture, an exposed cockpit, or anywhere saltwater can reach the terminals. In a marine installation, keeping the controller dry, strain-relieving the wiring, and protecting circuits with the correct fusing are as important as selecting the right amperage rating.
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.
