Overview

The Victron Energy SCC110020160R is a SmartSolar MPPT 100/20 solar charge controller for 12V, 24V, and 48V battery banks. It manages solar input from boat-mounted panels and charges the battery with a maximum battery current of 20A, making it a practical fit for house battery charging on cruising boats, fishing boats, and compact off-grid marine power systems.

This controller accepts up to 100V PV open circuit voltage and supports nominal PV power up to 290W at 12V, 580W at 24V, and 1160W at 48V. Built-in Bluetooth lets the installer set up, monitor, and update the unit through the VictronConnect app, while the VE.Direct port gives a wired data path into compatible Victron monitoring and GX systems.

For marine installations, the unit should be mounted in a protected electrical space rather than an exposed deck or washdown area. Its IP43 electronics rating and IP22 connection-area rating suit sheltered locations such as a dry locker, cabin electrical panel area, or enclosed equipment compartment with proper ventilation.

Key features

• SmartSolar MPPT 100/20 controller with 20A maximum battery charge current for 12V, 24V, and 48V battery systems.
• 100V maximum PV open circuit voltage gives useful panel-string flexibility while staying within the controller limit.
• Nominal PV power support of 290W at 12V, 580W at 24V, and 1160W at 48V helps match the controller to the vessel battery voltage.
• Built-in Bluetooth works with the VictronConnect app for setup, firmware updates, live data, and performance checks from a phone or tablet.
• VE.Direct port allows wired integration with compatible Victron displays, GX devices, and monitoring hardware.
• Adaptive multi-stage charging and user-defined charge profiles help the controller work with different battery setups when configured correctly.
• Load output with automatic low-voltage disconnect helps protect batteries from excessive discharge on supported installations.
• Protection against PV reverse polarity, output short circuit, and over-temperature conditions adds useful safeguards in a compact onboard power system.
• Operating temperature range of -30°C to +60°C, with full rated output up to 40°C, supports use in hot equipment spaces when ventilation is handled properly.
• Power terminals accept up to 6mm² or AWG10 cable for appropriately sized marine wiring runs.

Installation and setup

Install the controller close to the battery bank when possible, using cable sizes and fusing that suit the charge current and cable length. Keep PV input voltage below the 100V open circuit limit under the coldest expected panel conditions, since solar panel voltage rises in colder weather.

On a boat, mounting location matters. The controller belongs in a dry, serviceable electrical area with airflow around the case, not in the bilge, cockpit, lazarette floor, or any place that may see spray, standing water, fuel vapor, or salt buildup. A neat installation also leaves room to access the terminals and scan Bluetooth data during commissioning.

Electrical and system integration

The built-in Bluetooth connection is useful for checking solar yield, battery voltage, charge stage, and settings without opening a panel. For vessels already using Victron monitoring, the VE.Direct port allows the controller to feed data into a compatible GX-based system for broader energy monitoring.

This unit is a good match for boats adding solar to maintain a house bank, reduce engine charging time at anchor, or keep essential DC loads supported during day trips and longer stays away from shore power. Correct battery profile selection in VictronConnect is important, especially when the system uses lithium, AGM, gel, or flooded lead-acid batteries.

Maintenance and care

Periodic checks should include terminal tightness, cable condition, fuse condition, ventilation clearance, and any signs of corrosion around the installation area. Keeping the controller and wiring dry and clean helps preserve stable charging performance in the saltwater environment.
