DC BATTERYMNG E DUALCIRCPLUS panel

The DC BATTERYMNG E DUALCIRCPLUS panel is an energy management solution designed for marine systems equipped with two battery banks. It includes a Dual Circuit Plus™ battery switch as standard and may feature an automatic charging relay (ACR), providing complete battery management onboard.

The Dual Circuit Plus™ battery switch allows simultaneous switching of two isolated battery banks (typically engine and house) or their combination to power all loads. It isolates the starter and house circuits, protecting the starter battery from discharge and electronic equipment from voltage drops.

This panel is designed for a maximum operating voltage of 32V DC. It provides a continuous current of 350A per circuit, an intermittent current of 525A (for 5 minutes) per circuit, and a starting current of 700A (for 30 seconds) per circuit.

The DC BATTERYMNG E DUALCIRCPLUS panel is specifically designed to manage two separate battery banks, such as one for engine starting and another for house loads.

The Dual Circuit Plus™ battery switch offers three main positions:

OFF: Disconnects both battery banks from the loads.ON: Connects each battery bank to its respective circuit (engine and house) in isolation.COMBINED: Connects both battery banks together to power all loads, useful for emergency starting or combined charging.

The DC BATTERYMNG E DUALCIRCPLUS panel may include an automatic charge relay (ACR). The product description states it can be integrated, providing automated charge management.

An automatic charge relay (ACR) is a device that automatically combines batteries during charging, allowing the alternator to charge both battery banks (engine and house) simultaneously. It automatically isolates them when charging stops, ensuring the starter battery remains fully charged.

The Dual Circuit Plus™ battery switches and automatic charge relays (ACR) integrated in this type of panel are typically rated IP67. This means they are protected against dust and can withstand temporary immersion in water.

The connector terminals on this panel are sized 3/8" - 16 (M10), which corresponds to a metric thread with a 10 mm diameter.

To comply with the switch’s rated currents, a 4/0 AWG (120 mm²) cable is recommended for the main connections.

For installing this panel, you will generally need the following tools:

Wire strippersCrimping pliers for cable lugsDrill or impact driverScrewdrivers

Yes, using the correct fuses is essential for the safety of any marine electrical system. The precise specifications regarding wire sizing and fuse ratings must be checked in the product’s installation instructions and the applicable standards for your setup.

For minimal operation, the panel requires connections to both battery banks (engine battery and house battery) as well as to the onboard loads. Detailed wiring diagrams are provided in the product instructions for correct and safe installation.

The panel integrates the main components such as the Dual Circuit Plus™ switch and potentially the ACR. However, connections to batteries, loads, and external charging sources (such as the alternator) must be completed during installation according to the provided wiring diagram.

This panel is compatible with DC systems with a maximum voltage of 32V DC.

The panel itself manages the current flow and isolation of battery banks, regardless of their chemistry, as long as the maximum voltage of 32V DC is respected. If an automatic charge relay (ACR) is integrated, it is important to check its specific compatibility with the battery types used, although most Blue Sea Systems ACRs are designed for a wide range of batteries.

Yes, this panel is designed to work with alternator charging systems. If the panel includes an automatic charge relay (ACR), it will facilitate efficient charging of both battery banks from a single alternator.

Thanks to its high current capacity (350A continuous per circuit), this panel is suitable for a wide range of boats, from medium-sized vessels to larger ones, requiring robust management of two battery banks and high loads.

Yes, one of the key functions of the Dual Circuit Plus™ switch is to isolate the starter battery from the house loads. This ensures that the starter battery remains charged and available to start the engine, even if the house loads discharge their own battery bank.

Yes, Blue Sea Systems products, and in particular this panel with IP67-rated components, are specifically designed to withstand harsh marine environments, including humidity, water spray, and vibrations.
