DESCRIPTION
Enerdrive ePRO Plus: Precision Battery Monitoring for 12V to 48V Systems
The Enerdrive ePRO Plus battery monitor is an advanced diagnostic tool designed to provide an accurate, real-time overview of your mobile or off-grid power system. By measuring exact current flow and voltage, this system calculates the true state of charge (SoC) and time remaining for your battery bank, removing the guesswork from your energy management. Whether you are running a remote cabin, a marine vessel, or a touring caravan, it is fully compatible with both traditional lead-acid and modern lithium (LiFePO4) battery chemistries.
Intelligent 500A Active Shunt Integration
At the core of the ePRO Plus is a highly accurate 500A continuous (600A maximum) active shunt. It features a grid-optimised footprint, allowing for seamless physical integration with DC Modular products to keep your wiring clean and safe. High-current connections are made easy using robust M10 stainless steel studs, designed to handle heavy-duty lugs and significant current loads without excessive voltage drop. This intelligent shunt operates within a wide 7V to 70Vdc supply range, ensuring stability across multiple system voltages.
Monitor Up to Three Battery Banks
While keeping a precise eye on your primary house battery system, the monitor offers two additional inputs. These can be configured to monitor the voltage of secondary or tertiary battery banks, such as engine starter batteries. Alternatively, these inputs can be repurposed for mid-point voltage measurement, backlight control, or key switch integration, providing exceptional flexibility for complex 12V, 24V, and 48V DC power setups.
Programmable Alarms and Equipment Control
Beyond standard readout displays like voltage, current, and temperature, this unit includes a programmable alarm relay. This potential-free contact can be configured to automatically start a generator or disconnect external equipment when the battery voltage or capacity drops to a critical level. This actively protects your valuable power storage from deep discharge damage, extending the lifespan of your battery bank.
Key Features
- High-precision tracking: Calculates exact state of charge, voltage, current, and time remaining.
- Broad compatibility: Supports 12V, 24V, and 48V battery systems with a 7V to 70Vdc operating range.
- Active shunt included: 500A continuous rating with a clear fuse cover and M10 connection studs.
- Multi-bank capability: Monitor one primary bank comprehensively, plus the voltage for two auxiliary banks.
- Lithium ready: Perfect for LiFePO4 setups as well as AGM, Gel, and flooded lead-acid batteries.
- Plug-and-play connection: Includes a QuickLink cable between the active shunt and the IP65-rated display unit for rapid installation.
Effortless Installation for Off-Grid Setups
Setting up the Enerdrive ePRO Plus battery monitor is straightforward and requires minimal wiring. The package includes the necessary QuickLink communication cable and fused supply wire, eliminating the need to source a separate connection kit. Simply interrupt the main negative cable to install the shunt into the high-current circuit, run the single data cable to the circular remote display unit, and you are ready to configure the system. The intuitive interface and detailed manuals ensure the installation process is as seamless as possible.
