MagnaSine Two-Wire Pigtail Adapter for Magnum Auto Generator Start Controller

Seamless External Switching Interface for Magnum Energy ME-AGS Systems

The MagnaSine Two-Wire Pigtail Adapter (ME-PT2) is a genuine Magnum Energy interface accessory engineered to expand the functionality of your Magnum Auto Generator Start (ME-AGS) controller. Designed for off-grid solar, marine, and mobile power applications, this dedicated adapter allows your connected generator to be triggered and controlled by an external switching device.

When building a dependable off-grid or backup power system, reliable communication between your control hardware and generator is critical. The ME-PT2 adapter provides a direct, factory-terminated bridge between the ME-AGS module and auxiliary dry-contact relays, voltage-sensing switches, or manual override circuits. Instead of relying on makeshift wiring modifications that can compromise system integrity, this purpose-built harness ensures secure signal transmission and straightforward installation.

Engineered for Reliable Generator Automation

In complex power setups, users often need to initiate a generator start cycle from a secondary source outside of the standard Magnum network parameters. Whether you are integrating an external battery management system (BMS), a third-party PLC, or a remote manual start switch in a caravan or commercial vehicle, the ME-PT2 two-wire pigtail simplifies the wiring process. One end features a standard modular RJ connector that plugs directly into the compatible port on your Magnum ME-AGS controller, while the other end provides two colour-coded red wire leads ready for termination into your external switching circuit.

Key Features and Benefits

• Direct Plug-and-Play Interface: Features a precision-moulded RJ modular plug for a secure, vibration-resistant connection to the Magnum Auto Generator Start unit.
• External Trigger Capability: Enables third-party relays, BMS dry contacts, or remote toggle switches to command the connected generator to start via the ME-AGS.
• Pre-Terminated Wire Leads: Supplied with dual red pigtail leads for clean, straightforward integration into terminal blocks or external switching relays.
• Genuine Magnum Energy Accessory: Manufactured to exact OEM specifications to prevent communication faults, loose connections, and wiring errors common with custom-crimped cables.
• Clear Identification: Fitted with a factory identification label to ensure accurate part verification during complex system installations and future maintenance.

Reducing Installation Risk in Off-Grid and Mobile Systems

Attempting to splice into proprietary communication ports or fabricating custom RJ harnesses in the field introduces significant risks, including pin-out errors, intermittent signal loss, and potential damage to the control board inside the ME-AGS controller. In mobile environments such as RVs, fifth-wheelers, and marine vessels, vibration can quickly degrade poorly crimped connectors, leading to failed generator starts when backup power is needed most.

By utilising the genuine MagnaSine ME-PT2 adapter, installers and system owners eliminate the guesswork of pin configurations. The factory-assembled strain relief and accurate conductor sizing ensure that the low-voltage start signal is delivered reliably every time your external switch closes the circuit.

Ideal Applications

• Off-Grid Solar Properties: Allowing external lithium BMS relays or auxiliary system controllers to trigger generator backup via the Magnum AGS.
• Caravans, Motorhomes, and RVs: Adding a convenient remote start switch on a secondary dashboard or control panel.
• Marine Vessels: Integrating helm-mounted switches or automated bilge/load management relays into the generator start loop.
• Service and Utility Vehicles: Connecting specialised onboard equipment controllers that require automatic generator power upon activation.
