The Links2 Node 12 is a 12V-class control module for RVs — it switches lights, pumps, and accessories, and reads tank, temperature, fuel, and LPG sensors, so you can automate and monitor your rig's systems from one hub.
The Links2 Node 12 is a DC control and sensor-aggregation module built by LinksWell, Inc. for its Links2 line — it is not a solar inverter, battery charger, or grid-tie device, and none of the UL 1741 / IEEE 1547 utility-interconnection listings apply to it. It runs on a 9-18V DC supply (a standard 12V RV house bank) and handles switching, dimming, and sensor input for onboard RV systems. Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
Critical Power & Interconnection Requirements
- Operating (input) voltage: 9V to 18V DC — sized for a 12V RV battery bank.
- Maximum input current: 80A.
- Output channels: four 30A channels (two configured as H-Bridge sets) plus eight 10A dimmable PWM channels.
- 12 override switches and 12 digital input channels for manual/automated control.
- This is NOT a battery charger, inverter, or Chargeverter — it does not convert AC to DC or DC to AC.
- This unit does NOT connect to grid AC power and has NO grid sell-back capability.
- NOT rated for 24V or 48V DC battery banks — operating window is 9-18V DC only.
- No PV/MPPT solar charging function is present on this device.
The technical friction with multi-channel RV control nodes like this one is voltage drop and heat buildup at the 30A H-Bridge output terminals when installers use undersized wire gauge for long chassis runs. Over months of vibration and thermal cycling, marginal crimps at those high-current channels loosen and cause intermittent output faults or nuisance shutdowns on pump and slide-out circuits. Verify each 30A output run with a Digital Multimeter under load (not just at idle) to confirm voltage drop stays within an acceptable margin at the far end of the circuit, and torque every output terminal to the connector manufacturer's spec with a calibrated torque driver. Because this is a 12V DC accessory circuit and not a branch-circuit inverter output, NEC Article 690/706 does not apply — instead, follow RVIA/NFPA 1192 low-voltage DC wiring practice for conductor sizing and overcurrent protection on each output channel.
Key Benefits
- Four 30A output channels, including two H-Bridge sets, for reversible loads like slide-outs and awnings.
- Eight 10A dimmable PWM channels for smooth interior/exterior lighting control.
- Onboard sensor inputs for temperature, tank level, fuel, LPG, and voltage — no separate monitoring hub required.
- 12 override switches let you operate circuits manually if the control network is down.
- Multiple network interfaces (RS485, CAN/RV-C, USB) for integration into an existing RV control bus.

FAQ
Can this node sell power back to the grid?
No. The Links2 Node 12 is a low-voltage RV control and sensor module, not a grid-tie inverter. It has no grid interconnection function.
What voltage system does this require?
It operates on a 9-18V DC supply, matching a typical 12V RV house battery bank. It is not designed for 24V or 48V DC systems.
Can I parallel or stack multiple Node 12 units together?
[NEEDS VERIFICATION] The manufacturer data provided does not state a parallel/stacking limit for this device. Multiple units can likely be networked via the RS485/CAN ports, but confirm topology limits with LinksWell before wiring more than one node.
Is this UL 1741 listed for utility interconnection?
UL 1741 does not apply to this product. That listing covers grid-interactive inverters. The Links2 Node 12 is a DC control/monitoring node, not an inverter, so no such listing is applicable.
What sensors and accessories does it work with?
It accepts temperature, tank level, fuel, LPG, and voltage sensors directly, and connects to other RV components through RJ45 RS485, 4-pin RS485, RJ45 CAN/RV-C, and USB Type-A ports.
