Solar Canopy Solar Mesh Relay

Overview

The RAK4631 Solar Mesh Relay is designed for buyers who need finished outdoor relay hardware rather than assembling a custom enclosure. It combines the RAK4631 platform with four integrated 6V 200 mA solar panels, a top-mount form factor, and a serviceable internal layout for long-term field deployment.

The solar array is built from four 6V 200 mA panels and delivers roughly 3-5W of charging in optimal conditions, and the relay ships with MeshCore installed so setup can focus on placement, power, and configuration. It is well suited for neighborhood coverage extension, trail access points, property boundaries, and other fixed outdoor relay placements.

• RAK4631-based radio platform
• MeshCore installed before shipment
• Fixed dipole antenna for consistent field performance
• Single 6.8 Ah / 6800 mAh 26650 battery design
• Four 6V 200 mA solar panels for roughly 3-5W optimal solar charging charging
• Serviceable enclosure and accessible internals
• Supports OTA updates

Why a fixed dipole antenna?

For a relay that remains in one outdoor location, predictability matters more than compact size. A whip monopole depends more heavily on the surrounding ground plane and installation details, which can introduce additional variability in the field.

The fixed dipole antenna is more self-contained, making performance easier to reproduce from one deployment to the next. That makes it a practical choice for a permanent outdoor relay where consistent coverage matters more than portability.

Why a single 6.8 Ah / 6800 mAh 26650 battery?

This design favors serviceability over pack complexity. A single large-format 26650 cell reduces holders, interconnects, welds, and battery-management overhead while avoiding the balancing considerations that come with multi-cell packs.

That matters because cell imbalance in a multi-cell pack can reduce usable runtime, accelerate uneven aging, and push weaker cells to overvoltage or undervoltage limits before the rest of the pack. A single-cell design avoids that inter-cell balancing problem entirely while keeping battery replacement more straightforward over the life of the product.

Recommended applications

This relay is intended for buyers building neighborhood, trail, property, and off-grid coverage who want the RAK4631 platform in a deployment-ready outdoor enclosure. It is especially relevant for anyone comparing outdoor mesh nodes, solar LoRa relays, or serviceable repeater hardware.

It also fits buyers who recognize the RAK4631 hardware stack from adjacent mesh ecosystems. The unit ships configured for MeshCore, while still offering a familiar hardware platform for comparison and evaluation.

What ships and what to expect

This product is a finished outdoor relay node rather than a bare radio board. Core product highlights include MeshCore installed before shipment, a fixed dipole antenna, a 6.8 Ah / 6800 mAh single-cell 26650 service path, and a serviceable enclosure architecture.

Field performance will still depend on installation height, local RF conditions, solar exposure, and deployment choices, but the design is intended to reduce the effort required to move from purchase to deployment.
