What is MESHSOLAR?
MeshSolar is an integrated power management and communication solution designed for outdoor low-power devices, consisting of a BMS power management board and an BLE+LoRa communication control mainboard, making it an ideal fit for Meshtastic.
The system features solar MPPT charging, multi-protocol fast charging (supporting USB PD3.0 and 18–25V DC input), intelligent battery management (compatible with 1–4 cells, with overcharge/over-discharge/short-circuit/over-temperature protection and balanced charging), and dual-mode wireless communication : Bluetooth + LoRa.
With its low-power design, extensive hardware expansion interfaces (supporting displays, GPS, and general-purpose I/O), and seamless compatibility with the nRF52840 + SX1262, MeshSolar is perfect for solar-powered systems, remote monitoring, and other applications requiring long-term stable power.

Why Choose mESHSOLAR?
1.Completely Addressing Meshtastic’s Power Consumption Pain Points
The power consumption issue of Meshtastic devices becomes particularly prominent when GPS + LoRa long-distance communication is enabled. Ordinary battery power may last only a few days, whereas MeshSolar’s low-power design + high-efficiency solar charging allows devices to operate continuously for months or even year-round without interruption, making it especially suitable for off-grid environments such as wilderness, farms, and mountainous areas.
2.The Perfect Companion for Outdoor Scenarios—Solar Power
Meshtastic’s core advantage lies in decentralized outdoor communication, but many deployment locations (such as forests, oceans, and remote areas) make frequent charging difficult. MeshSolar directly utilizes solar power, enabling devices to operate long-term even in infrastructure-free environments, fully unlocking Meshtastic’s potential.
3.Professional Battery Management: Farewell to “Extensive” Power Supply
Traditional MPPT solar solutions often feature rudimentary battery management, supporting only single-cell batteries, lacking balanced charging, and overcharge/over-discharge protection, resulting in short battery life and unstable devices.MeshSolar delivers professional BMS (Battery Management System) with multi-mode support for diverse battery types.
Precautions
- Before powering on (for activation, charging, or setup), ensure that the DIP switch settings for the batteries match the solder pad configuration on the back of the main board, and that both correspond to the actual number of connected batteries. Ensure all hardware configurations are correct before connecting to a power source to prevent damaging the circuit board.
- When installing the batteries, carefully observe the correct polarity. Reversed polarity may cause permanent damage to the MeshSolar main board.
- We recommend watching the instructional video beforehand to ensure safe and proper operation.
