NM-Solar Solar Energy Storage UPS Board

NM-Solar is a solar energy-storage UPS board for low-power IoT, supporting USB-C, DC, and 6V/18V solar input with selectable MPPT and modular outputs.

USB-C, DC, and 6V / 18V solar inputs
30 uA board standby and 1S lithium-ion battery charging
Three output slots for PACK, 5V/3.3V, and 12V modules

NM-Solar-4.2V/3A is a solar energy-storage UPS board for low-power IoT devices. It supports one to four parallel 3.7V 18650 cells, selectable 6V or 18V solar MPPT, and up to 30W combined output.

Dependable power for off-grid nodes

It is suited to LoRa, Zigbee, Meshtastic, and MeshCore nodes, agricultural monitoring, GNSS fixed stations, remote sensors, and short-term UPS backup for home gateways. Confirm input selection, output modules, and the 30W total limit in the Wiki before deployment.
