WaveShare Solar Power Management Module 6V-24V MPPT

SKU CH-TD8B-HXC0C

Solar power management module with MPPT and multi-protection circuits for 6V to 24V panels, dual 5V outputs, and 14500 battery holder

  • MPPT tracking squeezes more power from 6V-24V panels
  • Five safety circuits guard against over-charge, over-discharge, reverse, heat and current
  • Dual 5V outputs via pin headers and USB port
  • Onboard capacitors cut ripple for steadier voltage
  • 14500 holder plus PH2.0 connector fit 3.7V Li cells

Solar Power Management Module 6V-24V MPPT

This WaveShare module manages power from 6V to 24V solar panels. It includes MPPT functionality to maximise panel efficiency. Two 5V outputs are provided via pin headers and a USB port. The board suits charging 3.7V lithium batteries using the 14500 holder or PH2.0 connector.

Suits off-grid charging and low-power projects

Builders needing MPPT regulation for small panels and single 3.7V cells will find the protection circuits useful. The module is not for systems requiring higher battery voltages or charge currents beyond the onboard limits. Projects without solar input should look at dedicated USB power boards.

Input voltage range 6V to 24V

The DC-002 jack and screw terminals accept panels within this window. An onboard MPPT SET switch lets you select the level closest to the panel voltage to improve charging efficiency. This range decides whether your panel is compatible.

Questions about this item

How do I choose between the DC-002 jack and the screw-terminal input for my panel?

Both accept a 6 V–24 V panel; use the DC-002 jack for a pre-wired plug or the screw terminals for bare wires, then set the MPPT switch to the level closest to your panel voltage.

What does the MPPT function actually do for my charging speed?

MPPT continuously tracks the panel’s maximum power point, so the module extracts the highest possible current from a 6 V–24 V panel and delivers it to the 3.7 V battery via the 5 V outputs.

Which battery connectors can I use with the onboard 14500 holder and PH2.0 port?

The 14500 holder takes a single 14500-size 3.7 V Li cell, while the PH2.0 connector accepts other 3.7 V Li packs; both feed the same charging circuit with over-charge, over-discharge, reverse, over-heat and over-current protection.
