Product Information
Bluetooth Module for Compatible Charge Controllers
This module adds Bluetooth to a compatible charge controller, so you can read charge state, history and faults on your phone instead of squinting at a panel display.
Size the array to the limits in the specifications table.
Mount it close to the battery on a vertical surface with airflow around the heatsink, and wire battery first, then panels.

Frequently Asked Questions
How many panels can I connect?
Check the maximum PV input power and voltage in the specifications, and keep the array within both.
MPPT or PWM — which do I need?
MPPT harvests more, especially when panel voltage is well above battery voltage or in cold and low light, and it is the better choice for larger or 24V arrays. PWM costs less and suits small systems where panel and battery voltage are closely matched. This unit is accessory.
Which batteries does it charge?
Check the battery types listed in the specifications and set the matching profile before first charge.
