Dyness MPPT Solar Charge Controller with Bluetooth APP Control 40A 12V/24V

- 40A MPPT, 12V/24V
- Built-in Bluetooth module
- Lithium, AGM, gel, flooded
Our take
Best for a mid-size RV with 40A of solar and a need for phone control.
Why it made the shortlist
Dyness's 40A MPPT has a Bluetooth module built in and connects to a mobile app for monitoring and control. Dyness's 40A MPPT controller connects to its mobile app through an integrated Bluetooth module and supports 12V/24V banks. The listing names lithium, AGM or sealed, gel, flooded and user-defined battery settings, plus overcharge and over-discharge protection.
It has more tracking capability than the PWM-based ECO-WORTHY 30A Bluetooth and VIXKPIRR 30A, and unlike Renogy Rover 2 20A it needs no extra module.
It asks for a bigger budget than the PWM units here, so choose it when you want tracking and an app in one package.
What works
- Bluetooth is built in, with no dongle to buy
- Continuous MPPT tracking of panel output
- Supports lithium, AGM, gel, flooded and user-defined
- Overcharge and over-discharge protection listed
Watch out for
- Verify max PV voltage before wiring big arrays
- The catch
- It also costs more than all of them.
