Is MPPT a DC-DC converter?

A MPPT (Maximum power point tracker) is an electronic DC to DC converter that optimizes the match between the solar array and the utility grid or battery bank. This converter help to convert a higher voltage DC output from solar panels down to the lower voltage needed to charge to batteries.

Can I use a solar controller as a DC to DC charger?

you can do it, but if it gets unplugged the solar charger will continue to draw power from the battery, so its not a great solution for unattended maintenance..

What is a DC to DC converter and what is an MPPT device?

A DC-DC converter is a general-purpose device to convert one DC voltage to another, e.g. 5V to 12V so that a computer board can have an RS232 interface without needing separate 12V power supplies. An MPPT controller is specific to solar panels, adjusting the current drawn from the panel to give maximum power output.

What amp DC to DC charger do I need?

Finding the correct size dual battery charger So, how do you know which one is right for you? As a general rule, battery bank sizes of 75-200AH require a 25-amp dual battery charger and then for higher capacity needs, a 40-amp dual battery charger is recommended.

What’s the difference between MPPT and PWM?

MPPT stands for Maximum Power Point Tracking. The main difference between PWM and MPPT charge control devices is that the MPPT devices are more efficient. MPPT charge control devices have 30 \% more efficient in charge efficiency according to PWM type. Panel voltage and battery voltage should be matched in PWM systems.

What is a solar DC to DC converter?

A DC-to-DC converter or a voltage regulator is a device or circuitry that converts a source of DC from one voltage level to another. Most solar systems come with a special type of component that is able to convert DC to DC.

Is there a way to get a constant output voltage for MPPT?

\\$\\begingroup\\$Yep. If you want to have an MPPT with a constant output voltage, you’d need to have an intermediate energy storage (such as a capacitor bank) after the first DC/DC converter, and then place another DC/DC converter after your energy storage.

Can I charge a 12V battery with a victron MPPT?

A Victron MPPT needs PV Voltage to be +5V higher than Battery Voltage to start operating. If you want to charge a 12V battery from a 12V battery, there will (should) never be 5V difference so it will not start charging.

Can I use a MPPT to power an alternator?

A vehicle alternator has its own voltage control mechanism, making it impossible for the mppt to work properly. You can use the Victron DC Buck Booster for this. That should work.

Is it possible for a MPPT controller to work properly?

So long as the MPPT controller doesn’t attempt to draw excessive input current, i.e. use a lower-rated MPPT controller, then I’m puzzled as to why it’s “impossible to work properly”. this thread is very old now.
