¿can i Use the MPPT Controller without battery?, for a load powered in 24VDC

Can I use the MPPT Charger as DC-DC Converter?,it will be for loads powered in 24VDC.

So:

We will connect in a MPPT Charger PV terminal as Input DC Voltage range from 43 to 56Volts

In the battery terminal we will connect our loads in 24VDC.


I hope to have your support soon

sorry, I dont understand your last answer.

if the input is powered from solar panels and the output have a 24V battery plus loads, it will work as a standard system, why did You say that it is not what you make a product for¡¡¡¡, please could you explain me waht did you mean??. ..

if its not a super small battery; then yes, it will probably work.


The point I'm trying to make is that we design and test the product for situations with a reasonably sized battery.


And not for no battery, or having only a super small battery just because thats necessary.


The battery is more than just a reference, its there to create (voltage) stability.

I got It,

How we can know, what is the minimum AH battery that we can connect??, Example: MPPT 150/60, Is it ok with a battery in 30AH??


BR, Jorge G

I'd expect that it would, yet. But it will depend on the size and the type of the load.

I'm really sorry, but I'll never give a straight yes/no answer to these questions. You'll really have to try yourself. Perhaps if you find a good quality distributor, they let you try with a unit at their warehouse.
