SOLAR PANEL REPLACED BY A POWER SUPPLY

I have an MPPT 75/15 solar panel controller attached to a 100W (12 volt) panel for recharging a 100 Ahr AGM battery.

Can I “substitute” this solar panel with a 24 volt 6.5 Amp DC power supply. (AIMTEC #AMESP150-24S277NZ)?

The objective is to take advantage of the performance of the controller to recharge the battery when I am not using the solar panel.

Yes, you can feed the solar panel input of your 75/15 mppt solar charger with a DC power supply up to Max 15 Amp X 12V = 180 Wh and charge your battery.

24 V X 6.5 Amp = 156 Wh power, as long as this power is 156<180, you will not have any problems, but this power supply must be a fully rectified DC power supply.

Great!

Many thanks for your answer!

The ripple & noise figure for the power supply is 150 mV p-p; from then I will be OK for this application.
