Control charger watts?

[1Watt]

I have grid tie solar at my house with no battery.

Using a CT clamp i can track how many Watts I'm exporting at any given moment.

Id like to use this excess power to charge a portable battery (eg a 12v 100ah LiFePO or 24v pair of 100ah batteries). Is there a charger that will allow me to actively control how much current to draw from the 250VAC supply?

I found the Victron 24v charger has Bluetooth control and allows you to select between two current levels. I can automate this easily with an Esp32 microcontroller.

However, its not a granular solution, pushing a variable current through an MPPT or PWM solar controller would make more sense but i lack the electrical engineering knowledge to figure out how to do that.

I guess im trying to simulate a solar panel.
