Add AC charger

[horseplay]

Is it ok to add an a/c charge controller to a solar charge controller + lithium battery system?

Also is it possible to add a repurposed laptop charger + mppt solar charger to the same?

How about a switch to change the source of the existing solar charge controller to the laptop charger? What kind of switch can be used?

Thanks in advance.

Charging from multiple sources

One can have as many independent charging sources running concurrently as they like provided they are programmed properly for the voltage of one's battery bank. Examples (some or all at once, even multiples of a single type, different brands, etc.): Solar PV via MPPT Solar PV via PWM AC-DC...

I got lost when the laptop charger showed up, in the question.

I think he meant a ~18-19V laptop charger as input to a MPPT.

Yes. I have a laptop charger about 60W that can feed into the Solar MPPT/Charge Controller. I tried it once it worked. I just found a knife switch in Amazon that should allow me to switch the source.

My battery in the trailer is almost always topped off by the solar panels but it has been raining for the last few days. Guess I still could use some A/C charging.
