    I currently have my battery hooked up to a solar panel via the solar charge controller. If I wanted to add current from the 110v charger that came with the 14.6 v battery, where would I tie it in?

    Charging with MPPT and DC-DC charger simultaneously

    Greetings, I'm building a solar system with 40 amp MPPT, a Renogy 20 amp DC-DC charger and 200 aH LifePo4 battery. How do I wire these up to be able to charge my battery using DC-DC charger and MPPT solar charge controller at the same time? Thanks, David
