Arduino Solar MPPT battery charger

Its quite possible that there simply wont be enough power available to provide the bulk charging and equalizing currents
when you want them..

I think that's a question of do you have enough panel, not how to charge.

PS: "When you need them" does not apply to equalizing... this can be done every 2-6 months as time & energy allows. (less frequently the better behaved your system is on your batteries)
