mppt vs pwm
Hi, A nice little video comparing mppt vs pwm with the batteries in bulk mode. mppt vs pwm

Hi jrnymn,
I use the 1200 watt water heater when I have "solar to burn". That puts enough of a voltage drop to get me into bulk/mppt mode. Solar to burn = less than one amp of charging in good solar conditions.

PT,
Yes, but I'm asking whether a heavy load on the system is even required to kick the mppt "back into bucking mode". Seems to me, unless one has a rather large array in relation to their bank, bulk (and thus bucking) would occur very deep into the charge, regardless. I often read, mppt only applies in bulk, but if amp tapering doesn't happen until that last few % of soc, then it's kinda irrelevant, isn't it?
