I happen to have an old PWM controller (Sunsaver 20L) from my old camper set up. I now have the 2 BB batteries with MPPT controller. I have an old 160 W panel, the frame of which was damaged by my stupidity but the panel still works. i have a saw mill shed where I use a 12 V winch to roll the logs on the mill and a 12V fan to keep the black flies at bay.
My question comes from being cheap... okay frugal ... in wanting to use what is handy to get by.
I was going to buy a cheap 100Ah LiFePo4 battery (recommended by Will Prowse) to run things at the mill, using the beat up 160W panel. I know that a MPPT is made for the LiFePo4 batteries BUT could I "get away with" using the PWM controller? I am not looking for performance but I also don't want to start a fire!
