Stupid battery and solar questions
I figure I am going to have a lot of them, so I better put all in one thread :B. My situation: - I mainly want solar for running residential freezer and fridge, maybe also for charging my shave ...

Should I avoid PWM, is it a dead technology?
It's not dead, but the choice PWM vs MPPT will become clear once you've decided on total panel wattage.
If I get MPPT, does it not matter AT ALL what voltage a panel is?
No, but total Voc of array shouldn't exceed maximum input voltage that controller is rated to.
E.g., could I use a -40watt residential panel? Would that have other drawbacks? Wire size? Sturdiness?
40W is a maintainer and hardly needs any controller. Decide on TOTAL wattage. Your energy needs listed in the 1st post should be quantified with a proper energy audit. Without numbers of AH usage you won't get accurate estimate of needed solar wattage. Might as well toss a coin
Are his 145aH Dekas ok?
Battery bank depends on solar wattage and energy needs. Energy audit first.
