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 ...

Starter questions:
Should I avoid PWM, is it a dead technology?
If I get MPPT, does it not matter AT ALL what voltage a panel is? E.g., could I use a 30-40v residential panel? Would that have other drawbacks? Wire size? Sturdiness?
Are these the telecom batteries y'all talk about? Are his 145aH Dekas ok?
What do you all think about 2 of his Dekas, plus my current house battery (AGM, unknown vintage, nominally 150aH but probably not that now, I am afraid to test it because testing killed its twin, runs all my non-freezer non-shaveice loads without batting an eyelash.)?
And 1 or 2 225-300watt used panels?
