1) If you want to expand later, you'll either be replacing all your components, or buying capable enough components up front to handle your eventual needs once more batteries and panels are added; I would be inclined to the latter.
YAHTZEE!! Given my current finances that's how I'm going to have to proceed.
And DAYEM them Go Powers ain't cheap either!
And yes, LA batts are going to have to do me for the foreseeable future until I can upgrade. The plus for them is they're cheap and I can stash them and put em into service when the old bank has dropped off in performance. Sam's has Duracells for ~$85 each. Oddly enough they have a MUCH better Amphr rating than the other more expensive ones.
Thisun is a real cheapo, I know, but it does handle 24 vdc. If it holds up for a year I'd feel like I got my money's worth and could save up my kopeks to get a better rig. And if it doesn't puss out on me I could always use it for speriments on the vawt rigs I want to tinker with.
This one might be more robust and the input & outputs can be customized. For a little more $$ they have a 48vdc model too.
Thanks for pointing that inverter voltage out. I totally missed that. I do want to at least run 24 vdc to reduce losses at the inverter.
I don't want to return to the Little House on the Prairie days, we're not Luddites. A small fridge at least and a small to medium freezer to keep my harvested chickens ( many of which can be harvested as needed), pork, beef & homemade dairy and produce-some of which we plan to sell- that doesn't can or dehydrate to our tastes will be needed. When friends and family come to visit I don't want them to even notice there's no grid involved until I tell em. What they will notice is the absence of a ton of useless gadgets.
I do agree with only cooking what you need for the day. Processed foods? BLECH!!! They will be banished from our larder. As we expand our food production we'll start making our own ketchup and mayo and BBQ sauce, the sauce IS the boss, ya know.
So can I assume the Renogy controller is a reliable unit? If so I'll get my first component on order right off.
