Need help in Wisconsin...
Greetings all. Below is what 'I am working with' - its already purchased/delivered and that is what 'client' (in-laws want to use).
first off - this is an off grid, no utilities or running water property. Property has a small shack (mouse paradise right now) aka 'Staging Point'. Property has a pond and a garden. Property now has a Big Arse camper with a mini split and 30A ShorePower plug to power it.
System is 12VDC. There is a 825Ahr battery bank (comprised of 15 12V 55Ahr each Marine Batteries).
So current supplies I am need to tie in:
6 - 160W 12V mono crystalline solar panels.
connected to a buss bar.
traveling on 1/0 for 36ft.
(there are number of shut off, I am not going to mention them all).
Outback FlexMax FM80 MPPT
Into a battery bank (825Ahr)
From battery bank, on 1/0 into a 350A DC fuse and into:
AIMS PICOGLF40W12V120V 4000 WATT 12V PURE SINE INVERTER CHARGER
40A AC Service box (two space: one is 30A single pole, another 20A single pole).
30AAC runs for 148ft on 6/2 UF-B cable to a post with a ShorePower receptical mounted on it - for the BigArseCamper.
20AAC is for two double AC outlets (12/2 Romax) one outside of the shack /another inside.
there is also a power buss bar (12VDC) that connects from the battery bank to the outside of the Shack for: Water Pump (to water garden/washdown), Aerator pump (to prevent pond from freezing (winter primarily), Some minimal draw 12VDC LED sights (inside and outside the Shack), Regular cig lighter plugs for misc electronics charging on the fly...
Single ground (via two 24" spaced ground rods).
We are in NE Wisconsin, thus 'realistic light' is about 3.5hrs. So question is:
AIMS PICOGLF40W12V120V 4000 WATT 12V PURE SINE INVERTER CHARGER: has a 2-wire Generator wire and 120VDC input terminals. I am thinking on using some of that 6/2 solid copper AC cable leftovers to mount a plug on the outside of the Shack for an auto start GASOLINE generator to recharge a battery bank if/as needed???
So, What type of a Generator I will need and is there something with a 2-wire auto start/shut off that is not a million dollars (basically an automatic transfer switch) to kick in for battery recharging via AIMS unit?
Supplement question: I am NOT an electrical engineer by trade , does all of above line up sounds solid?
Noone will be using camper full time, however, there might be periods of 2-4 days every other week or so when either AC or Heat from that Split system will be used to occupy it.
12VDC aerator pump is connected both on a timer (kicks in during the non-light periods via a timer) and a diversion load during sunlight times.
12VDC 5.5gpm 60psi pump operates 2hrs daily during May-October as a means to push water into a 4-outlet timed valve for 225ft (pump in the middle of this run) to water the large straw bale garden. Garden is surrounded by the 2-row electric fencing, however, it was more feasible just to connect it to a single deep cycle battery and run a 25W chappo solar mainanier panel right into it (without charge controller) to detract wildlife from feasting on the veggies.
Thank you in advance for any and all input.
