Off grid cabin. Solar setup.
Sammconn:
Ok, it appears I didn't start this yet so here we go.
My cabin is on an island in the middle of a fair sized lake.
Which means no utilities at all.
We've been running as it was when we bought the place until last fall.
I purchased 1 kW of solar panels, charge controller, inverter and other bits.
The original was a hybrid of a 12 volt battery, 120v modified sine wave inverter, generator, windmill and some solar (40 watts).
Now as of this morning I have an even more hybrid setup.
I have opted to keep a 12 volt system, as we have 12 volt lights, and he windmill is only for 12 volts, so it would be a lot of work to decommission it right now.
Then there is the new 24 volt system. It is tied to the 1kW of solar panels, 50 amp MPPT charge controller, a 3000 watt pure sine wave inverter and a 24 volt smart charger. (Charger not connected yet, as I need to re run some dedicated generator circuits.
It was an adventure splitting everything out so as to not ties anything together.
Spent some time looking at how it was wired, and found the source cable, and it was easy from there.
I'll have to sort out my pictures at home. Signal is poor at best today so no uploading.
I'll find them from back at digging the trecnch, to today.
FWIW, did a little test once it was up.
Ran the 1400w microwave and coffee maker, along with the normal loads.
No issues at all!
Was in the 26xx watts, with 122.3 volts on he display!
More to come when I have time and signal.
Sammconn:
So this all began last summer, I purchased all the parts I needed.
Batteries: Trojan T-105, 6 volt golf cart cells X4
Inverter: Samlex PST-3000-24
Remote: Samlex RC-300
Connection Kit: DC-2000-KIT
Charge Controller: ProVista 50 amp MPPT
Charger: Lester Electric 24 volt 25 amp
Panels: 265 watt X4
Sammconn:
Late last summer, I planted the cable and built the panel stand.
I had the cable in the ground, but not totally buried back, and we had some snow...
As the day progressed, the snow went away, and the mud came out.
I put the basis of the panel stand up.
Brought the underground up to the junction box area.
Sammconn:
With the stand built, the panels were added.
They are large.
The rack is around 14 feet wide and 5 feet tall.
Then connected up the panels.
I am running two in series, parallel to the other two.
And have reversed a small breaker box as the panel combiner.
Sammconn:
With the outside work done enough for now, I ran the cable into the cabin, and into a fused disconnect.
Tied in the charge controller.
And powered up to see what we have.
This is the input from the panels:
