Wind / Re: Block diagram for our turbine
« Last post by kitestrings on February 24, 2024, 09:17:29 AM »Nope. We're off-grid.
I didn't show our PV (3.2 kW) system or any of the end-use side of things in the above diagram. We have the two Classics for the turbine, and we have an older Outback MX60 that contributes the solar to the same battery bank. For AC loads we have just an Outback VFX 3648 (48VDC, 3.6 kW, 120VAC), and our Onan (4.5 kW) for back-up. I'd always thought that we'd add a second OB for 240VAC, but it just never seemed necessary, or worth the effort.
I suspect a connection to the grid would just be a limitation of the inverter used.
Here's where our system is a little weird -
We started with a very modest 12VDC system (circa 1985). When we transitioned 48V we kept much of the existing 12V lighting. I added a 60A, 12VDC breaker panel (Square D breakers are rated to 24VDC). So, we have a 12V tap with a Solar Converter equalizer.
Our water system is a 24V Sunpump submersible to a cistern, then a 48V vintage F E Myers piston pump for pressurization.
We also have two small step-down converters: one 48/12VDC for the fridge, and one 48/24V that supplies our freezer and submersible.
I'm by no means suggesting anyone else should adopt this approach. As I think you know though, things evolve differently over time than they might otherwise if one started from scratch with all future objectives known, or better predicted, and without the financial and resource constraints most of us start out with -
Sorry, more than you asked for. Let me know if you have any questions about the Classic's. I'd say they have worked well for us.
Best, ~ks
