Bleepin' Reddit, ate my post because I wanted to put a bleepin' link in it.

I live off-grid and have built out two separate solar systems, one is a 12VDC with a single 100W solar panel and 400W turbine connected to a single deep-cycle marine battery (approx 150Ah), which runs one pressure-activated water pump for the house taps and toilets. The solar panel runs through a 20A charge/load controller, as does the pump itself. The turbine is self-regulating and auto-braking if it detects the system is sufficiently charged. ETA: The turbine was a second-hand gift, which is why the voltage disparity exists. Getting a 48VDC turbine is on the long, long list, but it's LOW on that list.

The other system is 9 pairs of 350W 24V panels run through a 60A PWM, into three strings of batteries for a net capacity of about 1250Ah of storage, thence into a 10kW inverter to run the house "mains" power, with a fairly standard set of loads. Fridge, TV, microwave, dishwasher, lighting.

The question is "Can I use a DC to DC Step-Up Converter to connect my 12VDC turbine to my 48VDC system?" Not directly, of course, that would absolutely ruin the turbine's built in sensor system and be useless, but through the load controller aspect of the 12VDC charge controller and into the 48V batteries directly.

Am I barking up the wrong tree? Is this actually a reasonable idea? If it is a reasonable idea, do you have a recommendation on DC-to-DC Converters? I'm linking a couple I found, are they reasonably good?

Will the converters regulate draw? I know the load/charge controller will do so to an extent, but I don't want to completely drain out the 12V system if we have a couple days of no-sun AND no-wind conditions. I can live without my TV, without water for the toilets things get very unpleasant far too quickly.

UPDATE: I've gone ahead and bought the daygreen unit.
