That site has lots of useful information, but what I am trying to accomplish is not normal for them- any solar wind generator system would normally be used in conjunction with batteries, which for my on grid use are not warranted or desirable.
OK, you have a glorified battery charger. That manages itself when battery voltage gets too high. You could use several rechargeable D cells to trick that part of it, and then you need to be able to disconnect the load when generation is not able to maintain battery voltage above some minimal voltage level. Not rocket science but you need a decent current capability switch and ability to compare voltage to an on/off threshold. You might not even need a battery, a large enough capacitor might be enough to smooth out the alternator current pulses. In fact with a large capacitor instead of battery it wouldn't be damaged by low voltage so, no wind, no heat, no problem. I would be tempted to also add a temperature sense to disconnect heat when not needed but a simple mechanical switch can do that. What happens if you just connect the load to the system with no battery? JR
Using batteries is not an option, as when the wind dies at night the load would drain the battery...
Just to be clear, is the 10A battery charger just to start the generator working and wind can hold the load up after started, or must the load be getting 10+ amps continuously for the wind generator to add on top of that? JR
Maybe I'm missing something, but wouldn't a simple blocking diode solve this? Even cheap solar kits include them, to prevent current from flowing back from the batteries at night.
Seems like what you need Art s a relay to open the load ( the heater ) from the battery when the turbine isnt turning (no wind).Attach a cheap deep cycle battery as normal, attach the heater across it as normal, then gin up some way to sense when the gen is charging - those status LEDs and a photo sensor possibly, or just a comparator circuit to sense higher than dead battery voltage, open the load relay when the turbine isnt turning.So in essence the heater only works when the turbine is turning.Maybe?
