Weekly Questions
Im wondering about something said in the specs saying that these LED lights can only assist in the flowering and fruit cycle?does this mean...it cant be used as the only source of light? Thanks!
A:The LED lights can also act as holiday light, since they are very safe and energy efficient. We also have some white LED available in our store.

Q: I plan to build a wind/solar system that will produce more than 1000W. The DC motor has to deliver around 130V to deliver the wattage that its rated at. Can the SSI-200 grid tie inverter accept that level of DC voltage?
A: The voltage range for the inverter is 16V to 30V.
 
Q: Hi from new zealand. in a hi wind area.....140 km, Will the 8 blade setup be noisy as hell and recomended? Or should I stay with 3 blade?
A: 8 Blades is for low wind areas. If you have high wind I recommend using 3 blades as You will get more power that way.
 
Q: Does 550W wind generator have a way of braking itself in high winds?
A: You will need to short the positive and negative wire to brake. Or you can consider getting a charge controller to do the braking.
 
DC to AC
Grid Tie inverter can convert Direct current into Alternating current ( DC to AC ). They normally change the voltage level into the North American standard voltage 120 or 240 VAC. Such voltages are useful for every household appliances. You can even sold back any extra electricity back to the power company.
