efficientPV

SMPS generally work down to 60V or less. Below that they will bump unless the startup resistor is changed. I have one that works down to...

I use switching power supplies to power 12V fans. I think it is elegant. You get full isolation and if the supply shorts it won't...

There is the next generation of cheap 12V inverters that will shutdown with low voltage and start up again when voltage returns. These...

More internet garbage. The diode is backwards. And just what is he running? Solar panel voltage will be ok for many switching...

Looking at pictures of the lamp, why are the probes connected? Current is thru the clamp. Connect brown and blue together and also...

Not likely at all.

Are these bulbs really cheap. Your inverter is putting out some HF noise and the capacitance of the cable is enough to supply power to...

Unfortunately, these are not a thing. I do it by looking at PV array voltage and proportionately diverting enough power directly from...

Try putting it on a 100 foot extension cord.

I use an OP101 to look at pulses from LED lighting to determine how much flicker there is.

Try this, put a voltmeter between the 48V power source and the light and measure the voltage. Depending on the constant current circuit...

Many SAE connectors are reversed depending on use. I assume yours are backwards.

It is a very simple solution. About impossible for anyone here.

Those diode videos are of the wouldn't it be nice variety and are in no way practical. I do wish they would get across the idea that...

Schottky diodes typically have low forward voltages up to about 40V rated inverse voltage. Forward voltage is also lower when they run...

Why would you want to use a Schottky diode.

have one of these and it is probably just what you want...

One will take over and the others will think they are in float. There are controllers designed to be in parallel with one decision maker.

I use resistance heating with my HPWH. That and other modifications are just too exotic for most here.

I have extreme shade and run multiple strings in parallel. I used to run three controllers because I had strings of multiple voltages...
