Hello all.

I haver a HLG 600w V1
I was thinking on plugin them direct to solar panel. Does anyone try to connect quantum boards to solar panel?

Thanks
I wonder if you give them a call if they'd be able to answer that question I think I might do it just to see I've been thinking about going to solar power system 1720620906068249383514.jpgthanks for asking the question sorry that I have no clue about it :hump: :peace:

I've not used solar but something tells me its not really usable raw power it's more of trickle current into batteries which an invertor concerts the dc power from the batteries to ac power for use?
Hello.
The idea, was to take out the drivers, and Run them direct connected to the 4 boards.
The only thing that i dont know is the volts they need to fire up. The driver is 54v.
There are solar panels that output 42v. Whats the minimum voltagem for the quantum boards V1?

You would have a hard time keeping the output of the solar panel constant and correct for the LEDs hookingg the solar panel direct to the light. @Star Dog had it right, solar panels to batteries, batteries to an inverter, plug the driver into the inverter. You could possibly engineer a new driver to work straight from the batteries and skip the inverter, but a driver would still be required.

42 volts out open circuit. Still need to store Ah's and regulate voltage. Not as simple as you think. Plus drivers have important built in protections.

Hey bud, if the light means nothing to you sure go for it assuming its safe, if the light is important I wouldn't but that's only based on not expecting it to work properly, it might give of light but there's more to it to run it properly.
Check out this video from @Rocket Soul regarding another hybrid attempt lol

Good luck to you though

Meanwell HLG series has integrated DC power input (along with a fair few other drivers), nobody needs to engineer anything here really. DC batteries to AC inverter then back to DC thru driver: theres several layers of conversion and efficiency loss built into that, ideally find a way of working of the DC from batteries.

I know there some whove made this work but i dont know at what reliability.

That vid is so funny, his futile attempts of killing his brand new quantum board (this in a time when these where scarce at HLG and getting one to destroy it was just like blasphemy)
I seriously suspect HLG of engineering an adamantium quantum board for LG for those tests, 600w thru one board is like 2 watts per diode.

Yes, you could build a circuit from a battery to the leds to keep the voltage constant, but that was not the original question. The question was can you power a quantum board direct from a solar panel, I said it would not be ideal. Your light would change intensity constantly with the sun movement, clouds, etc. Yes you could make it work, I wouldn’t try to grow a plant under it, but that’s completely up to you.

On the manual, says:
INPUT: 90 ~ 305 VDC. 127 ~ 431 VAC

Do you think i can power the driver HLG 600H B direct to a string of solar panels that outputs 90 ~ 305 VDC ?

Thanks

You have ac and dc backward, it’s 90-305 AC, 127-432 DC. Yes you could drive the LEDs direct as an experiment. Todays solar panels put out about 20w per sq ft. At 12-24VDC. So if you put 12 12VDC panels in parallel you’d have 144VDC, 1’ panels would give you 240 watts. To drive a 600w driver you’d need 36 Sq ft of panels, 3 sets in series, not bad. Now it will only provide that much power during optimal conditions, so clouds, you need to double the solar panels, and no light when dark. My question is if looking for efficiency, why not just put the plants outside or in a green house? You loose a bit of efficiency charging batteries and using them to power the driver, but batteries sure would make the setup more useful.
