Is this driver right for my boards

Is this driver right for 3 of these boards?

I plan on growing in a 2x4

It will work, but you will only get about 190W of draw with 3x 30V boards at 2100ma.
30V x 2.1A= 63W per board.

That driver has 115V total, available for a series circuit. So you are only using up 90V of that with 3 of those boards. A fourth board won't "fit" on that driver, to get it to its full potential.

Make sense?

So I should get a higher driver with more volts if I went with 4 boards il need to get one with 120 v to be efficient

if I run 3 boards of a higher driver then 90v then add one in future (next month payday)would this effect the 3 boards at all? Cheers for the help

Hlg320-2800b for series wiring.
Would this be a better solution, il have 4 boards but 2 different boards here’s the links to them both, all the boards come to 108volts - many thanks :eyesmoke:

Shit good you asked, look for an hlg 320h-c2800a instead, download the spec sheet and read it, its been a while for me.

No I wouldn't ever run different sized boards in series, not unless they have the same chips & chip count, you could run them in parallel but you cant go beyond 24v, so the 150 model will be bottlenecked, if you do this you should fuse each board at 3a.

Honestly my opinion would be to use two separate drivers per pair of 120/150.

Would 2 of these do the trick

remember when driving board above a certain wattage they may require heat syncs
Yeah i just reach the limit luckily at 2800ma the max volts is 30 per bored.
Planning on making a double bored for the start as could do with waiting till pay day to buy the other half would this be fine to grow weed in a 2x4 for the veg then when they flower il have more lights?

Having two boards with different voltages makes it more complicated.
The xlg 150 h has a range and I don't think both boards will fit that, though im not positive because they do have more features than HLG drivers.

I would play it safe and go for a HLG-150-24 and a HLG-150-30 wire the boards in parallel
