You can't wire solid state relay in parallel, but can you wire these in parallel since controlling the state through code, or still not work? Thanks!

Relays should not be paralleled, as you can't guarantee simultaneous activation, so one relay would handle the full current. MOSFETS can be paralleled.

Steve Spence was right, there is no way to get them to switch at the same exact time, there will alway be some form of delay between them.

Yes but use a relay. I did and have no issues. Amazon sells a pack of 5. 30amp already prewired for cheap and the worked perfect.

you connect the 2 timer in series or parallel? (if series the timer front and back in the circuit may cause the on off problem) You are saying the timer can not switch to auto and the manual function also not working? Had you check your supply at the timer terminal is it connected correctly? The timer activation time "on" and "off" is set correctly? Do you set it to be turn on and off on specify day or everyday (need set and select day/days)

In a word, yes. A simple setup with your circuit connected to the relay. Just keep in mind the maximum amps that the relay can handle for AC/ DC and your circuit must supply its own power.

I would be concerned about burning this up with so many amps pushing through what looks like a pretty small component. However it sounds like the idea here is for this to be the wireless bridge to a separate relay so depending on the specifics of that other relay as others have described here and it can handle the power it should work. In addition to that, in an ideal setting, your control logic software should have a routine for confirming startup and retry after failed start.

Yes, you'll need a large relay. This has output for a Solid State Relay. Depending on your voltage, you'll need a very large SSR and heat sink for 15Kw. Consult an electrician or a competent engineer if you're not totally confident in the entire setup.

Generally speaking, switching power supplies can NOT be hooked up in parallel for greater current unless they have some kind of balancing communications bus that is designed for this. What typically happens is one power supply creates a slightly higher voltage and it ends up trying to carry the load of the entire system and then burns out because the other supply was never sensing enough of a voltage drop to change it's period to allow more current. Then you have a new scenario with a single supply that cant carry the load and it burns up. When you put power supplies together that aren't designed to be used together, they often both blow up. Qualifications: I've let out the magic black smoke on more than one occasion. The Internet. I work in a lab full of EEs that tell me it can't be done without some kind of sharing function.

This was a failed project for me, one of my 2 controllers died, There were times one of 2 lights worked. I might have my controller on one side of my 220 line and the sockets on the other side. What I can tell you is that manually turning the lights on with the switch in the garage, they don't come on. I think "Francois" has answered the question for us. If I saw his thoughtful answer before I started to respond, I might not have replied. Thank you Francois.

Yes. I read somewhere where it will show somekind of code error if you dont use. I got tha relay harness and installed it and couldnt get but one high beam to come on and no low beam. Took it back off until i have time to fool with it. I think tha problem is me tho.

As long as you have a way to reset it. It is a time delay on relay so when it gets power it does not turn on the load until the time selected delay is meet. You would need 2 timers and a relay with N.O. and N.C. contacts to make the circuit work.

I'm a little unsure of your question but by "these" if you mean controllers, I would assume you have solar panels exceeding the 40 amp capacity of a single controller. I think you could connect any number of them you wanted to in parallel each controlling its own set of solar panels. At some point I suppose you could reach the limit of your battery bank's ability to accept any more current though.

Pretty Simple. There is an input VCC and Ground and once that power applies it waits an x amount of time (based on the potentiometer) to actuate the relay. The relay has a COM (not connected to Ground) and a normally open and normally closed switch. Anything specific that you need help with?

I would recheck the connections, and then the relay. You could swap the other relay if it's working properly.

Alan,Wish I could help. After spending an hour with my Fluke I wasn't able to figure it out. I spent more than an hour (no joy) searching for the wiring diagram before resorting to the Fluke.I ended up using only the AC IN jack - bypassing both pwr switch and fuse.Kind of a bummer. Good luck, man.Steve

Yeah I had that in my fan info too. But the info with this control says not to use it with a solid state fan. Who even knows what these "solid state" things are. You should be fine.

You can think of out 1 just as a relay. If you want to use a voltage controlled sold state relay it won't work connected directly. It should work with ssr-va relays when wired properly. I had an old ssr lying around, so I used an old 5v cell charger for the control signal. It was easy to wire it to the same power as my pid, so it works whenever I plug in the unit. Good luck!!

I do not have them on the same circuit. For me, it works but the transfer rate is slower than when they are on the same circuit. I cannot tell you whether that is normal behavior, or just a function of the wiring in my house (some of which is 50+ years old).
