@ CDN VT if the drawing is not up to your standards then look somewhere else.  I don't remember pointing a gun at your head and requiring your input or help. you got nothing better to do than go online and make judgments about other peoples work?  go watch some more porn.



With this attitude, I suspect you rub everyone the wrong way as a matter of course and cannot get local help for that reason alone?


Tom

wow, so someone bashes me online and then i am the one with the bad attitude?  not sure how you came to this conclusion? 

did you not read the post he sent my way?  how is that considered world class help?  if i helped people like that i seriously doubt it would be considered world class.

my opinion on respect is that if you want it you should learn to give it.

i have never started a post or discussion on this forum that put anyone down or disrespected what they said but i have been made fun of more than once for not being up to the "standard" of the people on this forum.

respectful VIP treatment for sure.

not trying  to be rude or anything.  just returning to sender.

have a nice day

I will respectfully disagree with you a bit on circuit drawings Tom.
There are schematics,  ladder diagrams, pictorial  ( which this one falls into ) and some often  weird cryptic wiring  diagrams I see on certain devices. They all have their own purpose and uses.
If this drawing accurately portrays the circuit it is as valuable as any others in my mind. It also includes information like distances, breaker sizes , SSR type,  and wire sizes.
I have worked on a lot of devices, appliances, and electronics and it can take some time to basically do what his diagram does - isolate the one circuit and control that is being studied. Sure there could be other things that will come into play but other than detailed photo's or an onsite visit it would be difficult to take it all in.
We all learn from our mistakes - at least I have . The next job I do is usually better than the previous . And let me tell you I have made some real wiring tangles in the beginnings - especially before internet when I could publicly post up those messes for critique .

thank you sir.  all i can do is try my best and always strive to do a better job than the last.  we all are learning at some point.

thanks again for all the helpful input and comments to my questions.

Kauaisolarman,

All of the info you need on wiring a water heating element, SSR, SSR rating, spike supressing diode, diode type etc has been well covered in previous threads on this forum.
I'd recommend you search and study those threads.
Otherwise, with respect, you are driving a never ending thread, asking questions without providing the details of your system, the exact devices, exact wiring and photos to show everything.
This means people are answering as best they can then you immediately ask another question and it goes on ad nauseum.
You appear to be behaving as a troll, when you get criticising answers you fall back on the excuse of being a beginner and trying to learn,  solution go buy a book, hire someone who knows what they are doing, find a course at your local college.
I hope you get your RE system sorted out

yeah.....

i though the forum was for that..

asking questions and getting input and answers.

if the forum was only for fully educated folk that read all the books and have all the knowledge that needs to be had then why even have the discussion in the first place.

Funny how you people are quick to criticize someone that asks a "wrong" question and the act as if you know it all.

sucks because when i started posting here i thought the members would be a little more courteous and mature about dealing with newbies and people that were not as knowledgeable as they were on the subject matter.

I guess this is like any other forum with know it all people that always reply the same way."use the search"

for your information i have read through all the threads on the forum discussing using a water heater do divert excess power i have also read other forums as people have pointed me in that direction.  thats how i learned to wire up what i have in the first place.  problem is the information is obviously not complete as it is clearly not working the way the forum and other posts described that it would.

the problem/issue that i am having is specific to my system and setup thats why i brought up the questions in the first place.

WHY ARE YOU EVEN POSTING IF YOU ARE NOT HELPING ME ANSWER MY QUESTION AND HELP SOLVE MY ISSUE.  WHY DO YOU FEEL THE NEED TO TELL ME WHATS ON YOUR MIND AND HOW YOU THINK I SHOULD POST THINGS? ARE YOU A TROLL?

sorry i am not a internet forum guru or specialist so i dont even know what a "troll" is.
all i am doing is asking genuine questions and hoping for genuine help.

makes me hope that if one day you want to learn to do something that i know how to do and you have a question for me i cant wait to call you a "troll" and tell you go read some books because all the information to what you are looking for is already out there.

this is my last post and i wish good luck to anyone else that wants to use this forum for any help.

all you get is criticizm and sarcasm. from these "know it all" superusers that have read all the forum posts and know all the forum answers. 

i though the midnite solar forum was for midnite solar customers that needed help with their products.  i have purchased 4 midnite classic charge controllers and over $2000 in midnite solar accessories and this is how i get treated?

great stuff

better look somewhere else.  or "read a book, hire a professional, take some college courses"

maybe i can get better help from somewhere else anyway.

this forum sucks

You have been given a lot of help - there are 4 pages on this thread alone.
I am no expert with SSR but have spent a bit of time looking stuff up to answer your questions - and as DGD has said I have read and learned a lot about SSR in past discussions on this forum ( some are your own that were answered in the past ).

If I summarized the suggestions to fix your problem that has already been given in this post is -
Spend the $$ needed to get a good quality SSR  that can handle PWM, heatsink it properly, and install the correct diodes.
You said you have contacted an SSR manufacturer and they will provide you all the parts that are needed to do the control you want to and they will back up their product.

I think you have done some good research and work in putting together your system from what you say , but I also see how it is frustrating for the experienced installer on here since it is so difficult to provide detailed answers without an onsite visit or detailed photo's of the whole system wiring.  Everyone could talk and suggest till they were blue in the face but a person there might immediately see - oh look at that - there is the problem.

So everyone wants you to find a solution and report back when you get the proper parts to do the job correctly .

These forums are volunteers giving advice and not employees of Midnite ( sometimes they pop in ) . So don't associate criticism of your posts here with Midnite the company .  It does seem like your last post you want to bite the hand that feeds you !
