Figure out what you need before you buy damn it.

Good for you. Search this site.

Easy to find people reporting problems with Renogy components. In most cases, dealing with customer service for warranty/troubleshooting demonstrates challenges with a language barrier and frequent dismissal of user concerns (nothing wrong, not our problem).

Generally speaking Renogy is marked-up cheap Chinese stuff with inconsistent customer support.

Amazon reviews on the items for sale confirms this. People receive non-working or failed components and can't get them supported. The common theme is "they just don't answer the phone". Worse, it seems returned items are resold without confirming they are in working order. People will get the same defective product(s).

HQST is another brand of Renogy.
At one point I was going to drive out to their retail store here in CA and buy some stuff. Now I'm glad I waited. I think they closed that 'store'.

You pays your monies and you takes your chances. :giggle:
 
Is it sad that I've had better support for my PowMr controllers than people have had for their Renology? PowMr actually responds to my emails and gave me a few tips early on.
 
Other than reading the complaints of others (Im not saying they aren’t real), what specific issues have you had with Renogy?

Go to Amazon and look up any Victron component. You can find bad reviews and complaints.
 
I have a signature line on the Hvac forum I use…

When the boat repairman estimates you need to fix the holes in he boat to keep out the water, do you insist on a larger motor?

Meaning, know what your issues are… don’t just buy stuff.

Look at the posts on THIS forum. There are only a handful of Victron failures.
 
That's one thiing that forums like this tend to do, distort the impressions of various products. It's just a basic fact that people often come here with issues with their products, those products tend to be lower quality / price, and the names of those products are all over the forum.

There are a lot of top grade products that are only rarely seen mentioned here. It's not that no one is buying those products, it's just that the people buying them aren't having issues for the most part, and therefore aren't creating discussion threads about them, they are just working.
 
If I waited to know more than I don't know I'd never do anything. A bargain you wouldn't mind sitting idle in the garage twenty years can focus your thoughts. When starting, there's nothing worse than a blank sheet of paper.

I'm the opposite. I love a blank sheet. There's so much potential. So much to learn. So much to figure out. That's my favorite part of any project. By the time the sheet of paper is full I'm getting bored and I'm ready to move on to the next project and learn something new. I have such a long list of unfinished projects because of this. I'm still amazed I actually finished the trailer I'm now living in and typing this message while camped in a national forest for a few days.

And I think that's the key here. Have the paper full BEFORE you start spending the moneys!!

To add to the rant, come on people! Why do so many people want their first project to be a whole-house-multi-building-electric-heat-air-conditioned-custom-built-battety-super-sized system???!!!

Start out small at least once to get fully wrapped around what you're doing AND what you can realistically see out of it. The "Math" says my 200w of panel is overkill for a 5w draw, but "Reality" is that I destroyed another battery due to excessive discharge due to weather (haven't seen the sun in over a month!) so a test system is vital to learning first hand the difference between "Math" and " Reality".
 
While the amount of research needed may be extensive, I suspect the average person armed with the energy audit spreadsheet, Google and that Solarbiz worksheet could conduct an energy audit and get a "75-90% plan" in place in an hour, i.e., any sizing or cost estimation could be within 10-25% of actual vs. "buy and pray" being 1/4 to 1/2 of what's actually needed or completely wrong (12V vs. 24V needed, etc.).

I've supplied those resources and some guidance to a couple friends when planning systems for their RV, and none of them took more than 15-30 minutes to get the system outline defined and be able to come up with a reasonably accurate cost.
 
Not only that, but once you've listed what you 'need' and what 'would be nice to have', you can differentiate between a minimum to cover the needs and decide how much more for the 'nice to haves', and what's a priority.

The latest trend for mobile application is to run the whole thing electric. Most of the new motorhomes have a residential refer instead of a camper absorption style fridge. So you have a couple of milliamps for a board, verses several amp hours to run the whole unit. Which is fine as long as you have the supporting electrics for it. Most of the new ones don't come with a propane oven anymore either, relying on a microwave/convection unit. But we've used our oven extensively over the RV's life - even cooking a turkey in it while driving, at least a couple of times. LOL

Like the charging apparatus of old being obsolete for lithium, many of the systems and appliances don't lend readily to a pure electric or solar based system. Adapting it to existing is one thing, designing from scratch is another.

It takes a LOT of juice and consequently cost to build a system to power everything in a camper, especially if you want to run an air conditioner on it. Frankly I think people get a little carried away with it all. More power to them, hope it works out as expected. It can become a very expensive proposition. They're still selling flooded lead acid batteries like hotcakes because lifepo batteries have a relatively high upfront cost. ?‍♂️
 
Eh, most of us get some parts wrong no matter what. I've learned that about myself over the years. I find it's best to learn the flat part of the curve and then start trying stuff. Most of the advice on forums is biased and not always exactly true anyways. You don't really know your situation until you get hands on.

When budgeting I always add in extra time and money for iterations. Especially if I don't know anything. Look at the off grid garage youtube channel, he has bought tons of stuff and a lot of it doesnt work exactly like everyone says it does.

Sometimes you just have to jump in and start swimming the best you can.
 
To whoever fear their question will be criticized, ask anyway.
Yes, dumb question, smart question, vague question that you can't figure out how to formulate because you don't know enough to know what you don't know. Ask away! This thread should not discourage anyone from asking. I ask dumb questions all the time (in fact I have started multiple threads over the years, solely to organize and ask all my dumb questions).

But newbie or not, we do need to learn presearch our questions, ask effective questions, be responsive to guidance, and take an active role in our education/problem solving.

But you should know
Those bothered need not reply, please.
Many of "those bothered" (venting in this thread), are the ones I know to be among the most helpful, most patient, most engaged people when it comes to helping new people on this forum. The ones spending hours of their days helping others. Not just old dogs grumbling (though i can see how it would certainly come off that way, and does have an element of that). The OP for instance has helped many a clueless beginner (including me ;)) and contributed over 50 resources to the forum, many of which are explicitly beginners resources.

Its easy to not be bothered when you aren't encountering the same preventable, foreseeable problems or stumbling blocks time after time. But its easy to get burnt out when many of the people asking for your help have clearly done little to no research, and aren't motivated to do the tedious bits. Wanting a little hand holding or reassurance or help with the technical bits from more experienced members is totally fine and natural and what this forum exists for in large part, but you've got to want to help yourself and want to learn and to do the tedious bits.

I don't think this thread was meant to criticize people for asking questions even dumb questions, it was just venting about the frequency of people rushing to buy things before they understand what they are buying without asking questions/doing research up front leading to unnecessary constraints/. Asking the "dumb questions" or better yet searching/researching first, and just approaching a project in a deliberate manner requires no solar knowledge, and is not too big of an ask.

But yeah, I do agree, this post should just be read as venting, it shouldn't discourage anyone from asking (after searching) anything, even the "i bought xyz components how do i make them work together" questions. But hopefully it will encourage some to be a bit more deliberate before getting to that point.
 
Uhm...the noobs are NOT going to pre-read this thread before asking ANYTHING, and this forum IS their research. ?

It's a venting exercise on what happens with EVERY technical forum. Hell, the car ones use the acro: RTFM ?
They don't do THAT either.
