Camper Shell Solar

I am confrontational when it comes to trying to save people money or informing someone that what they are doing is unsafe.

For you I did not want you to build a system that was too small and I may come across as being rude but sometimes it takes being rude to wake people up when they think they are doing great but are not.

I hope that 50Ah battery will work for you and I am glad you are building a system that will provide what you want.

No, you seem to get off on bullying people into your POV. Back the F off, man, you're not making any friends.

I have discovered that unlike Battle Born, which uses the little 18650 cells, this battery uses prismatic cells, which I like much more.

You seem confrontational. It's unnecessary and honestly, counterproductive. But I have news you'll like - I have decided on two things - Ground mounted instead of roof. Also, I found a 12v 50AH battery I can afford. For the 100AH, I'll need donations.

Who said I don't like you? All I know is that a lot of hardware made in China as opposed to other oriental nations fail an early death. I just don't trust them but I applaud people that are trying to build something that lasts

Dude, they ALL come from China. As I said, it's $50 bucks. If it fails, lesson learned. But I've read a LOT of reviews from a lot of places. Most of them are good. From many countries, not just the US.

You really don't like me, do you?

If it came from China IMO you will have to replace it soon

Cheaper from China. It's only $50, if it's dog**** I'll replace it.

Depending on what you need to power that 30Ah battery may be too small for your loads and those 3 100 watt panels.

Oh and I doubt that the charger is really an MPPT at that low price.

Two channel amp, volume certainly will not be cranked (unless NO ONE is there) and not for long. Ypu know, "My Generation," or "Won't Get Fooled Again (live versions, of course). I've always dreamed of waking up to "Baba O'Riley," with slowly but ever-increasing volume to the point where the truck is shaking and the furry desert (or wherever) creatures go scurrying. Then the band suddenly stops and it's silent, again. That'd be cool.

And yes, if it's too loud, you're too old (and I'm 68).

For some reason you appear to think I'm going to be running electrical stuff all day and night. No, I am not. Most of the time, i'm going fishing. Honestly, I don't anticipate using up the battery. I mean c'mon, a couple LED strips and a car stereo with a small power amp? Efficient speakers (JBL). In summer, camping, how long do I expect to use the lights? I'll use the stereo mostly to listen to minor league baseball. I will have a single LED night light/lantern, but it will have its own battery. I am quite unconcerned.

Yes, going fishing all day means you won't drain the battery at all. But listen to an extra innings baseball game and fishing report and maybe you will? No specs have been offered on your car stereo with amplifier (50watts x 4 channels maybe?), but let's say a 5A draw since it doesn't sound like it will be cranked up or pumping out bass. 30AH/5A is 6 hours to go from 100% to 0%. This doesn't seem like your likely use, but also not out of the realm of possibility.
LED lights are probably insignificant, run them all night and not worry about them.

OK. You can measure the amps from the CC to the battery to make sure you are getting every amp it can deliver because if you drain the battery too low those panels will never get you back up to full charge. Just be careful and alert or you will be replacing that battery quickly.

Well, I've listed the loads. Very small. In addition, budget is limited. Are you willing to donate the price difference between the 30AH and the 100?

I am a senior living on a VERY small fixed income. I cannot afford what you suggest. But I looked at the POWmr Web site and actually spoken with a tech rep in China (toll-free call!!!). I am convinced, and I'm as cynical as it gets. The guy was cool.

Edit: Didn't think so.

It is MPPT. Look on Amazon. Same product.

I will power two LED strip lights and a car stereo. No fridge, no A/C, no heater. What will I need more than 30 AH for? BTW, it is TWO 100-watt panels. I will mostly be camping alone. I have books. You know, those paper things with words on them? I want to listen to Live at Leeds and the Minor League baseball game (with the rule changes, I'm DONE with MLB). Maybe the Sunday Morning fishing report on KFBK.

I hate how people feel the need to swing it. ANYTHING that involves GEAR (guitars, cars, light airplanes, photography, fishing, hunting, boating, you name it) also seems to involve d***-swinging. I have done my energy audit. 30AH is plenty.

I really think they are lying to you about it being an MPPT type CC. Just my opinion based on others purchasing cheap CC's that were posted as MPPT but were not.

A typically and safe charge rate for Lead Acid batteries is about 1/10th the Ah rating. From what I understand you can go higher with LI chemistry but it really depends on what the BMS indicates what is a safe charge rate.

And a 12V 30Ah battery has a total yield of 360watt hours and with an Li battery you might get 80% of that for each use which comes to less then 300watt hours and can be easily consumed every night. Especially with a cheap inverter which may use 10% of its wattage rating or about 20 watts if it is only rated 200watts.

Just be careful on what your loads are
