Most people don't get who Rosie is in the Jackson Browne song.

Yes, this is going on in select areas in Mexico. Very sad to see and financially feel in the pocket. I think covid has had a terrible impact on the economy down here just as in the USA and worldwide. I went to Cabo San Lucas about 12 years ago. I had a mental picture of what it was going to be...

Ahhh.... The Eyecrometer.

A number of years ago I found a Trace SW4024 inverter in a factory sealed box. This became my home inverter. It was 15 years old when I opened the factory sealed box and mounted it on the wall. I have a feeling this inverter will outlive me , not kidding.. As for maintenance, I have been using...

The digital thermostat is a no brainer. Easy to program. No complaints whatsoever. The cooling units come in single, double, triple and quad fan sizes. They are power hogs but i have used a dedicated 12 volt PV setup to power it. In humid conditions they will want to get frosty and you need to...

I sold some panels to a guy who was building solar powered pontoon boats. They ran directly off solar panels, no battery powering the motors. He had a pair of panels for one motor and another pair for the other motor. He would steer by cutting power to one motor or the other, depending which way...

What would be the minimum MPPT startup voltage of the 48 volt AIO? What is the Vmp. of the 300 watt panels? You need to make sure you can exceed the minimum voltage with flat hot panels. Might be difficult. Do you have room fora 3rd panel? in your case you might be better with a 12 volt system...

If you can fabricate an air dam on the front edge of the front panel to divert the oncoming air over the panel you alleviate the lift which is so dangerous.

With bamboo being the fastest growing plant on earth, supposedly, you might think about adding a second story on that shed, then, adding panels.

I think your plan will work just fine. Your controller will scale up to 48 volts and work with your 2s2p pole mount plan until the time you upgrade You might want to hang onto some or all of those Siemens 75 watt panels. They are really well made and come in real handy if you need to add a 12...

Love it down here. I'm 25 miles south of San Felipe. I live in the water May through Oct. Water was 94 a couple days ago. Ought to be good into November.

Looks like some bits of steel from sawing off some bolts or steel racking parts.

I knew I was going to be buying a house so I started the residency process and now have permanant resident status. That green card really makes things easier in many situations.

Not real familiar with the East coast. It's all "back east" to us Left Coasters. :cool:

Well, powered up the MS 4024 and all I can tell is the fan is a little noisy and the aluminum inverter housing is resonating and amplifying the minor fan noise. Light pressure (a finger) on the housing stops the noise. I think a well placed piece of 3M double-sided foam tape will take care of it.

Water will puddle on flat panels. As they get wet, dry, get wet, dry, etc. you are going to get a hard crust of mineral deposits on the glass which is hard to remove, especially on textured PV panel glass with anti reflective coatings. Go with the pitch. 15 degrees isn't very high so wont be...

Is this what he told you? Seems like the proverbial 10 lbs. of shit in a 5 lb. box. I couldn't imaging getting 3 12 gauge stranded wires crimped into one of the MC-4's contacts.

It really sounds like your battery is toast. When lead acid batteries are on their way out they will appear to charge really fast but will drain just as fast. They have no capacity left.

Well I feel for you. I bloated 8, 280 ah cells while top balancing them. I hadn't even got to use them when 1,400 dollars worth of lifepo4 sat there like fat little blue loaves of bread. Hope you can track down the cause. These cells are extremely sensitive to overcharging and they bloat up...

Not recommended to keep LFP at 100% as a standby battery. That's the reason they are stored and shipped at _+/- 40%.

With just two batteries all you need to do is put them both in parallel and run the positive charging/load cables onto one battery and the negative charging/load cables onto the opposite, diagonal corner of the other battery. Equal cable length isn't critical in this scenario.

There's always the Midnite forum. Lot's of Midnite specific info there. Plus the Midnite guys are active on it as well

But, did you stay in a Holiday Inn last night??

English translation. I just found this amazing item on AliExpress. Check it out now! €4.29 48% Off | Turmera 3240 Insulation Epoxy Sheet 0.5Mm Thickness 203*172Mm For 3.2V 280ah 320ah 310ah 90ah 12.8V Lifepo4 Battery DIY Usage

No but, all you need to do is get a single panel and a DMM (meter) and set it for current and, while tilting the panel toward and away from the sun, you will see a big difference in current. On the voltage setting you will see full voltage in poor light and not much more in full sun.

Panel voltage isn't what you should be concerned with in regards to better charging. You will get near max Voc/Vmp in most lighting conditions. The current is what you need to focus on. If your panels are mounted flat on the roof of your RV you really are struggling to get much current at this...

That makes sense in a grid tied scenario. For the life of me I can't figure why one of the installers around here is orienting full off grid arrays to the west down here in Baja Calif. Would you not want your battery bank charged up as soon as possible after taking it down overnight?

I'm not sure I'd give that even an R Rating.

Color has nothing to do with it. I am referring to the design of the blue one.
