Just a big thanks for that! Soon as i finished watching this video, I calibrated everything. Good explanation. Easy to follow and you showed the results. I apparently was doing it wrong for years. No one ever explained this part. I will add, that I had to turn off the solar panels, as it was causing the readings to constantly change. They made it almost impossible to calibrate properly. Once I did that, it was easy.

I realize it has been 6 years since you posted but I have an additional question relating to the inverter matching the battery voltage. We purchased a new to us DC Solar Trailer that has a Midnight Classic 250 CC and (2) SMA 6048 inverters. The CC needs to match the Inverters on voltage but they are not exact. I am still learning how to adjust the parameters/menu settings. Since it has a backup generator on the trailer I would like to limit the run time on the generator as much as possible going into winter months without having the IFLA cells suffer sulfating on cloudy days. We will have to purchase new panels - these are cracked and went through a hail storm. I am trying to find the best solar panels for maximum solar production balanced to the 510AH IFLA. Any thoughts in regard to how to keep the CC at maximum charging capacity without burning up the CC.
I have two 6 volt AGM batteries in series to make a 12-volt and my Outback is set to 13.1v and this is for a 12-volt system should it be set to this? Or 12.9?
I apologize if this observation is corrected later in the video, I stopped at the reference to an uncalibrated multimeter being used to calibrate a charge controller. I am a retired 65-year-old engineer. Never in my experience did a manufacturer of any high-quality device test (important for performance) their products on their production line(s) with uncalibrated equipment. A mid-level multimeter (DVOM) is not necessarily going to give you a more accurate reading than the product you are trying to calibrate with it. You need to have your multimeter Calibrated traceable to national standards (like no doubt the company that manufactured the Charge Controller has) and calibrated annually. If you purchase a Fluke brand multimeter you have the choice (most of the time) of paying a little extra and receiving it from them with Calibration data for your specific meter traceable to national standards. That meter you can use to calibrate with. Not an off the shelf mid-level meter.
I have one question. That calibration match the reading of the battery voltage on the inverter too? Cause the voltage drops a little when your inverter is working with loads. In the morning my inverter says that the voltage is 24.4 but the charge controller says 24.1. Wich one is correct?
That’s exactly why I’m worried. That’s what I did, but the charge controller will be judging the voltage when the inverter is working. How the charge controller will know? I will try using the voltage from the inverter. That voltage is the real voltage, cause it works with the shunt. So he is not accounting the voltage drop at the battery terminals. Or that’s what I’m trying to figuring out.
The Real voltage is right off the battery. When inverter pulls load voltage might drop a hair but that should show the same on the charge controller. But it also depends on the type of battery ur using. Lead will Sag like that. I'm using Lithium ion I don't have any problems.
Modern Off Grid DIY Can you make a video explaining better some parts of the advance menu, like Mpp range limit %voc and the park Mpp? Also what mode is better mpp auto or U-Pick. Thanks bro!
Hey there. Great video. Everybody keeps talking about your battery manufacturers specs. I have 4 - 6 volt magnacharge batteries gc225. 20hr/220. I cannot find any specs for these batteries. I have emailed the company many times to no avail. So I have no idea what to set the float , absorb ect settings.
It freaks me out seeing your solar panels on the ground like that. Are you at all worried about visitors driving on to them, or some other accident?Amazes me how much power you get from your system tho. Awesome!
Thanks for the support, I'm not worried about the panels I'm the only one here. So only me or the sheep could brake them but the sheep don't miss with them. Plus my solar panel mounting frame is being shipped. Not Much Longer on the ground. The system is doing crazy good. I have more panels I still need to install. I have so much power in the upcoming videos I'll explain more and show how it's setup.
Please tell me about how you have both hooked up. I am concerned about feeding both the solar and the wind to the batteries. Are both charge controllers just hooked up to the battery bank? I guess one pulls harder if the other isn't producing much. Till the voltage reaches the settings? Thanks.
How do you change the input volt value on flexmax 80? Without the panels connected it’s showing about 19 volts coming in when it should be zero. Thanks
I need to get a charge controller and have been looking at outback and midnite . If you only had one brand what would it be and why ? how long did you have these? thank you
You set the absorb end amps to tell the charge controller to stop charging the batteries when it hit it. basically the batteries take less amps as the batteries get full. Every battery has its own end amps.
Hi and thanks for the info, my EPEVER charge controller wont let me calibrate it in any way, on a 12 volt system it shows a huge difference, the charge controller display shows the battery's are at 14. 6 (maxed out) but my shunt and multimeter shows they are actually at 13.8, my batteries are suffering for it, ridiculous.
I completely understand where your coming from. Outback and midnite let's us change the values to match the batteries. Sorry to hear the brand charge controller you have wont to you change them. Sucks
@@ModernOffGridDIY Thank you very much friend for answering me so quickly, I appreciate it because I want to do the same thing by connecting my battery bank to a wind generator and five 345 watt solar panels.
Hi! Edwin Berrios, from the Island of Puerto Rico. 🇵🇷🇺🇸. What I like to know is If need another Batterie bank to Run the Wind Turbine.? Can I run the Wind Turbine with the Outback 60amp, and another for Solar to the same Battery bank? Thanks Best Regards Edwin Berrios.
You don't need to battery banks. Wind Turbine can not be hooked up to outback charge controller only solar. I use midnite solar charge controller for wind turbine.
@@ModernOffGridDIY yes it say battery charged.but when i put under a load it will not go into float.i let it pull down to 47v and still does not start charging again.Unless i did wate long enough for to start charging on it own.I have 16 trojan 6v battery
With all do respect, and really I don't mean to insult you in any way, I've been watching you since you first started with those 12v systems, and you've advance to a really realiable system that you should be really proud of. But you should really clean up the clutter at your site, and clean up the installation so that it looks more professional. Your Information over the years and your gain experience have been invaluable to many who follow you myself included I'm a 35 years in the trade electrician and like many of the ideas you've done.

Thanks buddy
I have two 6 volt AGM batteries in series to make a 12-volt and my Outback is set to 13.1v and this is for a 12-volt system should it be set to this? Or 12.9?
Why did you set the Flexmax's absorb time to only 3 hours when you have more peak hours of sunlight hitting your panels?
Absorb was set even less time none. Be lithium ion batteries dont need that only lead batteries.

What are your set points for them batts. float - bulk volts
Hi, to calibrate a battery with a meter, the solar equipment have to be in rest or you can do it with a hard son??
Do you have a Outback? My 12-volt system is saying 13 volts going out should it be at that level? Or 12.9?

What setting can be done when this controller is not reading output from the solar.

That's a hard question and Great question. I might have to make a short vid on that it's a really up and up race. Both have good and bad too.
For CTL70- 12V battery what is the battery charging voltage to set it up on the classic charge control. ?
Do you have a Outback? What should the reading be for a 12-volt system going out? Mine says 13 V going out to my 12-volt system? Is this okay?
What about absorbw AMP end setting?
What about it what's the question?

Yes

Yes no problem.
Can I use the midnite for wind and solar at the same time? Or I need two Charge controllers?
No.
Can I used a outback fm80 for my wind
No

@@ModernOffGridDIY so has to be a midnight classic
For outback 60, is 60amps and 150vdc is the max pv output?
You have it backwards. 150v max input at 60 amp
Como puedo verificar el Bolt que BA a llegar al regulador de los pv ?
And what is the volts on a dead batt
I read battery can still show voltage. It's about the cells

Use a good voltmeter > Such as Fluke etc. and verify your meter is calibrated.
cant belive these are not calibrated in the factory!!!
I agree it should be scary if you don't know
How would the factory know what your system specs are?
after my flexmax 80 comes out of absorb charge it stop charging
It should say charged. Batteries type ?
@@ModernOffGridDIY yes it say battery charged.but when i put under a load it will not go into float.i let it pull down to 47v and still does not start charging again.Unless i did wate long enough for to start charging on it own.I have 16 trojan 6v battery
