Unfortunately not as good as an inverter generator in my opinion... apples to oranges for some...

So I noticed something new this morning. The battery was charging away in the morning sun, and voltage read 15v. There is a setting for the controller called "max regulation voltage" - so now I've changed my strategy a bit. I set absorb to 14.4 and max regulation voltage to 14.6 from 15. Now...

I got some new info from Morningstar. Their support is amazing. They said the timer for 'tine before float' is essentially time that it will hold absorb. I set it to 4 hours now. Especially with it being winter soon. They gave me a great rundown of what all the settings and values are with the...

Since my battery is always under use with the 12v fridge attached (at least, it is cycling a few times per hour), I went with these higher values. I hope it works out.

It is inefficient to go from 12v to 110v, so the actual amount of usage the fan will incur will be more than 45w. That being said, if it works for you and you have the battery power for it --- Personally, I bought a manual vent for the roof of my van for about 40 dollars, and a 200mm pc case...

Just got the modbus / meterbus adapter in. I set the absorb on the duo from 14.1 to 14.6. I set the Float from 13.7 to 13.8. I read that the "time to float" is how long it keeps it in absorb until it changes to float. Right now I have it set at 60 mins, but it looks like my controller was...

I probably didn't describe it accurately, but yes it holds the voltage until the battery eats less amps. On the rc charger there is no float though.  We'll see how well the 20a one does once it arrives.

I hesitated to post it because, although I don't mind tossing a few bucks on an experiment, I'd feel bad if someone else tried it and had a big problem... https://m.banggood.com/Intelligent-12V-20A-Automobile-Battery-Lead-Acid-Battery-Charger-p-1213520.html As far as the 2v cells... That's how...

DC to DC for a laptop is always better.

Sort of related... Ive just purchased a Chinese 20a smart charger for under 20 dollars. I had great success with one I bought that output 6 amps, so I'm hoping this doesn't end my success streak. I will have it in about 2 weeks. My current method was to use a smart lipo/lead/NIMH charger that I...

Wow this thread really got me thinking... I have enough room on the top of my van to replace my 100w panels with a couple of 300w panels...hrm...

I believe it - however, it also has a lower kwh per year rate, and is a lot less expensive. I think it depends on the needs, this cheap fridge works great for me :) If I was living in the van or an RV, I'd probably get something more substantial.

I'll probably leave it alone then. Batteries are ocean 100ah agm. 2 in parallel.

Attached is the configuration screen defaults. I plan to set it to 14.6, and 13.8 for absorb and float respectively. I guess I should leave the 60 min value alone?

Thanks for the help! I asked morningstar and they said it is their policy not to tell customers what to set the custom setpoints to. While I can appreciate that to a degree,  I was also a bit lost, because I provided the battery specs, and want to make sure I set their controller up properly...
