MPP Solar vs separate components

@beckkl if you have any questions on the procedure just holler also please let us know how it turns out.
Pictures would be awesome.
Good luck.
 
Any thoughts on how loud the MPP units are? If there is loud fan running all the time, it is sort of a deal breaker. I have no real way of isolating that sound.

Specifically the 1012LV-MS
Mine is not as loud as I expected, and it’s on the wall in the main living space. It does switch on when charging and when under heavy loads. I work for an IT company and am on the phone often and it doesn’t bother me.
 
Does anyone know the fan size(s) of the 1012LV-MS? I'm thinking about buying one for a solar generator / UPS0 project, but the fan noise will drive me crazy. I'm thinking I'd upsize them to 120-140mm with adapters if possible and put 200mm fans on the generator case itself. Plenty of airflow without the noise.

I've basically settled on the MPP Solar because I can't find an AC automatic transfer switch that switches faster than 80ms that isn't hundreds of $$ and inverter/chargers with builtin ATS tend to be $400+.
 
The nice solution here is an inverter/charger.
inverter/chargers are actually inverter/charger/transfer_siwtches.
the mpp is all of that plus a mppt solar charge controller.
I just did a big write up on how to integrate it.
Would be happy to help.
And about the fan noise, if it is a 12v unit they’re very quiet, the 24v unit can get noisy when it’s charging at 60+ amps or the inverter is doing over 2000 watts otherwise it’s quiet.
 
I've noticed my fan only really runs loud when charging the battery via shore power. Its also in an enclosed storage area, so fan noise hasn't been a big issue.
 
One thing I can say with this unit, is that the 1000W inverter is limiting. I pulled the microwave and A/C out, but I should have also pulled the electric water heater. It was a complete miss on my part. The real pain is that you are limited to 1000W REGARDLESS of if you are running off battery or shore power. My wife was not happy when she realized she couldn't run her little nespresso machine, even when plugged into a pedestal at the campground. I ended up putting in a separate outlet that runs directly off shore power. But it kind of stinks that I have to run an extension cord from the opposite side of the camper.
 
Good point. I have an AIO and it is very compact - mounted on the folding dolly along with LiFePO4 battery. It runs very quite.
 
these things look pretty cool. one question - how do you power DC stuff? I don't see any DC outs on any of the photos I've been able to find...

Right off the battery. Either to the RV fuse box or some other distribution block.

No worries ?

So you just run directly from the battery to a fuse box and set it up like any of the other systems patterned here?
 
Anyone who has an 812 or 1012 please report back what the fan sizes are. Thanks!

What is it mounted on? Something non-flammable?

I haven't received my 1012 yet but I'm thinking of mounting it on the end cap of this shelving unit, with something non-flammable if possible.
 
Yes, very nice. I may do that one also. But what is the MPP mounted to? Directly to the hand truck?

I am sure the MPP is mounted to the hand truck since he said it's portable. Have you watched Will's video. He basically did the same thing.

Will's is mounted to a board that is mounted to the hand truck. The question was what @Opusdei's is mounted to? Board or something non-flammable.
