MPPT Controller Explanation For Dummies

[endoftheroad]

UPDATE,
It's been 7 months and my 2-Kyocera 140 watt panels, 4 Trojan T105's and 2 Genasun MPPT controllers are registering full everyday and not dropping below 97% "State of Charge" according to my regularly synchronized Victron battery monitor.
Refrigeration, computers, lights, movies, anchor lights and much more for my wife, my dog and myself.
I topped off my batteries a couple days ago just for something to do, didn't hardly seem necessary.

Very satisfied.

How much does the dog use daily.

[endoftheroad]

Oh...I guess he uses his share of refrigeration space for his kibble.

Should keep the naysayers pretty well shut up

Not really. Not going below 97% capacity tells me he has something set up wrong. Its impossible.

Yep,

It looks good from my house. Words not to live by.

Refer alone will take a bank lower then 70% on average overnight.

Unless it's a huge bat bank.

Which according to the OP it is not.

A cynic might find it interesting that anyone thinks dog kibble is ever refrigerated. ;-)

Why should a well done fridge take the batteries down to 70% over night. Mine only uses around 30 amp hours in a 24 hour period. The lowest I have seen my batteries early the next morning is around 85%.

My waeco danfoss remote compressor comes on about every hour and 15 minutes and it runs for about 15 minutes (last time I paid attention).
There's nothing wrong with my set up.
Duplicate my system, you'll b happy..

And live in the Florida sun.

To get a true idea of how much any appliance uses over a 24hr period the appliance should have the measuring equipment in it's supply line. simply looking at a SOC% meter will tell you how much was drawn from the battery while the charging system was not operating, many will reduce the total of used Ah till it reches zero, then start to record Ah in, this leads to very inaccurate assumptions of the actual power requirement of an appliance over a 24 hr period.

Product update;
It's been almost a year and a half and I've had zero problems with my system.
It provides me with much more power than I know what to do with and silently I must add.
A couple weeks ago my Victron battery monitor got stuck at SOC 100% and wouldn't display any consumed amp hours.
I called Victron, a fellow named Rich assisted me, I was in front of the monitor so he walked me through it. I was only calling him for help regarding a "hard resetting" procedure that was above and beyond the syncing/resetting that you do periodically when the battery is full. Rich determined something may be faulty and sent me a new unit. I received the unit yesterday and before I replaced the display I unplugged the current display and plugged it back in and "walla" problem solved. I'm bot sure why I overlooked unplug/plugging of the unit but so did the technician.
Anyway, Victron backed up their product simply by a phone call with no proof of any sorts, not even a receipt or a customer account of myself in a computer.
Now that's what I call some serious customer service!!!!!

Very happy customer and thank you Rich.

Now for an ice cold drink from my refrigerated ice box.

Great to hear a good news story regarding a supplier, they seem to be getting few and far between lately. I've found the Victron BMV to be an excellent piece if equipment and great value for money. I haven't had one muck up on me yet, but I'll keep the shut down reboot in mind if we ever do have a problem one. It's good to hear that the customer service people are easy to get along with as well, that always puts a gold star beside their name in my book.
