Add DC charger or power supply to 12v system

[Mike90250]

I don't play golf but would a golf cart buggy batteries be flood batteries? and omit gases and acid? your sealed Gel is way safer around kids. What your planning sounds like you only need a battery box with a larger AGM around 125AH and a smart charger just for backup in overcast weather. If it's a teaching thing why not learn how without mains at all. Cheers Phil

Well, if you have to be that safe around your kids, maybe a padded room is the thing. Flooded, Gel and AGM batteries all contain LEAD, ACID and dangerous amounts of stored power. Even the little batteries in toy ride on cars are full of lead and acid. And the tots sit on top of them !!
Students need to learn, and at some point, it has to go beyond book learning.

Today, at this moment, hundreds of thousands of bill payers have had their power cut off, in an abundance of caution, because they dared to complain last year, about poorly maintained power lines, being blown down and igniting huge firestorms.

Shop classes in our schools have been closed, too dangerous to work with "sharp tools".

And get to your dictionary, and figure out what omit means.

Have you seen some of those hover boards and vapor cigarettes exploded because the Li batteries got too hot. There isn't any type of "battery" that is not dangerous at some time.

I sometimes wonder if what some consider to be all the nanny type gov. mandates to keep humanity safe from itself is working to the detriment of degrading, or at least not improving, the gene pool. Stupid people can no longer kill themselves as easily, with the result that works to allow more stupid people in the gene pool to pass stupid genes to their stupid offspring. Entropy strikes again.

Another result: Redneck engineering is harder to get away with. That stifles innovation.

more stupid people in the gene pool to pass stupid genes to their stupid offspring.

Now that's some funny stuff there.

Tony, From what I gather your installation is just for educational purposes and you have a constant electrical supply from which you wish to charge your battery which is very quickly getting to the throw in the bin stage, because of excessive deep discharges and inapropriate charging.
I think that the best thing to do in the imediate is to seperate the demand so as to supply only the lights with the solar system and the rest with your 220 v supply.
Once you have established what can be run reasonable by the solar panels and battery without destroying any more equipement you will have an excellent set up for educational purposes. You will also have a perfectly functioning toilet.
The money that you will save by not damaging your battery or frying another charger will allow you to buy another battery sooner.

Flash fwd to today. 11-12-2018
Both the CAMP & WOOLSEY fires had electrical substation anomalies minutes before the fires. The power was not cut proactively.

Sounds like an issue to me. Either the POCO cuts the power early and put people in the dark or they hold their breath and hope a fire doesn't start.

Maybe a change in how the state takes care of wooded areas along the power lines needs to change or most of CA may go up in smoke.

The state takes care of squat, at least under rights of way. That's on the POCO's nickel.

SDG & E sent word to all customers about 24 hrs. before the latest Santa Ana event started stating - in a cryptic fashion - that service would be interrupted as a pre-emptive measure if the wind got bad. My guess is that such notification is partly or more of a cover-your-ass posturing/move.

Heaven forbid we ever get hit with a giant CME from the sun. Any POCO that doesn't shut down before it hits will have hundreds of transformers to replace.

Maybe having a battery backup is not a bad idea for some places.

Sad to see and hear about CA fires, all preventable with proper forestry management.

FWIW:
~ 3 % or so, maybe a bit less of the forested land in CA is controlled by the state.

~ 50+ % or so is under federal control.

Most or all of the rest is privately owned/controlled, a lot of that by paper companies.

Part of the situation here is that there may be more forest than management, with the management piecemeal to some degree. I'd also suggest if half the forested land is gov. controlled, that's the worse half of the management.

Yep. And it looks like the Camp fire started in a Federally controlled forest as well.

I do not think it matters how a fire starts. It should be assumed that it will start in unfavorable
conditions, and ways to deal with it planned out. Here we finally just got rid of all the houses that
were always getting flooded, a tiny problem compared to California. Bruce Roe

It is hard to imagine that anyone would want to build a house that has been removed by water, wind and storm surge. Yet most of those people that have lost also have no where else to go and couldn't sell their land if they wanted to. So they rebuild and pray they will not be affected again in their lifetime.

As for having a house in a fire zone... I would do everything possible to protect it but that may not be cost justified unless I want to live in a Cave.

I guess you have to ask those that have a home in tornado alley or anywhere a hurricane has created a disaster. Why are you staying here? I think you will get many answers.

Well having lived in Tornado Alley most of my life in Oklahoma and Texas there is one thing we know about tornadoes, they are a lot like lightning and does not strike twice. Unlike Hurricanes and Wildfires that strike the same places frequently. Do not know if that answers your question or not, but if you are in Tornado Alley your chances of being hit by a Tornado are about the same as lightning, well maybe a little higher, but twice is highly unlikely. However if you live on the east or gulf coast it is a matter of time before a Hurricane passes through and visits.On the west coast especially CA region you will likely be in an earthquake, wildfire, or mudslide. You cannot prevent an earthquake, but there is some control you have over wildfires and mudslides, it is just not done. Comes down to this. If you live near a coast is a known risk and decision you made to live with. Heck I live next to a volcano, and if it shows sign of activity, hello TEXAS.
