DIYS EMERGENCY SOLAR + BATTERY BACKUP FOR REPTILES

Postby kingofnobbys » Thu Jan 30, 2020 5:04 am

Scenario :
Power lost for a while, petrol ( um gas ) not available ( might be rationed ) so a generator is not an option , but there is some light during the days .

So what to do to keep the basking globe / MVB running ?

Answer a deep discharge 200 AH battery , this will keep you going for a while , but will eventually drain and you are back to square one , no generator available or no gas to run it ( remember ).

Power = IV = current x voltage.

Interesting site here to help size the solar kit needed : https://www.redarc.com.au/calculator/solar , even does the P calc for you .

Result I got with a 200 AH back up battery , most everyone should have one of these in the RV ( as part of the dual battery system ( starter battery that power car ignition (typically 75 - 100 AH) + second battery ( maybe 200 AH deep discharge ) that powers those away from home luxuries ( 12V lights, fridge, TV, and DC to AC converters for the laptop etc ) or camper or camping kit these days .
You'll only get 1.6 hr from a 200 AH battery powering a 120W globe.

For the 200 AH battery to power a 120W basking globe for 12 h/day ,

Wont be cheap but can be set up permanently to never need to worry about the backup battery ever being flat when you need it ,so long as you can get 6 hours of unshaded sunlight per day when there is no AC (mains power).
Recommended kit to add to the 200AH battery to take a 120W basking globe off the grid and keep it running indefinitely 12 hr per day :

Total $1742 to set up.

You mean I can't just vent my wood stove exhaust through the enclosure to keep him warm? :laughhard:
(Kidding, of course)

Thanks for the 411 (I believe it's 1223 down there?) :wink:
Not sure the solar option would work here without storage; this area has the 2nd lowest # of sunny days in the country, and they're almost all during the wrong season...

However we did make it through an infamous ice storm a few decades back, and several multi-day outages. Generators & gas (um petrol) are generally plentiful (when there isn't a disaster).

Planning ahead is prudent, though. Thx again.

Got no idea what that is. Guessing it's an American thing.

Only did this because I've got a 4x4 that spends a lot time idly stored in my carport and I'm fed up with having to get it started by the NRMA roadside assistance 3 or 4 times a year because the battery goes flat .

Hence since there is not mains power in the garage ( and it'll cost thousands to have it installed ) I'll soon be installing a solar maintenance charging system ( 120W or 160W folding portable solar panel + charge controller ) semipermanently in the car ( which happens to have it's tail facing west and gets direct sun light most of the afternoon most days ) .
Hoping this will remedy the problem and ensure my starter battery stays charged even if it's weeks between startups.
Not as expensive as the system above. Should get change from $1000 installed.

Yup. 411. It's the local number most folks here call for "information" (directory assistance) so it's become synonymous.
I tried to provide the Australian equivalent, but I may have gotten it wrong. :oops:

Ah … I see , long time since I used directory assistance . Not sure what the number is for that these days , too easy to simply look up white or yellow pages online .

Gotta love 4 countries (AU, CA, UK, US) divided by a common language. :wink:

My portable folding 160W monocrystalline solar panel , and 20A solar battery charge controller and remote monitor arrive on Friday.

Plan is to connect the 5m long Andersen connection 50A cable to the Pajero's starter battery permanently and run the cable along the cable tray from the engineer bay into the passenger areas and to the cargo bay , there the panel will set up temporarily inside the car facing the cargo bay door's window ( which faces west more of less and gets sun through it from about 1pm til sun set.

I'm hoping that even though the panel will only be partly illuminated by the sun ( up to 60% ) this should provide enough current each day to keep the starter battery fully charged.

My 160W folding portable monocrystalline solar panel arrived last night (big box !!!) and the rest ( cables , charge controller and remote monitor) arrived today.

Was a bit worried the solar panel might be too big when saw the box so double checked my Pajero's cargo bay dimensions

Image
Think it'll fit OK .

I think i'll get about 60% illumination on average most afternoons through the tailgate window , which means the 160W becomes more like 100W.
Since the supplier recommended between a 60W and an 80W panel if mounted permanently in the roofracks and exposed all day , 100W will be sufficient for maintenance charging of the Pajero's starter battery when I'll simply stand the panel up near the car or the cabin or the tent or camper ( if I get one before then ) .

And when we do the next long touring / camping / fishing greynomad holiday , 160W is pretty handy for keeping the Engal car fridge freezer and laptop going and charging a 200Ah deep discharge storage battery during the day.
