RE: 1/2 KW of solar, 1,450AH of batteries - Ultimate dry camping

Hi b, Yes, solar may be addictive--or the circumstances may change. When I was using my rv a week or two at a time I had enough solar. Now that I full time--I would prefer to have 1300 watts available. The good thing is that 1300 watts now may cost less than 256 watts did last time I got on the solar wagon.

RE: Best/Fastest route to Edmonton from Florida

Hi, Minot, Regina, Saskatoon, Edmonton. Highway is twinned from Regina on, which means a faster speed limit. It is also shorter.

RE: best price for agm batteries in Canada.

Hi Mex, If I go south I can get them for $1300. If I buy the same capacity in Canada it will be $2700.

best price for agm batteries in Canada.

Hi, Has anyone got a good source for low cost agm batteries in Canada?

RE: 1/2 KW of solar, 1,450AH of batteries - Ultimate dry camping

Hi B, Cupping is not an issue with Unisolar. It is with some other companies. It is true that Unsolar requires a huge area of roof space, but it is also true that their low light performance is better than most other panels. I may end up starting over because I now want a lot more watts to be available per square foot of panel.

RE: Question For AGM Battery Owners...

Hi, Best Converter sells them for $199.00 Amazon $185.00 So my rv dealer has Fullriver dc224 batteries on sale for $250/ea. I was thinking of picking up 4 of them, but not sure if my charger and inverter are up to the task. i have an Iota charger and a Xantrex 1000w inverter. Will the Iota charge an AGM battery properly? The little I found on their website really doesn't tell me.

RE: Over night in Salmon Arm

Hi, There is a Walmart in Salmon Arm. I received permission to stay the night.

RE: Charging Issue

Hi, My RV loved to blow the 60 amp fuse on the "house" battery charging circuit. I replaced it with a 50 amp self resetting breaker. The OEM solenoid lasted less than one year. I replaced it with something that is better rated.

RE: Question For AGM Battery Owners...

Hi, I've seen 125 amps from the Magnum 3000 hybrid. That's all the energy from a 15 amp shore power, so when the fridge cuts in the charging scales back. I've also seen 125 amps when running the Magnum from the Yamaha 3000 sIEB. It is interesting to hear the Yamaha "load up" as the Magnum ramps up to the 125 amp level.

RE: Question For AGM Battery Owners...

Hi BFL13, For agm an amp-hour counter becomes essential because there is no way to check specific gravity. BTW you shocked me by talking about that evil metrology call "watts". Next thing you know you will be advocating permanent flat solar panel installs. (is there an AA group for that?) I'm seriously considering a trip to USA to get lower cost AGM jars. The prices in Canada are insanely high every where I have looked. AGM's are not quite as easily sulfated, but once they are undoing it is a real tight wire balancing act. Everyone talks about no maintenance, but does not define what sort of maintenance that is. Obviously, you do not need an hydrometer or to add water. The thing seemingly ignored is equalizing-overcharging-topcharging after doing a camping session off-grid of several 50-90s in a row. The AGMs need it, same as Wets would, but how in heck do you measure your progress in doing that without an hydrometer is the mystery. So people who respond to this thread should be careful to explain their own scenarios wrt that.

RE: CrockPot Cooking

Hi, Since I'm in a class C I even crock pot while trundling down the road. I simply put the pot in the sink.

RE: Leveling class C

Hi, I leveled the fridge and then added stick on bubble levels in the cab so I can see what is going on. Shortly I'll have my ARP fridge protection unit installed--that will make leveling less critical. For the actual leveling I'm now using Andersen levelers. They work well.

RE: Surge Protector - Progressive, or something better?

According to Dometic, amp rating on a 13500 btu unit is 13.4 amps. Locked rotor amps are 63. They don't list the name plate voltage. The do want #12 wire for runs under 24 feet. More than that and they suggest checking the national electric code. Dometic air conditioner If we assume 115 volts then wattage is 1541. I know I've seen as low slightly under 1200 and as high as 1900. At 1900 and 106 volts that's over 17 amps flowing through the motor. I can't imagine this is good for it, as a 10% tolerance would be about 14.75 amps.

RE: Battery size question

Hi, The wfco is known to have a problem going to boost mode. This is what is balanced and best for twin twelve volt batteries. Unless you wire this way the battery bank combined with a rather poor converter will lead to early failure. My 12 volt jars are over nine years old and starting to show their age. http://www.rubyorchid.com/RV/images/Pianotuna12V.png As it often doesn't cost a dime more to do this, I think it is worth the trouble. If you wish to understand the "why" surf here: correctly interconnecting multiple twelve volt batteries Others may say it doesn't matter--but unless there is a compelling reason to not optimize charging and discharging why not do it the best possible way? Here is a video of 3 twelve volt batteries that have been wired in an unbalanced manner for 2 years. They have been equalized. The test shows how CCA has been adversely affected. unbalanced for 2 years

RE: 1/2 KW of solar, 1,450AH of batteries - Ultimate dry camping

Green, definitely I'm green with envy. If you wish to make them portable, they are sized to fit standard metal roofing panels.

RE: Surge Protector - Progressive, or something better?

Hi, Tolerance is often (but not always) 10% so 115 name plate suggests that 103.5 is the lower limit. With 120 volt that becomes 108 volts. I'll stick with 108 myself for the lower limit. I do know that last year at a campground on a hot sunny day I had to turn off everything except for the air conditioner. This summer if it is hot, I'll spend the money for a 50 amp site (if available). The air conditioner was drawing over 1900 watts. That is a sure indication that voltage was too low for my comfort zone. The thirty amp pedestal breaker blew twice with just the air conditioner running. I suspect old tired breakers and minimal wire size in the RV park. There is an autoformer in my future. OK But what is the lowest voltage for the motor? My Dometic says 115V period. So do I turn it off at 114V or at 107V or whatever? And your motor may be different and it may not be 108-132? Just raising what-ifs?

RE: Is this converter safe to install?

You need to run #8 or #6 to the battery bank from the converter. Or fuse at 30 amps, or automatic circuit breaker at 25 amps.

RE: Any really good reason to upgrade to AGM?

Hi, Always teasing us, eh? What brand are these AGM's? Thanks in advance. However, the recommended float voltage for our two AGM batteries - 13.5 volts to 13.8 volts - is a perfect match to our single stage converter's nominal output.

RE: Another Surge Protector Post

Hi, 103 is too low for the cut off. At that level damage is accumulating in the electric motor(s) of the air conditioner. Are you sure it is 2 minutes? I thought it was 3. 2 is not quite enough for the head pressure to bleed off. My own comfort zone is 108 volts. Get the PI EMS and enjoy your stay. It will cut off power to your RV for several different dangerous situations, wait 2 minutes, then reestablish power if it's safe.

RE: Any really good reason to upgrade to AGM?

Since you never boondock, you could use a flooded sealed battery.
