What is your battery capacity in the RV?

Where is the "van build" section? Thx. Fred

I'm looking at a fridge that draws 700 watts per day which converts into 30 watts per hour. I have a 1500w inverter but am wondering if I could use a dedicated 100 w cheap inverter to reduce the parasitic draw of the inverter? How can I determine the parasitic draw of the inverter? Thanks Fred

I would use the hole saw size you need and drill the hole from the inside. If you hit a structure piece it is easy to put a patch on it. At least easier than from the outside. Your getting pretty close to the window frame so there is a good chance there is a structural piece there.

Are AGM's better/longer lasting that fla's.They are certainly more expensive. Regards Fred

You have 500 Ah to work with and the 400watts of solar is plenty to recharge them. You can also calculate the power usage of the fridge, TV (we use a low and dvd player. In my experience the water pump uses little power because it is used so intermitantly.. The max air vents are VERY low users...

Is it possible to run more than one gauge (where each requires a shunt)off a single shunt providing they each require the same size shunt? Regards Fred

:):):)

I have 3x 100w solar panels feeding 2x12V FLA's. Can I safely add an 12vAGM to this? Thx

Thanks Fred

On my bus I have an AC outlet off the inverter. When on shore power I plug the shore power cord into the capmground AC supply but when running off the battereis and inverter I plug the shore power cord into the AC outlet connected to the inverter. Not automatic but simple.(Kiss principle.)

Just out of curiosity but does the AIli gauge(with shunt) perform the same functions as a Trimetric. Big difference in price.

Trusses 12’apart???My pole barn has trusses2’ apart.

I have a barn that has metal over shingles on purlins and don't think you want to just fasten the rails to the metal.

What is the difference between Lifep04 and Lithium ion. Are they similar in number of cycles, cold charging etc.

What is the difference between short and open circuit voltage?

I am contemplating replacing my propane fridge in my motorhome with an electric one and want to make sure my math for power usage is correct. Using a hypotherticas fridge that is rated at 297 KWH/year(365 days) would this work out to 6.78 Ah per 24 hour period? Im not taking into account any of...

"No fridge draws 700w per day. It does not work that way. Its draw is dependant on a half dozen factors that change average compressor run time drastically. Actually, according to this guy it does. (http://www.beginningfromthismorning.com/securing-the-refrigerator/) Its rated at 1kwh per day...

"Wait.... how did you figure out 500ah? I forget what the equation is. There are a few to remember" My bad.Should be 250AH, I think I used 8 gauge from the junction box on the roof to the controller. Check with a voltage drop listing to see what gauge to use so you don't get voltage drop. Also...

If you haven't already done so go to Smokstak.They have a separate forum for Onans. I have a older Onan and go there for advice and parts. Also go to this guys site.(http://www.beginningfromthismorning.com/) He is converting a bus for full time living.He has dozens of very informative videos...

Still comes out to 31800.

What would be the practical use for a unit like this .When I think of a power failure what comes to mind is my refirgerator , the freezer and our well water pump. I seems to me that just he fridge alone would use up most of the battery power in just a few hours. If its for charging my cell...

The existing FLA's are not sealed.

Thanks. Good to know.

I live near Vancouver Canada and am being bombarded with companies wanting me to install solar. The interesting part is that the Canadian Govt will provide a $40,000 interest free 10 year loan to do it. I have no idea of what it might cost although I do understand solar as I personally...

On my motorhome I have 3X100w panels feeding into a Renogy PWM controller. I think it is rated for 50VDC so I can add another panel. What is the advantage of using a Mppt controller vs the pwm if I don't have any plans to have more that 400w. Regards Fred.

What is the downside of not balancing the cells?

I read where these batteries are "drop" in but also reading that external software is used to install/balance/maintain them. I'm considering buying 2 of the 138AH ones to replace the 2 exisiting FLA's. Am I correct in asuming that I can simply unbolt the fla's without having to balance, test...

So you get snow.It doesn't snow every day (just like its not cloudy every day) And when it snows brush it off. (which you can't do with clouds) and the sun may be low in the sky in Manitoba but there generally is lots of it.

It looks to me like you have a breaker panel/converter setup.Shore power goes in and dc 12 volts goes to the fuse panel and 110 to the a/c. I can't tell if you have battery charging from the converter. I have a similar setup in the bus I converter but it also does battery charging(or its...
