Thinking to go Solar

I am a full timer and live in my 5'er and live in Fruita Colorado. Now Colorado has more sunny days than any other state in the union. I think of going Solar. I have a 341 RLQS 38 footer. I have alot of room on top of my 5'er. I can have approx. 4 to 6 panels on top. And yes I know it's going to be expensive. I have been looking at batteries like the Rolls and Trojan 6 volt deep cell batteries.

Now I run approx 500 to 600 KWH per month that I am hooked to the 50 amp pole.

I am thinking to put 2 of the batteries in my generator box thats in front of the 5'er. These are not cheap and weigh about 318lbs each.

Here are the specs:

Are these batteries goin to be too heavy for the front of my RV?

I don't know anything of the Rolls batteries. I went with Lifeline 6V Gell. 4 batteries make 600 Ah at 12 Volts. No water or venting gasses to worry about. They aren't cheap. I'm happy with them.

They say about one Watt Solar for every Amp Hour. Then there's the inverter.

I'm installing 600+ Watt Solar and a 2000+ Watt Inverter next year myself.

Let us know what you go with and how like it.

Don't expect to run your roof air off of Solar.. I doubt even that expensive battery pack will handle it.. Convert all the lights you commonly use to LED. Always remember that the inverter sucks 3 ah just being turned on. Going solar does require you to think about power usage more than when you are plugged in. I am never on a powered site anymore.. been boondocking exclusively for the last 6 years.

If you are currently using approximately 600 kW a month/30 days= 20kW a day,and you have (6) 250Watt panels (1.5 kW) * 5hrs of sun (4 would be a better # to use) = 7.5 kW, which I believe will leave you with a deficit around 13kW for each day. This is using the advertised wattage and is not a realistic output. That 1.5kW would probably only be realized for an hour or 2 max (based on the panel mounted flat on my roof). Now throw in a few clouds and cloudy/rainy days along with less sun light each day until December, and you need to be charging your batteries with a generator/TV. My 1500 watt inverter uses about .4 amps with no output, but each inverter is different (check mfr specifications prior to buying one). I think I said that correctly....

What do you use monthly without the AC/Microwave.

Without the AC and using the microwave a lot, you would have a GREAT system, but you still need to calculate all your other electrical usage for a daily basis (Tv usage, charging laptops, tablet, lights......)

Just my thoughts,
Don

Some inverters come with a remote on/ off panel so you can shut it down when not in use and save some power. Not only will you save on the inverter load, but the vampire load of the 110v devices on the branch ( tv, microwave, etc )

Is there some type of auto switching you can use that would auto switch to the pole when the batteries get down to a certain power level so the solar panels could recharge the batteries and vice versa.

After my last post I remembered these batteries.. and since you are spending BIG BUCKS on your system you might want to look at these.. they are not for the timid of wallet..
