Yessir, I agree. But it is obvious that when I intentionally create a load / drain the batteries the charge controller jumps from 50 to 60 watts up to 580W or 700W. So since the RV is sitting there in partial sunshine, the charge controller has available PV watts and is providing what is...

Snoobler is essentially right. However, I have observed that the Victron MPPT reads just the amount of watts that it is putting into the batteries and not the amount of watts being produced by the solar array. I will occasionally turn off the battery charger and slide the RV slide outs in and...

I was pondering if it would be better to connect the leads from the Victron MPPT charge controller to the input terminals of the Multiplus Instead of directly to the batteries? The question would the charge controller prove more power from the solar panels when a draw is occurring on the inverter?

Oops in your case propane...

I live in town because I had to be on call 24/7 in my career before I retired. However, being an architecture major my house has natural gas heater, water heater, gas dryer, and I recommend a gas stove/oven. Also all of the light bulbs are LED. If you do these things you will greatly reduce your...

I just finished mounting 8 x 100 watt panels on the roof of my toyhauler. Although the system is working, I’m currently waiting on a Victron multiplus 12V/3000W/150A to arrive, in order to get back to work on the RV system.

Sorry again, I received your reply just after I hit “post replay “

Oops, I reviewed the Titan solar generator. Sounds like you should sell the 100 watt panels and buy all Renogy 160W’s

What if you used two charge controllers ? One for the 100watt panels and another for the 160 watt panels. ??

By the way, now that I purchased the Renogy aluminum mounts and the Teflon corner brackets. I was wrong, they cannot be used together. The different style mounts are each a different height off the roof deck. I did use short thickness electrical unistrut and unistrut mounts with 1/4” machine...

The 2 series brings the 100 watt 12 volt solar panels to 24 volts per pair. Consequently, VOLTS X AMPS = WATTS And wire size is determined by amps only. NOTE ; we are working on the solar panel side only. SO the formula notes that when you double the voltage, you cut the amperage in half. Thus...

HRTKD and Solar_Mann , l posted before I realized you had answered. Thank you

Jcain, l see you run Victron in a toyhauler...My current plan is to install a Victron Multiplus 12V / 3000W / 120-50 inverter charger. My RV has a 5K generator and 50 amp shore line. Factory installed is a 1000 W Magnum sine wave inverter with a Magnum 15A transfer switch. Also factory installed...

Well, I assume you are asking jbelleti. From his excellent photos, it appears he used stainless steel brackets screwed into the roof and covered with Dicor self leveling sealant. An absolutely beautiful system. It also seems that excellence was the primary goal and cost wasn’t. “Do it once...

All 6 batteries are parallel, thus 12 volts 600 amp hours. Consequently, I would need the solar panels to produce about 18 volts or more to the solar charge controller. So it seems the series X 2 for 24 volt panels would be the best avenue?

Dzi, back to your comments on wiring the solar panels. My choice is 2 x series 24V to 3 x parallel pairs because as you noted, my concern would shading of my roof. It may be better to go 6 x parallel panels. FROM THIS WEBSITE: Victron 60 amp controller “Max Solar Array: up to 860 watts at 12...

Well guys, I really appreciate all the ideas. Truth be known I have rebuilt 3 RVs and owned 4 besides those. I also work with 3 phase electrical systems quite often. I am new to solar systems. And I am learning from all your thoughts. Thank you and don’t stop. Snoopler, great idea with the 30...

I have another question. My plan so far is to wire two 12V 100W solar panels in series for approximately 24 volt. And then the 3 pairs in parallel to the Victron MPPT 150 /60 smart controller. From reading Will’s book and watching his videos, I assume this is the best way to go?? Thank you...

Thanks guys for the advice. Yes I have my system set up for 12 volts. Obviously everything in the RV is either 12V or 120V. I would absolutely love to use the Victron 12V / 3000W 50A Multiplus, but it is $2600.00 all by itself. You can see I have already purchased all Victron Bluetooth...

I have a toyhauler which has a 5kw generator and a Magnum 1000 watt pure sine wave inverter, factory installed, for the residential refrigerator. I have replaced the two original lead / acid batteries with 6 AGMs, 100 ampHrs each. I am installing a Victron 712 smart battery monitor, 6 HQST 100...

P.S. I have already installed 6 Interstate group 31 AGM batteries 100 Ah. Looking back I wish I had spent a little more and used Battle Born.

Wow, what a great looking system. I am currently building a RV system with 6 x 100 watt HQST mono crystalline solar panels. I was planning on wiring each two panels in series with Y connectors to get the voltage up to 24+ volts and then the three pairs through the roof to a Victron MPPT 150 /...

Oops, I don’t know what caused that.

Bob has some good advice there. Just an FYI; I have a much bigger battery bank and I suspect a much bigger camper. I did run several actual tests with the GP-200 watt portable. It can be set up to face the sun and the factory extension cord is thhn 12 awg with Anderson plugs. It consistently...

Well now, that’s an idea. Even if below grade isn’t practical. There are design principles, sunshine on the well house walls will create a lot radiant heat buildup. First shade the wall with a long roof overhang or soffit. Make the wall reflective ie... shiny tin, or white. Sherwin Williams...

MAYBE...that is a high end fan designed to cut through the Dust Bunnies that continually attack computers??

You are correct, the batteries mounted on the tongue solves the ventilation problem and the 6 volts do have thick plates. There are some excellent solar purposed 12volt batteries these days. However, costs / needs are important. Don’t forget 2 battery boxes and 2 additional heavy cables. FYI; I...

While I don't believe that is what your talking about. Since you mentioned gravity feed. It would take about 92.25 feet of elevation head to get your 40psi and more elevation (friction loss) with the valves open. ? Sounds likes good plan... Now how many watt hours do you need for how long...

I looked up Duracell GC2 and there is a wet acid version and also an AGM version ? It matters. Are your camper batteries mounted outside on the tongue or in a compartment? Wet acid batteries have to be vented properly. Also 6 volt batteries have a high amp hour rating. But as you know it...

WOW ?? I am a newbie here, but my research indicates that BattleBorn Lithium Iron Phosphate batteries 12volt 100 amp hour are the best. $949.00 from BattleBorn and the same from Amazon. Didn't check shipping $$ ? Yessir they are expensive, very long life and near 100% Ah available. Second, I...

I know this is a solar power site and Supervstech is a HVAC / Electrician. But since you need heaters 24/7, how far away is the chicken coop from residential electrical/grid ??

You mentioned your roof leaked at the roof penetrations: There is a Dicor lap sealant, self-leveling. Comes in an ordinary caulk tube and it is great stuff. I use it a lot, about $11./tube and worth it. I’ve used it on commercial metal roofs also.Be sure to throughly clean the surface...

Besides decades of construction and a degree in architecture there are two principles to keep in mind. Whether it is St. Patrick’s Cathedral or a deer camp. “You must keep the water out.’ Or it will eventually destroy your structure. Also, “A threefold cord is not easily broken.” When building...
