RE: Multiple inverters?

Hi mlts22, Most of us do exactly as you suggest. I have a 300 watt MSW that I use for small loads (the laptop and a heating pad for the bed). It is not hard wired. Running it flat out draw about 30 amps, which to some would not be a low load. Then I have my 3k Magnum hybrid for when I want to use the high draw appliances. It is hard wired. I have a choice of powering the whole RV with it, or just one outlet in the kitchen area. I have seen it draw 276 amps. Some day, if the MSW 300 watt fails I'll find a 300 watt PSW to replace it. I do carry a 1000 watt PSW as a back up for the Magnum. So far it has not been used.

RE: Adding Inverter for dry camping

Here is a simple flow chart. Budget-->Energy Audit-->Battery bank size-->number of watts-->PWM or MPPT. What ever type of controller is chosen, make sure it has adjustable set points and a temperature probe that is on the battery. One rule of thumb is between 60 and 150 watts of panels per 100 amp-hours of storage. The smaller the battery bank the higher the wattage needed (per 100 amp-hours). Here is a link to the rather special spreadsheet which includes an energy audit, that N8GS has created to help size solar battery charging systems!

RE: Air conditioning on solar

Hi Phil, Since we don't control clouds, poly is a better bet than mono. If conditions are *perfect*, mono wins but not by much. If they are not, poly outshines mono.

RE: Cell Phone Service along Alaska Highway

I must admit, I was quite uncomfortable to have no cell phone service from the Saskatchewan border to Churchill, Manitoba last summer. I had just turned in my last non gsm phone and Manitoba Bell was a late adopter of GSM. There was also well over 100 miles with no fuel between Hudson's Bay, SK and The Pas, MB. It is amazing to me how dependent I've become on the secure feeling I have with having the ability to call for help, if need be. In 15 years I've only had to call 3 times--but I felt very stressed.

RE: First RV for full timing: Used or New?

Hi, Welcome to the forums. Living in an RV may be more expensive than an apartment. Do not even consider a new RV. The makers seem to be in a race to get to the bottom of the barrel as far as quality goes. Almost all new RV's require repairs. If possible, dip your toes in the water by renting an RV for at least a month. You may find it is not your cup of tea. Where I live, renting a spot on a monthly basis costs $800. In winter time there is no other facility open. If you do decide to buy an RV there are three things to look for. 1. look for any water damage 2. look harder for any water leaks 3. examine every possible location for water intrusion.

RE: Electric Fireplace or AC/Heat pump

I've replaced all but 3 outlets in my RV with good quality screw terminal type. As I knew I'd be using high wattage devices it was one of the first things I did.

RE: Adding Inverter for dry camping

Hi, The only effects on the 12 volt systems is that running the inverter acts as an added parasitic load. Of course, running 120 volt devices also tend to draw down the battery bank quickly, because of the Peukert effect. For example a 120 volt toaster may draw about 120 amps while it is on. That is expecting a lot from a tiny bank, so large draw items should be limited in the time frame they are used. It is needful to have some way to replace the energy used in operating the electrical items in the RV. I prefer solar for that. Mex makes a great point. 12 volt adapters are generally between 15 to 20% more efficient than powering the same device on an inverter. Does that affect any of the 12V systems? Like the water pump?

RE: Adding Inverter for dry camping

Hi, I added a 30 amp outlet that is powered by the inverter. Here is how I use it. 1. unplug from shore power 2. disconnect the converter (default setting is off) 3. turn fridge to gas 4. plug in the shore power cord to the inverter powered outlet 5. turn on the inverter. My goal was for my RV to operate at all times as if it had shore power. I succeeded in doing so. I prefer to not use transfer switches.

RE: autoformer

Hi Mex, I was hoping you would be one of the responders. Any brand name on the 20 amp and 30 amp? And/or internet sellers?

RE: Newb advice opinions

Hi, Solar can run everything in an RV with the exception of long run time high wattage devices, such as the air conditioner. When I was not full time, I would run out of water before I ran out of electricity. The same can be done with full time but it is best to fully populate the roof with panels. Many folks who have 600 watts of solar don't run their generators at all, assuming propane is used for the fridge. When they want air conditioning--they look for a cheap campground. It is generally cheaper to be in a campground than to run a generator for 24 hours. With 1200 watts of panels, in perfect solar conditions, it may be possible to run a small air conditioner. Pianotuna how well does the solar work? Can you stay off the grid reasonably well? I've been reading but never messed with solar.

RE: Charge Wizard light

Hi tarnold, The generator does not charge the house battery bank directly. The generator powers the converter, and the converter then charges the house bank. Piano, surely you are wrong about the gen not charging the house bat?

RE: Charge Wizard light

Hi, The wizard show a solid non flashing mode for 14.4 volts. Your last sentence doesn't make sense as the generator only provides power to the converter--i.e. the generator does not do any 12 volt battery charging.

RE: Furnace Gas Usage

Hi, If there is shore power and it is unmetered it is a no brainer to use it for space heating. If not, then do a cost comparison. I do heat nearly 100% electrically.

RE: Electric Fireplace or AC/Heat pump

Hi, For serious heating savings the heat pump shines at temperatures above 40 F. Much below that, and there is little savings. I won't go to a heat pump until the air conditioner fails. When that happens I'll upgrade to a heat pump model. I use electric heated carpets for a large part of the space heating needs.

Hi, Rent a unit and see how the "real deal" works out.

autoformer

Hi, I've decided it is time to get serious about an autoformer. Can I get one that would cover only the roof air (nothing else worries me brown out wise)? Or am I better with one that does the 30 amp service? Draw on the air conditioner was a whopping 1900 watts. The campground breaker did flip off twice. I did find a few days last summer where I was at a 30 amp RV campground where voltage was lower than I'm comfortable with. I did switch off the water heater, turned off the converter and moved the fridge to propane, but still had low voltage issues. What autoformer would you choose (link please) and why? I wonder if there is a way to use the Magnum inverter to do voltage support?

RE: Air conditioning on solar

Hi, I think run wattage may go up by as much as 30% during a super hot day. My next (big) purchase is going to be an autoformer. Last summer I had troubles with low voltage at campgrounds. It's not fun being too poor to replace items.

RE: Honda Generators

Hi, I used this after market remote: remote start kit Cost in USA would be lower on the generator. Hi, I prefer to have electric start so I have the Yamaha 3000 Sieb. I refuse to run a generator when I am sleeping so I added a remote control for it. Love the idea of a remote start! Mind sharing approx cost for your set up? Thx

RE: My Fantasy Package

Hi, Make sure you can purchase Chassis parts. I ran into that problem on my 1987 E-350. My opinion is that the unit is too old. It may nickle and dime you to death.
