RE: No DC power to trailer, batteries good

Get out your multimeter. Check that you have power on both sides of the battery fuse, then check both sides of the cut-off switch, finally check power as it comes into the 12v distribution panel. At some point you will find 12v on one side of something and zero on the other. Clean, tighten, or replace that item. And yes there are sometimes a breaker that is well hidden with poor access.

RE: compact fridge

Hopefully no as I have 2 group 31 batteries and 170 watts of solar.Generator back up? Otherwise you may need to double the ratings. BFL13 just had a thread on this. Read here

RE: Why don't RVs need an earth ground for AC circuits

Sometimes I just trust the professionals and the code book. I let it go at that.

RE: 50A connector difficult to remove from power source

If you get a straight plug instead of the 90 you could just have the RV pull it out :B

RE: 48 volt dc air conditioner and solar needs chart

I agree that no one who is attempting to run an air conditioner would worry about having too many watts of panels.Yes and I think 95% conversion of rated watts getting to the air conditioner is a bit optimistic. Hence my WAG to increase panel rating by 50%... not just to have extra.

RE: My Ac/dc converter caught fire last night

Never heard a WFCO on fire and the steady voltage with or without a battery should be a step up. Not to mention the far improved distribution. 8955 should work fine.

RE: 48 volt dc air conditioner and solar needs chart

http://www.geinnovations.net/Specifications.html Check the power input specification. 12,000 BTU 560 watts 15,000 BTU 770 watts 18,000 BTU 1368 watts The OP link gives the 95% panel to load efficiency assumption. Math seems to be a very simplistic spreadsheet. No calculus here.

RE: Battery Question

+1 to run them down to 12.1 (~50%) with a light load and recharge 48 hours. Then hydrometer check.

RE: Winter Storage Question

With AGM I would either use the solar (no cover) or full charge and disconnect the battery. No need to have a cord out to trip over.

RE: 48 volt dc air conditioner and solar needs chart

12,000 BTU says 560 watt load. So the calc is just a simplistic 589w(solar) x 95% = 560w(load) I would plan on 50% more panel than the chart shows. Need lots of battery to get through a hot night. Going to lose significant efficiency in the battery to go 24 hours even if only 18 hours run time is needed.

RE: regular extension cord to run some appliances

Plug the cord into a power strip with a 15 amp breaker. If the breaker trips reduce the load and reset.

RE: Batteries

Best will be to keep the battery charged year round with solar.

RE: Orange County Register Article - RV Storage

However, it is closing about 2 years sooner than predicted.When I moved in ten years ago I was warned that it could close in 6 to 18 months. Moved last month due to rate increases. Yes a little more distance but half the fee is worth it.

RE: Disconnecting front axle disc brakes

I would just turn the controller down a bit. Brake more gradually. This is the safest way to get home. JMHO.

RE: Ecoworthy MPPT + 6 volt batts

Even 14.8 is probably higher than needed especially when not in use. I would go down to 14.4 volts Absorption. 13.4 Float is fine. Check with a hydrometer in six weeks to verify you are getting full charge. Check water usage more frequently as you go 14.6+ volts. May not be an issue with new batteries.

RE: Modification ideas for boondocking

Diesel? I meant to just 12v pump some water from the existing water heater to a simple baseboard hydronic heater. www.zoro.com/classic-architectural-closed-loop-heater-white $136

RE: WFCO WF-8900 Not Charging

A portable 10+ amp automatic battery charger will do fine to get you through the trip. Not much good to say about WFCO except it is the low cost option of replacement. www.bestconverter.com/8935MBA-Main-Board-Assembly-For-8935 I recommend the 30 amp IOTA with IQ controller www.bestconverter.com/DLS-30-30-Amp-Power-Converter-wIQ4

RE: Modification ideas for boondocking

1) I would pass on trying to use the ducted air conditioner vents to distribute air. Far better to just use a 12 volt fan to distribute air. Amazon - Endless Breeze I would just cover the hole to make more space for another solar panel :B Fantastic fan or equivalent in the bathroom is plenty. 2) Again the air distribution will be poor until the stack of muffin fans makes as much noise as the furnace. See fan above for better solution. Alternatively get a two speed furnace to run on low speed at night. 3) More work than the propane savings will ever pay. I would be more inclined to use the hot water from the heater to warm the trailer with a radiator. This should prove to be quiet. Just my random thoughts. Best of luck and post some pictures.

RE: possible converter problem or ?

If the fan and voltage are jumping up and down in a random pattern the converter is probably shot. Most converters should also hold voltage steady with no battery... try it. WFCO?

RE: Differential swap

Well, I went ahead and swapped differentials for 4.56 gears. I was also talking with guys on the Ford Super Duty site. I might regret this as some of you have indicated; time will tell. I think I'll be picking up the truck and trailer this weekend. Will let you know how it performs on the way home.Where is our trip report? ;)
