RE: Solar Panels

Between 60 and 150 watts per 100 amp-hours of battery bank. This series of articles may help. https://freecampsites.net/adding-solar/

RE: total rewire/rebuild of 1979

My RV has wire rated for 15 amps on nearly all DC circuits. I think that would be a minimum. If I were starting from scratch I'd use wire that could handle 30 amps. The main charging wire from the engine to the house bank is rated for 60 amps. after the third failure, I replaced the fuse with an automatic reset 50 amp breaker. I deliberately went to 50 because breakers don't give the instant response that a fuse does. My lighting is NOT all on one breaker. That's a nice feature because I would not be trying to replace a fuse in total darkness. I've blown just one 12 volt fuse and it was my own fault. I accidentally connected a 500 watt load to a 400 watt inverter connected to a 15 amp 12 volt breaker. It blew instantly--which is exactly what is needed.

RE: emptying tanks ?

At least some Iowa rest stops have dump facilities and rinse water.

RE: Forklift batteries for a solar trailer?

Hi Mex, Plate warping in tubular cells from the jolts (i.e. high demand)? Or do you mean mechanical vibration? My favorite bank is still 800 amp hour two volt cells in series (Surrette). At 48 volts the jolts are not so bad for a 1200 watt load. Unfortunately I have a beer budget, so this may remain a dream until I win a lottery. Is corrosion the reason for pushing air rather than sucking it? The gasses you mention are why I don't approve of unvented battery boxes for AGM jars. They tend to be pretty deadly with even short exposure times.

Hi, Since my brother purchased it 2 weeks ago I have no idea about the rally.

RE: Forklift batteries for a solar trailer?

A much cheaper solution would be a generator and some long cords. If all the folks have hybrid inverter chargers then overload is probably not an issue. I would choose a 7000 watt inverter generator. BTW I prefer to run my RV 100% electrically including heating, cooking, and water heating. Since I got my generator replaced (the last one grew wings) I've run it for 18.5 hours (July 20, 2017 to Sept 22, 2017). I have not considered running an A/C with it, as this is more of a campsite item, where multiple people in a camp would be using this, not just me. Where this will come in handy will be in cooler weather to power things like Keurig coffee makers, microwaves, and cooking appliances, this will provide the ability to actually cook on electric without the need for a noisy generator, and with enough panel capacity, especially with five days sitting unused in Texas. Forklift batteries have not been mentioned, just because of the bulk. However, with my use for a camp at festivals where this is a static item, it just might be my ideal for what I'm looking for. Eventually, when I can get some acreage, it also might be able to handle power for a cabin with ease.

RE: Interested in any solar advice

No the battery is not charged. I had solar for 5 years as a part time rv'er and did not even own a generator. They are in a flat fixed installation and have given me zero problems since 2005. I wish I had spend the money to upgrade my solar instead of buying generators. So far the genny's have cost about $9000.00 Buy a good generator and avoid the BS. I dry camp away from the maddening crowd, when the crowd shows up I move. It almost became a game with me watching people trying to set up the solar panels for most exposure. If you are staying in one spot for a year maybe it may pay off, otherwise get a Honda or a Yamaha.You run it for 2 to 3 hrs a day the battery is charged.

RE: Forklift batteries for a solar trailer?

If you intend to run a roof air conditioner, 48 volts is the "way to go". The 12 volt needs can be met by using the converter and the OEM house battery. Or a 48 volt DC to 12 volt DC converter may be used. Each one of the fork lift jars has a capacity of 48,000 watts of which 24,000 may be used. That would power my roof air conditioner in HOT ambient temperatures for over 12 hours with no energy coming from the panels, without going below 50% state of charge. As someone else suggested, recharging may be an issue, particularly if you wish to equalize the bank on solar. I suspect that fork lift jars need a fair bit of power to prevent progressive capacity loss. It might cost more for a proper charger than for the batteries.

RE: An electric bus that drove 1,100 miles between charges...

Hi, Max continuous on 30 amp is 24 amps or 2880 watts. I use the Magnum hybrid inverter remote to limit my connection to 24 amps. I'm currently at a campground which has old and weak 30 amp. I'm having to use my sola basic autoformer to boost voltage. No load voltage is 113. Putting on the fridge 325 watts, two oil filled heaters 900 watts and water heater 1200 watts drops the voltage to 100. Using the autoformer boosts that to 117 when all the items are drawing power. While cooking breakfast (electrically) today the load support cut in, meaning I was drawing more than the 24 amp limit. I suspect that means that on the shore side of the autoformer that I was drawing 30 amps. The connection "order" is shore power to autoformer to Magnum to RV. Of course, lower voltage on resistance type heaters means less output. 30 amps x 100 volts = 3000 watts I suppose if I do not wish to tax the shore power connection I should set the limit to 80% of 3000 or 2400 watts. 2400 / 117 = 20.5 amps less 5% for overhead from the sola basic or about 19.5 amps. However, there is no "heating" happening at the shore power plug in, and no tripping of the shore power breaker, so I'll probably leave it at 24 amps. I did have a reservation for a 50 amp site--but they gave it away to someone else. I'm not too happy with them for doing so. Thank goodness I have the equipment to deal with lousy shore power! If you only have 30amp, it might be a couple weeks to charge or longer as the house loads will eat up a greater percentage of a 30amp supply (which is more like 25amp for continuous).

Hi Time2Roll, So per leg 6000 X 80% = 4800 watts.

RE: An electric bus that drove 1,100 miles between charges...

Your source is ancient history from 2013. I've seen retail prices for panels as low as 24 cents per watt. Solar is not there yet. If we remove all of the subsidies Solar still costs more to make the panels than they can produce. This article Solar panels claims this will turn around by 2020. But I suspect they assume electric rates will not change by 2020. Not likely as my Arizona rates just recently increased.

Hi, 9.6 per leg? 50 amp connector for continuous duty is limited to 9.6 kW by NEC

That distance record is impressive. However they drove 15 mph to do it.
