RE: Air compressors recommendations

+1 for MV50 for occasional use. As long as it clamps direct on the battery only, the compressor is probably fine up to 80psi fill. If it has a cigar plug stay away as it will be weak.

RE: Solar crunch time! Please review my plan.

Unless the budget is very limited I would always recommend aiming for the high side on solar. This allows for other than perfect circumstances. It is a myth to think you can size the system to consistently arrive at 100% charged just as the sun is setting. 150w per battery is the high side, 100w is about middle, 50w is the low side. JMHO.

RE: Inverter Efficiency 99% ???

Grid tie is 400+ volts in and 230 volts out so it will inherently be more efficient than any RV inverter pulling in 180 amps to make power. I also find European ratings in some areas are not quite as realistic as the US.

RE: Electrical questions, alternator? amps? generator?

Alternator is fine. 30 amp is fine... especially with no air conditioner. 2000w generator is fine to run everything else and charge batteries. Minimum 2x Group 27 or a pair of GC2. If you expect the inverter to run the microwave, hair drier, coffee pot etc you better have 4+ batteries. I would buy wire according to the load. That is a lot of power in roof lighting. I would have recommended LED. Diagram is a bit simplistic but is fine.

RE: Do in-tank fuel pumps give any warning of impending failure/

Can't speak for Chevy but my Ford gave some hard to start warning in cold weather. Then it failed when we went to the snow two months later :R Hindsight is 20/20.

RE: Wiring to charge trailer from my van's alternator?

As long as you are pulling wire I would go #10 or even #8. Use a step down splice if it will not fit the connector. Fuse for the smallest wire in the loop. 6" #14 will not stop the flow near as much as 20' of same. You are the relay... unplug when appropriate. Still may take a 5+ hour drive to get a good charge into a low battery. Dad probably does some significant driving along with good with conservation.

RE: Rare find. Used HD F150.

HD for sure but $35,000 seems a bit much.... Wonder how much more a 'real' 3/4 ton (8,600 GVWR) would cost? Betcha the OEMs make more $$$ on their half ton sales than their higher class salesOK and how much payload does that 3/4 have? +400 on GVWR, +1,000 on curb weight, + what for v10 or diesel? Better to go 1 ton if you are moving up.

RE: Whirring noise from inverter

It may be the converter, not sure about terminology. This morning the battery died, even though we had been connected to shore power. Should I replace the battery first and see what happens? INVERTER uses battery 12vdc to produce 120vac to power 120v items when camped off grid. CONVERTER uses 120vac to produce 12v power to keep the battery charged and power the 12v items in the RV. Dead 12v system (lights etc.) points mostly to a failed converter. Need to separate the battery and converter to test/verify what the problem is. Remove the battery and use a portable charger to see if it will charge. Your 12v systems should run directly from the converter. Post converter model for best suggestions on replacement.

RE: Whirring noise from inverter

Check your battery too. Water should be covering the plates, no excessive gassing, the terminals should measure steady 13.2 to 13.7 volts. If this is actually an inverter(vs converter) then disregard.

RE: battery charging> which is best

a is best if you have a good converter.

RE: Power Robbing Engine Valve Springs

I always thought a rotating ball valve would eventually work out.

RE: New electrical question

Need to either run the branch circuits 100% off the inverter or get two small transfer switches. http://www.donrowe.com/KISAE-TS15A-Automatic-Transfer-Switch-p/ts15a.htm http://cdn3.volusion.com/wvdcy.sjrgm/v/vspfiles/photos/TS15A-2T.jpg width=350 I have a 300w GoPower inverter with two transfer switches, works perfect.

RE: Solar questions?

Prostar does not look to be programmable. Temperature compensated 14.4 volts with 14.9 equalization every 25 days will keep your battery in tip top shape.

RE: 12 volt electrical

No, that is not what he is measuring. He is measuring ACROSS the fuse connector.Ah ha! Need amp reading instead of voltage. Then poke around to get the amps to zero. Kitchen is probably the propane detector... no switch to turn off and for good reason that it could be left disabled.

RE: battery charging

No. As the battery gets to 14.2+ volts, charge for an additional 60 minutes. This gets you to about 90%. 100% will take an additional 4 to 8 hours. If you have a fixed voltage converter you are slow charging at about 13.6 volts and you need 2 to 8 hours to get to 90%.

RE: 12 volt electrical

fuse #1 (lights) tested 11.43v again no fuse in fuse #4 (furnace) tested .93v fuse #5 (radio) tested 12.34v fuse #7 (kitchen) tested .05v the other 4 terminals tested 0 volts. why was there volt present in some terminals and not all ? any thoughts appreciated.............ss Just to clarify... ALL fuses are pulled and you are measuring voltage at the fuse connector, yes? Battery voltage on one side and these listed voltages on the other side, right? I also would expect all to be zero with fuse removed. Something appears to be back feeding these circuits. Furnace might have something to do with the thermostat. Radio could be an antenna booster? Lights, no idea. Kitchen, fan? more lights? no idea. Try grounding them for a moment in case there is a circuit board with a capacitor. Time to pull the power center from the cabinet and take a look behind.

RE: Inverter powering only one outlet

The TV and DVD do operate on the inverter. During trouble shooting I've been establishing the lack of power to elsewhere in the RV by checking the microwave and plugging in a working 110V night light to each outlet.Does the inverter have 120vac coming out?

RE: Solar questions?

You might be surprised how well the 24 does with 100 amps of solar. I would give it a go as is.

RE: Installing inverter in 50 amp system

The GP3000 can power those items full time or you can install a 30 amp transfer switch. Pop a 30 amp breaker into you main panel to feed one side of the transfer switch. Inverter feeds the other side of the switch. Transfer switch will choose one of the two and feed power to the 30a subpanel. PD5100 switch 30a $83 Yes you will move the branch circuits you want to run on inverter power..... off the main panel and onto the subpanel. Yes you should have six+ batteries to properly drive 3000 watts of inverter. > Forum Members Solar Installations With Pics
