RE: surge protection

Hughes now has an autoformer that does surge, and polarity checks. Since there is a lot of "hidden" damage from low voltage this "pairing" makes a great deal of sense. https://hughesautoformers.com/ https://hughesautoformers.com/wp-content/uploads/2015/06/led-display-home-trans1.png width=350

RE: Generator suggestions

Cite the basis for that statement as a non-inverter generator puts out a pure sine wave. An inverter generator can put out a modified sine wave or a pure one depending on the design and filtering. Hi avvidclif1, This is from a thread on wave forms. Pretty lousy I'd say. Surprisingly, my 5500 onboard Onan is the worst I have seen so far. I am posting it next. It is worse than my 2 sub $1000 Champions. I will say it is the quietest onboard generator I have ever heard.

RE: Renogy help

What make size and type of battery do you have? Usually they want the capacity in amp-hours at the 20 hour rate.

RE: killer deals on inverters and solar

Hi, The inverter will eat your lunch. Cooling fan runs constantly. Aims is not highly respected. Panel prices are amazingly low.

Some folks have plenty of the green stuff to brag about burning.. I don't.. X2

RE: Need Battery Help ASAP

Hi, For $340 you could add 170 watts of solar. I just upgraded to two Trojan T-105RE 6v batteries...cost $340 Add either a generator or solar for recharging and you're looking at a lot more money.

RE: unlimited data plans

Hi, I decided to order the Samsung Tablet that allows tethering. I'll let you all know if it works in Canada.

RE: Need Battery Help ASAP

For boondocking one week a year it seems silly to have two large capacity jars. It would be better to invest in a modest solar system. Costs for DIY are about $2 per watt for parts and materials.

RE: honda 2000 generator with solar panel assist..

Mr Wizard, I do "see" 17 amps at solar noon when I'm forcing "voltage support", so that works out to around 217 watts, or a about 2 amps @ 107 volts. Why 107? Because that is the bare minimum voltage that I'll run the roof air at.

RE: honda 2000 generator with solar panel assist..

Most grid tied inverters are 240 volts. That may not be easy to deal with in an RV.

RE: Low Voltage Hair Dryer

Move to a hybrid inverter/charger. It will supply the extra power needed for the air conditioner/hair drier combo by drawing energy from the battery bank. Then after the hair drier is turned off the batteries will recharge from the generator.

RE: honda 2000 generator with solar panel assist..

Hi, What you want to do is possible with a hybrid inverter/charger, but with a twist. I am often in situations where I wish to do voltage support due to low shore power voltage. I found out that if I "dial down" the allowable amperage enough then the voltage is supported. My solar panels send energy to the battery bank--and the 120 volts AC power systems in the RV draw from the inverter. I have done the same thing with the generator, just as a test. I don't really understand why you are attempting to do this, unless it is because the battery bank is fully charged and you wish to continue to harvest the maximum amount of energy you can from the panels. If that is the case, with some charge controllers you can do a diversion load and send the extra harvest to a 12 volt element in the water heater. Grid tied inverters require a source of 240 volt AC power before they will transfer energy from the panels into the grid.

RE: Need Battery Help ASAP

Hi, Does the trailer have electric breaks? Is the breakaway switch set up to be "off"?

RE: Generator suggestions

Hi bpounds, That is why I recommended the Champion 3500 inverter generator. It has an electric remote start. Realistically, how many times will you want to get out and start the generator? Maybe you should consider electric start. Can your wife/kids start it if you are not around? Should you consider auto-start with a transfer switch? r you could run just one.

RE: Question about using Anderson levelers

Naio, I also had one break in half. That was most disconcerting in the middle of the night. If they were longer, went up higher and had less of a curve I'd possibly like them better. I did not enjoy driving "off" the end of them. They skid if you try to use them with wood under them to give extra height.

RE: Question about using Anderson levelers

Hi Naio, I bought a set. I gave them away. I'm back to using wood.

RE: Generator suggestions

Hi, I own a Yamaha sIEB 3000 watt (2800 VA) inverter generator. If I were buying tomorrow I'd purchase the 3500 watt Champion inverter generator.

RE: Solar project started

Hi, Outback makes great stuff, but so do Magnum. The 3000 watt Magnum is a hybrid unit with a larger charger, and if you purchase from Imarine is cheaper than the Outback 2000 watt unit. I've found out how to "trick" the Magnum into doing not just load support, but voltage support as well. In the short term (say ten hours, depending on the size of the battery bank) this obviates the need for an autoformer.

RE: Denver CL, 245w panels $150 new

Nice find Jim.

RE: Generator runs until AC starts

The start up surge from the compressor is overloading the generator.
