RE: This Solar-Powered RV Runs Without Fuel Or Charging Stations

I wish I could afford such a wonderful unit.

RE: Can I replace 12v light switches with 110v house switches?

Hi, I'd buy dc rated switches. Size is a problem if going from RV to household.

RE: GFCI won't reset

Hi, Check the outlet at the house. If there is power, then check the cord to the RV. Is the outlet at the house 30 amp?

RE: Revenue Canada VS the IRS

Here is a link to the form. https://www.irs.gov/pub/irs-pdf/f8840.pdf As a Canadian we get an "automatic" visa for 90 days. If you plan to stay longer, you should apply for an extension. We can only stay 121 days per year if going south each and every day.

RE: Revenue Canada VS the IRS

If you end up paying ONLY USA tax, then Revenue Canada deems that all your Canadian assets have been sold and you get to pay capital gains on everything (except perhaps a TFSA account).

RE: For anyone wanting a 350 watt pure sine wave Victron

Hi LittleBill, You will need to do an adapter of some kind. The Victron comes with #8 wire (or maybe #6) which goes inside the case. I'm going to try running it on cigarette lighter, too, but will limit my demand to a laptop and heating pad. I'm concerned about the inrush current. i bought one, hope i can adapter a cigarette lighter to it easily, its 88 from boats and rv

RE: 3000W Chinese Gensets Info.

Hi Mr Wizard, I don't think it does. The remote start/shut down is a kit from Pinella's.

RE: Gas Chassis battery

MrWizard, I got nine years out of my Everstart Marine jars. I was part time then at about 90 nights a year.

For anyone wanting a 350 watt pure sine wave Victron

Hi folks, I find this an amazing deal at 90 bucks. I purchased one and it is double the weight of the inverter I was using before. https://smile.amazon.com/gp/product/B01EW5ZA94/ref=pe_344980_272415450_em_1p_0_ti

RE: 3000W Chinese Gensets Info.

Hi 72Cougarxr7, I have start up covered because the Magnum inverter/charger doesn't transfer power immediate. I wanted to know what the spin down does when shutting down. I do have remote electric start on an Yamaha 3000sIEB. (and of course remote shut down).

RE: Battery monitor

Smartgauge or Victron are both better than Trimetric. I spend the money for an amp-hour counter on more batteries. I do monitor voltage and use a watt meter.

RE: 3000W Chinese Gensets Info.

Hi Mex, At least I know what to ask about now. TY as always.

RE: Gas Chassis battery

Hi, After you have that nice new battery add a Trik-L-Start to prevent it dying again.

RE: ISB Sola Basic advice?

Does anyone have a picture of the single turn pot? My Sola did switch fast enough to support the air conditioner--until I got the Microair unit--now it doesn't so I'd love to adjust the pot to 112. We also learned that here is a small single turn pot on the circuit board so we could adjust the switching points as ours seemed to switch about 108 rather than 110v. It is GREAT to find out about this! Ours would not switch enough or fast enough to allow our heat pump (AC) to start. The voltage dropped too much so that the inverter kicked in to allow the compressor to start then reverted to the line voltage. This hard use eventually killed the inverter (Xantrex prosine 2.0) We're not in Mexico this season but I'll try that in the fall.

RE: ISB Sola Basic advice?

Hi, Yes, I think I am, but I did not realize it was buck only. You are probably talking about the other one I have. I'll try to remember to look tomorrow and post back here what it is called. It only guards against over voltage though. It won't raise a low voltage. but otherwise it's regulation is excellent.

RE: Battery question

Hi 2oldman, But I do follow your links! I learn all the time--sometimes even from new questions that are phrased in a different way making me reevaluate my answers.

RE: 3000W Chinese Gensets Info.

Hi, What are the issues regarding the generator when stopping an inverter generator "under load"? That being said, you just learned a costly lesson, a generator should never be started to shut off with a load on it. Unplug the generator before starting or shutting off.

RE: Advice on deep cycle setup?

Hi, I can't answer about Grape times--but voltage for each stage is (apparently) adjustable and it does have the necessary temperature sensor. Find data sheets and manuals here: http://www.grapesolar.com/manuals.html

RE: Advice on deep cycle setup?

Higher voltage means less line loss (less voltage drop), but to get the full benefit a good MPPT controller must be used. Charging may start earlier in the day and run later in the evening with MPPT. Losses from heat are slightly worse with MPPT. PWM may be used with a 24 volt panel but since PWM operates at slightly above the battery volt lots of energy will be dissipated as heat inside the controller. Electronics hate heat. They tend to hate over voltage as well--but some controllers can tolerate that. Personally, over 21 volts I would consider MPPT to be a better choice. If you want every last erg of power and have deep pockets, then go MPPT. For a 200 to 400 watt system I would go with the Grape 40 amp controller because it is fully featured, easily available at Home Depot, and inexpensive. With an initial 200 watts it leaves considerable room to add more panels in the future. I do not know of an MPPT controller that is inexpensive AND fully featured. When panel costs were $5.50 per watt MPPT made a lot of sense even for small systems. But with panel prices under a buck--not so much. Once 85% state of charge is reached, the acceptance rate of a flooded lead acid battery bank may cause an MPPT controller to operate in PWM mode. That percentage will be higher with high quality AGM--perhaps as high as 95%, but I have not found any documentation for that number. If anyone has some wisdom on why/how to go with 24 volt panels instead of 12 volt panels, I'd be interested to hear it. Thanks, L

RE: Flexible solar panel longevity?

Griffon12, There are thousands of makers who probably just buy panels from the big guys and then rebrand. The issue is lifespan.
