RE: Tapping off of the 3/8 Propane Line

RE: Trick the WFCO converter into not entering 14.4v?

red31, the OP is using the wfco without a battery. so! A dead battery (after wfco tried 14.4/max) would keep the wfco in bulk for 4 hrs, if no or good battery wfco goes to 13.6v since the load doesn't draw the voltage too low. wfco troubleshooting without a batt = 13.6v

RE: Trick the WFCO converter into not entering 14.4v?

Is there way to keep this converter from going into 14.4 charging mode? The general issue with WFCO is it won't go into 14.4v charging. Is there something happening to make you believe it is doing 14.4v

RE: Mach III plus 13.5 ac fan running backwards?

not the cover that changes where air blows/sucks but the A/C itself http://bryantrv.com/images/roofairjgif.jpg

RE: Mach III plus 13.5 ac fan running backwards?

Wax, tell us how a capacitor is used to create torque in AC motor? In short, a capacitor creates a 2nd phase. Here's a pretty decent page to help explain this. Refer to the capacitor-start and capacitor-run motors: https://www.allaboutcircuits.com/textbook/alternating-current/chpt-13/single-phase-induction-motors/ that's it Capacitor-Start Induction Motor 'The result is that more starting torque is available for heavy loads like air conditioning compressors.'

RE: Fridge temperature depends on ambient

ajriding, your 442 is supposed to have a capillary tube thermostat that would cause the flame to go into low flame mode when cold enough.

RE: Fridge temperature depends on ambient

sorry Doug but my info comes from the MANY PUs out there (www.popupportal.com/) that need to turn their fridge down at night to not freeze the lettuce, didn't take me anytime at all to understand their issues of no burner thermostat & bad installs like mine etc. The RM 2193 only has a therm on AC not gas or batt! The norcolc 323, 206 NO GAS THERM. Yes the PU folks appreciate being oddballs, they get that stuff all the time, lessor campers as you know. we've been through this before.

As a manual reader I've seen this in both norcold compact and dometic https://i.imgur.com/nvJ0Md4l.jpg Maybe the OP could share what fridge is in his truck camper?

RE: Fridge temperature depends on ambient

some of those small fridges sans freezer DO NOT HAVE A TEMP CONTROL (thermostat), you are the thermostat, the propane flame is adjustable from small to smaller.

RE: How to I Set up my Portable Solar Panel

Solar Ready outlet. I am buying a portable solar panel. Do I just plug it in or is there more to it? if the brand of plug is different from the panel kit it would be best to determine the polarity of the kit and plug to determine they are the same. Zamp solar ready likely be backward from others! rewire it or get the adapter but check the polarity

RE: Solar Controllers PWM MPPT Temperature Performance

It is not whether or not NOTC works for you, it is that NOTC info shows that panel get hot as you know, they get hot even with 80% 'sun'. The biased white paper shows when PWM=MPPT, this is a large range, bigger than the blue shaded area, I'll suggest 40-100C

RE: Solar Controllers PWM MPPT Temperature Performance

Many panels have published NOTC. This test is @ 80% or 800 watts per square meter vs 1000. 20C air blowing on the panel @ 20C. 45C temps in these conditions! with a breeze and space behind the panel for air flow. "Both conductive and convective heat transfer are significantly affected by the mounting conditions of the PV module. A rear surface which cannot exchange heat with the ambient (i.e., a covered rear surface such as that directly mounted on a roof with no air gap), will effectively have an infinite rear thermal resistance. Similarly, convection in these conditions is limited to the convection from the front of the module. Roof integrated mounting thus causes higher operating temperature, often increasing the temperature of the modules by 10°C." https://www.pveducation.org/pvcdrom/modules-and-arrays/nominal-operating-cell-temperature

RE: Solar Controllers PWM MPPT Temperature Performance

the full white paper is informative although I believe biased as one can see in the graph fig 15 (chapter 7). The problem is their comparison includes series connected panels for MPPT! Well additional voltage above batt from somewhere! "Let us now assume that the MPPT controller is connected to a solar array with sufficient cells in series to achieve an MPPT voltage several volts higher than the highest battery voltage." Full white paper It is hot here! All I need to do is look at fig 15 and see that PWM is above the 90% line in the temps of concern. The MPPT line should mimic PWM when Vmp is less than batt voltage as seen in chapter 5. Vmp drops with heat! "Most MPPT controllers cannot transform a lower voltage to a higher voltage, as that’s not what they are made for. If the MPPT voltage Vm becomes lower than Vbat, they will therefore operate like a PWM controller, connecting the panel directly to the battery." to me the 90% line represents the bucking eff. With regular controller limiting power in abs and float it just don't matter much then you go series (wiring. light and heat) and ya need MPPT.

RE: Question about the output from my DIY Solar

Isc and Vsc pair or Ioc and Voc. by definition Vsc is zero & Ioc is zero. both zero power conditions at each end of the IV curve. Isc and Voc are the max, current and voltage shorted again, clamp meter 2:40 https://www.youtube.com/watch?v=57R5CVi1j_k

RE: Question about the output from my DIY Solar

can you rephrase your question using Vsc or ZERO volts when + and - are connected via no resistance. Clamp on should match ammeter with 8A reading shorted by a wire or shorted by an ammeter. Short circuit current, short is in its name and definition! see it done @ 2:15 of this video! https://www.youtube.com/watch?v=hOjcaKmR4lE

RE: Question about the output from my DIY Solar

yes, short panel via an ammeter (or short panel and use a clamp around ammeter), no need to do this test at this pt., add loads and/or discharge the battery to see if additional power is made.

RE: Question about the output from my DIY Solar

controller job is the LIMIT panel output, if your battery is charged it does not take much power to keep it there. Yes, if there is a need for power and it CAN be made it will be used for whatever load you have and/or to recharge the battery.

RE: Electrolysis

worked the mag cells in Freeport, TX. Chlorine spell all around. Some of the magnesium was buried all over the other sections of the plant, not only sacrificial but made nice parking lots.
