RE: What gauge wire?

Hi Salvo, You know that pwm doesn't control voltage so the top 2.6 volts on a 17 volt panel don't matter a hoot, assuming a 14.4 charging voltage. #10 wire is good for 30 amps. 280 watts/12.8 volts =~22 amps max. If it were an MPPT controller then wire size matters big time. My personal choice was and would be MPPT with a series connection for the panels.

RE: solar power battery maintenence

Hi, The bare minimum is about 30 watts per 100 amp-hours of storage. However, it may cost more for a 30 watt panel than for a 100 watt one. A true case of "more is less".

RE: 12V LED TV options

Hi Gde, Then use a buck to control the voltage.

RE: 12V LED TV options

Hi, They use a kill-a-watt meter because they do not have an ammeter. Bypassing the power brick is the way to go if it is possible to do so.

RE: What gauge wire?

Hi, #10 will be just fine with a pwm controller. I would add a temperature sensor.

RE: Is a motorhome "Only For The RIch"?

Hi, Compared to most of the rest of the world North American's have a high standard of living. We are lucky beyond belief to have the privilege of ownership of an RV.

RE: solar power battery maintenence

Here is a simple flow chart. Budget-->Energy Audit-->Battery bank size-->number of watts-->PWM or MPPT. What ever type of controller is chosen, make sure it has adjustable set points and a temperature probe that is on the battery. One rule of thumb is between 60 and 150 watts of panels per 100 amp-hours of storage. The smaller the battery bank the higher the wattage needed (per 100 amp-hours). Here is a link to the rather special spreadsheet which includes an energy audit, that N8GS has created to help size solar battery charging systems! Solar Spread Sheet N8GS For a nice explanation of solar, try this link: Golden rules of solar

RE: Battery monitor: useful tool or toy?

Hi, You need an amp-hour counter with AGM batteries. I'd recommend the one from Victron rather than the Trimetric. 600 amp-hours is a nice bank. What jar size the the six volt batteries? Are they wired in a balanced manner (this is possibly more important for AGM chemistries).

RE: Low Voltage on 50A - A First

Hi CAtraveller, I saw 106 today on the pedestal which is 50 amps. I'm heating 100% electrically again this year. I use a break out box which gives me a 30 amp outlet on one leg, and twin 20 amp outlets on the other leg. I have 3 shore power cords, the oem 30, a 20, and a 15 amp. I'd love to have an autoformer--but I want one from Mexico that has more than one set of taps.

RE: Measuring V loss during charging

Hi, I wonder if there is a case to be made for using the setting for AGM batteries when charging flooded batteries via a generator/converter, or generator/inverter/charger?

RE: what size genny????

Hi, A non inverter gas genny runs at 3600 rpm. The diesel runs at 1800 rpm. That explains most of the difference. I would recommend either a Yamaha 3000 sIEB or a 2000 watt unit combined with a hybrid inverter. I've noticed those diesel gennys, too. They're amazingly quiet - I don't know how they do it. Just a quiet hum even from outside.

RE: Grid Tie Inverters with Generator

Hi BFL13 found a 2000 watt hybrid inverter for $700.00 That would do the trick. I'm loving the Magnum I purchased.

RE: Very Inexpensive Battery Maintenance Charger

Hi, For the generator recharging crowd, do lifelines tolerate less than 100% recharges? For the solar fraternity, how much wattage is needed per 100 amp-hours of lifeline battery to get them from 30% to 100% in a day?

RE: ?'s about AC, Electric in BR and and thank you!

Hi, It sounds as if your rv is equipped with an inverter, but it is wired in such a manner as to not power all the outlets. It is becoming more common for RV's to have an inverter. It would be possible to move the outlet you need to the same circuit as the bathroom--but it might also mean having too many outlets on one breaker. Proceed with care. It is probably better to have a separate thread for each question.

RE: Fridge power consumption and operation

Hi Limoges, Four of my batteries are 10, the others are 5 years old. It is about having enough battery capacity, and recharging to 100% when ever humanly possible. Using it in electric mode, be it in 120VAC or 12 VDC uses up more of the battery's power than the propane does of the total available capacity, thus the effect of using it would be quite noticeable in battery drain. another reason to not use the battery/inverter is wear and tear on the battery: the more you use it, the less sooner it dies.

RE: Below freezing nights

Hi Read about it here: winter camping fridge Norcold does sell a cold weather kit. Hi, Best to protect the fridge, too. This is new to me, can you please let me know what you mean?

RE: Replaced 13500 A/C's w/ 15500 A/C's

13500/15000= 0.9 so expect about a 10% improvement. Outside awning shading the windows would be much more of an improvement.

RE: Advice on buying USED motorhome

Hi, Motor homes are filled with plastic parts in the "house". Plastic become depalmerized over time and those parts become brittle. Expected life span may be in the region of ten years. For that reason, I'd look for an RV that is only five years old. The #1 item to look for is any signs of water leaks or damage. If you see the barest hint--run away.

RE: Replacing a 55 amp converter with a 45?

Hi, I have 66 gallons of fresh water. It takes less than 30 minutes for the pump to empty it all. Conclusion--4 amp-hours of battery capacity is used. The pump is high draw but the duty cycle is extremely tiny. The furnace is a different matter altogether and needs lots of battery capacity. When temperatures are below freezing the furnace may use as much power in one hour as the pump does to empty the water tank.
