Thumbs up FYI. Solar Installed and First test Run

We have installed a solar system on our 8260ws Ultralite Rockwood 5th wheel. The system includes 2-200 watt panels, Tri Metric battery monitor, Tri Star 45 amp controller with temperature compensation, Samplex 1500 watt pure sine wave inverter and 4 Trojan T-105 6 volt batteries which equals 440 amps of storage, with 300 amp fuse. The panels are wired with number 4 wire from the panels to the front storage bin with the shortest distance possible to the batteries and tri star controller. Batteries are 2/0 wired between each other, crimped and shrink wrapped. Wiring to the shunt is also 2/0. All wire sizes to components are either #4 or 2/0 in close proximity to each other to avoid any unnecessary voltage loss. In our test period of mid Sept to mid Nov we spent 75% of camping time dry camping or boon docking . The system provided enough power to never tax the batteries below 94% , or 12.6 volts. Every day by early afternoon the battery charge was a full 14.6 or 101% percent charge. The tri metric 2025 is awesome. It allows us to check every thing we use and tell the exact amount of amps each item consumes. The list below is what we used every day with no concern, 900 watt toaster, lights, ceiling fan, stove fan, genesis sound system for music,TV, DVDs, charging phones, iPod, ipad, camera, vacuum cleaner, furnace in the morning as needed and curling iron. Will not run air and only short time with micro. Our solar experience is working as planned, generator free and makes for very happy campers.

Excellent write up.

I plan to build a system with 2-245W Sharp solar panels (36v), TS-MPPT-60, Tri Metric battery monitor, 2000 watt pure sine wave inverter, automatic transfer switch and 2 Trojan T-105. All using the largest wire possible.

Question 1:
I've read that using a coffee maker will drain batteries very quickly. Do you use a coffee maker.

Question 2:
With normal use, radio (during the day), TV (2-4hrs day), LED lights, power for laptops will I be ok?

Re your new solar plan

Thanks for the response any help we can share when using or planning solar helps us all get a better system. The system you are planning is very similar to the way we are set up. A coffee maker should not require much more than a toaster and I just prefer to make drip coffee. The watts required for a coffee maker range from 900 watts to 1400 watts, check wattage before you purchase. The tri metric battery monitor will be your best teacher as you navigate the amperage of every thing you plan. For example when you turn on the coffee maker your tri metric will tell how many amps the draw is on the battery. Lets assume the tri metric reads 100 amps, multiply that by the 12 volts and the watts of that appliance is 1200. When the inverter is on you can see the amps it's taking from the batteries. The tri metric gives us a look at percentage of the battery left for other usage, 94% means we used up 6%. The heart of a good solar experience is to have enough amperage storage. The two Trojan 6 volts t105's is 220 amps and will be a factor in keeping up with the demands you put on the system. Add two more t105's doubles the amps available to 400 amps.

The plan you have should give you all the power to recharge and keep you out of trouble. PS t105's need to be charged to 14.6 volts. Make sure the controller gets them to this point and doses not under charge them or float to soon. Hope this answers some of the concerns. Happy camping Bruce

thanks for the information. When I charge my batteries with a 6v charger they get to 6.43v on battery #1 and 6.40v on battery #2. I hear them bubbling pretty good.

Is this ok?

6volt charging

Your 6 volt battery test of 6.4 volts are near the Trojan recommended 6.6 float level. The bubbling sound is a good sign and is normal, keeps the plates clean and inhibits stratification which is a battery killer. Trojan Battery Company
click on charging and refer to chart. Enjoy your day, Bruce

Just a point of clarification so we are all talking the same language.
Battery capacity is measured in Amp Hours or Ah.
Instantaneous current is measured in Amps.

The T-105 is rated at 220 Ah at C/20 load.

An alternative to the elect coffee pot is the old fashion stove top perk coffee, you'd be surprised how GOOD the coffee taste from these pots, and NO elect useage.

Amps or amp hours

Thanks Glenn, you are so correct amp hours are much different. Happy camping!

Do you have any photos of the project posted??

Also, what panels did you use and do you perhaps have a cost breakdown of everything??

I have been thinking about doing something like this and want to jump in this year
