And since you have gone that far, get the stand alone Renogy 100w panel. Way less than go power.
Both Bogart Engineering ( Trimetric ) and Renogy are great people to deal with.

Thanks for the suggestion about the Trimetric 2030 and the 30A companion solar controller SC2030. However, I definitely want a flex panel and not a rigid panel, especially not one that I have to carry and set up. If I went with the Go Power 100w flexible panel instead of the cheaper Renogy panel, would I need the 30 Amp Go Power solar controller if I bought the Trimetric set-up?

I'm pretty sure Renogy makes a flexible panel as well. In fact I just looked and you can even buy them at Amazon.

I have 3 100W Renogy Flexible panels and they are performing as promised. Look on their website.
Also you won't get any better support than you will get from Bogart Engineering. I just had an upgrade on the TM done. I paid the shipping, the update was free and they shipped it back and reimbursed me for my time and trouble.

George, what was the update on the TM2025 all about?

The update was for the TM2030 which I have working in conjunction with the SC2030 controller and it was more of an upgrade to allow another set point so that there would basically be a one button equalization process.

I have 2 of the flexible renology panels and I store them under the mattress. MUCH better than the big solid panel that filled up the truck bed.

OK, thanks, not for my unit.....thought I missed something.

Great Idea. I store my 3 on the canopy of my truck all ready to hook up!

Now, about ordering a Bogart Engineering SC-2030 controller with the Trimetric 2030RV version 2.2 monitor to use initially with 3 100-watt Renogy flexible panels, but possibly with more panels added in the future, should the Bogart equipment be purchased with a 500 amp or 100 amp shunt?
http://bogartengineering.com/sites/d...SHUNTInfo2.pdf

Application Notes | Bogart Engineering

It looks, from Bogart's FAQs that 500 amp would be best in the long run:

D. Shunt Frequently Answered Questions – Click for questions
D1.Which shunt should I use in my system ?
Click for answer
The two choices are the 500 Amp/50mV shunt or 100 Amp/100mV shunt. The most common choice is the 500A/50mV shunt. The deciding factors are the MAXIMUM amps that you will either charge or discharge with your system, and the highest "amps" resolution that you want to see on your meter. Usually this is determined by your maximum loads on the battery.

The 100A/100mV shunt will likely overheat if your system if charging or discharging your batteries over 70 amps, so in that case you should use the 500A shunt. Going over this value will not harm the meter--however the shunt can overheat with too many amps. If you have an inverter, converter, or loads with a 12 volts system that exceed 800 watts (or with 24 system 1600 watts) then that will likely put you over the 70 amp limit. For example, using a microwave would usually exceed 70 amps in a 12V system. With the 500A/50mV shunt you will be able to read "amps" values down to 0.1 amp. A 0.1 amp draw in a 12V system would be represented by a 1.2 watt load. With a 24V system it would be 2.4 watts.

If you have a smaller system there is an advantage of the 100A/100mV shunt, in that you will be able to read amps values on the meter as low as 0.01 amp instead of 0.1 amp. This would hardly matter in a large system, but in a smaller system you may want to able to see really small loads. 0.01 amp would allow you to see loads down to 0.12 watt loads.

----------
Another part to purchase is the Bogart Engineering TS-2 temperature sensor, which I gather would be helpful.

Do any of you have a favorite vendor for Bogart components? Here are some:
17 Bogart Engineering SC-2030 Solar Charge Controller

TriMetric Battery Monitor

Alt E Store - Search Results for Bogart

Do you have favorite vendors for Renogy solar panels?

Flexible Solar panels... Opinions?

OK, you guys have convinced me, Renogy & Trimetric.

I found my solar prewire today and both ends are terminated in crimp connections. It looks like the Renogy comes with MC4 connections, and if I cut them off I void the warranty (that may not be the main problem if I tape the panel down, since I could never get it off in one piece). Would you recommend cutting off the MC4s or cutting off the crimp connections on the prewire and adding MC4s?

When I ordered my TM2025, Randy recommended the 500Amp shunt, but I can't remember all the whys. You are correct that the resolution of the 500amp is only to the tenth, whereas the 100amp is to the hundredth.

You may want to call Randy, at bestconverter.com to discuss.

Marty, your 300-watt Renogy setup with the TM2030 and the Bogart SC-2030 sounds like just what I am planning to install, except I'm going with rigid panels. All things being equal, what battery setup will you have? I want to leave room for expansion (and a possible inverter) in the future. Also either two of the Lifeline GPL-4CT or two of the GPL-6CT AGMs. Is this enough? We don't plan on using the air conditioning or microwave when boondocking; have all LED lighting and catalytic heater. Thought I'd leave room to expand to four of the six-volt AGMs if need be. I'm curious to know how you will configure yours.

Of course, a year earlier, the Wynns were dancing around on the flexible panels, which was abusive: Powerful and Flexible RV Solar Panels
