good to go, no worries. There might be days when you only get one hour of sun. Or days with no sun with some catching up to do the next day. Otherwise the MS-60 will keep your batteries ready to go at all times.

Hi,
That's a great choice.

You mentioned the TS MPPT-60 does diversion loads
I was not aware that controller could can do that function without additional hardware
Please explain

Hi KJ,
Have a look here:
Tristar Diversion
But I could be wrong about that, of course.
On Edit--yup I'm definitely wrong! Rats and Cats and tin foil hats.

Kinda like having 50 amp hook up when you only need 30 amp.

I don't do solar, but it would appear that there is a point that you have more solar input than you have battery capacity. I would think that there should be a matching of solar to battery to the amount of need with a cushion for cloudy days. More panels than that would be a waste.

As a general rule, I use 1 pv watt for each battery amp. Unfortunately, reality is not so simple. Whether you raise your panels or not, summer or winter, heading to Alaska or staying put in Arizona, everybody uses their system differently and you have to adjust your capacity according to that.

My website describes the conversion of my Dodge B-250 van into a small RV. I deal with a lot of woodworking, but hope to be quite specific on solar as well.

The nice thing about having more panels than necesary is that, if one goes down, you will still be charging at a fairly good rate. You would also get some degree of shade tolerance and shade may not be a bad thing, in some situations.

I see no down side if you have the real estate on the roof. We are adding another two 130 watt panels this year for a grand total of about 1120 watts. They are all flat mounted so at best we get about 70 percent of rated output from the panels. We went to a residential fridge this year so the extra capacity will offset the fridge use. We have double the battery capacity you have but 1000 watts of flat mounted panels is not overkill for 4 6 volts.
Being self sufficient for power is kinda cool. Short of air conditioning and using our laundry facilities we dry camp as if we are hooked up to shore power. We have two sine wave inverters that power all the critical circuits.
