morningstar ts-60 or mppt-60

those of you that are using solar. my question is do any of you know, running max. panels against the controller. is the morningstar mppt 60 worth the added expense compared to the ts-60 ??

What voltage panels will you use with it? Max benefit of the MMPT is with higher voltage panels.

My MPPT Morningstar -60 works great with my 3 Siliken 245 Watt 30 volt , 8 Amp panels, connected in parallel. I have seen as much as 46 amps @14.8 volts going into the batteries in max sunshine and low batteries. I have even seen 8 amps while raining. You won't get this with 18 volt panels and a PWM controller.

Yes, it is worth the money to you use higher voltage panels with a MPPT controller. (In my opinion)

The secret to a good solar installation is:
1. Large diameter wire from the panels to the controller.
2. Mount the controller close to the batteries. (Not in same compartment if wet cell batteries)
3. Large diameter wire from the controller to the batteries.
4. A large battery bank that can handle your needs for at least 2 days.
5. Size your solar for a minimum of 1 Watt for each amp/hour in your battery bank.
(1 1/2 is better)

Follow these key points and you should be happy with your solar installation.

There are a lot of solar panel installations out there and just as many opinions. Others will chime in with their opinions too.

i'm limited to the 18 volt panels. 25 volt panels are to wide. i can get 800 watts of 18 volt. so for this installation would the morningstar mppt 60 be worth the added expense ?? it's my understanding the mppt adjusts output against input and the morningstar ts 60 does not adjust...

Lots of articles and discussion of PWM and MMPT via a Google. With higher voltage panels, seems pretty concusive that MMPT is worthwhile. But not so conclusive with lower voltage panels and RV usage senarios. I got a good deal on 100w panels, so I opted to go with more panels and a PWM TS-60 - therefore I think providing more bang for the buck.

You can use a combination of series and parallel panels to take maximum advantage of the MPPT controller. 2 -18 volt panels with x amps in series = 1 set @36 volts @ x amps. 4 sets in parallel @ 4x amps. The series panels are more susceptible to shading losses than the parallel panels.

Agree - the shading point is why I planned all my panels in parallel.

with all the shading i've got (2 acs, 3 vents, 3 skylights, and vents) i'm going to need to go parallel.

The best thing I bought for my Motorhome was a Trimetic 2025 battery monitor. It cost about $200 with the wiring and shunt. It measures every amp in and out of my battery bank and records the amount, it can be reset daily if needed. It displays the status of my batteries in a % of full number at all times.

With this information, I was able to now exactly how much each appliance draws and what my true daily total consumption was on my battery bank as well as charging amps. It is also piece of mind that my 12 volt system is operating properly. IMO every MH needs one, instead of those idiot lights that come with the MH that only show red, yellow, green battery level.

It help me size my solar installation. Highly recommend you install one prior to your solar install.
