Get overall more efficient power production with MPPT

The Morningstar MPPT Controllers have the industry’s HIGHEST peak efficiency of 99% and significantly less power loss compared to other MPPT controllers. You won't find any other controller with production OUTPUT efficiency this high. Unfortunately, most brands are only 93-97% efficient. Still sounds pretty high right? (Wrong)
Is just 1% a huge deal? YES! The power loss from heat is 100 % GREATER at 98% compared to 99%. That's right, ONE HUNDRED PERCENT! TWICE AS MUCH VOLTAGE LOSS for each ONE percent in efficiency! (read that again if you're thinking of getting another brand of MPPT besides Morningstar)

 

HIGHEST RELIABILITY IN THE INDUSTRY

Your charge controller provides Core System Functionality

Morningstar has been making charge controllers for over 25 years and there are over 2.5 million off grid installations operating in over 122 countries. Guess what? MANY of these controllers have been running constantly since the early 1990's and are still function perfectly. I've sold 1000's and never heard from a customer of a failure. Ever. They actually advertise a "15 year expected life". Importantly, you need to remember that a failed / faulty controller means TOTAL SYSTEM FAILURE, and possibly a fried battery bank.

 

 

 

More power harvest in low light & low temp conditions with MPPT

Hence, more power when you need it most. (Ever heard the word "BOOST" used by marketers to sell lower quality MPPT controllers? Morningstar INVENTED it)

 

 

 - Get more power early and late in the day, and cloudy, hazy or shady conditions
- Similarly, in cold winter weather solar panel voltages get much higher, but days are shorter, MPPT takes advantage of it
- With deeply discharged (dead) batteries. MPPT will send much higher current to your batteries as needed to recover quickly

 

You can use larger high voltage solar panels to charge 12v batteries

And 2 x 12v panels can be connected in series pos to neg for a 24v system

(MPPT can be set for 12-24 or 48 volt battery charging systems)

-higher voltage is converted into more amps going into the batteries with MPPT
-Smaller wire can be used in long wire runs to avoid voltage loss with 24v or 48v systems. (12v panels can also be wired in series for higher voltage)

 

 

 

Can Morningstar Solar Charge Controllers Charge Lithium Ion Batteries?

There have been a number of questions recently about whether Morningstar solar charge controllers can be used to charge lithium ion batteries in off-grid solar applications.  Morningstar’s TriStar MPPT, TriStar (PWM), ProStar MPPT, ProStar (Gen3), SunSaver MPPT, and SunSaver DUO solar charge controllers support Lithium Ion (Li-Ion) and other battery technologies such as:
  • Lead Acid (PbSO4): Sealed (VRLA, AGM, Gel) and Flooded
  • Lithium-Ion (Li-Ion or LIB)
    • Lithium Iron Phosphate (“LFP”, LiFePO4)
    • Lithium Iron Magnesium Phosphate (LiFeMgPO4)
    • Lithium Manganese Oxide (“LMO”, LiMn2O4)
    • Lithium Nickel Manganese Cobalt Oxide (“NMC”, LiNixMnyCozO2)
  • Nickel–Cadmium (NiCd or NiCad)
  • Nickel–Metal Hydride (NiMH or Ni–MH)
  • Nickel–Iron (NiFe)
  • Nickel–Zinc (NiZn)
  • Aqueous Hybrid Ion (Aquion or AHI™)
  • Flow or Redox Flow Battery
    • Vanadium Redox (VRB)
    • Zinc–Bromine (ZnBr2)
    • Zinc–Cerium (Zn-Ce)
All of the above-mentioned Morningstar controllers offer custom programming to create pre-configured plug and play settings that can be tailored for most types of batteries.  For more information, please go to our Best Practices By Battery Chemistry page.

 

 

Long Term Dependability

We want you to have a system that actually works well and lasts for years, but here's the

#1 THING YOU NEED TO KNOW

ready for the answer? (what many don't want you to know)

Your RV Solar panel system is only as good as the charge controller

It's the heart of your system and all controllers are far from equal.

Amperage and voltage ratings differ, but more importantly, charging algorithms, protections and advanced features vary greatly between brands. Maybe that's why there's a HUGE difference in the warranties!

Are the “cheap” kits really saving you money?

Besides complete system failure when a controller goes bad, the chronic undercharging of your expensive batteries will cause them to fail and need replacement much sooner. Morningstar is an American company and has had over 2 million controllers installed in 111 countries over 20+ years. MANY are still in operation today

 

 

 

SS-20L-12V

Can a standard PWM controller make more sense?

There's a difference between using solar for off grid weekend camping and trying to live full time off battery power and on a budget. When do I tell folks they DON'T need a more expensive MPPT controller? (I actually live off grid with our products and have years of real life experience. I know what works or not and we never try to sell you something you don't need)

 

- If you have a small system with only one or two 12v panels, the extra boost might not justify the added cost of MPPT if you can simply add another small panel
- If you have a medium to large system with 3-4 panels, you never drain your batteries below 50% and your location has long, warm and sunny days without shade? You probably don't need MPPT
- If you want a 24v system with 24v panels (or 2 x 12v in series) there are 24v versions of PWM  controllers
- In order to use high voltage 60 cell panels, You MUST use MPPT.  PWM won't work.

 

If your system size is limited by roof space for only 2-3 panels and you want to squeeze out every drop of power you can? (and even be able to recover "dead" batteries) MPPT is the obvious answer.
With a system larger than 4-500 Watts? It's almost always worth it to use a Morningstar MPPT
