Morningstar TriStar TS-45 45A PWM Charge Controller

I actually bought two of those: one is a charger and one is a load control. Not that expensive actually! These controllers are so simple, I barely looked at the manual.

Morningstar Charge Controller ProStar PS-MPPT-40M 40A MPPT

I’d give it the highest score overall, but it took me a while to get used to the menu and display. There were a bit too many options for me, so be ready to keep the manual close at hand

Morningstar TriStar TS-45 45A PWM Charge Controller

The controller is absolutely fine. It is a good price and it does well. at least my battery doesn’t get overcharged like it used to, so i hope this one will last longer than my last.

Morningstar Charge Controller ProStar PS-MPPT-25M 25A MPPT

It’s a piece of engineering art. Besides, Morningstar is known for their great tech support, so should anything happen they will promptly respond and take measures. A1Solar has also been a great partner so far

A very solid device packed with features for tracking performance. I had a few display freezes in the beginning, but after a firmware update I’m 100% satisfied with the device

Morningstar Charge Controller ProStar PS-MPPT-40M 40A MPPT

I bought it for a 900W PV system and it turned out to be a great match. I can recommend the device for arrays of similar size.

Morningstar Charge Controller 20А SS20L-12V

Very easy to install + flawless performance. there’s no digital read-out, but I don't have time to stare at it anyway. I use a multimeter to check it every now and then and it is ideal every single time

Morningstar 10A-12V Charge Controller SS10L-12V

I ordered one of those cheap Chinese controllers a few months back. Wanted to save a few bucks. That was a mistake. What they sent me looked like a piece of junk. The instructions were missing. To get a better CC I did a little research and came upon the A1 SolarStore. The delivery time and service were excellent!

MORNINGSTAR Charge Controller MPPT 60A Battery TS-MPPT-60

One of the best MPPT controllers on the market! For me, the best part is the manufacturer. It is a reputable company dedicated to solar instead of a huge corporation that makes all kinds of stuff.

I think this one will outlive the boat. The little 20a was still working fine after 14 years, just upgrading my system. I will keep the 20 as a spare.

Morningstar is unbeatable in quality and speed of installation! PS 15 is exactly what I needed for my solar fridge! My order was handled professionally and the delivery was fast

Morningstar Charge Controller 20А SS20L-12V

I purchased 4 inexpensive solar charge controllers in the past. None of them lasted beyond five or six months. I decided to spend more hoping for a longer lifespan, and I am very happy I did!

MORNINGSTAR Charge Controller MPPT 60A Battery TS-MPPT-60

The installation went without a hitch. The previous one burned up due to rats shorting it out. But it worked flawlessly for the past 7 years. Very satisfied with this controller and with the store

Morningstar 10A-12V Charge Controller SS10L-12V

My garden is too far away from the house and there is no electricity. I wanted to construct an electric fence and install the pump to bring the water in. So I decided to make my own little solar farm. This charger was perfect for my use.

Morningstar Charge Controllers ProStar PS-30 Gen3 PWM

Very satisfied with the ProStar 30 Controller. Simple set up and design, well built to survive life on a boat. Just need to upgrade my solar panels. Can recommend this device to fellow sailors. The interaction with the shop’s team was very smooth

Morningstar Charge Controllers ProStar PS-15M Gen3 PWM

I ordered this unit for my trailer to charge 3 deep cycle batteries. So far no complaints, works as a charm. Mine is the model with a display, it shows the actual system voltage. I can see it from across the room in the dark. That's a very nice feature, so I recommend the ones with a display

Morningstar Charge Controllers ProStar PS-15 Gen3 PWM

The Prostar 15 is a no-nonsense charge controller for good money. I have been using mine for a few days with a 100w solar array. I installed it in a matter of minutes on my boat. It gives off no noise or interference (I mounted it a couple feet away from my radios). There are many other chargers out there, but for the intended application, the Prostar is a solid choice at a great price.

Morningstar Charge Controller 20А SS20L-12V

I got the Morningstar SunSaver because I wanted a controller that had a more industrial design and was easy to read at a glance. The other controllers I have seen seemed inadequate or low-quality.

Morningstar Charge Controllers ProStar PS-15M Gen3 PWM

I’m very pleased with the performance, it is a great controller. The hookup couldn’t be easier. The LCD displays correct values for Solar Current, Battery Voltage, and Load Current. Handles all types of batteries. Charging modes include Boost, PWM Regulation, Equalize, and Float. Highly recommend the store and the product

I have been using the same controller the past seven months for solar landscape lighting. Very reliable, I’ve had zero trouble. I have negative experiences with cheaper devices, so for me this model is well worth the money

I've never had any trouble with prostar chargers. I bought this controller for my RV, keeps the batteries in excellent shape. Definitely recommend the brand and this store

Morningstar Charge Controllers ProStar PS-30M Gen3 PWM

My first purchase was a charge controller for a little over 50 bucks. It was money wasted. If you're just starting out with a basic PV system, I definitely advise spending the extra dollars to get a controller like this one. The display makes it easy to detect any problems. Great product and amazing service!

Morningstar Charge Controllers ProStar PS-30 Gen3 PWM

Works awesome! I had been using the Prostar 15 for years at a solar powered radio site. Not a single flaw in all these years. There was a need for upgrade, so ProStar 30 was my obvious choice. For those who wanna use this controller for a 2 way radio, rest assured it does not generate any interference

If I exceed Nominal Max. Operating Power, it won’t harm the controller, right?

A1 SolarStore

Yes, this will not harm the controller given Open Circuit Voltage is not exceeded.

Is it a good option for a boat?

A1 SolarStore

The device has a conformal coating and marine rated terminals, which makes it suitable for use on a boat.
