Very well built nice design goes well with my other components very happy

We got this 20amp MPPT solar charge Controller to replace the OEM PWM in our 2016 Serenova. The idea was to keep the OEM 200w solar panel on it's own circuit and take the power and dump it on to the bus bars to add to the charging power to the Renogy GO Further 7.6k system with Shadowflux technogy. Separating the two systems kept the Shadowflux panels operating at full effientcy while upgrading the charging potiental for the OEM 200w unit. The connection was simple and we were able to disconnect the OEM converter which freed up a slot in the breaker panel and created additional space under the dinette while simplifying that leg of the charging system. Huge fan. We just tested they enite system with a 4 night get away only using solar power to charge the Renogy 600AH lithium batteries. We were able to utilize Air Conditioner, microwave, induction cooktop, gfi outlets, morning and night without any concern of running out of power. The entire system was a great value and would highly recommend.

It has been working great, we have ordered a larger solar panel to keep the Renogy lithium batteries charged.

Not to hard to set up but need more detail what display messages mean

Everything installed and worked great. Was very easy to setup and the instructions were great. Recommend it for sure.

WRONG mounting screws provided (screw heads way too big to fit into either part of keyhole shape on back of controller!)
Instruction illustration showing wrench tightening that (phillips head) screw essentially IMPOSSIBLE.

So far this little gem seems to be working great. It looks to be well made, and was super easy to install.

I upgraded from a 30A Wanderer PWM to this 40A Rover MPPT after installing a second solar panel on my camper. I'm very impressed. I realize I doubled the panels, but this controller seems to do a better job keeping the battery charged. If was was going to make one gripe, it's the size. The Rover was twice+ the size of the Wanderer and wouldn't fit where I had the Wanderer located.

The new charger looks to be more robust than the one it replaces. The old one developed issues, gettting hot enough at the solar panel connections to melt the box. I do not feel any wamth on the wires going into the charger with the new one.

Battery icons are very small and hard to see, otherwise this is a great unit

Excellent service. Problem solved Thanks

Easy to install. Perfect for my truck.

Great company, great products, fast shipping

Works well. No issues with charging batteries with solar panel.

Pretty impressed. It was easy to set up, easy to use and kept the batteries charged.

Order came in but the main component was missing. Will call tomorrow and see howbthis goes!

When my order came, it was an empty box now I’m dealing with them trying to get a replacement and it seems to be quite a hassle

This solar charge controller works great! I'm under utilizing its capacity but it does the job for me.

Works great and very simple.

I haven't used it. I expect it to perform as well as the others purchased in the past. That's why I bought it. It is stored for a spare if and when it's needed.

I installed the 40i and it is working great. Love the app on my phone so I can keep track of it.

Why would this be shipped without any kind of packing matterial? Just bounding around in a larger box!

Easy to set up and monitor. I’ve had a few in service for over 5 years.

Talked to a young man on the phone and he was so helpful and knowledgeable. Cantbsaw enough about him

great product.

Fantastic customer service and products

High quality unit.

Working great back on track I will be needing two more. Later
