30-Amp Bluetooth solar controller with PWM technology regulates solar panel output to provide consistent amperage to your RV batteries. Protects battery from harmful overcharging and uses automatic multistage charging to extend battery life.
Features:
Specs:
This solar controller prevents harmful overcharging by adjusting the power generated by a solar panel before it reaches your RV batteries. It uses pulse width modulation technology to regulate the output through pulses that provide a consistent charge. Typically, this type of technology is a good fit for smaller systems with lower voltages.
Using a multistage charging system, the controller automatically switches voltages while the battery bank charges. This accelerates the charge, but also helps extend battery life by adjusting the voltage during the different modes. The controller is compatible with multiple battery types and includes preset charging profiles for sealed/gel, AGM, flooded/wet cell, and lithium batteries.
With Maximum Power Boost Technology, you can simply press a button to activate Bulk mode for the highest charging voltage. This lets you quickly top off your battery bank before the end of the day by capturing as much power as possible.
This solar controller is built to charge 1 battery bank and has terminals for only a single battery.
The backlit, digital display acts as an information center for your solar panel output. It shows the charging current, battery voltage, and battery state of charge. It also allows you to input your battery type and choose a charging profile.
It includes a Bluetooth function that lets you connect the controller to your smartphone or tablet with the free Go Power! Connect app. With this app, you can wirelessly view the same live battery information included on the display. Also, you can control your battery profile and toggle Maximum Power Boost Technology mode.
Lastly, the controller includes several built-in safety features to help protect your equipment. The charging process will shut down if the controller starts to overheat and when an overcurrent is detected. Also, if the battery or solar panel is wired incorrectly, it activates a reverse polarity alarm.
By linking the solar controller and a Go Power 12V pure sine wave inverter with a typical telephone cable, you can control the inverter's power function. Additionally, when the battery bank falls below 11V, the controller uses an automatic low voltage disconnect that shuts down the inverter. After the bank has been sufficiently charged (12.8V for lead acid and 12.2V for lithium), the inverter will turn back on automatically.
The solar controller flush-mounts to a wall inside your RV. It is wired to the solar panel using MC4 cables. Then, the battery bank is wired to the primary terminals on the controller. If you are using additional batteries, they can be connected to the secondary terminals. You can also install a fuse or circuit breaker (sold separately) up to 50 amps between the solar controller and battery for additional current protection.

Great service and friendly return
I think this is one of the best companies that I have dealt with. I recently received a damaged solar panel, called them and they immediately resolved the problem and later that same night I noticed they had already shipped out a new one.
The customer service is THE BEST!!
Highly recommended
Thank you
Works well, had some issues with a connection and called support @ GoPower. They were very helpful and we’re up and running. Customer service was awesome. We are now getting maximum solar. Very happy!
works great, still running strong after a year
Very fast delivery
Bluetooth function not working properly. Not enough YouTube nor instructions from manufacturer to get controller to work properly as advertised. Controller is managing solar panel to charge batteries and hold charge but all other functions do not appear to be available. When I do end up replacing this replacement I will go with a more expensive option from a different manufacturer.
Thank you for the quick delivery AND.. the excellent communication in helping me understand what I needed and how to put it together. Great online vids helped!!

Hey Richard! Solar can get confusing sometimes so I am glad that we were able to help you in your journey with it.
Just got it hooked up, works very well. The Bluetooth feature is a game changer. I can check on it through my phone.
This works perfectly. Delivery was very fast. I replaced my old AGM batteries with lithium batteries and changed the solar charger control module to this new one. Very easy installation.
Install easily and is working as advert ised.

Has worked flawlessly in its year of operation.
Works easy setup
Works well. Good upgrade.
This controller works well very easy to install
Need manual not sure if it’s working co rrect
Easy upgrade to enable lithium charging profile.
The Go Power 30 amp PWM solar charge controller has been installed. Works great! And the shopping and customer service experience with etrailer.com was also great. Thank you all!

Yay, we're happy to help everything come together smoothly for you, Peter! Keep shining :)
Works great and the app hooked right up. A great way to monitor battery usage!
Other than the out of stock deliver was quick
The replacement has a different footprint so has resulted in some fill in to fill the gaps.
Nothing we can’t overcome.
Upgrading from 10 amp controller to 30 amp due to additional panels. This controller was in stock, priced well and same Go Power brand as old 10 amp. Shipped quickly, arrived as scheduled. Installed and working great. eTrailer is a great source of parts for trailers and RV.
It needs directions with it. Everything is guess work.
so far so good. It’s working
Got it today! Already looked through the videos and will be installing soon. Replacing an older Go Power controller - hope it will fit the same hole.
I have 2 controllers each with a 125 watt solar pannel. Keeping a single winch battery in a trailer and a 2 battery rv topped up. The controllers have served my purpose perfectly. Everything is ready to go when I need it.
Great to work with fast shipping
While I have not yet installed this controller, I had the same one in a different RV and it worked well. It definitely does what’s it designed for. This a great controller for a small capacity solar setup. The Bluetooth function also works well.

After one year, the controller still works great. I’ve added another solar panel to provide more amps for charging my lithium battery.

This all sounds really frustrating, and I’m truly sorry you’re experiencing this. I reached out to the manufacturer for some troubleshooting guidance, and they mentioned that both Bluetooth and location services need to be enabled for the system to work properly. They also suggested trying a fresh start, uninstalling the app and setting it up again from scratch. It’s not ideal, but it might help resolve the issue. Let me know if you run into any other issues.
