Power Queen 12/24V 30 Amp MPPT Solar Charge Controller with Built-in Bluetooth, Support Remote Monitoring, Default for LiFePO4 Batteries and Compatible with Sealed, Flooded, Gel and Lead-Acid Battery

it is powering my single 100 AH LiFePO4 battery, which runs my 120 volt, 7 cu ft chest freezer, via a 600 watt pure sign wave inverter, and my 12 volt 55 quart chest refrigerator. I have 300 watts of soloar panels feeding this unit. it has been running flawlessly for 2 weeks. i am, so far, very satisfied with this controller.

I had a question and Power Queen customer service quickly responded. Thank you Yuki. So far i couldn't be more pleased with the product and customer service. Yuki, requested to know what panels I was using to make sure my solar panels were compatible, they are. Good to know, being a first timer like I am, as a solar power producer. My system is a somewhat larger system than I will normally need, but in the winter months, here in the Pacific North West the sun is very low in the sky. At the time of this post we may have had 3 hrs of direct sun light in the past 2 weeks with only a 9% power loss due to the controler and. So I have a Power Queen 30 amp charge controller to 8 -100 amp hour lithium iron phosphate batterys wired in series then parallel for a 24 volt system. Wired to 8 - 100 watt, 24 volt panels, giving me over 10,000 watt back up power WHEN, not if our power goes out. It keeps my chest freezer, small refrigerator, Ryobi battery chargers, and internet/security system online. Also I'm hooking up my garage door opener which is a annoying when you got to go and have to manually release the door from the operator to open the door.

Excellent . Love the Bluetooth

It works, it has it's own app, and it was affordable. I will update this review if anything changes. Customer service is very very very talkative...*The more I try and use this MPPT, the worse it gets. The APP cannot stay connected from 5ft away. Sometimes the APP connects, and doesn't display anything. Sometimes the APP connects, and DISPLAYS THE WRONG DATA! Not sure who the actual manufacturer is (this unit is identical to the LiTime model) but it is not great at all.*The app and connectivity issue are too much to deal with. Even 1 foot away its hit or miss, meanwhile I can see 2 bars on my neighbors TV.. Leaving it at 3 stars, as it does it's job, but the Bluetooth and or app are pretty bad. That said, the Load feature is REALLY good, the display is useful, and if they made a 50a 60a or 100a version, I would be on board, but charging 4000wh at 12v 30a takes a very long time...

Works well. Like it should. Incredible support.

It works as it should, easy to install, and user friendly interface. No complaints.

Working fine for a month now. Decent charge current. Had to use the user settings to charge best for LiFePO4 batteries.
