75 Amp DC Power Output | Replaces all WFCO-8900 | Built-in 4 Stage Smart Charger | Reverse Polarity, Overload and Thermal Protection | Quiet Cooling fan | UL and CUL Approved
I was excited about the PowerMax PM4, but it failed after just a week of use. I followed the instructions carefully, and now I'm left with a broken converter. Not what I was hoping for.

Excellent power converter for RV use!
I use the PowerMax PM4 in my RV, and it’s fantastic! The 75A capacity keeps my batteries charged without breaking a sweat. The quiet cooling fan is a bonus, making it perfect for camping trips.

Easy to install but had shipping delays
The installation process for the PowerMax PM4 was a breeze, which I appreciated. However, it took longer than expected to arrive. It works well once I got it set up, so I’m mostly satisfied with it.

Solid performance but a bit loud
This PowerMax converter has been pretty reliable for my needs. I love the smart battery charger feature, but the cooling fan can get a bit noisy when it runs. Other than that, it handles my equipment without issues.

Great for my solar setup!
I bought the PowerMax PM4 to use with my solar battery system, and it's been doing great work. The 75A output is just what I needed for my 110V AC to 12V DC conversion. The built-in battery charger is a nice touch, too!
