Impressive machine. I was concerned it would be too big for the hull of the boat I put it in, but I was surprised at the size. That's about half the size of a car battery. I'll update this when it's installed. But I really like the remote feature. Very informative. And all at a great price. Update: I've had it installed for a few months now. i love this block Works amazing. The radio switch is great! I like that I can see what's being output on the wireless remote control and turn the inverter on and off. Note: At first I couldn't turn it on or off with the remote control, but after putting the inverter's physical switch in the off position, the remote switch worked fine. I highly recommend this inverter. The only drawback is that the fans are a bit noisy. I installed this in my boat, when the fans spin up under load I can hear it a little.
