Renogy Inverter PUH 3000W, 12V to 110V Pure Sine Wave Power Inverter, Built-in Transfer Switch and Bluetooth, DC to AC Solar Converter for RV, Truck, Camping, Home, Emergency, Off-Grid Living

When the on/off is in OFF no grid power is passing through the inverter. I do not want to leave the inverter ON 24/7 because my RV is often parked at home for 2 months. If I turn the inverter OFF there would be no power in the Rv. Very little is expected in the directions on the operation of the inverter.

Works as described

If your buying this for it’s Bluetooth functionality-don’t! You can only view a few parameters, no ability to control the device. It cycles on and off continuously, even when connected to shore power. Opened the app to turn it off because it kept waking us up - not an option. Tech support is a joke, type a question get a prepared answer that isn’t an answer. An owners manual that explains the function of the device would have been a nice touch. Very disappointed.

Put this one in a semi truck. Works really quite . Easy to install and plug into trucks electrical system Has a remote display to monitor voltage.

This is good, well built inverter. BUT, and this is a big consideration, it must be ON for the transfer switch to work. This wouldn't be such a big deal, but when it is on, you cannot tell if the load is coming from grid or the inverter, there is no way to tell, other than thru the blue tooth app. The cooling fans cycle, even when on grid power, or when the load is light, so be prepared for some noise. Otherwise it powers A/C microwave, etc just perfectly.

Ok, works fine and the built-in ATS is convenient; but there are a few negatives to this device that make it make more sense to just buy a separate ATS and inverter without it built-in. - The N-G bond relay is slower than an external GFCI device will trip; that means it will cause you to trip an external GFCI outlet that you plug into. You have to disconnect the N-G with the switch; but remember to turn it back on when using the inverter!!! - The inverter overload protection at 2000W applies to non-inverter loads! If you're using the ATS, it can't handle more than 2000W. So, either get the 3000W version or just use an external ATS if you'll run more loads when connected to shore power. - The passthrough doesn't work when the inverter is off. This is really quite annoying.

This runs my appliances cleanly without weird noise, flicker, or “something feels off” behavior. The Bluetooth monitoring is actually useful (not just a checkbox feature), and the install is straightforward as long as you plan your cable routing and fusing first. Feels like a legit upgrade.

Powers my residential refrigerator in my motorhome. Works as hoped for.
