Preface: I'm using this in a boat which is acceptable but not ideal. It has to do with the way the neutral and ground are connected. However, this is more of an issue with combo interval/charger units, and since this is strictly an inverter that gets turned off when we're finished with it, that makes it acceptable. Please consult a qualified marine electrician. Product evaluation: We are very happy with this inverter. The instructions are clear and it works as described. We have purposely purchased appliances that are lower wattage so that it can run 2-3 of them at once. As a test, I used it to heat a tank of water on the boat and it did the job. If the batteries dip below about 11.5 volts, it will keep working but start beeping. As you may know, flooded batteries (which we have) can drop down to 11.5 volts for a short period without harming them. Once the load is taken off, they generally "recover" to well over 12 volts. While the inverter comes with a wired remote on-off switch, we do not use it. As should always be installed, we have a rotary inverter power cut-off switch between the battery bank and the inverter. We simply leave the power switch on the inverter housing in the on position, then use the rotary switch to turn it on and off. We also installed a 250amp fuse between the battery and the rotory switch. Do not use the inverter without a proper fuse. The inverter comes with 2 battery cables but they were not adequate gauge for our application. There are tables online that will tell you for a given load and length of wire run what gauge you need. Do not gloss over these details. The wires being included could lead you to believe they are all that's needed to connect the inverter to the battery, but that would leave out the fuse and cut-off switch. We have now been using the inverter for a couple of months with zero issues. Because we have it installed where we can't easily see it, we like the short beep that it makes when we power it up. It gives a similar but longer beep when powered down. No negatives to report.

I purchased 2 of these Heavy 18lb Extremely Powerful Pure Sine Wave Inverters, because all independent tests confirmed they exceeded expectations across the entire scale. Thank you for supporting America and it's Armed Forces!!

This inverter is perfect for my off-grid RV setup. The ATS is fast (20ms) and switching from shore/generator to battery power is truly seamless.The challenge for me was avoiding an electrical loop. If I charge batteries from the AC to DC converter (built into the AC breaker panel) then there would be a problem as the batteries are sending power to the inverter which is sending AC to the converter, which is sending DC back to the batteries (bad).So to solve this I moved the AC to DC converter to the circuit BEFORE the AC input to the inverter (added junction box and breaker). This way, the only time that AC is providing power to the DC converter is when on shore power (or generator).All is working flawlessly and automatically.Note: I appreciate the technical support from Renogy and have updated them with my solution for this safety issue.

This is an absolute monster of an inverter, I was able to wire a 30amp RV pug directly into the high output, works amazingly, even runs the AC no problem, highly recommend, uses very little wattage in idle mode. Bluetooth makes for easy monitoring, the Renogy app is free and you can set it to track your daily usage for realtime data. Very cool
