Works well. Have evaluated and tested most features with oscilloscope, power analyzers, and bench testing. Internal battery current indication is off by 2%, but within expectations. Conversion efficiencies are well above 90%, fans turn off or down during low power usage. Thermal management good, has internal air ducting to force air to selected parts of the circuitry. Self-protects against overpower, shuts down if necessary. MPPT functions well. Overall: well worth the price for a medium sized application. I am a retired power conversion engineer and was looking for a cost effective, reliable system. It more than met my expectations so far. Will update if I have future reliability issues.

First if you have the slighest experience with wiring or electronics you could install this without the instructions because all the ports and internal connection points are labeled. If you dont have experience the large sheet color instructions are clear and easy to follow.

Using this hybrid inverter as part of a backup system for when our utility shuts the power off, and it has performed very well. To get some ROI on the investment, we wanted it to power some appliances during the day and especially during 5-8 pm when our rates are the highest, and switch back to grid power when the battery dropped below 75% so that we have some backup for lights and electronics if we needed it. We were able to set it up to do just that, hence the 5 stars.
