Works well. I have it connected to 6KW of solar power and 30 KW of LiFePO4 battery power. It has supplied full power to our house with no issues. It replaced a pair of Growatt 3K all in one inverters that were on rare occasion a bit too small for our power demand. I use a variable speed inverter heat pump HVAC, a heat pump water heater, a microwave, and a heat pump dryer, (gas stove). Through two Hurricane power outages, the lights stayed on, even powered a fridge next door.

I have an older version of this inverter that always had a flicker from the light bulbs. I bought a Meanwell inverter that solved the problem but it died after three years. I bought this one and as far as I can tell there is zero flicker. They must have improved the part that creates the sine wave. The rest of the features have always been good. The setup is important, but once you get it dialed in to your needs, it just works.

utilities of grid charged but inverter no enough for battery capacity (only 12.7v ) then indicated full then cut off charging, please check this and resolve this problem,thank you

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.There is an screen that displays the current mode of operation that is very easy to understand. For example in the picture, you can tell that the power is coming from the grid while the battery is being charged by solar.However, it was really tricky to program because of a very difficult to navigate input system. You have 3 buttons to program 37+ values, and to reach any of those you need to cycle through all the ones preceding.It is the same 2 buttons (Up and Down) to view the different sensors. You have access to many readings, such as battery voltage, output pv power, voltage and amperage, output power, etc, but that also means cycling through 12 displays, including some that are firmware-level (like the fact this is a 24V input, 120V unit). This and the programming above are areas that could be improved.For anyone trying to set it up the same way, here's my settings for a 24V Solar PV system and 24V LiFePo battery pack:* "Load Working Mode" ([01] SOL) : Use Solar first, then battery, then grid* "Battery Charging Mode" ([06] OSO : Only charge the battery with solar power* "Battery Power to Utility Setpoint" ([04] 25.2V) : When the battery drops below this voltage, switch to grid power. For my battery pack, 25.2V is 75%.Important: the manual doesn't specify this, but you must set "Battery Undervoltage Alarm" [14] higher than [04]. If it is lower, the system will simply ignore your setting for [04]. To check, after you set the value, scroll back to [04] and make sure it was applied properly. This really tripped us up initially. You can safely ignore the red "Fault" warning when this alarm is tripped off. We disabled the alarm sound as it's part of normal operation for us.* "Utility to Battery Power Setpoint" ([05] 26V): The opposite of [04]. When the battery exceeds this voltage, switch back to primary operation, in this case use solar first, then battery. For my battery pack, 26.0V is 90%.* "Battery Type" ([08] LF08): Our battery pack matches this setting the closest. Check your battery's manual for the correct values.* "Battery Undervoltage Alarm" ([14] 25.4V): Make sure to set this higher than [04]. The default is only if you want to let the battery fully discharge before switching to grid power.* "Buzzer alarm" ([25] DIS): disable the alarm for low voltage. You definitely want to switch this off if the system is often switching between solar and grid like ours.* "Alarm" ([26] DIS): This will beep when there is a switch from solar to grid or back. We turned it off.
