PowMr Solar Inverter 3200W 24VDC to 110VAC, 3.2KW Pure Sine Wave Inverter Bulit-in 60A MPPT Controller and with 40A AC Charger, Max.PV Input 1600W 108V, fit for Lead-Acid and Lithium Battery

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.

I liked that everything was straight forward and easy to install. The Mr Power 5000 Watt 48 Volt Hybrid Inverter works perfectly! I have (10)400 watt solar panels feeding a 48 volt battery system. The Built-In charge controller automatically switches from battery charging to sending excess solar electricity to my house and then back feed the grid. Works Flawlessly! Highly Recommended!

Of course I wanted this to work and it did for 1 week. Then it became unstable and started doing crazy things and I spent hours and hours trying to figure out what setting might be wrong. I paid to have my installation checked by a licensed electrician and was given the thumbs up. I spent days emailing with tech support and they were responsive but not helpful, One day between each email due to the time difference. I tried everything I was asked to do and nothing helped. I have since returned the inverter and installed a different inverter. I used the same settings for the new inverter and it has been perfect since day one. I have not had to change any settngs since I installed it and it has been flawless. I see some folks have good luck with this inverter but I have not and the manufacturer wants to put the blame on the end user. Good luck if you purchase this device as maybe you will get a good one or you might have my same experience.

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.Second its basically perfect for a boat or small house solar. The 3k inverter is enough to run a 1500 watt heat gun and still run my tv and fridge. I use lifepo4 batteries and charge up to 5kw at a time, this charger will charge up to a little more than a kWh ber hour from utility power. I also use a pigtail to charge from a generator through my shore power connection. Your charging from solar will depend on your output of course. Unit is quiet at low to moderate loads and even with the fans on it not very loud.The LCD is easy to read and understand. LEDs are easy to see, and the included book includes all the register values and defaults. You'll probably only need to change two to four of the values, like battery type and charging behavior.The WiFi dongle is completely useless. Basically it showed me the product information printed on the unit. I was never able to even see live data much historical data.If you want a system for a boat that is zero hassle once you set it up and run or have 24 v battery pack then this is a great choice, I couldnt be more pleased.

Installed our home system 3 years ago before the all-in-one units were heavily on the scene. Everything you see in this photo is now inside this one neat case. Purchased this about 10 months ago for our homebuilt camper. It has been rock solid and been running 24/7 since install the beginning of the year. Running fridge, AC, heater, lights, TV, water pump and cook top. Absolutely love the unit and it's features. Wish I had used this on our home system but either I missed or they were not out at the time. There is a learning curve as there are so many options and features. The manual is pretty good but also missing a few things. However, Y-solar jas been great and timely in answering questions and giving support. I've purchased all my units for home and camper from them and they've always been very helpful!
