3000W DC 24V Pure Sine Wave Inverter with 80A MPPT Solar Charger and 40A AC Battery Charger, Hybrid Solar Inverter Charger Manufactured by SunGoldPowerCo.,Ltd (Upgraded)

My initial impression of this inverter is great. I have only set it up in my basement for testing and setup. I have not yet connected Solar panels to it. Overall It seems of good quality, sure it's Chinese, but I would not call it junk. Setup and quality seems as good as EG4. This is UL certified and works as I expected it to so far. 5000 Watt inverter is great so far.I got this to setup at my off grid tiny house. I'm just going to use a single All in one, and just 110v. I have 2 48 volt Ecoworthy (budget) server rack batteries, and overall I'm impressed.I will update the review if I have any problems, but the initial setup with AC in and AC out and Batteries was great in my test lab. It's going to provide me a lot more power than what i have today, using Ecoflow (river pro) and a 2nd off brand (1000 watt) solar inverter.When I set this up I went through every setting to make sure it was as desired. I think if you Ground and have a single neutral bond, and proper breakers in the system it will work great for many years.I matched this system with 5 - 460 watt bi-facial SungoldPower solar panels. I won't be setting this system completely up until spring, but Overall I'm pretty happy.

I’ve had this SunGoldPower 5K off-grid inverter running with the SunGoldPower LFP battery and 8-450W panels to supplement my power consumption through a 6 breaker transfer switch. Works great!

This thing is pretty terrible. No way to hook it up to a phone without internet connection, and even then it's dicey. Draws a 5.12kwh battery down within a week - most systems I build are self sufficient and with solar never draw down to zero. This one has a really draw when sitting even though it says it doesn't, wish I could turn the inverter off while letting the solar work (to keep it efficient), but it's only all on or all off. Very clumsy to set up the parameters, and once the batteries are low too low, even with low voltage disconnect set at a higher rate, it will still allow for them to deplete, will absolutely not charge them (even with shore power). Have to plug in a different charger directly to the batteries to get them up to a certain level before this inverter/charger will start working again.

I was assembling a bare cell battery backup system for use in long duration power outages (which I may eventually add some solar to). So, I have it wired to a 305AH 24V LiFePO4 battery pack with a JKBMS. It's been set up basically as a big battery backup system right now, charging from mains, with no solar. It's been working exactly as advertised so far, however, there are a couple of minor negatives using it with LiFePO4 batteries. Its charging settings and monitoring are limited to 0.2 and 0.1V precision respectively. For LiFePO4 batteries where the difference between 40% charged and 60% charged is 0.05V this means it doesn't really have a good picture of the charge-state of the batteries. I had also planned to limit the charger to about 90% of battery capacity, but the charging voltage cutoff precision basically makes this impossible. While the JKBMS can be programmed to cut things off, and I can use it to read out the current charge state more accurately, it's still a slight disappointment not to have more precise controls. Still, the unit is inexpensive, and working as it should, so this is really just a minor complaint.As a separate note, if you need to monitor this system, I was struggling to figure out if any of the available WiFi modules would work with it. In the end I successfully got monitoring working with a RaspberryPi running SolarAssistant connected via USB. Note that the protocol/hardware selection should be SRNE to work with this unit. If I eventually connect solar, I will post again.Do note that if you plan to connect solar that it has a minimum functional solar input voltage of 120V (with an OC max of 450V). This is fine, but it means you'll need a decent number of panels in series to hit the minimum voltage.

Just got this unit and have it wired into a 100 amp breaker box for garage. Have used it for 3 days on just solar charging so far. Have put loads of 1500 watts on it and no issues. Have been testing on my critical loads panel and no issues. I really like the simplicity of these all in ones and the Sungoldpower unit has been a good 1st impression. I will try to do an update in coming months to how the performance of unit is going. My unit is the 24v 3000 watt system

Im brand new to solar, i have slight electrical experience and at first the whole solar system seemed intimidating. But the most flawless part of the system i installed was these inverters. You HAVE to pay attention to specifics like making sure you have equal length battery cables, have them in a properly vented area ect. Ive seen posts on forums of installs where this is disreguarded and the issues are put on the manufacture. This is unfortunate because Since the moment i fired them up they have not skipped a beat and ive put almost 5000kwh through them already. When i had some questions about where to find the download for the monitoring software they were extremely helpful as well. Coming from constant DIY of everything on my homestead and building racecars, i can count on one hand how many times things just worked first try, this was one of them. This is literally the first ever review ive left on amazon, but they deserve it. Thanks sungoldpower!

My use case was for a van build but I realized too late that I would need to put all my solar panels in series to use the MPPT built into this unit, since the voltage required starts at 120V. A previous version had a lower voltage, but I didn't realize they had updated it. I don't want this series PV connection due to issues with shading of the panels and single point of failure. I'll be selling this one and going for the ecoworthy one instead. Otherwise it seems like a reasonably solid all-in-one, though I paid 20% more than the current price, for something that isn't ideal for me.

Works just like advertised. Clear and concise installation instructions including wire and breaker sizes.
