We have been in the inverter field for more than 10 years, and we aim to provide high quality inverters and good service to every customer! If you're trying to build solar system for your RV and off-grid home, we are your best choice !
5000 watt DC 48 volt solar inverter’s conversion time between bypass and inverter is 10ms; Rated input voltage 110/120Vac, Frequency 50Hz/ 60Hz (Auto detection); Efficiency >95%(AC mode), Efficiency >92%(Inverter mode), PV voltage range 120-450Vdc, PV maximum output power 5000W.
4 Charging Modes
Only Solar Charging: The battery will be the only charger source not matter the utility is available or not.
PV Priority: Solar energy will charge battery as first priority. The utility will charge the battery when solar energy is not available.
Utility Priority: The utility will charge the battery preferentially, and the battery will be charged by solar only when the utility is invalid.
Hybrid Charging: The solar energy will charge the battery preferentially, the utility will charge the battery at the same time when the solar energy is insufficient.
Parallel Support and Wirings
When inverters are used in parallel , it should be noted that:
- 1. Each inverter should connect to PV modules separately.
- 2. The settings of each inverter should be the consistent.
- 3. The input connection of each inverter should be the same.
- 4. Be sure to connect Current Sharing cable to units which are on the same phase. But please DO NOT connect Current Sharing cable between units on different phases. Otherwise, it may damage the inverters.
- 5. Be sure the length of all battery cables need to be the same, and share the same battery bank.
- 6. Please use the original Parallel Cable and Current Sharing cable. Do not make them by yourself. And Parallel cable and Current Sharing cable can not be parallel with the AC power wires and battery wires, need to cross or interval 1 meter distance between them.

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.

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

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.

Working fantastic, worth every penny.

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.

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.

I have used mine for over a year with no problems. I did buy 5 more inverter that were Ata later revision of software, so I needed to update the older one I had bought . The support@sungoldpower.com was great, they got back to me very fast, and gave me simple and correct information on doing a software upgrade. Now all inverters are working together with the latest software and features. No cost for the support. I use the system hard and it seems solid.
