The build quality is solid, pure sine wave output works perfectly with sensitive electronics, and the UL1741 certification provides great peace of mind. Easy to set up, quiet, and highly efficient. Very satisfied with this purchase—highly recommended.

To be clear, I am not a PV electrician. However, I am a fearless DIY guy when it comes to saving money to improve my home. After weeks of research and consideration, I recently made the switch to the SUNGOLDPOWER UL1741 8000W DC 48V SPH8048P Hybrid Solar Inverter, and I couldn’t be more thrilled with my decision. This inverter not only rivals others in the market but does so at an incredibly competitive price point—often at half or even a third of the cost of comparable models like the Fronius and EG4.From the moment I unboxed the SPH8048P, I was impressed by its design and build quality. The installation process was straightforward. The inverter features screw-down terminals for AC In, AC Out, PV1, and PV2, which made wiring a breeze. Within a few hours, I had everything set up and ready to go, thanks to the clear instructions provided.One of the standout features of the SPH8048P is its efficiency in feeding excess power back to the grid. After replacing my previous Fronius IG Plus Grid Tied inverter, I noticed a remarkable 20% increase in the power being returned to the grid. This performance is not just impressive; it also positively impacts my energy bills. The inverter efficiently handles and optimizes solar energy, making it a smart investment for anyone looking to reduce energy costs.This inverter shines with its AC Out function, providing a seamless transfer of power to my transfer switches during battery backup scenarios. It has made my system more reliable and reassuring, knowing that I have a solid backup in case of power outages. The transition is smooth, and I have had zero concerns since installation, which has significantly improved my peace of mind.The SPH8048P also comes equipped with smart charging parameters that expertly manage the charging and discharging of my 15KW 48V LifePO batteries. This not only enhances longevity but ensures that my batteries remain in peak condition, maximizing their lifespan and efficiency. It’s comforting to know that I have an inverter that actively works to protect my investment in battery technology.A special shout-out to SUNGOLDPOWER's customer service, which exceeded my expectations during the DIY setup. I had several questions regarding parameter settings and received prompt, knowledgeable responses that helped facilitate a smooth installation. Their dedication to customer satisfaction certainly adds to the overall value of this product.In conclusion, the SUNGOLDPOWER UL1741 8000W DC 48V SPH8048P Hybrid Solar Inverter is an outstanding choice for anyone looking to harness solar energy. With its combination of superior performance, ease of installation, excellent battery management, and exemplary customer support, I genuinely feel like I’ve made a wise investment. If you're considering an inverter, look no further—this one is truly a game-changer! 5 Big Stars

I am using this inverter inline as a battery backup with my utility grid; no PV, and not off-grid. This inverter seems to be using power from my batteries, and because of that it is constantly cycling from drawing battery power and charging, mostly constant charging, even when this feature is OFF. Its not drawing power and supplying out, it's just consuming and recharging, forever. Thats just extra consumption I'll see on my utility bill. Number 2 is the web app, or lack thereof. The manual just says "easily control through the app" but not what app. The app I found that works (solarman pro) doesn't allow any control, only monitoring and its not the greatest to access that information. Fourth would be the terminals for AC, could be better and larger (#6AWG barely fits). Two stars because it's fairly well built, easy to use and UL listed and WHEN doing what its supposed to (DC to AC inverter) it does well, fast, and quiet enough for the price. It seems to not care now if I disconnect the batteries, it just alarms low DC voltage, continues to try and charge, while acting as a pass though from grid to house. Even if that seems dangerous, im ok with it as it allows maintenance on my battery side without losing power to the circuits its backing up.

This 48vdc -10,000 watt 240vac inverter has been making clean steady power without any problems at all. Even runs my 5 hp 80 gallon tank air compressor just fine. Along with air conditioning, freezers and fridges. It’s very quiet but slight sounds can be heard from the fans when it heats up for a few minutes. Then back quiet again. When grid power goes out I’ll have no problem because this will keep everything running without gasoline generators. Also it switches to inverter power anytime the grid goes down without me doing anything. Solar panels will keep battery charged in daylight ( as soon as I get them installed ) so night and day I’ll still have everything running. If power is off for days it really doesn’t matter. Plus I’m saving a lot of money on my electric bill now. Inverter/ with batteries in the day and grid and charge batteries at night. ( My electric plan has free electricity at night ).This is the only inverter I’ve found that will allow you to set when it charges your batteries from the grid, and when you want it to go from grid power to inverter/battery power. Several times a day if you want. Then when you want it back to grid power. Or just stay on inverter power all the time. I charge batteries at night when grid power is free on my plan. Then go to inverter/batteries in the day. It has a huge amount of options ( 68 ) to do exactly what you want it to do. You also can add up to 10,000 watts of solar power into it ( has two MPPT’s ; up to 500 vdc ) along with the grid, and batteries, or any combination You can set how much current to charge the batteries from the grid up to 200 amps.Take your time and think what is best for your system and if it’s not how you want, then change the settings until it is. Not hard at all. I absolutely will be adding more of these 10,000 watt inverters, up to 6 total I think it says, as soon as I get more batteries.When this inverter switches, automatically, you set how you want it, to the grid or from grid to inverter/battery power, you will never notice it happens. No flicker or flash and doesn’t cause things to be reset like some do. Tv never flickers or blinks. It is clean, pure electricity. Maybe better than the grid? The price is unbeatable. Compare this to other big brands and this unit beats them all. The company has been around a long time with great products. Well worth the money…. Buy these.I’m not selling these. Just excited to finally get an inverter that really does work well how I want, not how they say I need.

This is a very nice inverter. Works exactly as it's supposed to. I really appreciate that I'm able to have two different solar arrays come in and power the unit. Furthermore on a sunny day I can easily charge my 30 kilowatt battery Bank in less than 3 hours.
