SUNGOLDPOWER 10000W DC 48V UL1741 Solar Inverter,Support Parallel, Built-in 2 MPPT Solar Controllers, Max. 200A Battery Charging, AC Input/Output 120V/240V(settable) Inverter Charger(10000W DC 48V)

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

Excellent inverter, very powerful and reliable. The SUNGOLDPOWER 10000W DC 48V UL1741 delivers stable performance even under heavy loads, making it ideal for residential or small commercial solar systems. 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.

This inverter is an amazing product, especially for the price. I use it with about 8500w of solar, used Tesla battery modules, 240v grid input. Since my electric provider doesn't pay as much for the power I give them as they charge for the power I buy, I use the inverter in Solar/battery/grid mode. This means everyday I'm charging my batteries with the excess Solar, and every night I discharge the batteries. I set my max amp rate to 150 amps, and the inverter has no problem handling it and maintains temps well. I will soon up that to 175 amps as more batteries are used. The switching between battery and grid after I've discharged my batteries is seamless, and the only way I notice is from the beep on the inverter. About half my house is on this inverter, and none of the electronics lose power during the switch. The 2 mppt's make it easy to wire panels from different sides of the roof. Great product, will be buying a second one soon to up my power to 20kw!!

Has been working nonstop for a year without any issues in SUB mode. Using 12 12 volt AGM batteries in series. Each group of 4 batteries is 48 volts/100 amps and they are all connected in parallel to the inverter, for a total of 14,400 watts/48 volts/300 amps. Connected to 10 320 watt bifacial solar panels, for a total of 3200 watts in MPPT controller 1. Make sure to read the manual and set everything accordingly. Most people think it is a set it and forget it inverter and it is not. You need to configure the current from grid, generator and batteries, taking into consideration that grid is 120/240 volts and batteries are 48 volts. Pay special attention to battery settings such as type, float, cutoff, etc; otherwise you may damage them or reduce lifespan. When power is out and there is little to no sunlight I use a gas generator as grid input to charge the batteries and provide power to the home while doing so. You can connect your gas generator directly to the home's main transfer switch or to the dedicated generator input. Remember to change the input current when using your gas generator to not exceed its capacity, otherwise you might damage it.

Item is great second one but delivered to wrong house
