First time owning a generator. I am very pleased!! Used for powering my refrigerator/freezer and 9000 btu A/C portable unit. Roughly 2400 watts usage to power and get about 10 hrs of run time on 4.3 gallons in tank. Been running for near 75 hrs straight. I did change oil (full synthetic). Be sure to get the “magnetized” dip stick/plug for this generator. It will collect all shavings in oil.

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

This folding solar panel snaps closed into a very convenient suitcase shape that carries well. The handle is comfortable to hold and the weight is reasonably well balanced so it doesn't tire your hand much. The outer pouch that houses the MC4 connectors makes a good place to stash an MC4 extension cable and possibly a charge controller, if needed, though you do need to take care not to lie the panel on top of the bag side and crush it. The bag section has two zippers, which you can bring up tight on either side of the power cables while they're sticking out of the bag to keep it mostly closed, but it does allow some dirt or water to get in during use if you aren't careful. This folds and unfolds easily, it has a little bit of wiggle to it that is more forgiving than some very firm "folding" panels, and there are button snaps and magnets to keep it from popping open unexpectedly. Although it has four panel sections, it only has three fold-out kickstands, and it does unfortunately tend to sag in the middle on the panel section without one so that you need to put this out very carefully to keep it straight. The wiggly body and light weight make it easy to knock over by wind gusts, and you might be better off just lying it flat on the ground facing up or against a wall or fence on very blustery days. The little sundial built into the handle makes it easy to get the perfect angle, it's a nice little bonus I haven't seen on other panel brands. At perfect alignment in high altitude Southwestern US mountains on a hot summer day I measured 23.4 volts and 6.37 amps directly from the panel, which using the formula of amps x volts = watts comes to a massive 149.05 watts without load, so this definitely gives the full rated output, and even over-performs a bit in ideal circumstances. The material of the panel faces is a kind of transparent textured plastic-like stuff, which is pretty tough for its weight, and washes off easily if it gets muddy, though bits of dirt or dust can collect in the little crater sections and need liberal splashes of water to clean out. The overall weather resistance of this is spectacular, minus the bag section needing to be open for the power cables to stick out, but that part is on the back/underside and easy enough to keep dry from most rain spells. I tried this with a charge controller and battery and a portable power station, and both charged up great. This gives good, reliable power, even as the sun moves across the sky and the angle doesn't stay perfect. I was absolutely pleased with how well this performed. The carry shape is great, and it is light in hand, though it is easier to knock over by wind than I'd like and I didn't enjoy the four sections but three legs, which made it try to sag in the middle a little. It is very weatherproof and easy to clean, and is pretty rugged, but you need to use care not to ever crush it, because it is fragile without a metal back plate. The built in sundial was cool, and when angled perfectly this absolutely meets and even beats its rated output. Overall I was really pleased with how well this travels and how powerful it is. It does have a few minor shortcomings, sure, but I am still quite happy and would gladly choose it again.
