SUNGOLDPOWER UL1741 6500W 48V Solar Inverter,120Vac Input,Pure Sine Wave All in One Inverter, 120A MPPT,120A AC Charger (Parallel + WiFi Monitor+Batteryless + BMS Support) Hybrid Inverter SP6548

Wonderfull produst vety good price and exelent service so far. More in the future pics

Installed 06-10-23. Installation was fairly easy other than doing it by myself. I used three strings of ten panels in series and then paralleled them into inverter input. With a total of 3,000 watts, the system seems to be working fine. By the way the first unit had a dead screen but this unit seems fine. The phone app is nice but I saw nowhere in instructions that the default password for Wi-Fi module is 12345678. Discovered that by searching internet and then I was able to connect to the module. Being able to monitor system away from home is nice but it is not exactly real time because it takes 5 to 8 minutes before the app updates the latest info. I believe it is the lag from going to their servers and then to the app. It needs to be installed behind a door as the fans can be heard anywhere in the house.

If you're looking for a very capable inverter that can run 120V or 240V Split-phase, or even Three phase, stop looking, buy 1, 2 or more of them. They have deals on entire kits. I have compared them to Victron and they are nearly as good. While they don't have all the features or connectivity, the expansibility and capability of these systems are insane. Fully maxed out (6 inverters) you can connect 48kW of panels providing over 300kW hours of power a day! (assuming 6.5 hours of usable sunlight). I may upgrade to Victron someday, but it will cost me significantly more to get what I have in these.I have two of these inverters configured as Split-Phase 240V US. I love this inverter not only because it's UL listed (rare for inverters) but because compared to a "all-in-one" split phase system that weighs a ton, while there are two, they are much lighter since each one handles each phase of the 120V. I have a 6kw Growatt (Not UL listed) 240V split-phase unit that I quite like as well, but compared to quality and performance of this unit, it's great!I have 28kW of LiFePo4 batteries hooked up to these inverters and 40 x 240W panels that run just about my entire house. It can easily run two 1+ ton mini-splits plus a house-full of electronics. What's crazy is this barely touches the total capacity of this system.With just two of these inverters (you use the parallel cable to connect two or more of them, expandable up to 6!!), you can run upwards of 16kW of panels (4kW+4kW MPTT controllers per inverter). The built in charge controller easily pumps 100+ Amps DC into my batteries and easily gets them to 100%. My setup will last through the night and all day. If you don't have enough juce, the built-in AC input can pull from grid or be ran via a generator. Use SolarAssistant to monitor and you've even got full remote management. The built-in app is okay, it definitely works, but could be better. It's far better than Growatt or other brands. The built-in WiFi works really really well. I use a USB cable to monitor the systems as well.These inverters are not nearly as heat tolerant as the Growatt. At 106 degrees ambient, they run over 170 degrees and shut down. I hardly fault the inverters, as I need to find a cooler place for them, the Growatt kept working. Maybe some better fans would help Sungoldpower...I'm hoping that my new BMSs (they now support Pylontech over RS485) will allow for battery communication, as currently I'm using Voltage settings for the calculation of SoC.Overall, I cannot say enough great things about these inverters. I've had them installed for around 8 months running just about everything and plan to keep expanding. Their support has been great and am exicited to help others with thier solar journeys!

It's all worked as described and is running my house currently! I recommend sungold to anybody

I purchased two sp6548 inverters and after i mounted them i went to hook up the pv. A lot of smoke came out of one inverter. I contacted customer service and they asked for pictures. i sent pictures of model,serial, and the capacitor. They then asked if a new capacitor would be fine, and i said yes. after a couple of weeks i asked for a delivery time. customer service replied that the parts were in customs.Yah right i thought.one week went by and i kept looking in the mailbox for a part. when i walked in the house there was a package.To my suprise they didn't send a capacitor but a whole main board. Sungold power has my vote for customer service,and the two inverters are working perfectly.

I have been using 2 SP6548 inverters from SunGoldPower for 3 months and I am very happy with these inverters. They are configured in split phase mode (120v + 120v) for a maximum 55 amps at 240 volts (or 55 amps per 120v line).Meant to charge a hybrid EV (still waiting for the EV) but also used to feed the emergency/generator panel which have circuits for the furnace, water heater, fridge, freezer, and lights.No issues at either split phase or single 120v phase.Second picture shows their battery consumption in split phase mode without load and with the PV input off. It consumes 3.5 amps x 53.52 volts = 183.86 watts / 2 = 91.93 watts per inverter.SunGoldPower provides excellent support and have put extra effort to help when I have questions or need support.Pros: Label on the units say UL and CSA approved (likely qualifies for Canadian grant)Cons: fans can get noisy with high loads and idle consumption is high.

Let's start with company and customer service: the ordering, processing, communication, and shipping were very good. I received 28 panels on two separate shipments (I ordered twice), and all panels arrived in perfect working condition.Tested the inverters with the battery bank, and they work great! Aso, we tested charging the batteries with the grid, just in case the solar was not enough or if the battery bank is low on capacity and the power-assisted also worked without any hiccups. I will buy from them again anytime.

I am a solar installer in Cincinnati. This is for an off grid pizza truck and I have to say the system is working extremely better than I thought it would. We are running three refrigerators and AC unit lights and surveillance cameras. We’ve done a battery test with all things running for 36 hours and the system operating exactly as it should.
