SUNGOLDPOWER 6500W 48V Solar Inverter, Built-in 2 MPPT Solar Controllers, Max 140A Battery Charging, AC Input/Output 120V/240V(settable),Pure Sine Wave Inverter(Parallel/WiFi/BMS COMM)

It has been running for about 6 months now and working as I planned. Currently I only have 3 lightly loaded circuits connected with no solar panels attached so basically it is running in UTI mode as a UPS. I plan on moving the deep freezer and refrigerator circuits to the panel and adding 3,000 watts of solar when I get a support structure built. So far it is working flawlessly with my 2 Vatrer server rack batteries. I dropped one star due to the complexity of the manual and clarity of the instructions but it does exactly as advertised and appears to be a well built unit. One thing that is more of an annoyance than anything is the cooling fans constantly cycle on and off, maybe every 8-10 minutes. If you are nearby trying to sleep, say in a small cabin, unless your hearing is diminished, it might keep you up at night. If it ran constantly at a slower speed until more cooling was needed it would be better, in my opinion. Works great and barely flickers the lights when it switches to battery when the power drops.

Lo compre para la instalacion de paneles solares en Cuba ,el material es muy bueno ,esto es muy efectivo funciona perfecto y resuelve nustros problemas en la isla sin electricidad

Well so far so good. wiring was straightforward. One huge thing you should know is; In the past i had a different AIO inverter but every time it went from Utility to battery my TV woukd turn off. no matter what settings I tried to adjust the tv would turn off. However with this sungold 6500 watts 2 phase inverter, my tv does not turn off when it goes from utility to battery. I am happy with it. the wifi app is not as useful and does not even give you tbe battery voltage just a SOC which is not really helpful. Over all I recomend and say this is a much better purchase than the lower costing units.

Es inversor es de los mejores q e tenido ; con un sistema de protección q lo destaca ; y muestra la información completa en la pantalla del sistema fotovoltaico

Llego en buen estado gracias ! Update , después de 122 días utilizándolo por el día solo con una batería 5k y 2600 w en placas , me ha bajado la luz a la mitad , cocino , puedo prender tres consolas ( obvio si cocino apago las consolas ) . Mi esposa ah prendido sin querer la electricidad y ah entrado al inversor , protegiéndose al instante . Muy complacido con mi primer inversor ! 👍
