SUNGOLDPOWER UL1741 SPH6548P 6500W DC 48V Split Phase Solar Inverter,120V/240V AC Input/Output (settable),Built-in 2 MPPT Solar Controllers,Max. 140A Battery Charging,Inverter Charger Support Parallel

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 watts 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 this 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 the grid is 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 if using it as grid. This inverter allows me to significantly reduce my electrical bill and produce my own energy during emergencies without being outrageously expensive.

Excellent customer service. Couldn't be happier with the product. It is giving me all power it has advertised.

So far so good have it wired with 6 awg to main panal outside to inside to inverter then inverter to inside panel but wired to where it can be bypassed if needing to bypass invertor only thing i see which is kinda buggen me is discharge times led would stay solid so u dont no whats being used ac or inverter

Inversor de Corriente Eléctrica de muy buena calidad para paneles solares

Muy buena calidad

I am in the process of building an off grid system with SUNGOLDPOWER 6500W solar inverter.So far the inverter is working well.I threw everything at this 6500w inverter to try to run,TV, microwave, coffee maker, all runs well.I had a few questions and sungold response quickly. highly recommend it.

They shipped me a faulty product. I notified them. And they are making me pay to ship it back. In order to fix it. That is just wrong!!!!

I own 2 of these 6500W inverter now, configured for split phase 240v. It's simple to connect and the setup is easy. The solar controller is much higher capacity than other similar models from other manufacturer. Each inverter has 2 MPPT and the Max. PV input power is 5000W +5000W=10KW.We’re completely Off-grid, this model is very friendly with us.Will buy more to expand our system soon.
