Y&H - 3600W 24V DC to 110V/120V AC Pure Sine Wave Solar Inverter with 120A Mppt Solar Controller, Two AC Outlets, 4200W Max PV Power Input, for Battery

​I am genuinely impressed with the performance and features of this Y&H 3600W Solar Inverter. It's an absolute powerhouse for a small to medium off-grid or backup system. ​The Pure Sine Wave output is clean and reliable, which is essential for safely running sensitive electronics in my home and workshop. The integrated 120A MPPT Solar Controller is the biggest selling point—it simplifies the setup and maximizes the power harvest from my panels, making it an incredible value compared to buying two separate units. The Max PV Power 4200W Input gives me plenty of room to expand my solar array down the road.

Fans kick on way to often and draw more power then most others on the market

This inverter has been working fine for me. Tested out on a washing machine, gas dryer, fridge, 1500W induction cook top, all without issues. Got 1KW panels 10kWh lifepo4 batteries wired to it. Only issue is the power outputs and inputs are a little noisy (RF emissions). Adding common mode chokes and ferrite beads fixes the issues. The other thing is it will cycle if the inverter is off and the panel can't provide enough power at dawn. Leaving it on or disconnecting the panels keep it from cycling.

3 months into it now. I love it. High quality, clear instructions and relatively quiet with fans running. Simple for solar, high voltage series setup. I have two minor issues. 2 gauge wire is all your going to get in there. It's all I needed but it's tight. It is about an inch thicker than stated which almost got it returned. Fortunately I figured it out. LED is dim during bright sunlight and bright at night. I would definitely purchase again.

Read the product description before buying. This needs 60 volts to work. My set up was not able to provide that. I have no idea how it works bc returned it.
