Y&H 4000W Solar Hybrid Inverter DC24V 120VAC Pure Sine Wave Battery-Free Starting Built MPPT 140A Solar Charger,6.25 inch LCD Screen and Touch Buttons

I have been using this for about a month it seems to be doing a great.I haven't had any problems with it so far. The setup is fairly easy. Once you get it setup just let it do it's job.I would recommend this unit. It works great for a workshop, small camper. Runs everything in there that you need. Even the A/C

I am very satisfied with this Y&H 10KW 48V inverter. It runs stably, provides a pure sine wave, is easy to connect, has a clear menu, and the build quality is excellent.But the most important thing is the seller’s service. I had a non-standard question about parallel connection and compatibility with my system, and no one else could help me, not even forums or other sellers. I contacted this seller, and they responded very quickly, thoroughly, and to the point, helping me understand and set everything up correctly. Now my system runs reliably, and I am saving on electricity every day.Special thanks for their patience and willingness to help even after the purchase. It is rare to find such an honest and attentive seller. I highly recommend this inverter and this seller to anyone looking for a quality product with reliable service.

Pros:-this inverter worked without batteries-off grid functionsCons:-could not get this inverter to integrate with the "Main" or grid-several of the options choices in the set up menu did not existIE: option #1 should have three options UTI, grid first, SBU inverter first using battery, SOL, panel first) the inverter only had UTI as an option.-installation/user manual is not helpful. Doesn't even mention how to set up for use without batteries.-When off "main" or grid, with batteries, the inverter only produces 208V, not 240 Volts. And nothing would change it to 240V (no options in the menu) needed for most appliances, and EV chargers.These issues seem to be a software problem.Absolutely no info on customer/installer support.

Horrible customer service. Product work well. It is impossible to download the user manual.

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.

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.

Works really well does exactly what it says and is made out of really good material it feels more expensive than it actually is will recommend
