Y&H 3600W Hybrid Solar Inverter DC 24V to AC 110/120V Pure Sine Wave, w/ 120A MPPT Controller, Dual AC Output, Max 4200W PV Input, Lead-Acid/Lithium/Battery-Free Use, for Home Backup, RV, Off-Grid

​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.

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 functions Cons: -could not get this inverter to integrate with the "Main" or grid -several of the options choices in the set up menu did not exist IE: 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.

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

Funciona muy bien.

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.

La mejor inversión q vas hacer lo compre para mi familia en Cuba lo recomiendo 100 %

This inverter lists load of promising features that do actually work but only for few days. That's when it quickly starts exhibiting unusual behavior like sudden high residual AC voltage readings at the battery terminals, batteries start to drain under no load, failure to charge batteries, etc. I've thoroughly and methodically tested each setting to rule out any user error on my part. The only way to fix the problem is to reset the inverter back to factory, then again within few days same issue. My guess: I think there is a sudden DC power mismatch on the charging side. I decided to return the unit as I don't think this is a safe product.

Constantly kicks off from generator every few seconds despite trying multiple generators and settings and the settings are not intuitive. Wish I could return this

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