SUMRY 3600W Solar Inverter Charger, DC 24V to AC 110V Hybrid Inverter with Built-in 120A MPPT Controller, Pure Sine Wave PV Power Converter, Supports Battery-Less or AGM Lithium Battery

I bought this inverter because my charge controller died. When shopping for a new one I found it was cheaper to buy a hybrid than a new controller it replaced a 6 year old renogy 2000 watt smart inverter and rover 40 mpptSo far I'm very impressed Im running 6-100 watt mono panels and 4-100 amp hr amg batteries on my camp trailer and 1- 100 amg for house lights of my original converter which is being ran by inverter. I havent had to plug it in for over a week running 2 tv's and satellite receiver and micro wave. running fridge off gas.I've been able to run my ac during full sun batteries dont drop below 23 volts.I plan on adding 3 more panels so batteries stay full while using ac.Function are easy to learn after reading instructions a few times there's alot to take in.Hopefully it keeps impressing me.

Price and ease of use

The media could not be loaded. I’ve got to say, this SUMRY HGX-4KW hybrid solar inverter really had me sold at first glance. Between the clean black exterior, the slick tempered glass top with that big 6.25-inch LCD screen, and the promise of 4000 watts of pure sine wave output plus 8000 watts of surge power, it looked like exactly what I needed for my off-grid setup. I’m running everything out of a travel trailer with a 24V solar system, and I needed something that could handle solar, battery, and generator input. This model claimed it could do all of that, and the price seemed totally reasonable for the feature list, especially with that high 140A MPPT charge controller and a decent PV input range. I even liked the style—it actually looked like something that belonged in a modern solar setup, not an old farm shed.But man, things went downhill fast. Wanting to get everything dialed in, I reached out to SUMRY support before even firing it up, just to be sure I had the right battery settings there’s 30 different settings. They gave me about three or four setting values for my LiFeP04 battery bank, and then basically told me not to worry about the rest. That should’ve been my first red flag. Because after installation, I fired up my generator to give the batteries a boost and noticed the inverter recognized the AC input but didn’t actually do anything with it. No battery charging. No AC output. Just… silence. And then, at 1:30 in the morning—because these things never fail at a convenient time—everything shut off. It completely drained the battery bank from 50% down to zero. Now, this isn’t our first solar rodeo. We know our usage patterns, and there’s no way that amount of power was used up naturally. Turns out the inverter itself is an absolute hog, even just on standby. That’s a total dealbreaker for anyone living off-grid like we do, where efficiency matters more than cosmetics.And I wish that was the end of the headache, but no. Over the next 24 hours, I went through endless back-and-forth with customer support, trying to figure out why the inverter wouldn’t use the generator or any AC input the way it should. I beg them multiple times to confirm all of the settings that I had with what should be because I felt that possibly one of the settings could’ve been off. They never provided me with a list of all of the settings like I requested, and then that’s when I found out the real catch—this thing only works with AC input if you basically do a full reset every time. You have to shut off all loads, disconnect the batteries, turn the batteries back on, then turn on your generator or AC input, wait a few minutes, and then turn on the AC output. That process has to happen every time. That’s not hybrid operation—that’s a workaround that makes absolutely no sense, and it completely defeats the purpose of having a generator or grid backup for your solar system. I’m not trying to run a science experiment every time a cloud rolls in.Not to mention another major thing is that it kept attempting to backfeed power into my generator. Even though when I reached out to them, I let them know. I was using the generator, and they assured me that this model does not back feed into the grid or the generator. It nearly blew up my generator! As you can see in the video it recognizes my solar also recognizes the load that I have and that it’s charging the battery. Then I turn on the generator and it recognizes that for a split second and then you’ll see that the battery tries back feeding into the generator. This was just a headache all around! Almost ruined a $3000 generator set up!And here’s the worst part—that constant cycling of power just to get AC input working is brutal on sensitive electronics. I’ve got a microwave and a smart TV in the trailer that do not appreciate the power surging on and off. Plus, trying to explain this mess of a procedure to anyone else in the house feels like I’m giving instructions to launch a rocket. At that point, the inverter’s flashy design starts to feel like a cruel joke. All the great craftsmanship and “high-quality” materials mean nothing when the thing can’t even do what it claims. And the idea that this is a reliable, functional hybrid inverter? Not even close.Honestly, the only thing this inverter does consistently is frustrate me. If I just needed something that looked cool on the wall and lit up when I touched it, maybe it’d be worth the money. But I needed something that would help keep the lights on, not something that makes me jump through hoops to get basic backup power. I don’t know how there are positive reviews for this unless folks haven’t tried to use it with AC input yet—or they were paid to stay quiet. If you’re serious about solar and you’re living off-grid or prepping for emergencies, do not waste your time or money on this. It’s a headache in a pretty box.

This is the second family product we've purchased. It works wonderfully and does its job, very, very well. This is a very good Hybrid Inverter, work fine in our Solar System. Shipped and delivered very well. Good Amazon Seller.

I loved the interface and price but the specs are false. It shows it puts up 10% more power than real life measurements. So this is actually a 3.6kw inverter. Also the charging amps of the batteries are way less than advertised. Most I've seen was 60A for few minutes then it drops down all the way to 10A. It is not the battery as other inverters were able to charge that battery at constant current.The output voltage was 118V, no load and freq was 59.8HZ, so both a little off.

if you want to camp car. then solar panel should be minimum 55-65 volts. given panel will not handle.

installing, work perfectly. bring more.First Priority Solar and working in SBU and SNU when Panels does not support all house connected and Charge the battery with solar or facility.Reset to factory settings, from 50Hz to 60Hz and configure your battery settings so that it accepts facility.
