Y&H 4.2KW 24VDC Solar Hybrid Inverter AC220V Two Load Output Power, On/Off-Grid Built in 120A MPPT Solar Charger Max PV Power 6200W Input, for 48V Lead Acid/Lithium Battery, Supports Battery-Free use

Vesitle unit, fast delivery. The unit does work with lifepo4, I noticed someone wrote a review saying it did not. You have to set the charge limit as user defined and on 24 volt set it to 27 volt. I am using ten 24 panels rated at 200 watts and 4 100 amp hr Litime type lifepo4 batteries in parallel. The picture is from early afternoon in a partly cloudy day. It can be used as a grid tie or off grid inverter but this particular unit has an output of 220-240 volts, not 110-120. You can split the output from the unit into 120 with a sub box if needed. The batteries function like a generator to power the house if grid power goes down.

Functionality worked pretty good for the first week or so. Quality it was lacking in parts I believe cheap parts equal bad quality, definitely put out the 230 I needed. Didn’t have a lot of noise while running,which was great. Power quality lights kinda had a little flicker to it. Installation was easy. If the item actually worked, it would be a good value for your money. But unfortunately, the item quit working within one week everything hooked up proper to its manual wire size, etc.. and no response from the seller unfortunately go a different brand. There are different ones out there for the same price.

Was acquired to replace a faulty hybrid invertor - works for already a few moths with no issues. Setup was friendly but requires knowledge (now way to use such device with out knowing the fundamentals in solar systems)

I want to save everyone's time by saying do not buy these items because if the warranty expires and your inverter fails, you may not be able to find some of these components on the market. Second, the customer service is no kind of help you would message them, and it would take a couple of weeks before a reply. Now my suggestion is to buy a well-known brand and make sure you can get parts for it if you need to repair it. That's all from me; be safe.

* Do not purchase , do not trust Y&H service , unit was brick dead straight out the box , Y&H has absolutely Zero honor dealing with their defective products

The user a manual said that this solar inverter must not be used with a lithium battery

Other reviews had concerns about being 50hz it has a setting to change it to 60hz 240 for the us grid so far its all good we have had a few inverters and this one seems well made especially for the price the manual is for all 3 inverters including the 6200 they all have the same features the dust covers are a nice touch as well hope this help that's the questions I needed answered when I was comparing
