48V 5000W Inverter, Including Solar Controller, Pure Sine Maximum Off-Grid Smart Integrated Machine, Suitable for 48V Lead-Acid/Lithium Battery

It comes configured for lead acid battery, and the entire unit will remain unpowered if you hook up LiFePO batteries + the AC.. So, wire the AC only at first, then configure the battery settings. Then you can connect the battery. Using this on a boat, Marina lost power in a storm and I didn't even notice. Switches between power sources in milliseconds so there's no flicker or anything.

I was looking for a all in one style solar inverter for an off grid mini split ac system and stumbled across this one. I was pleasantly surprised that it was smaller than I thought it would be, making it easier to fit the space I had available for it. It is easy to program and get set up to my needs. It controls the power to the ac great and meets my needs in managing powering the ac system and keeping the batteries charged off solar. It seems well built I have been using it for a month with no issues The things I don’t like: 1. The lights on the front always flash, I wish there was a way to make them shut off when the main screen goes off. Easy enough to fix with some electrical tape over it, but still, would be nice to control it 2. The cooling fans are pretty loud, much louder than any other electrical equipment with cooling fans that I own. And it’s not an air whooshing/white noise sound, it resonates like the blades aren’t balanced, similar to a vibrating phone But the fans don’t stay on for long, it runs very cool outputting 750w for the ac Overall I would recommend for an out of the way area where the fans aren’t an issue. I will update the review if anything changes

It is time consuming to get everything out of this unit but reading everything over I realized I had to run 12v solar panels parallel in pairs and settings had to be set for the lifepo4 batteries I have 800watts of solar and in full cloud I had 750w of solar and 800 full sun ,this will run my AC once I had adjusted setting once again and 4-100ah lifepo4 will last 3.5 hours without solar input .I wish the wifi adapter came with it !

It is critical that you configure this unit for LiFePO4 batteries before you connect them. Hookup AC power, configure the unit. Shut down the power, connect battery cables. Power on unit. MAKE SURE TO CONFIGURE all aspects correctly. The defaults I believe are for their battery models, which are great if you're using them. I'm not, so I had to change a couple parameters including charging output down to 20A. DOING AWESOME NOW. The transfer time is imperceptible so the computers and my CPAP don't even notice. Used 4 AWG car starter cables from Tractor Supply for the battery as Amazon doesn't seem to honor their delivery windows anymore. My 24V 100AH battery lasts 4-6 hours depending on load. Hope to put ~1.5kw of solar on this in the near future. All in I paid ~$300 for this unit and $300 for the battery. Not bad for 3KW with all the trimmings.

This inverter does work but the preprogrammed internal settings really limit its value and usefulness. If you running 6000watts of solar and only using 2000 watts you’ll most likely be happy with this inverter. I was making 2100watts of solar and using between 1200-1600 and the unit would not charge, meaning it was wasting 500-900watts of usable power. It’s got some preprogrammed setting that shuts off the charging at some very high percentage. It also wouldn’t recognize the battery brand I was using (echoworthy) which is a fairly prominent brand, not some random generic brand.

Wow! This is a great, simple to setup solar charge controller! It is VERY easy to setup for a LiFePO4 battery, which I haven't seen anywhere else at this price. I bought three of them and they all work well. This looks to be exactly the same as the Bateria 10a charge controller (https://www.amazon.com/Controller-Bateria-Power-Display-Multiple/dp/B09NGYLP8C?th=1) and also includes the connectors. You can read more reviews of this charge controller at that link. If you disconnect the solar panel and battery from the charge controller and reconnect *it will* save all of your settings. I am pulling 6.5-7.0 amps in full sunlight with a 12v 123w panel, which I believe is max. vmp for this panel (123w/18v = 6.8a). (The Batteria version page says that max. input panel power for 12v is 150w.) As another reviewer has mentioned it would be nice if the main display flashed to solar input amps since I find myself looking for that info often. I like the simplicity and durability of PWM over MPPT. At current prices I'm better off buying another panel (Newpowa 100w 12v currently selling for less than $70) and another one of these charge controllers (and some 12/2 or even 14/2 landscape lighting wire) than going with MPPT. Have fun!
