5000W 48V All-in-One Solar Charger Inverter

Have been running two of these for over a year now fully off grid In Hawaii. They have been amazing! We are admittedly heavy power users, we have 220v Air conditioning, 220v water pump, 220v induction stove, washer dryer. Never had an issue overloading the system..even when the ladies think everything should be on at once lol. Example if your doing laundry and cooking then the water pump kicks on the inverters give a beep but always cover the load. Couldnt be happier with them for the price they're much much better of a deal then the big names. I will and have recommended this inverter/charger to everyone that inquires about it.

I had a 3000 watt eg4 but it was horrendously loud , this is by far quieter and the mppt tracks way better with a 5000 watt output for a hundred dollars more... well worth it so far.. the wifi is a nightmare to hook up on any of these things

Very nice unit, I'm upgrading my off-grid solar fpor my camper from 1500w to this.
BUT, I'm also switching to LiFe batteries from lead.
Now, this unit can do it, old one could not.
However you need to read the manual,
then sit down with your favorite beverage and read it again.
And then struggle through the setup stuff.
I think if you have lead batts, its just plug it in and go.
But I had quite a head scratcher figuring out how the unit would talk to the BMS that runs the new batteries.

So far so good. I've had this hooked up for a couple days. been using this for about two weeks now in my enclosed trailer, I run a mini split and some lights and charge devices and it can handle everything well. Easy to hook up, but had to change some setting for the batteries and seems to be doing much better. It doesn't like the panels being in parallel so I have them hooked up in series and seems to work alot better.

This unit is a beast! I have run my whole house (within reason, we don't push it). We have run the following directly off of the inverter, refrigerator with tablet built into door (sensitive electronics), wine fridge (gas compressor on a battery backup), all lighting, television and all internet, complete office and electric heaters. We have had neighbors ask "how do you have power?", we have the system backed up with 2 Optima Red Tops, 6 solar cell array, 48 volt, 1200 watt that keeps the batteries topped. I also have a generator, but hope to only need it in extended dark days. I had a unit fail, never really found out why, but the company helped me diagnose the unit for myself, I sent a few pics, they did too, their support was just fine, very to the point, good things to check (fuses,etc), then when we determined this one failed, they PROMPTLY sent me a new one! I also purchased a second one (they are cost effective and perfect for me) as a spare, this way I have zero downtime if one fails. Excellent service, strong product, excellent support!
Edit: it is now 6/2021 and I would still rate this inverter a beast! Soon I will be asking this seller (Calpha Solar) what they have in a 220 volt with a little more power that this. Best clear, this inverter is friggin powerful, it just lacks 220 v and I would love more overhead. I invested in more batteries and I never really worry about this system. We are running a 4 bedroom house off of this beast. There are limitations, but my wife and I have adjusted well. It was a nightmare when I recently had family over. I had to explain, "please don't use the toaster, curling iron, microwave and dish washer and clothes dryer all on at once. It swamps my solar system". Nobody likes it lol, they learn that if they run too much, the system shuts down...only took one incident for then to figure, coordinate electrical activities...it's not hard, you just have to get used to it.
Would I purchase again "Yes!" and I would not hesitate!
