Question Solar Inverter WITHOUT SOLAR PANELS

Why don't you just get a LiFePo battery charger? About 1/4 to 1/10 the price of an All-in-One inverter.
 
What are you trying to accomplish with this inverter? Why buy MPPTs if you don't need them?
I have the same issue.

I want to do this because the current inverter isn't hybrid, and I don't want to change it.

But i want to add batteries, and i try to figure out if there are inverters out here that can only make AC/DC and DC/AC conversion for batteries and no solar attached, clearly this makes sense only if this solution is cheaper than replace the existent inverter.
 
You look for an inverter and a charger.
You could buy the 2 separately, possibly save money that way.

Also if one component breaks, you replace only 1, not both.

The following is an example of what you look for, inverter plus charger but no MPPT

I need 6000 W, this cost 1 Kusd in this page.

This one 350 USD https://powmr.com/products/6-5kw-48...0vac-split-phase-supports-6-units-in-parallel but has solar .

Is it possible to run without solar? is there another option?

Yes I could use a battery charger but I dont have the DC/AC conversion.
 
Just use standard inverters not made for solar.
I have a 600 watt inverter made by Trip lite I bought in the 80's that you can run off your car battery or you can charge up your battery with a standard wall charger or generator.
Still works great.

I started out with an inverter/charger that had no solar and charged from the grid or a generator. I added solar later. I see no need to buy something with an MPPT if it isn't needed.
 
There are several inverters out there that don't have MPPTs built in. At 6000W, you're right in the middle of the dead zone for Victron kit (and I'm not sure that would match your budget). Sungold Power has those beasts like the one linked above -- those are low frequency too IIRC, pretty solid. They may have a smaller one (maybe 8000W) that would do what you want.

As long as you have battery / AC you should be fine with any inverter I've seen, with or without a built in MPPT. I considered doing my build without solar at first too. With the right setup, depending on what you want, you could have battery backup + forced discharge at expensive times of day for certain loads. Then charge at night when it's cheap.
