Hi Deonvaa, I would recommend a 5.6kW OGS5.6 inverter made by Voltronics & marketed by Kodak. Pair this to a 5kWh Livoltek BLF51-5 Lithium Iron Phosphate battery. I'm not sure of your budget so I'm actually recommending what I would use & what I would recommend if providing a consultation for someone.
The sub 5kW inverters unfortunately I have found to have lots of clones & also are 24V systems which I'm not fond of at all. The 48V system is just safer with less amps pulled & smaller cables to work with. 
However, please don't let me tell you that this is the be all & end all of suggestions. Many guys know the sub 5kW market much better than me. 

I've just got a Fivestar 5kW "wifi" inverter for R14500 (the wifi means it comes with an ability to track your usage), and a Pylontech US2000C battery for R16000. My electrician installed it, not sure exactly what he will be charging for installation but it won't be that much.
It works like a dream to power 2 desktops, 3 laptops, all our lights, fridge and a small (100 litre) chest freezer. We didn't even change our bulbs yet for LEDs but are going to. I know that I have too few batteries for the inverter, but the price between the 5kW and 3kW inverter wasn't much, and I can grow my system later. I'm intending to buy solar panels first, electrician advised to get about 12. 

I have both and find the Hubble performs better starting home type fridges. I have not done comparative tests on capacity as the Mecers have been in use during LS events by the previous owner. It would not be fair to compare 200Ah that are a year old with Hubbles that are 9 months old.

This Revov is also a nice battery . Comes with bluetooth BMS so you can see all the battery parameters on your phone which is nice. Alternatively look at the Pylontech UP2500 if you want a new battery. You will get about half of the 2 Revov's capacity for about the same price.

Two of the S-120 Hubble should meet your needs, and pricing is in the ballpark of 2x200Ah AGM batteries, with more cycle life.

My call will also be 2 x S-120. In Nov I bought 2 running on a Axpert clone. When fully charged I get 3kWh up to the point of cut out when the voltage is still a good 25V. These are the 100Ah S-100's. No point in discharging to a lower level.
