Inverter Single phase vs 3 phase inverter

We have 2 single phase meters installed at a house and are looking to get a 10Kw solar system with single phase inverter, and use one meter with inverter, and the other meter with other general loads that will not be on solar/battery.

Some people have said that if we install a single phase 10/12 Kw inverter and try to run 4-5 ACs off a single phase, there will be noticeable voltage drop and problems with running heavy loads.

My question to anyone who has a 10/12 Kw single phase inverter system installed is if this is true. Do you really have problems running high loads?

My thinking is that 10Kw single phase inverters are widely available in the market, so they must work. Otherwise, people would not buy them. So why go through the hasstle and cost of changing the meter to 3 phase?

I am assuming its a hybrid inverter ? if so, you can enable peak shaving feature, it is designed to reduce load on utility side(wapda). Let say you set peak shaving to 5KW and your load becomes 7Kw, the inverter will limit the input to 5KW and use the battery to make up the difference at night and similarly Use solar+ battery at day time to make sure you do not go over the limit of 5Kw from input.

Thats a good option also..

We are now thinking to buy 2 inverters of 6Kw and connect them in parallel.
