If you want use no transformer, you need connect the inverter directly to the power line. This is on-grid system. So you need not batterys. You sell your green energy to the public power line.

You can charge DC240V battery use some special MPPT regulator.

Transformerless Inverter

Here the answers:

For sure you can not use the thinner wires as normal wires which using in AC power system. .....

We can say it is easier for transfer to AC using tranformerless inverter. ... sunny-boy can fit very well for some KW systems.

Thank you. Since the system should be able to supply power at night it will also have batteries for storage and kept be tied to the grid to enable "net metering".
I'll also copy n paste your replies about "charging" to enrich this thread. Thanks again.

... to make any hook up to the electrical system. Solar panels are direct current (DC) and your electrical service is alternating current (AC). You need inverters and phase matching equipment to attempt these kinds of connections.

For a solar panels system to work correctly you'll need batteries for storing the power, wiring to handle the systems amps, phase converters, inverters, and high wattage solar panels to make your system worth while.

MPPT mentioned in earlier post
