Need more battery power for Vita550. Add an extra battery or diy a bigger and better solar generator?

I have decided to use solar power for my man cave. During the winter my maximum watts are about 150 due to me heating with propane. Summer will be the same 150 watts plus a Midea 8,000 btu inverter ac. According to Midea the total start up watts is 710 and from what I have read ongoing is about 500. Summer will be surge of 860 watts and 650 ongoing. I have 2 100 watt panels right now.

If I went diy what set up would be suggested?

Ac or dc or mix? Voltage(s)? 150 watts for a tv, sound bar, light? That seems low.

It's for a 32" tv, a socket fan/light, lamp with led bulb, phone charger, and laptop charger

EG4 3kW inverter
At least one 5kW battery.
I'm guessing you want at least two 400 watt (or larger) panels.
Return the 100 watt panels.

This is a man cave so at the most I will use it 3 hours a day.

I ended up contacting growatt about returning it and for some reason they told me to just keep it and they refunded my money.
My new plan is to use it to power everything I need but a/c and build a larger system for my a/c.
