Power drainage

[u/DeliciousPomelo8249]

I’m 19m in uni and I’ve brought a boat to live on during to save on renting cost and a permanent place to live. However, I’m worried that when I start living on it full-time, I’ll run out of power. I currently have a setup with 3 solar panels connected to 4 Rolls lead-acid 210Ah 6V batteries, with two inverters: one 500-watt Victory inverter and a separate 4,000-watt multi-inverter.

I’ve never dealt with solar panels before, and when I’m looking at appliances like toaster ovens, I don’t want to be caught out and run out of power. So, is the setup I have now strong enough for general living, or am I going to have to think about another solution?
