Capacity Question

[JohnNSP]

I am trying to set up a solar system for camping that will charge my boat's trolling motor batteries. I'd appreciate some advice.

What I need to charge is four 100ah lithium batteries (three are LiTime TM batteries: https://www.litime.com/products/lit...pLPzCm9RKiI7dG48c4E6RSfGU-KhEAlRoCXAkQAvD_BwE) via a MinnKota 4 bank 10 amp Precision Charger (https://minnkota.johnsonoutdoors.com/us/shop/battery-chargers/on-board-precision-chargers?v=102071).

The challenge, in part, is that I'll be fishing during the day and need to charge at night. I need some sort of power station that can hold the juice from the solar panels and give me 110 power for the charger at night. A gas generator might be easier, but before I go that route I'd like to fully understand my solar options.

I've seen a bunch of systems on amazon that might work, but I can't figure out how much capacity I'd need in the power station to charge my boat batteries. Any advice or direction would be appreciated!

I think you can start with the following components.
Solar Panels: Capable of generating around 4000Wh per day.
Battery Bank: At least 4.3kWh of storage capacity.
Inverter: At least 500W continuous power rating.
Charge Controller: Suitable for the total wattage of your solar panels.
