With 1,000 watts of panel power (4×250-watt panels, 3x 330-watt panels), you could easily get enough power to charge 2x200ah batteries, and probably three or even four if your energy usage is moderate.

The solar panel to battery ratio is a crucial consideration when designing a home solar energy system. It determines the appropriate combination of solar panels and batteries to ensure efficient charging and utilization of stored energy.
The size of the solar panel required to charge a lithium battery depends on the lithium battery's capacity. What size solar panel do I need to charge a 100AH battery? 100AH Lithium Battery x 12V = 1200WH 1200WH / 8H = 150W of solar panels. What size solar panel will charge a 120AH battery?
Batteries needed (Ah) = 100 Ah X 3 days X 1.15 / 0.6 = 575 Ah. To power your system for the required time, you would need approximately five 100 Ah batteries, ideal for an off-grid solar system. This explained how to calculate the battery capacity for the solar system. How to Calculate Solar Panel Requirements?
Conversely, a 300-watt panel charging a 100Ah battery would lead to significant wastage, as the panel would provide more power than the battery can utilize efficiently. For small solar setups under a kilowatt, adhering to the 1:1 ratio is generally a sound approach.
There is no 600 watt solar panel available. Instead, you need to combine two 300-watt solar panels to get 600 watts. The best place to buy such a setup is online for convenience.
