If you need 10 kWh daily, select a battery with a 12 kWh capacity, allowing for 80% depth of discharge. Grid-connected systems often need 1-3 lithium-ion batteries.
Adding an energy storage battery to a residential solar panel system typically costs $7,000 to $18,000. The final price depends on what you buy and who installs it.
In short, For 1500 watt inverter you'll need two 12V 100Ah lead-acid batteries connected in series or a single 24V 100Ah lithium battery to run your 1500W inverter at its full capacity. the lead-acid batteries should be two because of their C-ratings.
So, in conclusion, for a 300 watt solar panel, you would need at least one 12V battery with a minimum capacity of 25 amp-hours to ensure efficient energy storage.
Expansive Solar Capability: Designed to accommodate up to 15 kW of solar input, this system maximizes the potential of your solar array, ensuring you can harvest and store an ample supply of solar energy even during low sunlight conditions.

- Rule of Thumb: The inverter's rated power (kW) should align with the battery's capacity (kWh). - Oversizing the battery can lead to underutilization, while undersizing may limit performance.
