Are you wondering how many batteries are needed for a 3000W inverter? In this video, I will provide you with surprising insights, especially since many guides often get this wrong. I'll explore two examples: one with a lithium battery and another with a leadacid battery, to demonstrate the ideal setup for your needs.

Many people use a 3000W inverter with just a 12V 100Ah battery, leading to early battery failure. I'll show why this happens and what you should do instead.

In this detailed guide, I'll cover:

The importance of limiting current to 100Amps in an offgrid solar power system, and how it leads to reduced wiring costs, cheaper charge controllers, and higher efficiency.
The calculation for a 3000W inverter, demonstrates why a 48V system is more efficient and costeffective.
The concept of Crate for both leadacid and lithium (LiFePO4) batteries, and why it's crucial for battery longevity and performance.

I'll also provide a practical example using lithium batteries, showing the calculations for a 48V system and why it's a superior choice. Plus, I'll repeat the process for leadacid batteries, highlighting the differences in size, weight, and efficiency.

Remember, always fully charge your batteries before connecting them and respect the Crate to ensure maximum lifespan.
