DIY Powerwall - Build your own battery energy storage

What do you need to build your own DIY Powerwall?

Embarking on the journey of constructing your own DIY Powerwall requires precision and a clear understanding of key components. In this guide, we'll delve into the essentials to help you navigate the technical aspects of your Powerwall project.

  1. Choosing the Right Cell Type. The first step is selecting the appropriate cell type. LFP prismatic cells are favored for their large energy capacity, while Lead Acid AGM batteries offer a reliable, low-tech alternative.
  2. Voltage and Capacity. Determine the voltage and capacity that align with your project goals. Configuring 16 LFP cells in series at 51V is a common choice for compatibility with many battery inverters. Stack cells in parallel to achieve your desired capacity.
  3. BMS Selection (if using lithium). For lithium cells, a reliable Battery Management System (BMS) is crucial. The Nuvation BMS is a recommended choice due to its high quality, reliability, and UL certification.
  4. Inverter Options. Selecting the right inverter is critical for optimal Powerwall performance. Explore reputable brands such as Sol-Ark, Outback, Schneider, Victron, and Samlex.
  5. Planning Your Build. Now, let's focus on the practical aspects—planning your Powerwall build. The most challenging aspect lies in constructing the cells into a safe and efficient pack. Consider the following products to assist you in this process:
