Three main things are driving this: 🔋 (1) Larger Battery Cells: systems with larger format cells (≥300Ah) were 5% cheaper than those with smaller cells. 👣 (2) Higher Energy Density Containers: 20-foot containers now reaching 5+ MWh storage capacity, with 4MWh+ .
Some common problems are grounding issues, broken connectors, and bad terminations. Always plan for what your system needs before you start. Always pick solar panels with the same voltage and current.
