Tesla Powerwall – 2nd Generation

Tesla Powerwall — 2nd Generation

The Tesla Powerwall (2nd Generation) is a compact, high‑density home battery designed to store energy from solar (or the grid) and deliver dependable backup power during outages.  Gruber brings four decades of hands‑on experience with critical power systems, UPS infrastructure, and battery reliability — so you get more than a box on the wall: you get guidance, planning, and real support.

We can guide, direct, and support your Powerwall installation from concept to commissioning — including load planning, backup panel strategy, installer coordination, and post‑install troubleshooting. We also work closely within the Tesla ecosystem and can coordinate with your Tesla‑certified installer to help ensure the system is configured the right way for your home and goals.

Why power systems fail — and what Powerwall solves

• Grid outages — automatic backup keeps critical loads running.
• Peak rates — time‑shift energy to reduce expensive peak usage.
• Solar curtailment — store daytime production and use it at night.
• Poor load planning — the #1 cause of “it didn’t meet expectations.” We fix that up front.

Our solution — 40 years of critical‑power know‑how applied to your home

• Backup load strategy — define what must run, what can’t, and what’s optional.
• System sizing support — determine quantity of Powerwalls for your runtime goals.
• Installer coordination — align electrical scope, gateways, networking, and commissioning steps.
• Clean commissioning — verify operation, app visibility, and backup behavior.
