Real answers — what you actually need to know
💰 What does battery backup actually cost in SD?
Expect $10,000–$22,000 fully installed depending on system size and whether you need a panel upgrade. A single Powerwall 3 (13.5 kWh) runs $13,000–$16,000 all-in for most North County homes. Federal ITC (30%) applies if paired with solar — that's real money back.
⚡ Do I need an electric panel upgrade first?
Probably. Most San Diego homes built before 2005 have 100A or 125A panels. Battery installers require 200A service for whole-home backup. Upgrade cost: $2,000–$4,500. Some installers bundle it; get it quoted separately so you're not overpaying.
🔌 Powerwall 3 vs Enphase IQ vs LG RESU — which wins for SD?
Powerwall 3 is the cleanest all-in-one if you're adding solar. Enphase IQ is the best modular option — add more batteries later without rewiring. LG RESU is cheaper but the company exited the US market; avoid new installs. For most Encinitas and Carlsbad homes, Powerwall 3 or Enphase IQ.
🌍 NEM 3.0 — does battery storage still make sense?
Yes, and it's actually a better fit now. NEM 3.0 cut export credits by ~75%, which hurt solar-only. But battery storage lets you use your own solar instead of selling it cheap. Discharge during peak hours (4–9pm) when SDG&E rates hit $0.55–$0.65/kWh. The math is better than it looks.
