Outage backup
Keep refrigeration, networking, medical, and lighting running through SDG&E outages. Critical-load circuits sized to the equipment that actually matters.
Battery Storage
Tesla Powerwall and battery storage built for San Diego homes and businesses
Battery storage is the difference between solar that exports for credits and solar that actually powers your home or business when the grid goes down. Perk Solar is a Tesla-certified installer and works across Enphase, Point Guard, and EcoFlow.

Tesla Powerwall 3
The Powerwall is our primary residential battery
Perk Solar is a Tesla-certified installer. Powerwall 3 is the AC + DC coupled system we recommend for most residential customers and small commercial sites — single-unit or stacked, whole-home or partial backup, sized around the loads you actually need to keep running.
- 01Whole-home or partial-backup configurations
- 02Storage-first NEM 3.0 design — built for self-consumption
- 03Time-of-use arbitrage tuned to your rate schedule
- 04Stack multiple units for higher-demand homes or businesses
When storage makes sense
Six ways San Diego customers use battery storage
Storage isn't one product — it's a strategy. We size around your real use, your critical loads, and what your utility rate is actually doing to your bill. Here's where we see the strongest fits.
02
Time-of-use arbitrage
Charge from solar mid-day, discharge during peak rate windows. Stops you from buying expensive grid power between 4pm and 9pm.
03
NEM 3.0 retrofit
Existing solar customers under NEM 3.0 lost most of their export value. A battery retrofit turns that production back into real savings.
04
Critical loads only
A smaller battery sized just to keep refrigeration, hot water, or business equipment alive during outages. Cheaper than whole-home backup.
05
EV pairing
Charge the EV at night from stored solar instead of grid power. Pairs particularly well with NEM 3.0 + Time-of-Use rates.
06
VPP-ready
Designed for future grid-services programs. When utilities pay for stored energy, your battery becomes a revenue source.
