Size your system once for the next decade of EVs, heat pumps, and multi-day outages.
Every installation carries substantial What goes into fixed project costsPermitting, inspection & interconnection: Plan sets, AHJ permits, inspections, utility interconnection, heat alarms, and code placards.Electrical tie-in & inverter: Hybrid inverter, electrical tie-in, breakers, AC/DC disconnects, and conduit.Logistics & overhead: Procurement, logistics, crew mobilization, contingency, and project overhead. regardless of system size. Once those are covered, the bigger you go, the more value you get per dollar—and while that’s true for any system, it’s particularly true with low-cost modular batteries.
Even if 48 kWh feels generous today, adding an EV, heat pump HVAC and water heater, and induction cooking doubles a typical home’s load right when PG&E’s evening rates peak (+104% over the last decade, per the Public Advocates Office)—while multi-day outages like the Mission substation fire demand more than a single 14 kWh battery can hold.
We’ve thought this through from every dimension, and we think we’ve identified a few key ways to provide you a smarter solution.
A bigger, smarter design philosophy only matters if you execute it well. Here is the proof in our recent Bay Area projects and the words of our customers.

“The value proposition is bang on. Installation was really professional. And the service is amazing.”
