Is battery storage worth it in Atwater under PG&E NEM 3.0?

Under PG&E NEM 3.0, battery storage helps Merced County homeowners maximize solar value by storing midday production for evening use. In Atwater, summer electricity rates peak in the evening when solar production has stopped — battery storage lets you use your own solar power instead of buying from PG&E at peak rates.

What is the outage and PSPS risk in Atwater?

This valley floor community has low PSPS risk. Battery storage is still valuable for NEM 3.0 optimization — storing midday solar for evening use instead of selling back at low export rates. Low-moderate.

What makes FranklinWH different from Tesla Powerwall?

FranklinWH aPower uses AC coupling, which means it works with any existing solar inverter without replacement. Tesla Powerwall 3 includes its own solar inverter, which is ideal for new installations but requires a Gateway for retrofits. FranklinWH also stacks to higher total capacity (up to 15 units vs 4 for Powerwall). Robbins Energy installs both and can recommend the right fit for your situation.

Can FranklinWH power my well pump during an outage?

Yes — FranklinWH aPower's 10 kW continuous output can handle most residential well pumps (typically 1–3 HP). Robbins Energy assesses your well pump load during the site survey and sizes the battery system accordingly. For properties with large agricultural pumps, we may recommend multiple units.
