The FranklinWH aPower is a 13.6 kWh LFP battery with a built-in 10 kW inverter. It supports whole-home backup, stacks up to 15 units, and is compatible with most existing solar inverters via AC coupling. The aGate controller manages multiple units and provides monitoring through the Franklin app.
Hume is a remote mountain community in eastern Fresno County, located near Kings Canyon National Park at approximately 5,200 feet elevation. Served by ZIP code 93628, Hume has a mix of full-time residences and vacation properties surrounded by Sierra Nevada forest. The high elevation delivers two solar advantages: cooler temperatures that keep panels closer to their rated output, and strong unobstructed sun exposure from spring through fall. PSPS outages are among the most frequent and prolonged in Fresno County — PG&E regularly shuts down the transmission lines serving this area for 48–72 hours or more during fire weather. For Hume homeowners, battery backup is not optional — it is essential infrastructure.
Mountain properties with off-grid or near-off-grid needs benefit from FranklinWH's stackability — up to 15 units (204 kWh) for properties that need extended autonomy or true off-grid capability.
Three or more aPower units are recommended for mountain properties with extended outage risk or off-grid aspirations.
FranklinWH uses AC coupling — it works with any existing solar inverter (SolarEdge, Enphase, Fronius, SMA, etc.) without replacing it. This makes it an excellent retrofit option.
Whole-home backup is standard. The aGate controller manages load switching and provides seamless transition during outages.
Compatible with 200A panels. Some older 100A service homes may need a panel upgrade. Robbins Energy assesses panel capacity during the site survey. Mountain communities have the highest PSPS risk and may have limited grid reliability. Battery storage is essential. Some properties are candidates for off-grid or near-off-grid configurations.
Permits issued by: Fresno County Building Department. FranklinWH installations require building permits and PG&E interconnection approval. Robbins Energy handles all permitting across Fresno, Madera, Kings, Tulare, and Merced counties. PG&E NEM 3.0 interconnection required. Robbins Energy handles the full interconnection application, which typically takes 4–8 weeks for approval after permit issuance.
Mountain properties often have steep roof pitches. Robbins Energy designs systems for your specific roof geometry and sun exposure. Remote mountain community. Many homes built in the 1970s–1980s with 100-amp panels that require upgrading before solar installation. Fresno County Building and Safety Division handles permits. Service calls require advance scheduling due to remote location.

Under PG&E NEM 3.0, battery storage is essential to maximize the value of your solar investment. Export rates are low; storing solar for evening use avoids buying power at peak rates (4–9 PM). In Hume, 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.
This community is in a high-priority PSPS zone. PG&E regularly shuts off power here during high-wind fire weather events — sometimes for 2–5 days at a time. Battery storage with Storm Watch or equivalent pre-charge capability is strongly recommended for all households. Very high. Hume experiences 4–8 PSPS events per year, with individual outages lasting 48–72 hours or more. Remote mountain location with limited grid redundancy. Battery backup is essential.
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.
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.
