Madera sits 20 miles north of Fresno in the heart of Madera County, a region that spans from the flat San Joaquin Valley floor to the Sierra Nevada foothills. The city itself — served by ZIP codes 93636 (northwest Madera), 93637 (central and east Madera), and 93638 (south Madera near the Fresno County line) — is a mix of agricultural community roots and newer residential development. Summer temperatures in Madera regularly exceed 105°F, and PG&E bills for a typical 1,800–2,500 sq ft home run $250–$450 during peak months. The flat valley setting means most Madera roofs have unobstructed south-facing exposure — ideal for solar production. Madera County's permit office processes residential solar permits through the County Building Department, and Robbins Energy has navigated that process dozens of times for Madera homeowners.
FranklinWH aPower is a strong choice for Madera homeowners with existing solar who want the simplest battery retrofit path. Madera has a mix of solar inverter brands installed over the past 15 years; FranklinWH's AC coupling works with all of them without inverter replacement. For Madera County foothill communities (Oakhurst, Coarsegold, North Fork) with frequent PSPS events, FranklinWH's high continuous power output (10 kW) handles well pumps, larger AC systems, and other high-draw loads during outages. The stackable design means Madera homeowners can expand capacity as their needs grow.
Madera valley floor homes (93637, 93638) typically need one FranklinWH aPower for NEM 3.0 optimization. Madera Ranchos and foothill properties benefit from two units for PSPS backup coverage. Robbins Energy sizes based on your actual PG&E usage data and backup duration goals.
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. Suburban communities typically have newer housing stock with 200-amp panels and good solar access. Newer developments may have solar conduit pre-runs.
Permits issued by: Madera 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. Madera County permits process through the County Building Department. Robbins Energy handles the full process.
Suburban rooftops generally have good solar access. Newer homes often have 200-amp panels and may have solar conduit pre-runs. Mixed. Older west/downtown Madera homes often 100A. Newer east-side developments 200A-ready.

Most FranklinWH retrofits complete in 1–2 days once permits are approved. Robbins Energy assesses compatibility during the free site survey.
Under PG&E NEM 3.0, battery storage maximizes the value of your solar investment. Madera homeowners with high summer AC loads benefit significantly from evening battery discharge. In Madera, 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.
Summer grid stress and occasional PSPS events affect this area. Battery backup provides peace of mind and maximizes NEM 3.0 solar value. Low-moderate. PSPS events rare in city. Rural Madera County areas have higher outage frequency.
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.
