The Sol-Ark 15K is a 15 kW all-in-one hybrid inverter that combines a solar charge controller, battery inverter, and grid-tie inverter in a single unit. It supports lithium and lead-acid batteries, works with most battery brands, and is popular for off-grid, grid-tied, and backup-critical applications in rural Central Valley communities.
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.
Sol-Ark 15K is one of the most capable hybrid inverters for mountain properties seeking off-grid or near-off-grid operation. It handles generator integration, battery charging from multiple sources, and complex load management. Shaver Lake, Big Creek, Lakeshore, and Hume are strong Sol-Ark markets.
Mountain off-grid or near-off-grid systems typically pair Sol-Ark 15K with 40–80 kWh of battery storage for multi-day autonomy.
Built-in MPPT charge controller handles solar input directly. Compatible with most residential solar panel arrays.
Whole-home backup is standard. Seamless transfer during outages. Configurable for off-grid operation.
Requires 200A panel for whole-home backup. Robbins Energy handles panel upgrades as needed. 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. Hybrid inverter installations require building permits and PG&E interconnection approval. Rural county permit timelines vary — Robbins Energy manages the full process. 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.
