Sol-Ark 15K in Dunlap
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.
Dunlap is a foothill community in eastern Fresno County, located at approximately 2,400 feet elevation near Kings Canyon National Park, served by ZIP code 93621. The community is a mix of single-family homes and rural properties with excellent solar exposure — the elevation provides cooler temperatures than the valley floor, which improves panel efficiency and extends the productive hours of your system. Summer temperatures typically run 90–100°F, and PG&E bills for a typical Dunlap home run $180–$340 during summer months. PSPS outages are frequent during fire weather season due to Dunlap's proximity to Kings Canyon National Park transmission infrastructure. Many Dunlap properties have well pumps — during a PSPS event, a home without battery backup loses both power and water.
For valley homeowners in Fresno and Clovis replacing an aging string inverter, Sol-Ark 15K is a compelling all-in-one upgrade — new inverter plus battery capability in a single installation. Particularly strong for larger homes with high summer AC loads.
