LG RESU Prime in Dunlap
The LG RESU Prime is a compact 16 kWh LFP battery designed for residential retrofit installations. It pairs with compatible hybrid inverters and is known for its compact form factor — ideal for homes with limited installation space.
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.
