LG RESU Prime in Fresno
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.
Fresno is the largest city in the Central Valley and one of the most solar-productive locations in the entire state. With summer temperatures routinely exceeding 105°F and PG&E electricity rates among the highest in California, the financial case for solar in Fresno is straightforward: your air conditioner runs hard from May through September, your bills spike to $300–$500 per month, and a properly sized solar system eliminates most of that cost. Fresno homeowners across all 20 ZIP codes — from the older neighborhoods near downtown (93701, 93702, 93703) to the newer developments in northeast Fresno (93720, 93730) — are making the switch to solar at a rapid pace. The city's flat valley floor means most roofs have excellent south or west-facing exposure with minimal shading, and the 300+ annual sunny days ensure your system produces near its rated output year-round.
