Crawley 15kWh Battery Install

This client wanted a compact, efficient system that would reduce energy bills and provide long-term performance. We installed a 15kWh storage setup using a single 15.36 kWh ZT-one Powerwall battery, paired with a 5.5kW SunSynk Hybrid Inverter to ensure smooth energy management and strong daily cycling capability. The result: a streamlined, high-efficiency installation delivering an estimated £43,858 lifetime net saving and a projected payback period of 5 years 4 months.
