Like many businesses and homeowners across the UK, a commercial property in Wigan, Greater Manchester, felt the pressure of rising energy costs. In search of a long-term solution, the owners sought to reduce operating costs and improve energy resilience by investing in a renewable energy system.
ASK Renewables Solutions was contracted to install a three-phase battery storage system. The business had previously relied on grid energy to provide the building’s power, so a shift to harnessing renewable energy with a HANCHU battery storage system was a strategic move to protect profits and reduce grid reliance.
ASK Renewable Solutions designed a commercial-scale system, combining a large PV array with a HANCHU ESS battery storage solution. The system, a 50kW C&I three-phase hybrid inverter with a stack of HANCHU ESS 9.4kWh high voltage batteries, totalled a storage capacity of 28.2kWh. The system now supports heavy loads, whilst storing excess energy for use during non-generating hours.
Between January 24th and May 1st, 2025, the property consumed 24,800 kWh of electricity, which would have cost £7,192 at a rate of 29p per unit. During the same period, the solar panels generated 16,100 kWh of electricity, out of which 14,000 kWh was used and stored in batteries (for later use), resulting in a savings of £4,060. The remaining 2,100 kWh was exported to the grid, earning £315 at a rate of 15p per unit. In total, the owners effectively saved £4,375 over approximately three months.
The client now benefits from significantly reduced energy bills, greater grid independence, and future-proofed infrastructure ready for EV integration or system expansion.
