Source: Longlight Energy Published: 2026-07-16 Views: 226

Project Overview
A mixed-use commercial block combines roof PV, parallel Longlight-INV6 inverters and Longlight-304 18kWh cabinet storage to stabilize daytime operations and protect POS / IT systems after dark.
Customer Challenge
Peak AC demand from HVAC and elevators exceeded single-inverter limits. Management also required longer backup for servers, CCTV and payment terminals.
Longlight Solution
Longlight-INV6 units run in parallel with dual MPPT fed by 550W high-power modules. Cabinet LiFePO4 ESS supplies evening peak shaving and UPS-like support for critical circuits.
System Architecture
- High-power PV array (550W modules) on large roof
- Parallel Longlight-INV6 hybrid cluster
- Longlight-304 cabinet ESS with App SOC monitoring
- Critical bus for IT / POS / security
