Frequently Asked Questions

Q: What is the expected payback period for a GCB-E50 in a peak-shaving application?

Payback depends on the local tariff structure — specifically the peak-to-off-peak price spread and demand charge rate. In markets with demand charges above $10/kW/month and peak rates 2–3× off-peak, typical payback is 3–5 years. The 6,000+ cycle life at 90% DOD ensures the system remains economically productive for 15+ years before significant capacity fade. We can model your specific tariff and load profile for a project-specific ROI analysis.

Q: Can the GCB-E50 operate fully off-grid with solar?

Yes. The GCB-E50's hybrid inverter supports grid-tied, off-grid, and hybrid (solar-plus-storage with grid-fallback) modes. In off-grid configuration, the system powers critical loads with seamless transfer — no interruption during grid outage. Solar PV can be AC-coupled through the inverter. The applicable mode, solar array sizing, and protection coordination must be validated for your specific site and local grid code. All modes are configurable — not locked to a single topology.

Q: What customization options are available for the GCB-E50?

The GCB-E50 is fully configurable to project requirements. Customization options subject to project volume include: inverter platform selection (Deye or equivalent), cabinet color and OEM branding (logo + housing), communication protocol (Modbus TCP/RTU, CAN, IEC 61850), cell capacity selection, and destination-market certification packages. Contact us with your project specification for a customized proposal — engineering response within 2–3 business days.

Q: What site preparations are needed before GCB-E50 installation?

Pre-installation requirements: (1) Level concrete pad or indoor floor with adequate load-bearing (~650kg + safety factor), (2) Minimum clearances — 1m front and rear for service access per local electrical code, (3) AC cable routing from the main distribution panel to the cabinet location, (4) Communication — Ethernet cable for remote monitoring (4G optional), (5) Environmental — ambient temperature within -20 to +55 °C, protected from direct flooding. We provides a detailed site preparation guide and remote commissioning support. On-site engineer available for projects above 500 kWh.
