Q1: Do Purebus energy systems comply with international electrical and safety standards?
A1: Yes. All systems meet relevant IEC/CE/UN38.3 safety and EMC standards. Components undergo extensive testing for electrical protection, fire safety, and environmental durability (e.g., IP54/IP66 rated enclosures).
Q2: Can you provide customized configurations (e.g., capacity, voltage, communication)?
A2: Yes. Custom options include battery capacity (up to 280Ah/module), nominal voltage (LV 51.2V or HV 135-750V), and communication protocols (CAN, RS485, Wi-Fi, Ethernet). Both modular and rack-mounted systems are available.
Q3: What is the lead time for delivery?
A3: Standard products can be shipped within 7-10 working days. For customized models or large quantities, lead time is typically 20-30 days. Expedited orders and scheduled production are available upon request.
Q4: Do you support third-party inspections?
A4: Yes. Purebus welcomes third-party inspections from SGS, TUV, or client-assigned agents. Full test reports and compliance certificates are provided before shipment.
Q5: Are systems compatible with other inverter brands?
A5: Yes. Energy storage systems support open protocols (CAN/RS485) and can be integrated with a wide range of inverter brands. Configuration tools and wiring diagrams are provided for seamless setup.
