Frequently Asked Questions

AC chargers (typically 7-22 kW) use the EV's onboard charger to convert AC to DC for the battery. They are slower, cheaper, and ideal for residential, hotel, and workplace charging where dwell time is hours. DC fast chargers (60-800 kW) bypass the onboard charger and feed DC directly to the battery, enabling 20-40 minute charging — suited for highway, fleet, and commercial high-throughput sites.

Type 2 (IEC 62196-2) for AC, CCS2 + GB/T for DC, with CCS1 + CHAdeMO available on quote for North America and legacy Asian markets. Cable lengths 3.5 m / 5 m / 7.5 m. ISO 15118-2 plug-and-charge supported on all DC products; ISO 15118-20 V2G via firmware update late 2026.

All networked products support OCPP 1.6J and OCPP 2.0.1. Tested with ChargePoint, EVgo, Smappee, Driivz, EV.energy, Greenflux, Has·to·Be, Monta, AmpUp, Modo Energy. Custom CSMS integration supported for OEM customers.

Our 5-15 kW hybrid inverters support a wide range of LiFePO4 battery brands via standard CAN/RS485 protocols (BYD, Pylontech, Dyness, Hubble, FOX).
