How much battery does a 120 kW DC hub need?
Depends on simultaneous vehicles, utility demand limits, and solar kW. Share port count, hours of operation, and tariff—we model kWh and charger series together.
Solution Detail
Solar + Storage + EV Charging
Integrated PV, LFP storage, and Osiwei AC/DC charging—from 7 kW home chargers to 240 kW+ hubs and mobile storage—so fleet, retail, and property owners fund one coordinated export scope.
Recommended approach
- 1Map parking count, dwell time, and target kW per port (AC 7–22 kW vs DC 30–240 kW+).
- 2Size PV and LFP to shave peaks, absorb midday solar, and support OCPP-managed load balancing (DLB).
- 3Select charger series by standard (CCS, GB/T, NACS, Type 2) and environment (IP54 wall, IP65 liquid-cooled, mobile ESS).

Solution FAQ
Can chargers work without solar on day one?
Yes. Many sites stage AC/DC chargers first and add PV+ESS when permits close—note phased timeline so wiring and switchgear stay storage-ready.
Do you support V2G or mobile charging?
Osiwei catalogue includes V2G, V2V, robot, and mobile DC lines. Describe use case (fleet depot vs public hub) for the right series and certification path.
