40kW Skid Mounted Solar PV Based EV Charging Station 80kWh LFP Battery Storage

The 40kW solar battery charging station is a skid-integrated solution for fleets that need medium-speed DC charging combined with daytime solar self-consumption. An 80kWh LFP battery bank absorbs excess PV energy and discharges during vehicle return windows, flattening demand peaks that would otherwise trip site feeders.

• 40kW dual-gun DC output with dynamic power sharing
• 80kWh rack-mounted LFP storage with optional liquid cooling
• Skid frame delivered as a single lift unit to reduce on-site work
• Air-conditioned cabinet keeps electronics below 35°C
• Touch HMI displaying revenue, session logs, and alarm history

Parallel DC power modules feed a common DC bus that also connects the battery and PV array through MPPT trackers. The energy management algorithm schedules charging against solar forecasts, tariff signals, and fleet return times. All contactors and fuses are electronically interlocked.

Designed for delivery van depots, ride-hailing parking hubs, bus terminal auxiliary charging, and logistics warehouses with solar roofs.

• Single-lift design reduces civil works and commissioning time
• Peak shaving protects the existing grid connection
• Power sharing between guns improves utilization
• Air conditioning extends electronics life in hot climates

We provide skid assembly supervision, control logic tuning, a two-year module warranty, and a five-year frame warranty. Remote alarms reach operators via SMS and a cloud dashboard.

Incoming cells are capacity-graded and sorted before assembly. Each skid undergoes a factory acceptance test (FAT) with simulated vehicle load, and the control cabinet is wired to IEC standards with clearly labeled terminals.
