WM-DC3
WM-DC3: Smart Modular Setup
What truly sets this system apart is its unique stackable modular design: you only get and pay for exactly what you need. Because the AC box and DC CCS charging box are supplied externally, they stay on-site and do not need to be transported back and forth with every battery swap—saving you unnecessary logistics and costs.
