Grid-Scale Storage & Microgrids — 230V three-phase units for utility-scale storage projects where thermal reliability is non-negotiable.
FAQ
Q: What cooling capacity do I need for my BESS container?
A: Container cooling demand depends on battery capacity, ambient temperature, and charge/discharge rate. Our engineers provide free sizing support send your container dimensions and battery specs for a recommendation.
Q: Can this unit run in extreme outdoor temperatures?
A: Yes. The ACC3026W operates reliably from -40°C to +55°C with IP56 sealed construction, tested for desert heat, coastal humidity, and Arctic cold.
Q: Is remote monitoring supported?
A: Standard RS485 Modbus with auto-restart and 8 alarm types. We can also configure custom alarm protocols for your monitoring platform.
