Installing Battery Cables (Only for UPS with Long Backup Time)
1. A UPS with long backup time is connected to external battery strings. Each battery string
consists of 16 to 20 batteries (16 by default, configurable).
2. Install a DC circuit breaker between a battery string and the UPS with long backup time.
Install a 50 A 300 V DC circuit breaker for the 6 kVA model, and a 63 A 300 V DC circuit
breaker for the 10 kVA model.
3. One or two battery boxes can be connected. For details, see the ESS-240V12-2x(9AhBPVBA,
7AhBPVBA) Quick installation Guide. If longer backup time is required, choose a battery rack.
