  • Page 24 SMA Solar Technology AG Electrical Connection Cable Protection In addition to the thermal fuses in the charge controller, install a separate fuse as close to the battery as possible. Install a suitable fuse according to the maximum specified DC currents. You can, for example, install a 63 A line circuit breaker.

  • Page 25: Communication

    If the LED does not illuminate, the poles of the DC cables are reversed and the thermal fuses must be replaced. If this is not the case, the charge controller is defective and must be replaced. In this case, contact the SMA Service Line. See section 14 "Contact" (Page 47).
