During a power failure, the battery can provide a maximum of 1.5 kW for the S10 MINI, up to 6 kW (depending on model) for the S10 E, S10 E COMPACT and S10 X COMPACT and up to 9 kW for the S10 E PRO. If the E3/DC inverter kicks in while the emergency power is in operation, due to the PV system producing power, the output power can be increased to 4.6 kW for the S10 MINI and 12 kW for the S10 E. As soon as the fault has been resolved, the S10 switches back to normal operation.
One advantage of the E3/DC’s unique technology is that no additional switch boxes or switching units are required for emergency power operation. For the three-phase backup power in the S10 E, S10 E COMPACT, S10 X COMPACT or the S10 E PRO, only a motor switch is required, subject to an additional cost. It is installed in the factory, according to the order, or it can be fitted later.
