Only if you have battery storage.

  My system does not have battery storage. A storage battery would be considerably better in the event of a power outage, but also would have doubled the cost of the system. My plan is to have another look at batteries when it is time to replace the inverter, and hopefully the cost per kWh will have dropped by then to the point where batteries make more financial sense.

  That’s mostly true, but not entirely. SMA (inverter) offers Secure Power Supply on some models, which give you a single 120 Vac outlet that can provide up to 2 kW (about 15 A) assuming there is enough sunlight. If the solar panels are producing less, it can still provide lower amounts of power. For things like charging phones, a small TV, laptop, modem, and router, it should give you power during most daylight hours, regardless of cloud cover, if you have a 6 kWdc array.
