Perhaps also useful would be plug in batteries, especially if one has variable rates. Charge when cheap, discharge when expensive.
One constraint on these I've read is that if you have sources and sinks on the same circuit, you might overload the line without tripping the breaker at the box. If I'm understanding this correctly this has caused them to limit the power of plug-in solar to a fraction of what a single circuit could potentially carry.
