One could use something like this for a hybrid "grid tie" solar system. (Not really grid "tie" because the switch keeps the solar and grid isolated from each other, but the system can switch back and forth). The transfer switch is automatic and can be controlled by an appliance timer so nothing is draining your battery when the sun isn't out.
Basically, it allows one to use electricity as its generated, no reason to store it for later, no expensive battery banks, no permits, and no permission from helco.

" Product description
Go Power! 30 Amp Transfer Switch is used to hardwire inverters into a system where there is an alternative source of AC. This transfer switch is made to only allow one source of AC power to pass through it to the loads and can handle 30 Amps of service. This ensures that the inverter will not be damaged if the generator or utility power is hooked up while the inverter is running as well as well as contains all instructions."
