Fair enough.

Naturally, if you're looking at multi-day outages, then you'll likely 
reduce your load quite substantially for the period, allowing you to 
keep the battery running until the following morning when the sun comes up.

But yes, in your situation, a multi-day outage would not be that 
different from an off-grid self-generation scenario; in which case, a 
generator is necessary to recharge batteries, particularly on cloudy days.

Mark.
