Gas/Propane Generator.
I have a 4kw Wen on standby for situations like this.
Unless you want to spend thousands on a lifepo generator, there isn't much you can use on a reef tank to last the night / few hours.
Of course if you live in a condo where your neighbors/Hoa will raise hell from the noise a gas generator makes, the LifePo generator maybe your only option.
Id get at least a 6KWh unit depending on how large your reef tank is.
If its a small one, and heater isn't important i guess you can get by with a 2kwh unit.
But remember heaters are the biggest power hogs, as you can just run lights off during the black out.
