I've received a text from Vodaphone, (not my service provider,) warning me of possible power cuts and to get in touch if I have special needs in the absence of leccy. It's been ~50 years since I experienced a power cut in this part of the UK, so best I take the warning seriously methinks.
I've always had a plan to use a car battery, trickle charger, inverter and relay to keep the fan + filter going during a power outage but never got round to it.
The grow after this one will be 2 x HLG 100. Low enough wattage for a 450w inverter to power as well as the fan.
An inverter won't provide a perfect sine wave though. Will the HLG lights care about this? If not, I'll have the inverter power them. Otherwise, it will just power the fan.
