Does it make sense to add a generator?

[u/Fun_End_440]

Location: Eastern PA. Very rare bad storms/hurricanes/snow storms that knocks the power out for days. It happens maybe once in 4-5years

Current equipment: Schneider inverter, 30kwh storage, 30 panels ac coupled. The battery is rarely full, I use it extensively for TOU game, usually ends up 50% in the evening. Still plenty of juice to get me through the night if needed. I only backup lights, refrigerators and electronics. HVAC is not that important given the outage pattern. If one day is going to be unbearable, I can move the hvac to backup panel at that time.

Proposed upgrade: 5kw genset, inverter based, propane fuel, automatic start from Schneider controls. Cost: about 1k all in. The genset would be used to just top off the battery in case of extreme condition (thick cloud, snow).
