I worked a US night-shift corporate job for three years while living in Manila, and it was totally doable year-round as long as you pick the right building and have a simple backup plan. In Makati I had 500Mbps PLDT fiber, and later in Eastwood 300Mbps Red Fiber. Both were solid most of the time. The internet only went down twice in three years, but when it did, it stayed down for about a week, because local ISPs don't fix things quickly. Instead of stressing, I booked an emergency Airbnb in another area and worked from there until it was fixed. You definitely don't need to spend money on huge power stations or Starlink. What really matters is checking the building's backup power before you sign a lease. My place in Makati only backed up 20 percent of the building plus one outlet for the fridge, while my place in Eastwood backed up the entire building. Starlink is a non-starter anyway, because condo balconies only give you a tiny slice of sky, so the signal keeps dropping. If you're trying to stay under your employer's radar, spend that money on proper network privacy instead. I put StarVPN residential on a GL.iNet GL BE3600 router and it worked great. Make sure you turn on the kill switch; it saved me a few times when the VPN dropped out of nowhere. As for typhoon season, it never really affected my work. Storms and heavy rain never knocked out power or internet in either condo, so there was no real reason to leave the country during those months
