Wh × 0.85 ÷ (watts + the station’s own draw, where the maker lists it).

Hours are nonstop; the fan cycles with the thermostat, so real hours are longer.

Can the AC180 start it?

Honda lists 1,800 W to start a 1/3 hp furnace fan and 2,500 W for 1/2 hp (Honda); EWEB’s chart gives about 2,100 W for 1/3 hp (EWEB). The AC180 has a 2,700 W surge. 1/3 hp furnace fan (EWEB figure): covers it; 1/3 hp furnace fan (Honda figure): covers it; 1/2 hp furnace fan: covers it.

How much an hour takes

An hour of a 1/3 hp furnace fan (Honda figure) running nonstop uses about 1,000 Wh, more than the 979 Wh the AC180 can deliver, so it runs about 58 min. At its 500 W solar input and our 75% assumption, strong sun puts about 375 Wh an hour back into the battery.

A furnace wired into the panel needs a transfer switch installed by a professional; never connect a backup to house wiring yourself.
