Can the Apex 300 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 Apex 300 has a 3,840 W output (no surge rating is listed). 1/3 hp furnace fan (EWEB figure): likely, though no surge rating is listed; check with BLUETTI; 1/3 hp furnace fan (Honda figure): likely, though no surge rating is listed; check with BLUETTI; 1/2 hp furnace fan: likely, though no surge rating is listed; check with BLUETTI.
How much an hour takes
An hour of a 1/3 hp furnace fan (Honda figure) running nonstop uses about 1,000 Wh, about 43% of the Apex 300’s usable 2,350 Wh. At its 2,400 W solar input and our 75% assumption, strong sun puts about 1,800 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.
