Does your unit have 240 out, then a 6 circuit 2 watt meter transfer
panel is safest, you can see whats being used and balance it easily. A
complete prewired Generac transfer kit at lowes might be 2-300$ and take
2-4 hrs install, mine was free at lowes with a 5500w Generac Generator,
if it doesnt have 240 out call the manufacturer to see what they
recomend
