If that panel doesn't list your breakers on the specifications sheet then your panel cannot use them in it.
There is also chance that your existing panel can have an interlock kit and backfed breaker installed just like the one your looking at only you will not have the watt meters. For considerably less money. There are aftermarket kits and the panel manufacturer may offer an accessory interlock kit.
