Electrical Power Recharging Options for Extended Cruise
Gererators are a viable alternative. I would like to point out that your 55 Amp alternator is not really high output by today''s standards. You might consider upgrading to a a 100 to 150 amp alternator. This would should cut your charge time by half. You will probably never end up with 100% charge for the reasons you already know but most people find 85% sufficient.
