I have a Torqueedo electric outboard with its own 800 watt LiSo4 battery and charge circuit. It will charge from a 12v bank that delivers 10 amps, and it will charge directly from 24v panels. The boat also has a 12v sump pump and running lights, that run off a 12v utility battery. I have 2 18v panels that put out about 3 amps each, wired in series. Is it possible to charge the 12v utility battery off the 24v system while the 24v system is charging the motor's internal battery at 12 v? I have a MorningStar Sunsaver 20 amp SS20L contoller, plus a variety of cheap Chinese 5- 10 amp contollers available. any thoughts would be appreciated.

In a word, yes. Whatever you connect in parallel will work more or less - how much current is delivered to each appliance depends on the active / passive resistance. Make sure the voltage regulator is working properly - 24V to charge a 12V battery is bordering on dangerous. Ideally it should not exceed 14.5v across the battery terminals.

I think you need to be careful here as different construction/types of battery need different types of chargers ,otherwise they could be damaged.
