Multiplus and power supply in parallel

hi,


I have a 12v 800Ah LFP battery bank I charge shore power with a multiplus 12/3000 on board my boat. I want to increase the charging capacity with with an extra shore connection. The natural choice would be to buy an extra multiplus, but these are not exactly cheap. So here's my question ... can I use a 100-150A power supply in parallel with my multiplus up to eg 70-90% SOC and top up to 100% using only the multiplus? Good or a really bad idea?

That seems reasonable, multiple charging sources are perfectly acceptable.
Being a power supply, of course you'll need to ensure that it does not over charge the battery.
