Solar Panels and Thruster Charging

[Alibi27]

Do the solar panels automatically also charge the thruster battery if it is low ( 12.4 v).
The yard installed 4 new batteries this spring. LifeLIne100 ahr not the Universal 110 ahr I requested.
Sitting at anchor for several days with good sun, mostly only the frig running.
At the end of the day should all three battery sets ( engine, house, thruster) be at roughly the same voltage.
Is there a wiring diagram from the solar panels.
2013 Ranger 27 bought used. FMLT2723B313. One of first 27 models switching to Volvo.

yes they should all be connected by the Blueseas ACR so as long as the voltage is high enough all batts should get charged.

On my 2020 R29S, I was told and the manual confirms, that 90% of the solar cell output is directed to charging House batteries, and 10% to Engine battery. No solar power is charging the thruster battery. I can adjust those percentages on my solar panel controller.

Keep in mind that the leads from the solar are connected to the house and engine as you state, but the relays, when functioning correctly, join all the batteries together at specific points.

Yes, the relay combiners will latch starting to house and house to thruster. I’ve killed my thruster a couple of times before discovering the ACR drops out at 10.5 on either side. I paralleled Yandinas, which don’t have that safety feature...
