Hi.
I have 3 x lead acid batteries, 500a smart shunt, a100/50 mppt. And 600w solar.
The shunt shows over90% soc, but only 11.8v in battery. Is this normal?( batteries are new)
Thanks

Thank you for your response.
I will check shunt settings, but I think it may be the overnight load . I have a fridge freezer and also need to check the load drain of the 3kw inverter. The batts have dropped from 11.93 to 11.5 overnight so not terrible. Thanks again, and enjoy the boat!
