I have just installed a 130W solar
panel on my boat
. I usually plug
in the boat
at the dock
and have the truecharge 40 at all times to keep the batteries
top up. The solar
charge controller is a blue sky MPPT
I have a link 2000 with a dual shunt with one side set up to monitor
the solar/wind setup. I can see that even though I am on shore power
with the charger
, the solar system still provides a bit of power. Sometimes the solar charge controller will show a bulk charge as opposed to float.
Is it possible that the MPPT
float voltage is slightly higher than by battery charger
and it gives it a bit more during the day?
Is there a problem with having shore power
on at all times with a solar panel?
Just want to make sure I'm not going to ruin a part of my charging
system by running both systems.
