I have been doing a lot of research
for my first solar installation
and I have a few questions. I plan to use two Kyocera
and a Blue Sky SB3024iL MPPT
charge controller that can handle 12/24V. To minimize wire size I will connect the panels
in series and send 24V to the charge controller to charge our 12V house bank.
If the panels are rated 135W, 7.63A, and 17.7V, that gives me 270W in series. Is the maximum amperage to the controller 11.25A (270W / nominal 24V)? 24V at 11.25A on 10AWG at 3% loss gives me a maximum wire run of 38’ from panels to charge controller. Am I on the right track?
Initially, I plan to set the panels up on our dinghy’s cradle
while at anchor
then secure and store the stacked panels below the dinghy
while under way. I plan to use 10AWG marine
boat cable and would like to disconnect and stow the cable while under way. Is there a good marine
grade polarized quick-disconnect connecter I can use on 10AWG wire? Is a solar
panel with a junction box a more flexible solution on a boat than one with the new MC4 connector?
I have a power bus bar that I use to connect the house battery
bank to multiple charging
90A, and Xantrex 40A. I’ll also connect the Blue Sky SB3024iL’s output to the power bus bar and I’m adding a Xantrex echo-charger to keep the start battery
topped off. If the solar panels
, will there be any problem if I start the genset and the Iota
is on? How will the Iota or Blue Sky react if the other is also charging? Thanks for any insight.
