Hello
I would like to upgrade my boat and would like to buy a solar panel
I decide to buy a LG solar mono panel 350w for my boat
on my boat i have 2 bateries, maybe i would like to buy one more
they are all AGM
Now i am looking for a Smartsolar
but i dont now the size to buy or witch model ?
Can you please help me
Regards
I'm going tro assume that your batteries are 12V, your system Voltage is 12V.
So, with 350W of PV power, you'll be charging with around the same power.
350W / 12V = 29.2A
You need a charge controller that can charge at 30A to be able to make the most of your solar panel.
The MPPT100/30 will be perfect for you. This charge controller's output will be maximised with 350W of solar on a sunny day.
If you have even the slightest idea of adding more panels in the future, then you'd be better off considering a larger charge controller.
Thank you for your help
i can put only one panel on the boat
the system is 12V
can i charge only one batterie or i can charge all 2 or 3 maybe in the future
Regards
Im curious what would happen if I use a 75 / 15 instead? Will it just limit the current flow or will I damage the unit?
i have a lg 350w panel 2 of them. Both are hooked to their own 100/30 smart solars without any troubles. I cary a third smart solar onboard my boat in the event of a unit failure.
