Re: Complex design issues
I'm using Victron MPT 150/35 charge controllers on each of my 3 panels that are in series and it has no issue evening out the voltage.? It has a rotary switch that lets you set the charge profile

Re: Complex design issues
Yes, I've been thinking about that, in that the panels are rated at 12
volts but on a sunny day, they roll out an average of 18 volts. That's the
dilemma. With each panel putting out 18 volts, I'll

Re: Complex design issues
“?I have 8 100watt/12 volt panels ……”
I have seen some 100 Watt panels advertised as 12V, but most actually put out somewhere between 21 and 26 “open Volts” (just measured with a meter

Re: Complex design issues
NP Dale good luck with the set up.? I'd recommend trying different locations/angles and measuring the output voltage/current to see what works best.
Other than the efficiency I find that using

Re: When the ideal house voltage please stand up?
I think it wise to always have a separate 12V system for your instruments, running lights, and communications along with at least one stone age lead acid (or AGM) battery to power it with. And know

Thanks Jeff. I have 8 100watt/12 volt panels and am considering
parallel/series them to have 4 sets of two panels in parallel and then
those four sets set together in series to give me 48 volts and up

Re: When the ideal house voltage please stand up?
Thank you for your replies. I understand the relationship between battery motor and generator. Getting back to my question. Why would it be harmful to wire the boat with 120 ac? What disadvantages

Re: Complex design issues
LEAD IS DEAD! LiFePo is an acceptable chemistry for marine applications.? Stay away from anything with cobalt in it and you'll be fine.?

Re: When the ideal house voltage please stand up?
I am now even more confused.
what voltage is the battery? What capacity?
Describe the motor, brand, type, size. Is it an AC or dc motor? How will you control its speed?
describe the motor drive:

There is no such thing as 120 volt AC house Bank. Batteries are only Direct

You really don't want to use the wrong type of wiring or connectors, and
you need proper fuses...
