Alex,
With some modern MPPT controllers series is
more efficient. I only had enough room at the top of the
EMEK Marine arch for three of the 135 watt panels. They are
wired in series producing a maximum of 75 volts to the
controller, and my controller takes a maximum of 75
volts.
While at anchor, I run the generator to make
water, to heat water, to wash clothes, and to top off the
batteries.

Thank yo so much Bill,



So 3 x 135 Watt sola panel is enough !

That sounds great. I thought I would need twice the amount.


So you have regular “flooded” Delco Freedom batteries
and they charge fully, this si great.



I thought of the Kyocera as well.

Are they mounted on series or parallel?



A neighbor on a 54 has 4 x 200 Watt mounted in series and
obtain 96 Volt which is then convert in 24 volt…

he (try to) explain the lost of energy proportional to the
square of the amp, etc. in short gaining 35% by mounting in
series, but I have absolutely no clue on that…

So just trying to understand and see working solutions…




Why do you run your genset? To make water, etc. or also to
help charging the bateries?



As always thanks for the help!

Sincerely, Alexandre

Alex,

We have 405 watts of solar which will keep the

batteries at 100% during daylight while running freezer,

fridge, fans and a computer or two.  We have a Victron
Blue

MPPT controller which has been very good at regulating
the

charge during daylight hours. We have 12 standard 110amp

house batteries...freedom model.

I would go with either German or Japanese solar

panels and keep clear of Chinese. There are probably
good

panels from China, but I know that there are many poor

quality panels. I think that you get what you pay for. I

chose Kyocera panels from Japan...3 @ 135 watts each with
a

MPPT controller up to 75 volts and up to 50 amps. I have
the

3 panels wired in a series.

I now run the generator at anchor for about 1

to 1.5 hours every second day.

Good morning,







Currently I have 8 of the traditional deep cycle flooded

batteries, which is ok, since I spend a large amount of
time

in Marinas because of my work.







Therefore, I might start to spend more time at anchor.



From sailing experience I know the genset doesn’t
fully

charge the batteries.



So will consider solar panels.



Does anyone have input in this solution?



Also for those using solar panels, did you keep the same

flooded batteries or did you change them with AGM, or else?










Thanks in advance, sincerely, Alexandre
