Re: Stus-List Solar Charge Controllers, Battery Chargers and Battery Equalization

[Josh Muckley via CnC-List]

Equalization is not a problem as long as you water the batteries before and
more importantly AFTER each cycle.  There is a point of diminishing returns
regarding equalizing but I'm not sure there is a point of damage beyond
boiling dry.

Stus-List Solar Charge Controllers, Battery Chargers and Battery Equalization

[Bruce Whitmore via CnC-List]

Hello all,
A couple months ago, I installed 380 watts of solar power with a MPPT charge 
controller.  The solar controller is Renogy Rover 40 AMP unit.  I also have a 
couple "smart chargers", one for each bank, both of them are ProMariner 
ProSport models.  

Both the chargers and the MPPT controller have battery equalization modes, and 
I don't think there is a way to get the ProSport charger to NOT go into 
equalization mode unless I change it to Gel Cell mode, which is not appropriate 
for my flooded lead acid batteries.  There is also no real information in the 
manual as to the equalization parameters of the ProSport charger. 

So until I can find a way to program the MPPT controller (which is currenly a 
challenge due to issues regarding getting the appropriate cable to connect it 
to my PC), how big a deal is it that I would end up with two equalization 
cycles happening per month?
Thanks!

Re: Stus-List Solar charge controllers

[Stevan Plavsa via CnC-List]

Yes.
With the boat, the sky is the limit for spending. Ask yourself, do you
really need "the best" for your solar setup? Good panels are a must, they
last a long time. With all due respect to "Maine Sail" (I've donated money
to the guy because his site is so damn helpful), his article about cheap
chinese controllers is years old. Again: "commodity" tech, this stuff just
gets better and cheaper. The beauty is that if the cheap chinese thing
doesn't work out you aren't out much, but the reality is that it will work
just fine.

Having a built in display is more useful to me, personally, than knowing I
have "the best" and a 10% efficiency gain. I don't care. My batteries stay
topped up when I'm not on board, that's the point (for me).

Copied and pasted from the Maine Sailor review conclusion:

*"Best Value In A High Performance MPPT Controller = Genasun GV-10"*

I would suggest you call Genasun directly and talk to them about what 
you need. They are very helpful, and in fact, the founder is a long 
distance sailor who was inspired to design a bullet proof controller 
after a personal bad experience. Read the "about us" page on their website.


"Alex MeVay, Genasun’s founder, was sailing the Yucatan in 2003 when his 
power went out. An industry leader’s PWM solar charge controller had 
failed somewhere between Guadeloupe and Boston, leaving him stalled in 
the open ocean to fend for himself. MeVay disassembled the controller to 
find poorly designed electronics and more cut corners than he could 
count. And though he had spares available, he was unnerved having bet 
his life on a shoddy solar component.


After returning to the USA, MeVay joined the MIT solar car team, where 
he spent the next three years refining leading-edge design of solar 
charge controllers and lithium batteries, and designing what would later 
be Genasun’s first MPPT controller. And thus, a new day in solar power 
began."

Thanks guys, I had been focused on getting a Genasun.  I was gonna do 2,
one for each 100w panel.  I had hoped to use their 5amp unit but in
reviewing the specs it looks like I would exceed the ratings by a small
margin.  I looked at the 10amp unit but it is nearly twice the price.  If
they made a 15amp unit then I could justify it since I would only need
one.  Maine Sailor on pbase had some observations about the Genasun units
and was not particularly impressed.  He cautioned against the cheap Chinese
controllers and provided a list of recommended companies.  This led me to
the MorningstarStar 15 amp MPPT.   I liked the control options and
customizations.  I liked the optional remote display panel.  The price for
the whole package would have been twice that of 2 Genasun 10 amps.  Then I
looked at the Victron BlueSolar.  A single unit would cover 20amps at the
same price as a single Genasun 10 amp.  I was close to purchase but then
realized I would miss out on the customizations and controls of the
Morningstar unit.  I was also cautioned that the Victron unit might need at

Many cheapo controllers say MPPT but do not actually contain the

USA, and you can talk to the MIT educated engineers in Cambridge 
Massachusetts should the need arise.

Re: Stus-List Solar charge controllers

[Marek Dziedzic via CnC-List]

If you want a good one, get a Genesis controller. They are not cheap, but 
they’re not expensive and they are good. I think they are a bit cheaper than 
Morningstar.

You want a good one. You can easily murder the batteries with a poor one.

I have a Morningstar duo and I am happy, but if I were to do it again, I would 
buy a Genasun.

Re: Stus-List Solar charge controllers

It's hit or miss. I purchased my solar panel and controller as a kit from
an ebay store located in Quebec. This outfit:
http://www.ebay.com/usr/solar-power-canada?_trksid=p2047675.l2559

If I were cruising full time I wouldn't cheap out on this. The truth is
that I'm a weekend cruiser and this technology is a commodity. Three
seasons now and I don't regret cheaping out on this one, the kit has served
very well.

I think Renology sells cheap Chinese solar panels (some of which are 
manufacturing rejects from name brand companies).  Apparently, they are selling 
a cheap voltage controller now.  With something like this, it may work out fine 
for you or it may not.

Re: Stus-List Solar charge controllers

[Robert Boyer via CnC-List]

Josh:

You might want to consider some redundancy in voltage controllers, not having 
all your solar panels go thru one voltage controller.  The voltage controller 
is the most likely piece of the system to fail--certainly more likely than the 
solar panels.

Look for ones with lots of reviews and read them.  Many say MPPT but are
not. Ones with lots of reviews often have a skilled person test its MPPT
functionality.

Hey guys,

Anyone have a good experience with an ebay or Amazon, el cheapo solar
charge controller.  Particularly a MPPT type.  The price for the
Morningstar is just a little prohibitive for what you get.

Renogy Traker MPPT 20A with the accessory meter is cheaper than just the
Morningstar 15A, MPPT ootion.  It is also only a little more expensive than
the Victron BlueSolar 20A MPPT version.

Thanks,
