i was just in contact with Rod from ev-power. the the new bypass circuit boards are now bypassing at 3.5V. this solved one of the major disadvantages of the blue ev-power box.
at the moment i don't think i would trust the batrium any other than bypassing and having a visible interface of the cell voltages on a computer screen.
the old cell wires still keep on failing on my system. they either totally disconnect, having cold contact flickering or showing lower than real voltage. when a cell wire disconnects, the main board is nonoperational and would not disconnect the battery in an emergency. none of the new cell wires have disconnected so far. so there is hope for batrium.
compare this with the ev-power blue box, just plug in the data wires and connect the blue box and it works. super easy. but no monitoring and adjusting of cell bypassing voltages.

To date I haven't given wind turbine's much consideration. As a gentle breeze was about all we got is SEQ. Though after spending a year In my new location in SA with my weather station mounted around 5m height. I'm finding a considerable number of days have average wind speeds over the day of 40kph at times gusts of 80kph max. open paddock with a nice rolling hill that the shed sits on the high side.


So rather than getting P*** off when its blowing a SE gale all day and night. Perhaps I should put a + spin on the crap weather and at least get my house battery bank topped off over night. Or on a pea soup PV day as it usually coincides with a stiff wind.

Experimenting with a small 600w turbine next week. Rated at 600w at 39.6kph wind speed. Will report back when I get if its lives up to its ratings. I sure have the winds to support it. that said even a few hundred watts sustained overnight is a handy thing.

will be interesting to hear your results. and yes a combination solar and wind is excellent, as long as there is wind.

Interesting thread that has quite a few mentions of a Selectronic PS1 Inverter.
I have been fortunate (or not?) in having one given to me by a houseboat owner who has updated his complete system. Batteries, inverter, solar charger & generator.
There are quite a few settings that will need changing if I am to use it as a standby unit in my houseboat.
From the manual it says there are 2 lots of settings .......... one for the user & the other for the installer.
Does anyone have any info in regards to accessing the installers setup?
I connected it up & it appears ok except it is looking for the genny before it tries anything else
I see Kurt lives not far from me now days but isn't active here much lately.
Any info really appreciated.

OK, got into it OK and am now considering what I need to connect it to my laptop as it'll be much more comfortable programming it.
Hard to find the required cable though.
I'm guessing I won't get much help here ..... again?

bruceM,
you are not getting much help because the forum is not sending out emails anymore. for some reason.
maybe you should read the manual?
i am sure they have an online manual on the selectronics website.

Yes I've read the manual as well as the further in depth software connection instructions but as they are years old they talk about serial ports etc.
I can get a USB to serial cable.
I can get a null cable.
Having trouble finding a PS1 serial cable.
The last cable has an 'ordinary' network plug on one end and a serial connector on the other.
I'm sure I could construct a cable to replace all 3 cables. I'm thinking either Selectronic or another user has already done it?
Where I intend using the inverter it would almost be impossible to use the onboard LCD screen.
I'm thinking pinout info MUST be out there somewhere?
EDIT: found it I think.
