Following a recommendation, I opted for a Samil Solar River 4400 as part of my install  (http://www.navitron.org.uk/product_detail.php?proID=670&catID=128) - it's a competitively priced, highly efficient, nicely built piece of equipment that's better known in the Antipodes than here - I am just getting to grips with it's capabilities, and am very impressed - it could be ideal for many people, especially the "data freaks" - there is already Samil's V-iPlant (a much updated platform), which can be installed and run on iOS or Android devices to shovel the data online, and several Aussies are using PV bean counter

 "A new version of PV Bean Counter (1.8.3.13) is available here:
http://code.google.com/p/pvbeancounter/downloads/list
This version adds support for SAMIL (both RS232 and rs485) and KLNE (rs232) inverters.
This version also includes improvements relating to "Energy Today" at inverter startup, useful to owners of CMS inverters.
PVBC can query all serial inverters (CMS, SAMIL and KLNE) as frequently as every 6 seconds. These frequent energy readings provide live power readings on the PV Monitor gauges.
These readings can optionally be stored in the PVBC database at intervals between 6 seconds and 60 seconds. Regardless of these interval settings, PVBC will provide 5 or 10 minute energy readings for upload to PVOutput"

My first acquaintance with the data capabilities came when I received a "rar" file containing the Solar Browser, and some simple destructions - it was remarkably easy to implement - first of all I needed a relatively obscure USB/232 cable - a swift call to my local Maplins came up with this  - http://www.maplin.co.uk/usb-to-serial-9-pin-male-adaptor-29968 - so armed with it and a borrowed netbook running Windoze I approached the inverter with some trepidation.........

It was a total doddle - remove small placcy cover on the underside of the inverter, and offer up cable - doesn't fit because either side of the plug and socket are a couple of those "tall nuts" to allow things to be screwed in, so I decided that one pair had to go - the ones on the cable seemed very firmly attached, so I unscrewed the ones on the inverter and plugged in - clicked on the "solar browser" which immediately fired up - a few quick intuitive prods of "connect" etc had me looking at this -



-sadly the borrowed net book has only got a small screen so it doesn't show the whole thing  - up above that view are facilities to look at any faults, the set parameters, and with the appropriate password you can change the parameters (if you're an installer)

I've got the netbook for the rest of the week, so I'll post more details and screenshots in the next few days!

is that dual MPPT then?

also, has it / can it be set to limit the output to 16amps / 3680W or whatever you've got permission for? or are you just chancing it with the G83/1 limit?

and yeah, interesting grid voltage there...Wink

Single MPPT, and can be software limited to 3,680 watts/16 amps -  (can be left set higher for those with the appropriate consents!)

Well within limits , - I make 16 amps @ 257v  = 4112watts.

Hi Martin, a quick thank you for your help getting the Samil Power 'solarbrowser' software to work with my solar river 2300tl inverter. After some playing around with different notebooks the software recognised the software automatically and the information was there to view, albeit not in too much detail.

i have now connected the system to 'pv output', you can view the performance here http://pvoutput.org/list.jsp?id=11636&sid=9605. Pv output is fantastic and gives a more detailed view of how the system is working. It does however take a little time and patience to connect but once you have it going you can view online at any time and i have also downloaded an iphone app which gives me the same information.

i agree that the samil power inverter is a great purchase and thnaks again for your help.

Really pleased it worked for you - now all we need is some bloody sun to go with it! Grin

I have someone installing 3 of the 3000tl's and he cannot switch them on?? It says there is a "side switch" but cannot find any switches.
Is there a hidden switch or just turn on the DC and AC isolators. All 3 can't be faulty surely as they are just dead? AC and DC power present at the terminals.

I was under the impression they just fired up as soon as the DC flows from the panels (above 150 volts from memory) - if there's nowt coming from the panels it won't fire up!

So was I. About 260 volts DC but not a flicker. Guess they will go back whence they came on Monday.

If all three units are dead, it appears most likely that you have a wiring fault - it's far more likely that the chances of selecting three faulty inverters! Check you + and - connections - if they're the wrong way round, you'll get nothing.

Samil still rock! You are of course correct. I went down to check and took the voltage reading which was showing a decent voltage but with a minus sign! Of course the electrician had used branch connectors (as only one DC input) not realising that this would reverse the polarity. I had to change every MC4 connector. Didn't even get a drink.

Hi
I find it amazing and very worrying that inverters can be connected up without even basic voltage/polarity checks being carried out. On every circuit it is always standard practice to at least check the voltage/polarity on a live supply before connection.
