Solar 1kw Installation; Inverter Rs232port

Q: Many people (like myself) are installing 1kw grid tie inverter systems to take advantage of rebate system. I am happy with it except the solar installer doesnt have technical knowledge about interfacing to the rs232 port on the inverter for data logging etc. The inverter is a generic rebadged brand so cant contact manufacturer. cms-2000 http://www.aussiesolar.com.au/inverter_CMS-2000.pdf I am wondering if anyone has played with the serial port of their grid tie. What baud rate? Can you use hyperterminal that comes with xp. What command do you send to it?

A: I suspect that the manufacturer may be Phoenixtec. They claim to be the leading UPS maker in Taiwan. In fact if you search for phrases from the CMS manual, you will find Phoenixtec Sunville manuals with the same phrases, especially in the troubleshooting section, and with the same typos and identical Chinglish. See the indoor unit on page 3 of this brochure: http://www.phoenixtec.com.tw/solar/files/CONTENT(20080702).pdf Here is a brochure for their EZ logger: http://www.euronet-group.cz/pdf/accessories.pdf The CMS-2000 could be a Phoenixtec indoor model PV-2000X or similar. Its a disgrace what the goverment is doing. Giving $8k to families who earn under $100k so they can put in 1kw is absolutely rediculous. The difference once you go from $99,999 to $100,001 is stupid. A 1kw system typically costs $12k, but only $4k on the rebate.. a 66.6% discount, thats rediculous. The people who earn over $100k have to pay 3 times as much, not to mention that its their taxes paying for the other people anyway. What the goverment doesn't understand is that the price of panels are largly set by the price of existing electricity. WIthout the repayment its about 20 years until it pays off, most studies show solar panels aren't even carbon neutral until 15 years, 30 years if the water used to make them comes from de-sal. They are just a joke - like water tanks.
