The small black item is the regulator. The green item is the Dump Resistor.
The Larger Black box holds the Terminal block,Amp Meter,Fuse and electrical
stop switch( which is a double throw). To do the job correctly
its quite a job. Also buying
the correct Regulator it comes in 12 or 24 volt. I reccomend the TB series and the Dump resistor is included.
The tech people are very helpful at LVMSHOP .
I bought from the LVMSHOP in england. It cost $50 for shipping
,plus VAT and then you are paying in British Pounds. I think the Dump resistor and Regulator was around $300 USD. However there was a place in Alaska
that offered a great price
on the items around $190. They were out of stock at the time and it seemed they were having some difficulty getting product. The website Alternative & Renewable Energy - ABS Alaskan
I wouldn't take any shotcuts in the installation
of the unit. In the least you could fry your batteries
. The worst is @#$%^&&. You know what I mean. Also be sure to have it up very high. The rotating blades have been known to seriously hurt or kill. I used a 8 foot by 2 inch diameter stainless pole with a support bar to reduce vibration. If you never had the chance to try to sleep with a constant vibration you will now. firstname.lastname@example.org
