Howdy All,
I know this has been a little while coming but here it is. Firstly definitions on what a Hybrid solar system is will vary. I think this is the definition we will run with for now, until someone comes up with something better." A hybrid solar system is a grid tied solar PV system that also has battery storage".
My brother Andy has just built a new house on his block of land in the Adelaide hills. Andy owns Solar Wholesalers in Adelaide and is a part owner of our site sponsor www.solarreviews.com I mention this as the following system will not make sense to many people. Andy's house is large, very large and he wanted to design a system that would be big enough to run the daily day time load of the house while at the same time having enough solar to charge the batteries everyday as well. The reason is that we only have a FIT (feed in tarif) here of 4 cents per kilowatt hour feed back to the grid. So the plan is to run the house of the panels (well effectively anyway) during the day and run the house of the battery at night to avoid paying 36 cents per kilowatt hour from the grid.. Now our grid here is very reliable only a few power outages a year generally for less that 2 hours. We have no generator plugged into the system, however we can access a 12KVA genny at very short notice if required, (has one for the solar install business, its needed every now and again)
Ok so here are the stats and some photos.
30kW PV array, 120 x Sunrise SR-P660250 panels, ground mounted about 100 meters from the battery bunker next to the house.
Inverter's are Kaco 6kW x 3 and Kaco 3.3 x3
CC are Selectronic SP Pro 7.5kW x 3
Batteries, Kweight, VRLA, 2V, 1000amp x 60 ( basically cheap Chinese battery)
The system is 120V and is set as 3 x 10kW units so we can run 3 phase equipment.
There was some debate as to what to use but Andy trumped everyone as its his $$, just for the record I wanted to go with SMA.
We have been looking for a cheap battery for a while as more and more people inquire about it but for most it still dont make a lot of sense, so the theory is if we can find a reliable cheap battery we will sell them. We are doing this as a bit of an experiment as well.
The system is not turned on yet as we are waiting for a few more bits to turn up, but hopefully its going by next week. By the way we average about 4kW/hrs per kilowatt of installed capacity, so a 30kW system will average 120kW/hrs per day.
Ok photo,s wont upload? I'll have to work it out later, is there a trick to it?
