This post is about using the EverSolar PMU and AS Control plus some quirks I’ve come across when using them.
The post is mainly to do with having all the data stored in the PMU available for AS Control to display. Especially when a PC isn’t connected to the PMU 24/7 or when accessing the data remotely (off site). If you want to do a file import / export or look at graphs of past history AS Control uses the databases on the computer AS_Control is running on. If it hasn’t been logging live data for a while then there is not much data to look at, the only data stored on the PC is data collected while connected to the PMU when the PV System is running and the inverter is on.
My Inverter and PMU are in my garage and my 4 port wireless router is inside the house. Initially to get the PMU running I had to temporarily run a CAT5 network cable from the garage and into the house this was a pain and a trip hazard.
So off to eBay I went looking for a cheap wireless bridge. I settled on a Vonets VAP11G that cost me $28AUD delivered. It came with a disk and was easy to set up and so far has been working just fine.
The following images are screen shots of the graphs from Current Cost, Google Powermeter & AS Control.
They are all for the 17th May 2011. I took the screen shots at around 10pm, so the totals for the Current Cost and Google Powermeter graphs aren’t finalised due to the “always” on current due to the Inverter’s EMC filter that I mentioned in this post >> Monitoring via Current Cost and Google Powermeter.
In addition to using the EverSolar PMU to monitor my solar generation, I also have a Current Cost EnviR and Bridge installed. It uploads it data to the Current Cost Dashboard and that uploads the data to the Google Power meter.
I have an Eversolar TL1500AS inverter and a PMU.
I’ve been using a Current Cost “Classic” for over two years to monitor my house usage. I’ve been logging the data from that daily using Dale Lane’s “currentcost” software. I have a licence for the Techtoniq software but don’t use it as it really needs a PC on all the time which defeated the purpose IMHO. ( http://wotid.com/target4000/index.html )
I bought a Current Cost EnviR and Bridge for my inverter and linked it to the Current Cost dashboard and Google Power meter so I could monitor the system where ever and when ever I wanted.
