Carl Posted June 22, 2015 Share Posted June 22, 2015 Just read through the Axpert Inverter Manual and noticed the following efficiency specs: 1) Solar Charging Mode: 98 % (max eff.) 2) Inverter Mode: 90 % (peak eff.) So i assume that if solar is supplying the load the max efficiency will be 88 %. A minimum 10 % of battery capacity is lost, just by inverting the battery voltage to AC power. I would like to know if anyone has an idea of the inverter efficiencies at different output power ratings. Quote Link to comment Share on other sites More sharing options...
Chris Hobson Posted June 24, 2015 Share Posted June 24, 2015 The Imeon efficiency is in the order of 93-95%. The hybrid inverters are infinitely superior to the old linear PV -> Charge controller -> Batteries-> Inverter -> Load. You can use energy as you generate it. In the older system you had to store it first and suffer the inherent inefficiencies. Quote Link to comment Share on other sites More sharing options...
Carl Posted June 26, 2015 Author Share Posted June 26, 2015 Hi Chris, looking at the Axpert line diagram it seems to be the old inefficient way of doing things. The solar PV input is converted down to the battery voltage and then inverted back up to 230 Vac. Would love to know what the efficiency of this inverter is at different load levels.

Chris Hobson Posted June 26, 2015 Share Posted June 26, 2015 Hi Carl there is an Australian forum http://forums.aeva.asn.au/forums/forums.html. Some of the guys have taken their inverters apart, soldered in different resistors etc. They may well be able tell you more. Quote Link to comment Share on other sites More sharing options...
Carl Posted June 26, 2015 Author Share Posted June 26, 2015 Thanks Chris will check it out. Would love to hear about your interesting installation and how the Axpert deals with farm life. Quote Link to comment Share on other sites More sharing options...
Chris Hobson Posted June 26, 2015 Share Posted June 26, 2015 Plan to make a lot of progress this weekend. Perhaps have AC input and output and batteries wired up by Sunday. Quote Link to comment Share on other sites More sharing options...

Chris Hobson Posted July 4, 2015 Share Posted July 4, 2015 Please, keep up posted! Look at my Fastening PVs post in Solar Beginners first pictures Quote Link to comment Share on other sites More sharing options...
SilverNodashi Posted September 22, 2015 Share Posted September 22, 2015 Has anyone done some tests on this inverter to see how efficient it really is, both from a PV and batteries point of view? It would be interesting to see some charts. Unfortunately I don't have the equipment todo it myself. Quote Link to comment Share on other sites More sharing options...
