GivEnergy 3kW AC Coupled Inverter & SolarEdge SE6000 with PV Diverter

Hi,

I am really pleased with my GivEnergy system which was installed towards the end of last year, now that the Solar energy is increasing we are seeing a huge reduction in energy bills.

I'm running a mostly all electrical system now -

• LG Therma V Split - AWHP
• SolarEdge - 6kW (24 Panels) with SE6000 Inverter
• SolarEdge - SEHAZB-HEAT-CONT-3 (3kW PV Diverter controlled by SolarEdge Inverter)
• GivEnergy 3kW AC Coupled Inverter with 2 x 8.2kWh batteries

Given the mixture of technologies, specifically the SolarEdge and the GivEnergy I am trying to work out the best way to get things configured to run the most efficient system.

I can see that if the PV Divertor is left in Auto then it appears to pulse on and off for most of the time - not sure if it is reacting to excess supply faster than the charger can start to charge the battery... Ideally I would like to prioritise the charging of the batteries and then divert the excess to the hot water once the battery is at 100%, however, the SolarEdge API does not allow remote control of the PV divertor - I would need to try and do something via website screen scrape... Ugh!

I was wondering if anyone else is running a similar system and what experiences you had encountered?

Thanks in advance,

Andrew

My AC coupled system has an iBoost diverter. I find that when sun conditions vary quickly ( i.e. clouds "scudding" past the sun) then the rapid increase in solar output triggers the diverter before the Ge unit starts to charge the batteries. In " steady state" conditions that doesn't happen - the batteries get priority until fully charged and only then does the diverter come into play. I have increased the "offset" on the iBoost to 200W, that does help, but does not stop the problem completely.
It seems the response time of the iBoost is a lot quicker than the AC3.0.

Don't run solar Edge but if you can switch the diverter on and off via their webportal I'd use the developer tools (ctrl + shift + i) and monitor the network tab while your changing settings. It'll probably give you the call you need to mimic to save having to do a screen scraping exercise. (It's probably already in the solar Edge API just not documented)
Plus you can dump it into postman by exporting the call as: curl (Bash) super easy then.

hoggy I've had a look at this but am not really sure where to start - I can see a URL that it appears to poll to get the device state, however, trying to access this returns a '403 - Forbidden' so it looks like there is some authentication somewhere that I am missing... Whilst not the most elegant method I may have to look at Selenium and scraping the page :-(
